Russia' aerial campaign "served as a de facto live-fire operational test and evaluation period for Russia’s newest warplanes," defense expert Dave Majumdar wrote for the National Interest.
The remarks come following reports that several minor technical glitches affected the Sukhoi Su-34 Fullback and the Su-35S Flanker-E were found while they were deployed to Syria. The malfunctions in the flight control system and engines of the aircraft were said to have been "noncritical" and were promptly fixed on the spot.
The Su-34, that made its combat debut in Syria, is probably the most technologically advanced aircraft in Russia's arsenal.
Poland's TVN24 called Moscow's operation in Syria a "gigantic promotional campaign for Russian weapons."
Russian daily Kommersant recently reported that Russia could ink deals worth $6-7 billion in the years to come thanks to the anti-Daesh efforts. The campaign itself is estimated to have cost Moscow less than $480 million. On Tuesday, President Vladimir Putin announced that Russia's arms exports totaled a record $14.5 billion in 2015.
