القوات الجوية العربية السورية
At the beginning of August 2015, a summary of the recent Syrian Air Force activity reported that during July 2015, the Syrian Air Force performed 6,673 air attacks, the highest number since the beginning of the war. It was reported that between October 2014 and July 2015, at least 26,517 attacks were made. This showed that aircraft losses had been overestimated, while the airframe overhauling and rotation increased the overall combat readiness of the Syrian Air Force since Syria could not count on replacements, apart from some refurbished ex-Iraqi Su-22s, delivered from Iran in the Spring of 2015, which had been flown there during the Gulf War in 1991. In early 2015, it was rumored that Russian pilots were flying operations for the Syrian Air Force.
