Re: No F-22B version

The answer to all your questions is money. Building them and operating them was super expensive, and the F-35 was to be *much* cheaper.

Re: An upgraded F-35 in 10 years

No. The J-10 (First flight 1998) is in no way a copy of the Saab Viggen (First flight 1967). They both have delta wings and canards, but so does every fighter made in Europe in the last 20 years (and they are not copies of the Viggen either). That combination is just one of the standard solutions t...

Re: Future of the Turkish Air Force

I think the long term future for the Turkish Air Force involves repairing relations with the U.S. after Edrogan is gone and re-entering the F-35 program. And they need to swallow their pride and scrap the stealth fighter program that is going to suck up tremendous amounts of money and resources. Bu...
