The Ash Sha’irat airbase, located to the southeast of Homs, which was struck by the Tomahawk cruise missiles of the US Navy, is one of the main bases of the Syrian Air Force. The forces of the 50th Air Brigade, in particular the 677th and 685th squadrons on the Su-22M3/M4 fighter bombers and the 675th squadron on the MiG-23ML/MLD fighter jets, were based there.
Taking into account losses for previous years, probably, there could be about one and a half dozen of the combat-ready Su-22s at the airbase at the moment of the missile strike. As for the MiG-23ML/MLD, it seems that the most part of the combat-ready aircraft have been redeployed to Hama in recent years, though, there should still have been several more flightworthy fighter jets of this model on the Ash Sha’irat airbase.
In addition, some part of the Su-22, Su-24 and L-39 aircraft from the T4 airbase was based on the Ash Sha’irat airbase for some time, when terrorists of the Islamic State (IS) group approached it closely. Some of these fighter jets, as well as helicopters of the Russian Aerospace Forces, which also used this base from time to time, still can be seen on satellite images, dated by January and February of this year. But now they should have already returned to the T4, after terrorists were thrown out of the base and Palmira was liberated again.
