On a broader scale, the US has been involved against mostly low-tech countries. Same as us (the French). Wether in Africa (Sangaris and Barkane operations) or in Afghanistan (Epidote), we have only engaged ground troops hiding in dirt houses, maybe a couple of WWII tanks. Is there such a need as the F-35 ? This would mean a symmetrical war and I doubt this would be settled though fighters, unfortunately. There seems to be some kind of distortion between the geopolitical reality vs. the wars and needs of the USAF ?
Yeah no. We have used our various fighter jets to bomb entire sections/targets of cities/countries in the ME and I am not talking about mud houses, and we have used them against ISIS, the Taliban and Al Qaeda who are embedded in the various mountain ranges, hills and in the valleys. They have also been used to destroy key buildings (again not mud huts) where ISIS has either stayed/is staying, had communications systems, munitions, weapon caches, or other substantial rewards to target. We have used our fighters to bomb heavy equipment and various combat vehicles held by the various terrorist groups as well.
In August, we sent two B-52 bombers over there, the first since I believe the Gulf war. Since Russia entered the fray, we have had to send our fighters up on several occasions now to warn the Russians and Syria not to bomb or to stop bombing where we have our Special Forces embedded (like with the Kurds in various locations), and where other coalition troops are also embedded. (the Russians are such dicks) We had B-1 bombers over there, but sent them back to the US in February or March of this year for maintenance. The AF F-15's, F-16s, F-22's fighters and drones, have flown consistently and have flown more than half of the combat missions in the ME. We've even this year, piloted by the Marines, used A-10's over there and the Navy has been using their F-18's for several years now.
The variety/diversities of missions are enumerable and the bulk of "fighting" has been from the air. At one point earlier this year, we had completed something like 5, 200 airstrikes and I haven't kept up on how many currently. The US produces like 85% of the air strikes over there. We have protected and supported the Peshmerga ground troops, various coalition fighters/troops and even the Iraqi Security Forces. Pilots and their WO's also fly missions besides targeted bombings, where they perform reconnaissance and gather intelligence on watching patterns of civilians and trying to discern what vehicles for example or buildings are occupied by terrorists. They also look for enemy troops, vehicles and weapons.
We have used our fighters to also destroy supply routes and bridges.We also use our fighters to see/monitor if terrorists are still crossing over from Turkey's borders. We also used our fighters to bomb many of ISIS's oil refineries and the lines of massive trucks that formed on the roads leading to the ISIS controlled oil fields.
I am sure that members here from the Military (current and former who have been there/done that) can certainly report on more than I can, even through I try to keep up as best as I can and they can explain the need for our fighters and the F-35, their targets and various missions.
Right now we are using our fighter jets alongside French jets, Iraqi AF jets in Mosul, our drones, along with our helicopter gunships (Apaches). The Danes have/are in the process of bailing from the ME. And the latest news ( at least that I am reading with crappy google translator in some ME newspapers) is now that ISIS has developed their own unmanned drones.
