The introduction of the Su-35S into the service with the Russian Air Force is a part of the Russia's state armament programme for 2011–2020 that was formulated following the war with Georgia in 2008 with an aim to significantly increase the number of modern military equipment in the Russian Armed Forces. The aircraft is delivered alongside the Su-30M2 and Su-30SM and the heavier Su-34 strike aircraft. The first two are domestic variants of KnAAPO's Su-30MK2 and Irkut's Su-30MKI two-seat export aircraft. According to reports, the simultaneous acquisition of three fighter derivatives of the original Su-27 was to support the two aircraft manufacturers amidst a slump in export orders. The Su-30M2 serves as a trainer aircraft for the Su-35.
