What is the difference between aim-120d and 260? If the size is the same, how can it achieve more range? Can pla use the same tech to make pl-15 even more long range since pl-15 is a bigger missile?
JATM is a modernized improvement along the same path, which isn't using a 34 year-old form factor. It gets more range thanks to advances in metallurgy, propellant, materials science, etc. And of course everyone can use the same physics; how do you think PL-16 is both smaller and better than PL-15?
