I was involved in the first forward operating F-15A Base at Bitburg, AB. Here's a bit of info on the original F-15A. The guns were tied directly into the radar with no way to use it if you lost radar. And so were both types of missiles, the Aim-7 and the Aim-9. Don't get me wrong, when the radar was operating, there were nothing that could compete with it. The problem is, the Radar had a 33 percent rate of operation. That sounds bad. Well, it is. And we had mostly new pilots.
Enter Soderstrom with their F-4Es and Gs. And enter the war games.
We generated our F-15A models at a 33% rate. Meaning, 2/3rds of our bright and shining fighters scrubbed the missions normally due to a radar malfunction which left the F-15A as a single seat joy riding bird that costs tens of millions. Sounds bad, right?
The F-4E had the ability to fire it's heat seekers and guns without affecting the radar. Yes, having radar made them work better but the installed one thing from the Gun and Rod Shops and that was weaver 4 powered scopes. An experienced pilot can see for miles with vision that normal people don't have. That means the the mark8eyeball was extended beyond the capability of the weapons carried. The other method was to rely on the growling of your Aim-9. At rages beyond where you should fire it, it would still make noise in your headset when pointed at another fighter. In every flight, they would have at least one F-4 with operating Radar and the rest might be the flying garbage truck. Sounds good, right?
That's what we thought. Until the end of the war games and the tally came back. Each F-15A made up 4 kills per F-4s one. Even the fact that only 33% of the F-15As could be flown. The Fact was Spang had a 95% launch rate with seasoned pilots. And Bitburg still had a 4 to one kill rate.
The F-15A last about as long as Spangs F-4s. In about a year, the F-15C were arriving (most were upgraded A) with most of the problem with the A was ironed out. And Spang started getting their brand new F-16s. Spang kept their F-4Gs for awhile until a suitable replacement F-16 was offered. What's wild the 4 to one kill rate didn't make the news back home. What did was the extreme expenses and low sortie rate of the F-15. It took years to get the F-15C and the F-16C where you see them today. So I don't see any real problems with the F-35s where time will fix everything. Remember, the F-35A has a 20 to one kill rate when you let it fight it's own fight.
