Russia’s brand new Su-35S multirole fighters will go through the baptism by fire in Syria, according to a military source.

Russia is preparing to test the next-generation Su-35S fighters for the first time in combat in Syria.

“The General Staff has decided to run a field test of the brand-new Su-35S in Syria for the first time ever,” the Kommersant newspaper cited its source as saying.

According to information obtained by the outlet, the first four jets were handed over to the Russian Aerospace Forces last fall. Several days ago, they were transported through Iran and Iraq to the Russian airbase in Hmeymim near Latakia in northwestern Syria.
