By 2007 the International Institute for Strategic Studies assessed the force as 8,000 strong with 41 combat capable aircraft and a further 188 stored. DAAFAR is known now to have integrated another MiG-29 and a few MiG-23s which makes it 58 combat aircraft in active service which are listed as 6 MiG-29s, 40 MiG-23s, and 12 MiG-21s. There were also assessed to be 12 operational transport aircraft plus trainers which include 8 L-39C and helicopters which are mainly Mil Mi-8, Mil Mi-17 and Mil Mi-24 Hind. Raúl Castro ordered in 2010 that all MiG-29 pilots had to have full training, they now have from 200–250 hours of flight annually together with real dogfight training and exercises. Up to 20 MiG-23 units also have this kind of training but the other 16 MiG-23 units spend more time in simulators than real flight. MiG-21 units have limited time in these training exercises and spend more time in simulators and maintain their skills flying with the commercial brand of the air force Aerogaviota.
