US Navy investigates potential LCS class-wide design flaw

[westwall]

Seems like an electric propulsion system would have been far simpler, combining the power from turbines and diesels electrically instead of mechanically.

That makes zero sense, as all electric propulsion systems have mechanical parts

No shit, genius. Did you read the article? Did you comprehend it? They're trying to mechanically combine the output power from two diesel engines and two gas turbine engines through one complicated gearbox system. The gearbox is failing, and they don't understand why yet.

Imagine an electrical power plant with steam turbines and a large diesel generator. Are all the output shafts ganged together mechanically, or are the alternators from each unit ganged together electrically?

Hint: They're tied together electrically. Matter of fact, every generator online at any given moment feeding power to the national electrical grid are all tied together electrically...NOT mechanically.

My statement makes perfect sense. An electric drive system would be far simpler.

Dude there is no such thing as what you said which was. "combining the power from turbines and diesels electrically instead of mechanically." How does that happen?

So you have no idea what you are babbling about. But hey it sounded good right?

An electric ship can not charge at the charging station, they would need generators, batteries, and the fuel of an oil tanker to run these so it's impossible. So try again, this works in other situations because one oil drum of Uranium powers the ship for 20 years.

In WWII several classes of Destroyer Escorts used either diesel-electric, or turbo-electric drives without batteries or oil tankers to carry fuel. They displaced roughly a third of a LCS. It’s not new technology and generators coupled to electric motors are simpler and more fuel efficient than conventional geared drivetrains. That’s because the generators can always run at the optimum speed to power the motors.

Again the littoral ships have a high speed clutch bearing design flaw that encompasses the entire fleet of these ships. These ships can hit 50mph as designed. So the issue has nothing to do with either the diesel power or gas turbines, and if Daveman believes that his pieced together from the internet design is better than the current design and he is correct he will be a billionaire shortly. However all he is doing is quoting railroad technology that was invented 50 to 100 or even more years ago which has nothing to do with propelling a modern ship to 50mph today.

You are correct that electric ship power is not new, and for that reason precisely it has been tested and vetted as inefficient for various reasons, though it does work better in ships that have no need to be refueled as is the case with reactor equipped vessels, in submarines the electric motors can run off battery and be very quiet as there are no generators running to provide the power. So what works well in one situation does not necessarily work as well in another

Nuclear submarines don't ever run off batteries. the piles use radioactive hot water to heat non-radioactive cold water turning it into steam to turn a turbine that turn the prop and the exhaust steam from the turbine turns a generator to provide electrical power to the boat. That's the reason diesel electric boats are quieter than nuke boats when running on batteries. Don't you ever get tired of being wrong? Ten seconds of Google would stop you from looking like a fool.

He should take a little time to research before he posts. Most of the information is out there.

In fact, I would be happy to answer any submarine questions. I qualified in 1981 onboard an FBM submarine.

Qualified for what? Cook, laundry attendant, missile counter?

Again, a little research would do you some good.

To qualify on a submarine means having a working knowledge of every system on the boat and all damage control procedures and systems. You get signed off on every system, from NAV to propulsion, to supply requisitions. Then you have to stand in from of a board of both enlisted and officers and answer any question about anything on the boat. Then a walk-thru with the Capt. You would never be able to qualify.

I still have my "dolphins" and can still sign "SS" after my name on any military or veteran paperwork.

And every enlisted crewmember has a job, yours was what? Laundry like I said, or perhaps kitchen degreaser? Tell us pop

Yes, every enlisted crew member has a job. In addition to that job you stand various watches, from security watch in port to other jobs underway. I stood sonar watch and helmsman/planesman watch. And every crew member has to qualify. It usually takes months, because your various jobs still have to be done.

So let me get this straight, you watched the sonar man or driver do his job, but never did anything. So your job was absolutely nothing which is what your ASVAB test scores qualified you for.

Well at least you are honest

Yawn

I guess you never served in the military? Or you would know what the term "standing watch" means in this context.

I was the sonar man on watch, and I drove the boat.

Estella is a moron. They know nothing.

So were you a bubblehead, or on a DD?

I was a Bubblehead.

Which boat?

I have several friends who were bubblehead. Mostly attack subs, but one was on a boomer.

Boomers were great duty. More time off than anywhere else in the Navy. But also more time at sea. Never stopping in ports and only rarely surfacing.

Yeah, my attack friends were "3 knots to nowhere, no thanks!"

Thank you for helping keep this country safe!

Thank you.

Yeah, the boomers were not about excitement during the patrol. But when you are 400+ feet below the surface carrying more nuclear firepower than any vessel every carried, excitement seems over-rated. Smooth running and no water in the people tank is good.

Did you ever wish that you were assigned to an attack sub that actually had missions instead of doing absolutely nothing where you were?

Our mission was as a deterrent. We succeeded.

Perhaps you should step up and volunteer for sub duty.

He couldn't pass the psych eval., much less handle the training.

LOL I am 55 and can still do 100 mile cycle rides. Can't deadlift more than 400 lbs at this point anymore though my leg press still tops 1100

Yeah, good for you. Brute force and massive ignorance should be your calling card.

Submariners, on the other hand, being much smarter than you, follow the old adage, "work smarter, not harder".

A sonar specialist is a sonar specialist, period. Also the guy who drives the boat is less important than the cook.

Do you really want to continue?

So you are saying no one but a sonar specialist ever stands watch on sonar? lol

On a sub, the cooks are important. Especially the night baker. But no, the guys standing helmsman/planesman are kinda important. What boat was it your served on?

I am saying and correctly that Sonar technician is a specialty in the Navy, so were you a dedicated sonar technician?

Navy Enlisted Rating: Sonar Technician

BY
ROD POWERS
Updated March 15, 2019
In the Navy, Sonar Technician Surface Technicians (STGs) are a key part of what this branch of the U.S. Military does. They're responsible for underwater surveillance and help with navigation and search and rescue operations. Sonar is used by the Navy to detect, analyze, and locate targets of interest, so having qualified STGs to keep sonar systems and equipment in good operating condition is critical.

What Sonar Technicians Do in the Navy
Since sonar is used on surface ships such as frigates, minesweepers, destroyers, and cruisers as well as at remote locations throughout the world, there is no shortage of different types of work for these techs. They'll operate sonar sensors for detection and classification of contacts, and operate underwater fire control systems.

Sonar techs identify all manner of underwater sounds, including those produced by surface ships, torpedoes, submarines, evasion devices, jamming technologies, and other sonar transmissions (but including marine life and natural phenomena).

Once they've collected data, sonar technicians will analyze and interpret it, preparing and maintaining charts and plots. Some of the specialized equipment they use include bathythermographs and fathometers, as well as other recording devices.

Their training allows them to recognize major equipment malfunctions during sensor operations, perform preventive and corrective maintenance on sonar equipment and underwater fire control systems, and to identify electronic components on schematics and trace major signal flow.

STGs usually work indoors in clean, shop like environments and computer equipment rooms. They work closely with others and require little supervision.

A-School (Job School) Requirements for Sonar Technicians
Where Navy sonar techs go to training depends on which type of tech they're going to learn: surface, or submarine. For surface sonar technicians, they'll spend 10 weeks in "A" School in San Diego, after completing a six-week basic electronics course at the Great Lakes facility in Illinois.

After that, they'll attend class "C" School anywhere from 27 to 58 weeks in San Diego. The STG rating (which is what the Navy calls its jobs) requires a four-year service obligation, and for those in the Advanced Electronics Field training, a total obligation of six years of service.

For submarine class sonar technicians, a 37-week class "A" School training is required and takes place at the Navy facility in Groton, Connecticut.

Qualifications for Navy Sonar Technicians
To qualify for this rating, sailors need a combined score of 222 on the Arithmetic Reasoning (AR), Mathematics Knowledge (MK), Electronics Information (EI) and General Science (GS) sections of the Armed Services Vocational Aptitude Battery (ASVAB) test.

They need to be able to qualify for Secret security clearance and must have normal color perception and normal hearing. Sonar technicians in the Navy are required to be U.S. citizens.

Sub-Specialties Available for This Rating: Navy Enlisted Classification Codes for STG

And, on subs, other ratings stood sonar watch. The Secret Security clearance was required for every man onboard the sub.

What was your rating, now that we have determined that your ASVAB was insignificant for a sonar tech

Like you determined I am a smoker?

And now I have determined that you are afraid to tell us what your military job was.

I do this, what do you get paid to do?

I love special ed agents

I love having someone who never served tell me about what I did or didn't do, and which jobs are important.

I love fakers who do not have the guts to own up to what their military job actually was

I had the guts to step up and serve? How about you?

As for my rating, that is irrelevant to the discussion. And given the size of the crew, and since I have already said the name of my boat and crew, I prefer to keep my personal info from being spread around. But, even if I was a cook, a storekeeper, or a corpsman, the training I received and passed is beyond anything you could manage.

Where Navy sonar techs go to training depends on which type of tech they're going to learn: surface, or submarine. For surface sonar technicians, they'll spend 10 weeks in "A" School in San Diego, after completing a six-week basic electronics course at the Great Lakes facility in Illinois.

After that, they'll attend class "C" School anywhere from 27 to 58 weeks in San Diego. The STG rating (which is what the Navy calls its jobs) requires a four-year service obligation, and for those in the Advanced Electronics Field training, a total obligation of six years of service.

For submarine class sonar technicians, a 37-week class "A" School training is required and takes place at the Navy facility in Groton, Connecticut.

Qualifications for Navy Sonar Technicians
To qualify for this rating, sailors need a combined score of 222 on the Arithmetic Reasoning (AR), Mathematics Knowledge (MK), Electronics Information (EI) and General Science (GS) sections of the Armed Services Vocational Aptitude Battery (ASVAB) test.

They need to be able to qualify for Secret security clearance and must have normal color perception and normal hearing. Sonar technicians in the Navy are required to be U.S. citizens.

And, on subs, other ratings stood sonar watch. The Secret Security clearance was required for every man onboard the sub.

What was your rating, now that we have determined that your ASVAB was insignificant for a sonar tech

Like you determined I am a smoker?

And now I have determined that you are afraid to tell us what your military job was.

I do this, what do you get paid to do?

You have determined nothing. You are simply making a fool of yourself by making this personal.

Where did you serve?

Seems like an electric propulsion system would have been far simpler, combining the power from turbines and diesels electrically instead of mechanically.

That makes zero sense, as all electric propulsion systems have mechanical parts

No shit, genius. Did you read the article? Did you comprehend it? They're trying to mechanically combine the output power from two diesel engines and two gas turbine engines through one complicated gearbox system. The gearbox is failing, and they don't understand why yet.

Imagine an electrical power plant with steam turbines and a large diesel generator. Are all the output shafts ganged together mechanically, or are the alternators from each unit ganged together electrically?

Hint: They're tied together electrically. Matter of fact, every generator online at any given moment feeding power to the national electrical grid are all tied together electrically...NOT mechanically.

My statement makes perfect sense. An electric drive system would be far simpler.

Dude there is no such thing as what you said which was. "combining the power from turbines and diesels electrically instead of mechanically." How does that happen?

So you have no idea what you are babbling about. But hey it sounded good right?

An electric ship can not charge at the charging station, they would need generators, batteries, and the fuel of an oil tanker to run these so it's impossible. So try again, this works in other situations because one oil drum of Uranium powers the ship for 20 years.

In WWII several classes of Destroyer Escorts used either diesel-electric, or turbo-electric drives without batteries or oil tankers to carry fuel. They displaced roughly a third of a LCS. It’s not new technology and generators coupled to electric motors are simpler and more fuel efficient than conventional geared drivetrains. That’s because the generators can always run at the optimum speed to power the motors.

Again the littoral ships have a high speed clutch bearing design flaw that encompasses the entire fleet of these ships. These ships can hit 50mph as designed. So the issue has nothing to do with either the diesel power or gas turbines, and if Daveman believes that his pieced together from the internet design is better than the current design and he is correct he will be a billionaire shortly. However all he is doing is quoting railroad technology that was invented 50 to 100 or even more years ago which has nothing to do with propelling a modern ship to 50mph today.

You are correct that electric ship power is not new, and for that reason precisely it has been tested and vetted as inefficient for various reasons, though it does work better in ships that have no need to be refueled as is the case with reactor equipped vessels, in submarines the electric motors can run off battery and be very quiet as there are no generators running to provide the power. So what works well in one situation does not necessarily work as well in another

Nuclear submarines don't ever run off batteries. the piles use radioactive hot water to heat non-radioactive cold water turning it into steam to turn a turbine that turn the prop and the exhaust steam from the turbine turns a generator to provide electrical power to the boat. That's the reason diesel electric boats are quieter than nuke boats when running on batteries. Don't you ever get tired of being wrong? Ten seconds of Google would stop you from looking like a fool.

He should take a little time to research before he posts. Most of the information is out there.

In fact, I would be happy to answer any submarine questions. I qualified in 1981 onboard an FBM submarine.

Qualified for what? Cook, laundry attendant, missile counter?

Again, a little research would do you some good.

To qualify on a submarine means having a working knowledge of every system on the boat and all damage control procedures and systems. You get signed off on every system, from NAV to propulsion, to supply requisitions. Then you have to stand in from of a board of both enlisted and officers and answer any question about anything on the boat. Then a walk-thru with the Capt. You would never be able to qualify.

I still have my "dolphins" and can still sign "SS" after my name on any military or veteran paperwork.

And every enlisted crewmember has a job, yours was what? Laundry like I said, or perhaps kitchen degreaser? Tell us pop

Yes, every enlisted crew member has a job. In addition to that job you stand various watches, from security watch in port to other jobs underway. I stood sonar watch and helmsman/planesman watch. And every crew member has to qualify. It usually takes months, because your various jobs still have to be done.

So let me get this straight, you watched the sonar man or driver do his job, but never did anything. So your job was absolutely nothing which is what your ASVAB test scores qualified you for.

Well at least you are honest

Yawn

I guess you never served in the military? Or you would know what the term "standing watch" means in this context.

I was the sonar man on watch, and I drove the boat.

Estella is a moron. They know nothing.

So were you a bubblehead, or on a DD?

I was a Bubblehead.

Which boat?

I have several friends who were bubblehead. Mostly attack subs, but one was on a boomer.

Boomers were great duty. More time off than anywhere else in the Navy. But also more time at sea. Never stopping in ports and only rarely surfacing.

Yeah, my attack friends were "3 knots to nowhere, no thanks!"

Thank you for helping keep this country safe!

Thank you.

Yeah, the boomers were not about excitement during the patrol. But when you are 400+ feet below the surface carrying more nuclear firepower than any vessel every carried, excitement seems over-rated. Smooth running and no water in the people tank is good.

Did you ever wish that you were assigned to an attack sub that actually had missions instead of doing absolutely nothing where you were?

Our mission was as a deterrent. We succeeded.

Perhaps you should step up and volunteer for sub duty.

LOL are you aware that not all submarine crew members volunteer as some are picked for the job before they ever set foot in the Navy?

Out-Interviewing the Interviewer: A Job... book by Stephen K. Merman (thriftbooks.com)

I love special ed agents

I love having someone who never served tell me about what I did or didn't do, and which jobs are important.

I love fakers who do not have the guts to own up to what their military job actually was

I had the guts to step up and serve? How about you?

As for my rating, that is irrelevant to the discussion. And given the size of the crew, and since I have already said the name of my boat and crew, I prefer to keep my personal info from being spread around. But, even if I was a cook, a storekeeper, or a corpsman, the training I received and passed is beyond anything you could manage.

What weapons does the military make? See if not for the rest of the population there would be no military.

Continue on

LOL I bought Raytheon does that count?

Yeah, good for you. Brute force and massive ignorance should be your calling card.

Submariners, on the other hand, being much smarter than you, follow the old adage, "work smarter, not harder".

Ask the FBI who is smarter than me?

Whaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

I could expand on that, but then I would have to kill you, and I like you because you are funny

What? The FBI would probably say you are some low level criminal dumbass, fetching booze for your master and cleaning up his dogs shit when you walk him.

You're a wannabe tough guy. That's obvious as hell. It's also obvious you are eastern European, and not very smart.

A sonar specialist is a sonar specialist, period. Also the guy who drives the boat is less important than the cook.

Do you really want to continue?

So you are saying no one but a sonar specialist ever stands watch on sonar? lol

On a sub, the cooks are important. Especially the night baker. But no, the guys standing helmsman/planesman are kinda important. What boat was it your served on?

I am saying and correctly that Sonar technician is a specialty in the Navy, so were you a dedicated sonar technician?

Navy Enlisted Rating: Sonar Technician (thebalancecareers.com)


Navy Enlisted Rating: Sonar Technician

BY
ROD POWERS
Updated March 15, 2019
In the Navy, Sonar Technician Surface Technicians (STGs) are a key part of what this branch of the U.S. Military does. They're responsible for underwater surveillance and help with navigation and search and rescue operations. Sonar is used by the Navy to detect, analyze, and locate targets of interest, so having qualified STGs to keep sonar systems and equipment in good operating condition is critical.

What Sonar Technicians Do in the Navy
Since sonar is used on surface ships such as frigates, minesweepers, destroyers, and cruisers as well as at remote locations throughout the world, there is no shortage of different types of work for these techs. They'll operate sonar sensors for detection and classification of contacts, and operate underwater fire control systems.

Sonar techs identify all manner of underwater sounds, including those produced by surface ships, torpedoes, submarines, evasion devices, jamming technologies, and other sonar transmissions (but including marine life and natural phenomena).

Once they've collected data, sonar technicians will analyze and interpret it, preparing and maintaining charts and plots. Some of the specialized equipment they use include bathythermographs and fathometers, as well as other recording devices.

Their training allows them to recognize major equipment malfunctions during sensor operations, perform preventive and corrective maintenance on sonar equipment and underwater fire control systems, and to identify electronic components on schematics and trace major signal flow.

STGs usually work indoors in clean, shop like environments and computer equipment rooms. They work closely with others and require little supervision.

A-School (Job School) Requirements for Sonar Technicians
Where Navy sonar techs go to training depends on which type of tech they're going to learn: surface, or submarine. For surface sonar technicians, they'll spend 10 weeks in "A" School in San Diego, after completing a six-week basic electronics course at the Great Lakes facility in Illinois.

I still have my "dolphins" and can still sign "SS" after my name on any military or veteran paperwork.

And every enlisted crewmember has a job, yours was what? Laundry like I said, or perhaps kitchen degreaser? Tell us pop

Yes, every enlisted crew member has a job. In addition to that job you stand various watches, from security watch in port to other jobs underway. I stood sonar watch and helmsman/planesman watch. And every crew member has to qualify. It usually takes months, because your various jobs still have to be done.

So let me get this straight, you watched the sonar man or driver do his job, but never did anything. So your job was absolutely nothing which is what your ASVAB test scores qualified you for.

Well at least you are honest

Yawn

I guess you never served in the military? Or you would know what the term "standing watch" means in this context.

I was the sonar man on watch, and I drove the boat.

Estella is a moron. They know nothing.

So were you a bubblehead, or on a DD?

I was a Bubblehead.

Which boat?

I have several friends who were bubblehead. Mostly attack subs, but one was on a boomer.

Boomers were great duty. More time off than anywhere else in the Navy. But also more time at sea. Never stopping in ports and only rarely surfacing.

Yeah, my attack friends were "3 knots to nowhere, no thanks!"

Thank you for helping keep this country safe!

Thank you.

Yeah, the boomers were not about excitement during the patrol. But when you are 400+ feet below the surface carrying more nuclear firepower than any vessel every carried, excitement seems over-rated. Smooth running and no water in the people tank is good.

Did you ever wish that you were assigned to an attack sub that actually had missions instead of doing absolutely nothing where you were?

Our mission was as a deterrent. We succeeded.

Perhaps you should step up and volunteer for sub duty.

He couldn't pass the psych eval., much less handle the training.

LOL I am 55 and can still do 100 mile cycle rides. Can't deadlift more than 400 lbs at this point anymore though my leg press still tops 1100

Yeah, good for you. Brute force and massive ignorance should be your calling card.

Submariners, on the other hand, being much smarter than you, follow the old adage, "work smarter, not harder".

Ask the FBI who is smarter than me?

Whaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

I could expand on that, but then I would have to kill you, and I like you because you are funny

Sad. You post what you claim are facts, and when you get corrected by people who actually know, you resort to personal attacks.

Seems like an electric propulsion system would have been far simpler, combining the power from turbines and diesels electrically instead of mechanically.

That makes zero sense, as all electric propulsion systems have mechanical parts

No shit, genius. Did you read the article? Did you comprehend it? They're trying to mechanically combine the output power from two diesel engines and two gas turbine engines through one complicated gearbox system. The gearbox is failing, and they don't understand why yet.

Imagine an electrical power plant with steam turbines and a large diesel generator. Are all the output shafts ganged together mechanically, or are the alternators from each unit ganged together electrically?

Hint: They're tied together electrically. Matter of fact, every generator online at any given moment feeding power to the national electrical grid are all tied together electrically...NOT mechanically.

My statement makes perfect sense. An electric drive system would be far simpler.

Dude there is no such thing as what you said which was. "combining the power from turbines and diesels electrically instead of mechanically." How does that happen?

So you have no idea what you are babbling about. But hey it sounded good right?

An electric ship can not charge at the charging station, they would need generators, batteries, and the fuel of an oil tanker to run these so it's impossible. So try again, this works in other situations because one oil drum of Uranium powers the ship for 20 years.

In WWII several classes of Destroyer Escorts used either diesel-electric, or turbo-electric drives without batteries or oil tankers to carry fuel. They displaced roughly a third of a LCS. It’s not new technology and generators coupled to electric motors are simpler and more fuel efficient than conventional geared drivetrains. That’s because the generators can always run at the optimum speed to power the motors.

Again the littoral ships have a high speed clutch bearing design flaw that encompasses the entire fleet of these ships. These ships can hit 50mph as designed. So the issue has nothing to do with either the diesel power or gas turbines, and if Daveman believes that his pieced together from the internet design is better than the current design and he is correct he will be a billionaire shortly. However all he is doing is quoting railroad technology that was invented 50 to 100 or even more years ago which has nothing to do with propelling a modern ship to 50mph today.

You are correct that electric ship power is not new, and for that reason precisely it has been tested and vetted as inefficient for various reasons, though it does work better in ships that have no need to be refueled as is the case with reactor equipped vessels, in submarines the electric motors can run off battery and be very quiet as there are no generators running to provide the power. So what works well in one situation does not necessarily work as well in another

Nuclear submarines don't ever run off batteries. the piles use radioactive hot water to heat non-radioactive cold water turning it into steam to turn a turbine that turn the prop and the exhaust steam from the turbine turns a generator to provide electrical power to the boat. That's the reason diesel electric boats are quieter than nuke boats when running on batteries. Don't you ever get tired of being wrong? Ten seconds of Google would stop you from looking like a fool.

He should take a little time to research before he posts. Most of the information is out there.

In fact, I would be happy to answer any submarine questions. I qualified in 1981 onboard an FBM submarine.

Qualified for what? Cook, laundry attendant, missile counter?

Again, a little research would do you some good.

To qualify on a submarine means having a working knowledge of every system on the boat and all damage control procedures and systems. You get signed off on every system, from NAV to propulsion, to supply requisitions. Then you have to stand in from of a board of both enlisted and officers and answer any question about anything on the boat. Then a walk-thru with the Capt. You would never be able to qualify.

I still have my "dolphins" and can still sign "SS" after my name on any military or veteran paperwork.

A sonar specialist is a sonar specialist, period. Also the guy who drives the boat is less important than the cook.

Do you really want to continue?

So you are saying no one but a sonar specialist ever stands watch on sonar? lol

On a sub, the cooks are important. Especially the night baker. But no, the guys standing helmsman/planesman are kinda important. What boat was it your served on?

I am saying and correctly that Sonar technician is a specialty in the Navy, so were you a dedicated sonar technician?

Navy Enlisted Rating: Sonar Technician

BY
ROD POWERS
Updated March 15, 2019
In the Navy, Sonar Technician Surface Technicians (STGs) are a key part of what this branch of the U.S. Military does. They're responsible for underwater surveillance and help with navigation and search and rescue operations. Sonar is used by the Navy to detect, analyze, and locate targets of interest, so having qualified STGs to keep sonar systems and equipment in good operating condition is critical.

What Sonar Technicians Do in the Navy
Since sonar is used on surface ships such as frigates, minesweepers, destroyers, and cruisers as well as at remote locations throughout the world, there is no shortage of different types of work for these techs. They'll operate sonar sensors for detection and classification of contacts, and operate underwater fire control systems.

Sonar techs identify all manner of underwater sounds, including those produced by surface ships, torpedoes, submarines, evasion devices, jamming technologies, and other sonar transmissions (but including marine life and natural phenomena).

Once they've collected data, sonar technicians will analyze and interpret it, preparing and maintaining charts and plots. Some of the specialized equipment they use include bathythermographs and fathometers, as well as other recording devices.

Their training allows them to recognize major equipment malfunctions during sensor operations, perform preventive and corrective maintenance on sonar equipment and underwater fire control systems, and to identify electronic components on schematics and trace major signal flow.

STGs usually work indoors in clean, shop like environments and computer equipment rooms. They work closely with others and require little supervision.

A-School (Job School) Requirements for Sonar Technicians
Where Navy sonar techs go to training depends on which type of tech they're going to learn: surface, or submarine. For surface sonar technicians, they'll spend 10 weeks in "A" School in San Diego, after completing a six-week basic electronics course at the Great Lakes facility in Illinois.

After that, they'll attend class "C" School anywhere from 27 to 58 weeks in San Diego. The STG rating (which is what the Navy calls its jobs) requires a four-year service obligation, and for those in the Advanced Electronics Field training, a total obligation of six years of service.

For submarine class sonar technicians, a 37-week class "A" School training is required and takes place at the Navy facility in Groton, Connecticut.

Qualifications for Navy Sonar Technicians
To qualify for this rating, sailors need a combined score of 222 on the Arithmetic Reasoning (AR), Mathematics Knowledge (MK), Electronics Information (EI) and General Science (GS) sections of the Armed Services Vocational Aptitude Battery (ASVAB) test.

They need to be able to qualify for Secret security clearance and must have normal color perception and normal hearing. Sonar technicians in the Navy are required to be U.S. citizens.

Sub-Specialties Available for This Rating: Navy Enlisted Classification Codes for STG

And, on subs, other ratings stood sonar watch. The Secret Security clearance was required for every man onboard the sub.

What was your rating, now that we have determined that your ASVAB was insignificant for a sonar tech

Like you determined I am a smoker?

And now I have determined that you are afraid to tell us what your military job was.

I do this, what do you get paid to do?

You have determined nothing. You are simply making a fool of yourself by making this personal.

Where did you serve?

Unfortunately that is actually top secret SCI

Out-Interviewing the Interviewer: A Job... book by Stephen K. Merman (thriftbooks.com)

I love special ed agents

I love having someone who never served tell me about what I did or didn't do, and which jobs are important.

I love fakers who do not have the guts to own up to what their military job actually was

I had the guts to step up and serve? How about you?

As for my rating, that is irrelevant to the discussion. And given the size of the crew, and since I have already said the name of my boat and crew, I prefer to keep my personal info from being spread around. But, even if I was a cook, a storekeeper, or a corpsman, the training I received and passed is beyond anything you could manage.

Imagine an electrical power plant with steam turbines and a large diesel generator. Are all the output shafts ganged together mechanically, or are the alternators from each unit ganged together electrically?

Hint: They're tied together electrically. Matter of fact, every generator online at any given moment feeding power to the national electrical grid are all tied together electrically...NOT mechanically.

My statement makes perfect sense. An electric drive system would be far simpler.

Dude there is no such thing as what you said which was. "combining the power from turbines and diesels electrically instead of mechanically." How does that happen?

So you have no idea what you are babbling about. But hey it sounded good right?

An electric ship can not charge at the charging station, they would need generators, batteries, and the fuel of an oil tanker to run these so it's impossible. So try again, this works in other situations because one oil drum of Uranium powers the ship for 20 years.

In WWII several classes of Destroyer Escorts used either diesel-electric, or turbo-electric drives without batteries or oil tankers to carry fuel. They displaced roughly a third of a LCS. It’s not new technology and generators coupled to electric motors are simpler and more fuel efficient than conventional geared drivetrains. That’s because the generators can always run at the optimum speed to power the motors.

Again the littoral ships have a high speed clutch bearing design flaw that encompasses the entire fleet of these ships. These ships can hit 50mph as designed. So the issue has nothing to do with either the diesel power or gas turbines, and if Daveman believes that his pieced together from the internet design is better than the current design and he is correct he will be a billionaire shortly. However all he is doing is quoting railroad technology that was invented 50 to 100 or even more years ago which has nothing to do with propelling a modern ship to 50mph today.

You are correct that electric ship power is not new, and for that reason precisely it has been tested and vetted as inefficient for various reasons, though it does work better in ships that have no need to be refueled as is the case with reactor equipped vessels, in submarines the electric motors can run off battery and be very quiet as there are no generators running to provide the power. So what works well in one situation does not necessarily work as well in another

Nuclear submarines don't ever run off batteries. the piles use radioactive hot water to heat non-radioactive cold water turning it into steam to turn a turbine that turn the prop and the exhaust steam from the turbine turns a generator to provide electrical power to the boat. That's the reason diesel electric boats are quieter than nuke boats when running on batteries. Don't you ever get tired of being wrong? Ten seconds of Google would stop you from looking like a fool.

He should take a little time to research before he posts. Most of the information is out there.

In fact, I would be happy to answer any submarine questions. I qualified in 1981 onboard an FBM submarine.

Qualified for what? Cook, laundry attendant, missile counter?

Again, a little research would do you some good.

To qualify on a submarine means having a working knowledge of every system on the boat and all damage control procedures and systems. You get signed off on every system, from NAV to propulsion, to supply requisitions. Then you have to stand in from of a board of both enlisted and officers and answer any question about anything on the boat. Then a walk-thru with the Capt. You would never be able to qualify.

I still have my "dolphins" and can still sign "SS" after my name on any military or veteran paperwork.

And every enlisted crewmember has a job, yours was what? Laundry like I said, or perhaps kitchen degreaser? Tell us pop

Yes, every enlisted crew member has a job. In addition to that job you stand various watches, from security watch in port to other jobs underway. I stood sonar watch and helmsman/planesman watch. And every crew member has to qualify. It usually takes months, because your various jobs still have to be done.

So let me get this straight, you watched the sonar man or driver do his job, but never did anything. So your job was absolutely nothing which is what your ASVAB test scores qualified you for.

Well at least you are honest

Yawn

I guess you never served in the military? Or you would know what the term "standing watch" means in this context.

I was the sonar man on watch, and I drove the boat.

A sonar specialist is a sonar specialist, period. Also the guy who drives the boat is less important than the cook.

Do you really want to continue?

So you are saying no one but a sonar specialist ever stands watch on sonar? lol

On a sub, the cooks are important. Especially the night baker. But no, the guys standing helmsman/planesman are kinda important. What boat was it your served on?

I am saying and correctly that Sonar technician is a specialty in the Navy, so were you a dedicated sonar technician?

Navy Enlisted Rating: Sonar Technician (thebalancecareers.com)


Navy Enlisted Rating: Sonar Technician

BY
ROD POWERS
Updated March 15, 2019
In the Navy, Sonar Technician Surface Technicians (STGs) are a key part of what this branch of the U.S. Military does. They're responsible for underwater surveillance and help with navigation and search and rescue operations. Sonar is used by the Navy to detect, analyze, and locate targets of interest, so having qualified STGs to keep sonar systems and equipment in good operating condition is critical.

What Sonar Technicians Do in the Navy
Since sonar is used on surface ships such as frigates, minesweepers, destroyers, and cruisers as well as at remote locations throughout the world, there is no shortage of different types of work for these techs. They'll operate sonar sensors for detection and classification of contacts, and operate underwater fire control systems.

Sonar techs identify all manner of underwater sounds, including those produced by surface ships, torpedoes, submarines, evasion devices, jamming technologies, and other sonar transmissions (but including marine life and natural phenomena).

Once they've collected data, sonar technicians will analyze and interpret it, preparing and maintaining charts and plots. Some of the specialized equipment they use include bathythermographs and fathometers, as well as other recording devices.

Their training allows them to recognize major equipment malfunctions during sensor operations, perform preventive and corrective maintenance on sonar equipment and underwater fire control systems, and to identify electronic components on schematics and trace major signal flow.

STGs usually work indoors in clean, shop like environments and computer equipment rooms. They work closely with others and require little supervision.

A-School (Job School) Requirements for Sonar Technicians
Where Navy sonar techs go to training depends on which type of tech they're going to learn: surface, or submarine. For surface sonar technicians, they'll spend 10 weeks in "A" School in San Diego, after completing a six-week basic electronics course at the Great Lakes facility in Illinois.

After that, they'll attend class "C" School anywhere from 27 to 58 weeks in San Diego. The STG rating (which is what the Navy calls its jobs) requires a four-year service obligation, and for those in the Advanced Electronics Field training, a total obligation of six years of service.

For submarine class sonar technicians, a 37-week class "A" School training is required and takes place at the Navy facility in Groton, Connecticut.

Qualifications for Navy Sonar Technicians
To qualify for this rating, sailors need a combined score of 222 on the Arithmetic Reasoning (AR), Mathematics Knowledge (MK), Electronics Information (EI) and General Science (GS) sections of the Armed Services Vocational Aptitude Battery (ASVAB) test.

They need to be able to qualify for Secret security clearance and must have normal color perception and normal hearing. Sonar technicians in the Navy are required to be U.S. citizens.

Sub-Specialties Available for This Rating: Navy Enlisted Classification Codes for STG

And, on subs, other ratings stood sonar watch. The Secret Security clearance was required for every man onboard the sub.

What was your rating, now that we have determined that your ASVAB was insignificant for a sonar tech

Like you determined I am a smoker?

And now I have determined that you are afraid to tell us what your military job was.

I do this, what do you get paid to do?

You have determined nothing. You are simply making a fool of yourself by making this personal.

Where did you serve?

Unfortunately that is actually top secret SCI

Actually, what branch you served in is not classified.

Actually not all people with top secret SCI clearances served?

Never said they did. I simply asked where you served and you replied with some nonsense about a security clearance.

So you never served? lol Figures.

Estella is a moron. They know nothing.

So were you a bubblehead, or on a DD?

I was a Bubblehead.

Which boat?

I have several friends who were bubblehead. Mostly attack subs, but one was on a boomer.

Boomers were great duty. More time off than anywhere else in the Navy. But also more time at sea. Never stopping in ports and only rarely surfacing.

Yeah, my attack friends were "3 knots to nowhere, no thanks!"

Thank you for helping keep this country safe!

Thank you.

Yeah, the boomers were not about excitement during the patrol. But when you are 400+ feet below the surface carrying more nuclear firepower than any vessel every carried, excitement seems over-rated. Smooth running and no water in the people tank is good.

Did you ever wish that you were assigned to an attack sub that actually had missions instead of doing absolutely nothing where you were?

Our mission was as a deterrent. We succeeded.

Perhaps you should step up and volunteer for sub duty.

LOL are you aware that not all submarine crew members volunteer as some are picked for the job before they ever set foot in the Navy?

Out-Interviewing the Interviewer: A Job... book by Stephen K. Merman (thriftbooks.com)

I love special ed agents

I love having someone who never served tell me about what I did or didn't do, and which jobs are important.

I love fakers who do not have the guts to own up to what their military job actually was

I had the guts to step up and serve? How about you?

As for my rating, that is irrelevant to the discussion. And given the size of the crew, and since I have already said the name of my boat and crew, I prefer to keep my personal info from being spread around. But, even if I was a cook, a storekeeper, or a corpsman, the training I received and passed is beyond anything you could manage.

What weapons does the military make? See if not for the rest of the population there would be no military.

LOL I bought Raytheon does that count?

That is true. Please tell us about how bravely you worked an assembly line making munitions.

Nah I bought Apple and Google

Yeah, good for you. Brute force and massive ignorance should be your calling card.

Submariners, on the other hand, being much smarter than you, follow the old adage, "work smarter, not harder".

Ask the FBI who is smarter than me?

Whaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

I could expand on that, but then I would have to kill you, and I like you because you are funny

Sad. You post what you claim are facts, and when you get corrected by people who actually know, you resort to personal attacks.

LOL I can back anything I say with unclassified Navy info from the web, and you still do not have the nerve to post to the group what your sub rank and or job was

It's ok someone has to wash the dishes

Yes, someone has to wash the dishes. On a submarine. While they also stand watches and qualify in their "spare" time. While they are in a dangerous situation and totally without contact with their family for months at a time.

Boomers were great duty. More time off than anywhere else in the Navy. But also more time at sea. Never stopping in ports and only rarely surfacing.

Yeah, my attack friends were "3 knots to nowhere, no thanks!"

Thank you for helping keep this country safe!

Thank you.

Yeah, the boomers were not about excitement during the patrol. But when you are 400+ feet below the surface carrying more nuclear firepower than any vessel every carried, excitement seems over-rated. Smooth running and no water in the people tank is good.

Did you ever wish that you were assigned to an attack sub that actually had missions instead of doing absolutely nothing where you were?

Our mission was as a deterrent. We succeeded.

Perhaps you should step up and volunteer for sub duty.

He couldn't pass the psych eval., much less handle the training.

LOL I am 55 and can still do 100 mile cycle rides. Can't deadlift more than 400 lbs at this point anymore though my leg press still tops 1100

Yeah, good for you. Brute force and massive ignorance should be your calling card.

Submariners, on the other hand, being much smarter than you, follow the old adage, "work smarter, not harder".

Ask the FBI who is smarter than me?

Whaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

I could expand on that, but then I would have to kill you, and I like you because you are funny

Sad. You post what you claim are facts, and when you get corrected by people who actually know, you resort to personal attacks.

LOL I can back anything I say with unclassified Navy info from the web, and you still do not have the nerve to post to the group what your sub rank and or job was

It's ok someone has to wash the dishes

Yes, someone has to wash the dishes. On a submarine. While they also stand watches and qualify in their "spare" time. While they are in a dangerous situation and totally without contact with their family for months at a time.

Just tell us what your rank and official job was on the sub. Wait were you the guard standing watch over the hatch at 400 feet?

Seems like an electric propulsion system would have been far simpler, combining the power from turbines and diesels electrically instead of mechanically.

That makes zero sense, as all electric propulsion systems have mechanical parts

No shit, genius. Did you read the article? Did you comprehend it? They're trying to mechanically combine the output power from two diesel engines and two gas turbine engines through one complicated gearbox system. The gearbox is failing, and they don't understand why yet.

Imagine an electrical power plant with steam turbines and a large diesel generator. Are all the output shafts ganged together mechanically, or are the alternators from each unit ganged together electrically?

Hint: They're tied together electrically. Matter of fact, every generator online at any given moment feeding power to the national electrical grid are all tied together electrically...NOT mechanically.

My statement makes perfect sense. An electric drive system would be far simpler.

Dude there is no such thing as what you said which was. "combining the power from turbines and diesels electrically instead of mechanically." How does that happen?

So you have no idea what you are babbling about. But hey it sounded good right?

An electric ship can not charge at the charging station, they would need generators, batteries, and the fuel of an oil tanker to run these so it's impossible. So try again, this works in other situations because one oil drum of Uranium powers the ship for 20 years.

In WWII several classes of Destroyer Escorts used either diesel-electric, or turbo-electric drives without batteries or oil tankers to carry fuel. They displaced roughly a third of a LCS. It’s not new technology and generators coupled to electric motors are simpler and more fuel efficient than conventional geared drivetrains. That’s because the generators can always run at the optimum speed to power the motors.

Again the littoral ships have a high speed clutch bearing design flaw that encompasses the entire fleet of these ships. These ships can hit 50mph as designed. So the issue has nothing to do with either the diesel power or gas turbines, and if Daveman believes that his pieced together from the internet design is better than the current design and he is correct he will be a billionaire shortly. However all he is doing is quoting railroad technology that was invented 50 to 100 or even more years ago which has nothing to do with propelling a modern ship to 50mph today.

You are correct that electric ship power is not new, and for that reason precisely it has been tested and vetted as inefficient for various reasons, though it does work better in ships that have no need to be refueled as is the case with reactor equipped vessels, in submarines the electric motors can run off battery and be very quiet as there are no generators running to provide the power. So what works well in one situation does not necessarily work as well in another

Nuclear submarines don't ever run off batteries. the piles use radioactive hot water to heat non-radioactive cold water turning it into steam to turn a turbine that turn the prop and the exhaust steam from the turbine turns a generator to provide electrical power to the boat. That's the reason diesel electric boats are quieter than nuke boats when running on batteries. Don't you ever get tired of being wrong? Ten seconds of Google would stop you from looking like a fool.

He should take a little time to research before he posts. Most of the information is out there.

In fact, I would be happy to answer any submarine questions. I qualified in 1981 onboard an FBM submarine.

Qualified for what? Cook, laundry attendant, missile counter?

Again, a little research would do you some good.

To qualify on a submarine means having a working knowledge of every system on the boat and all damage control procedures and systems. You get signed off on every system, from NAV to propulsion, to supply requisitions. Then you have to stand in from of a board of both enlisted and officers and answer any question about anything on the boat. Then a walk-thru with the Capt. You would never be able to qualify.

I still have my "dolphins" and can still sign "SS" after my name on any military or veteran paperwork.

And every enlisted crewmember has a job, yours was what? Laundry like I said, or perhaps kitchen degreaser? Tell us pop

Yes, every enlisted crew member has a job. In addition to that job you stand various watches, from security watch in port to other jobs underway. I stood sonar watch and helmsman/planesman watch. And every crew member has to qualify. It usually takes months, because your various jobs still have to be done.

So let me get this straight, you watched the sonar man or driver do his job, but never did anything. So your job was absolutely nothing which is what your ASVAB test scores qualified you for.

Well at least you are honest

Yawn

I guess you never served in the military? Or you would know what the term "standing watch" means in this context.

I was the sonar man on watch, and I drove the boat.

Estella is a moron. They know nothing.

So were you a bubblehead, or on a DD?

I was a Bubblehead.

I have several friends who were bubblehead. Mostly attack subs, but one was on a boomer.

LOL are you aware that not all submarine crew members volunteer as some are picked for the job before they ever set foot in the Navy?

Out-Interviewing the Interviewer: A Job... book by Stephen K. Merman (thriftbooks.com)

I love special ed agents

I love having someone who never served tell me about what I did or didn't do, and which jobs are important.

I love fakers who do not have the guts to own up to what their military job actually was

I had the guts to step up and serve? How about you?

As for my rating, that is irrelevant to the discussion. And given the size of the crew, and since I have already said the name of my boat and crew, I prefer to keep my personal info from being spread around. But, even if I was a cook, a storekeeper, or a corpsman, the training I received and passed is beyond anything you could manage.

What weapons does the military make? See if not for the rest of the population there would be no military.

Continue on

LOL I bought Raytheon does that count?

That is true. Please tell us about how bravely you worked an assembly line making munitions.

Nah I bought Apple and Google

How about you genius

I served.

So you were the cook serving meals...............................

I hear the cooks on some subs serve sloppy waffles, was that you?
