Two more Russian fifth generation Su-57 stealth fighters have arrived at Syria's Hmeymim Airbase, Sputnik Arabic reported, referring to local media outlets.
Wael Al Hussaini tweeted that the Su-57s were escorted by Russian 4+ generation Sui-30SM multi-role fighter jets before landing at Hmeymim Airbase.
Earlier this week, Al Hussani reported about the deployment of the first two Su-57 fighters in Hmeymin, something that has yet to be confirmed by the Russian Defense Ministry.
Russian lawmaker Vladimir Gutenov told Sputnik that while he could not independently confirm the Su-57s' deployment to Syria, he "whole-heartedly welcomed" the reports.

According to him, the presence of the Su-57s will doubtlessly send a political message, serving as a deterrent "for aircraft from neighboring states which periodically fly into" Syrian airspace uninvited.
Designed for air superiority and attack roles, the Su-57 is fitted with a sophisticated avionics system capable of autonomous battlefield calculations, allowing it to assist the pilot.
Additionally, the plane is equipped with an active airborne phased array radar, which helps the Su-57 detect air, ground and naval targets at distances far beyond most modern systems.
