So far, around 1425 x MiG-29s of all types have been produced for 21 air forces around the world and you have to add that MiG-29 engines power aircraft in 22 air forces remembering that South Africa has installed the RD-33 into the their F-1s as an upgrade. This entire fleet of MiG-29s have not as yet reached one million flight hours and they are sharing an accident rate of around 10 losses per 100,000 flight hours, the F-16 is 2.4 right now, or 4 times better and the F/A-18 is holding over 7.5.
