A top manager, who is referred to by Kommersant, says that the aircraft were transferred to Syria for testing aircraft weapon control systems. The first tests of weapons on the Su-57 began even before the current name was originally assigned to the T-50. Testing activities of this nature were held last summer.
It should be noted that now manufacturers are working on the creation of Su-57 aircraft with engines of the second stage. These power plants will significantly expand the capabilities of the aircraft on maneuverability and high-speed mode.
Earlier in the Defense Ministry noted that they intend to purchase 12 Su-57 under the first contract.
If Su-57 really arrived in Syria to test weapons, does this mean that in the near future they will be involved in attacking the militants of terrorist groups?
