If the Russian military really relocated two fifth-generation fighter aircraft Su-57 (T-50, PAK FA) to the airbase Khemeymim in Syria, this has no practical sense.

This opinion was expressed by the air expert, the former designer of the Sukhoi Design Bureau Vadim Lukashevich in the commentary of the NSN.

For this type of aircraft, Syria is not a test. I do not quite understand why he is needed there. This is an air fighter. Our group in Syria performs tasks on land. This is the work of bombers, stormtroopers. The fighters cover them, but now there is no one to cover, because our opponents do not have aviation, and we do not enter into an open air battle with the United States and Israel, "he said..

The aviation expert noted that the air base of Khmeimim does not differ from other bases on the territory of the Russian Federation.

"It can be some kind of climatic test, but in Astrakhan in summer conditions are more abrupt than Syrian. Therefore, climatic conditions are unlikely to pass. Military tests can be conducted here. You can fly, too, with us. Participation in hostilities will not be accepted by the machine. This is very clear, "he stressed..

Lukashevich added that it makes sense to test the aircraft in combat conditions, and the Soviet Union conducted the final stage of the Su-25 attack test in Afghanistan.

"At that time it was a very secret machine. It was accompanied by a whole group of civil engineers. They also had to be protected. But there was a ground-attack aircraft that worked on the ground. It was rational: he shot everything that is possible, by polygons, and it was necessary to understand how he would work on realistic goals and perceive the specific conditions of the highlands. In Syria, this is not ", - summed up the expert.

On February 22, Russian media reported referring to sources of the transfer of two Su-57s to Syria. One source said that the aircraft is being tested and, possibly, in Syria will check its weapons.

Syrian activists reported that together with the Su-57, four Su-35 fighters and an A-50 long-range radar surveillance aircraft arrived at the Russian airbase in Syria.

Su-57 - Russian multi-purpose fighter of the fifth generation, developed by the Sukhoi Design Bureau. His first flight took place on January 29, 2010 in Komsomolsk-on-Amur. In February 2017, Deputy Defense Minister Yury Borisov announced the start of the pilot-combat operation of the Su-57.

The military conflict in Syria continues from 2011. In the fighting, government forces, oppositionists, radical Islamists, Kurds and other forces. Part of Syria is controlled by IGIL militants. In September 2015, Russia joined the conflict, which supports the Syrian President Bashar Assad. In December 2017, Russian Defense Minister Sergei Shoigu told Russian President Vladimir Putin that his order for the withdrawal of a group of Russian troops from Syria was fulfilled.
