The opposite of the "design by committee" method that resulted in the F-35 disaster. A plane so bad in every imaginable way it was put (and kept) in production purely and reluctantly as a jobs program.
Well when they request 5-6 variants and one is very different, things happen. Idk if it’s as bad as the Bradley fighting vehicle in production.
There was one huge order over many years that cause the continuous production. This doesn’t include variants sold to several other nations.
For the I series: “A senior IAF official said that the F-35's stealth may be partly overcome within 10 years despite a 30 to 40-year service life, thus Israel's insistence on using their own electronic warfare systems”.
