I was bored and decided to estimate airforces strength. I wrote down the list of active aircrafts for each air force and then counted score.
Here is method I used. F-16C I used as base: 1 air-air point/1 air to ground point. For other aircrafts my estimates are follow:
F-16C = 1/1
F-16A = 0.8/0.8
F-16 block 52+ aka F-16I = 1.1/1.2
F-16 block 60 = 1.3/1.2
F-15A = 1.2/0.5
F-15C = 1.3/0.5
F-15E = 1.4/1.5
F-15S = 1.3/1.4
F-15SG = 1.5/1.5
F-18A = 1/1.1
F-18F = 1.3/1.3
F-2 = 1.3/1.2
F-16AM = 1/08
Mirage 2000 = 1/1
Typhoon (MESA radar) = 1.3/1.1
Rafale (PESA radar) = 1.2/1.2
Tornado IDS = 0.5/1.2
Tornado ADV = 1/0.6
F-4 = 0.4/0.7
F-4 Terminator = 0.6/1
Su-27 = 1.2/0.4
MiG-29 = 0.9/0.5
Su-30MKI = 1.3/1.2
Su-30MKK = 1.2/1.2
MiG-21 aka J7 = 0.3/0.4
MiG-27 = 0.3/0.7
JF-17 = 0.9/0.8
AMX = 0.3/0.5
Mirage F.1 = 0.7/0.8
Mirage 3/5 = 0.3/0.4
Jaguar = 0.2/0.6
F-5 = 0.3/0.4
J-10 = 1/1
J-8 = 0.6/0.4
JH-7 = 0.5/1.1
Q-5 = 0.1/0.4
H-6 = 0/1
E-3, Phalcon, KJ-2000, Boeing 737 = 8/0
Saab, KJ-200 = 6/0
E-2C, ZDK-03 = 4/0
jet tanker = 2/6
KC-130, H-6 tankers = 1/4
