Let's go to the detailed specifications of the two aircrafts
1.F5E tiger carries more weight thus more ordenance (bombs)
2.J 7 uses R 60m air to air missiles which only has a range of 8km maximum at mach2.7
On the other hand F 5E tiger is equiped with a wide range of air to air missiles .ie aim 9,agm 65 Maverick and python 3 .python 3 from Israel has a range of 20km + at mach 4
3.Python 3 is the same missile used by F 15 and to some extent the su 30 that means a trained F 5 pilot can easily kill an SU 30 in a dog fight.
4.J 7 only has short range attacking capabilities in dog fights not compareble to F 5E tiger
5.J7 cockpit design is very poor and this makes the pilot to have limited visibility making it susceptible to being short by other jets and missiles without even using counter measures.
6.The only advantage J 7 has it's that it can strike and run away very fast but still F 5E
missiles can outrun it.
7.according to your earlier claims that F5E doesnot carry guided munations .AIM 9 are heat seeking air to air missiles,.Agm 65 marverick has the following guidance systems
Electro-optical guidancei,infraredguidance,
Laser guidance.AGM 65 is air to ground missile.F 5E can also carry unguided bombs.
8.You also claimed that no country is using F 5E fighter,US navy are still using it and it's not retiring soon, Netherlands, Philippines,and Canada are among the users of the jet
9.J7 has a combat radius of 2500km while F 5 tiger has a combat radius of 1543mile=2338.88km a difference of 200km.
10.I can back up my claims with evidence if need be.
