Wont it make the jet a big, fat, slow ,overweight, underpowered, bigger blip on radar.. ?
I dont think even ws-13 would be able to support that kind of a burden. (Combined with AESA chin POD & other stuff) . . U are talking about an engine with bigger dimensions. . Bigger engine means major changes in air frame. Means bigger belly , means bigger over all jet dimensions, means more room for fuel&pods ... & if we are going to make so many changes, why shouldnt we just call it JF-27
..
Or we can use ws-10 (used in j10b) in dual seater thunder and keep it as an option for an upgrade
