Ok fine it's a container ship and there are more than one radar guys. Can you offer us any idea how this happens and why a Destroyer would be unable to detect or evade the ship?
There are always possibilities..........doubtful at best................could have had power problems.....Radar could have malfunctioned..............but they have more than one radar.............The ship could have just gotten underway..........I don't know.........and the crew may have tied one on.................Hungover...........Low visibility.............engine malfunctions causing it to go dead in the water...............
There are other possible issues..............but highly unlikely.
Pure speculation is all you have.
I can relate a personal experience.
In about 1987, we were transiting an area south of the Straits of Messina (think where the boot of Italy kicks Sicily) on a guided missile cruiser which was 547 feet long.
I was the watch officer in the Combat Information Center and my best friend was the officer of the deck (OOD) on the bridge. This was my second Med deployment and I had been on board about 2 years.
There was a small intermittent radar contact approaching us from the south as most of the major traffic flowed north towards the straits.. We were headed southeast and my watch team was tracking about 20 radar contacts at the time. The weather was clear and visibility was good.
This radar contact would pop up for a few sweeps of the radar and then disappear for a few minutes, only to pop up back again. Both a scope plot and maneuvering board solution showed that it was close to a constant bearing - decreasing range contact (CBDR) or a collision course, but it was still many miles off. It continued to pop-up and disappear for about the next 20 minutes of so. I had already designated the track and we were watching it closely. I informed the watch supervisor I was going to the bridge to confer with the OOD. We should have had a visual on his port running light with the track they were following. No one saw a thing, so I returned back to CIC.
As the minutes wore on, the contact continued to pop up and then disappear. Finally, I decided to go back to the bridge to see that the watch could see, as they were still reporting no visual on the contact. Looking for myself, I was finally able to make out a white light directly ahead. As I told the ODD, what I saw, I continued looking to the starboard side and saw another white light. This made no sense, as the only white light we should be seeing would be if we were behind him. I walked out on the bridge wing for a better look with my OOD following me.
The next thing we saw still scares me to this day. A very large container ship, not unlike the one involved in the collision with the USS Fitzgerald, was dead ahead at a range of about 200 yards. It was showing lights as though it was anchored, in waters far too deep to have been anchored, but moving at about 15 knots. Because our paths were almost perpendicular, we passed just behind him with a clearance of about 50 yards. We had taken no action to change course as would have been required because we simply did not know what was out there. Why such a large ship failed to show up visibly or even on radar made no sense. I believe they were running with the wrong lights or or they had turned them off completely until right before we got too close for comfort.
I will be really interested in seeing why the container ship in this instance apparently doubled back on it's track not once, but twice. The investigation will find out what happened.
