How are Chinese aircraft, tanks, and missiles numbered? What is the F15? What naming principles are followed?

Aircraft: J starts with fighter, F starts with fighter, B means bomber, FB means fighter-bomber, Z means helicopter

Tank: T starts with main battle tank, but among us They usually call them Type 85, Type 85, Type 99, etc.

You have to look at the type of missiles~ ground-air-ground-ship, air-air, air-ship, there are too many of them~~
