Sukhoi T-50 (aka Pak Fa) tested with an Il-78 Tanker for Air Refueling

Although this is an authomatic translation from Russian to English, it can be clearly understand. Original text in Russian

Company "Sukhoi" conducted experiments on the approach and docking of the PAK FA (T-50) with a fuel tanker. Contacting, nine in a single flight. In addition to testing the T-50-2 was involved tanker IL-78 with a crew of marching military units and aircraft maintenance Su25UB with a crew of Air Force test center.

The T-50-2, there are studies on the stability, handling and strength of the aircraft in a range of subsonic and supersonic flight regimes in various configurations.

The first flight model of the T-50-1 completes the program of preparation for the test flight at high angles of attack and supercritical maneuverability.

The T-50-3 in August began flight testing with a unique on-board radar with active electronically scanned array (AESA radar with) in the on-board avionics. During ground and flight tests on the prototype T-50-3 when checking modes radar "air-to-air" and "air-surface" in the first experiments produced a significant and sustainable impact on the level of the best existing features of the aircraft. Confirmed by the further development of these capabilities. The works on the evaluation of the optical channels.

Designed Institute of Instrument. Tikhomirov's AESA can increase detection range, parallel work in the "air-to-air" and "air-to-surface" to recognize and classify the group and single objects simultaneously attack multiple targets with precision weapons, and to provide communication and electronic countermeasures.

This year, the test program will join the fourth prototype of the PAK FA.
