The fact of the matter is that USN operates nearly 1100 Fighters, while as you said, Marine corp has another 350 FightersMate,i think that you have made a slight mistake here.The U.S.N. doesn't operate Harrier AV-8B aircraft.They are part of the Marina Aviation.The U.S.N. inventory includes 570 F/A-18 E/F Super Hornets,114 EA 18G Growler and around 380 F/A-18 C/D Hornets.The Marine aviation includes around 125 Harrier II AV-8B and aorund 225 F/A-18 A/B/C/D Hornets.
PLAAF has only 580 4th Gen fighters, IAF has barely 300
So my point still stands,
