Kind of. For various budgetary reasons and capex vs opex and stuff like that, the US only has two aggressor squadrons now, the 18th and 64th. The 65th shut down recently. We're kinda getting out of that business.
Something quietly muttered about is we don't have the labor force anymore, so better off having our pilots in fighting squadrons instead of training squadrons.
Another topic not mentioned much is the whole concept of aggressor squadrons and Top Gun etc came from fighting similar tier adversaries in the 60s and, while not losing, not winning at a high enough ratio, and cold war REFORGER war plan against the Soviets was to use our higher tech to hold back their larger numbers. We needed each of our F-14 to shoot down at least 7 of their Mig-21 to win WWIII in 1985, or at least to not lose too quickly. None of this has really been relevant since 1990 and drone and cruise missile tech and so forth make the whole concept pointless. So political bureaucracy rules of warfare are such that if you can't shut down an obsolete program directly, you can outsource it all on a contract that coincidentally will not be renewed in 2025 or whatever year. We're just never going to see future air combat where its a war of attrition between our small number of high tech F-14 tomcats vs a larger number of mig-21s. Put the money where it'll actually be used in the future, such as drones, cruise missiles, smart bombs, fancy AA and AG missiles, etc. The idea of training F-14 pilots to do air combat maneuvering using guns and 70s performance missiles against a number of Mig-21 is VERY 1980s.
Or future adversary isn't going to send 8 Mig-21's against each of our F-14, they're going to launch 240 anti-personnel quadcopter drones toward the airfield per day to shut down operations. Sure at a thousand bucks per drone plus COTS grenade, thats a quarter mil per day to deny air operations... now is that quarter mil cheap or expensive? Compared to the damage a functioning air force base can do to an opponent, that's cheap. Or they'll build $100 cloud steerable laser pointers and deploy them randomly across the land by the thousands to lase the eyes and sensors of every vehicle in the air that's not one of theirs. They'll win that war of attrition if they deploy 10K semi-autonomous weapons that each cost $1000 and we only have 1K ATG missiles in theater which cost $100K each, either way they win.
Well, generals always like to train to win the last war, not the next one, thats been true for a couple thousand years now.
