Russian Air Force Su-35S RF-81745 with bort 57 red is seen here during MAKS 2017 at Zhukovsky. This is the second use of the designation Su-35. The first use was also known as the Su-27M and the first flew in June 1988. It failed to attract orders. In February 2008, the first flight took place of the second Su-35 model, this version incorporates technology from the PAK FA program and has a redesigned cockpit and weapons-control system and features thrust-vectoring engines in place of the canards. Although it was designed for export, the Russian Air Force became the launch customer in 2009.
