The arrival of the Su-34 'Fullback' fighter bomber to Syria could be seen as imminent since the initial deployment of the first combat assets to Syria, and has now finally confirmed to have occurred in recent days. Up to six Su-34s are now believed to have joined the four Su-30SMs, twelve Su-24M(2)s and twelve Su-25s already present at Hmeemeem/Bassel al-Assad IAP, Lattakia Governorate.

After the sighting of Su-30MS' and Su-24M2s over Syrian airspace just days ago, new satellite imagery acquired by Stratfor and AllSource Analysis dating from the 20th of September has now revealed the presence of twelve Su-25 'Frogfoots' being assembled at Hmeemeem/Bassel al-Assad IAP for a total of twenty Russian combat aircraft now confirmed to be deployed in Syria. Around the same time, U.S. officials claimed that no less than twenty-eight combat aircraft and up to twenty helicopters have now been stationed in Syria as part of wider Russian deployment of military personnel in Syria.

Amid a range of reports of sightings of Russian military personnel and equipment used in combat in Syria, Russia's role in the conflict escalated sharply with the confirmation of Russian aircraft and armoured vehicles being flown in by the dozens. Coinciding with the renovation of Hmeemeem/Bassel al-Assad IAP for use as a Russian military base, Il-76 strategic airlifters or (more likely) Il-78 aerial refuelling planes have been sighted escorting military aircraft such as the Su-30SM and Su-24M(2) over Syria, together with An-124 strategic airlifters reportedly carrying at least two Mi-17 and two Mi-24/35 helicopters amongst a range of other weaponry.
