It actually looks nothing like the F-14. The Tomcat was a swing-wing plane, which the J-15 isn’t. What the J-15 looks like (as in, 100% identical) is the Russian SU-33 naval fighter. Which is not surprising since the J-15 is a copy of that fighter.
Nothing like? I know I’m no aviator and I built my son the model of the F-14 twenty years ago, so I’ll take your word for it but in general it has twin tails, twin engines, a similar wing design (doesn’t appear to have the swing-wing capability as you stated), is a two-seater I suppose and overall length looks comparable. In reading the other comments it appears that the Russians borrowed our design (as you mentioned the Russian aircraft) and now the Chinese stole theirs. Nice to know the Chinese are equal opportunity thieves, but then, what’s a little stealing between Marxists anyway?
