Su-35 Sukhoi
Su-35
ASCC codename: Flanker
Multi-Role Fighter

DESCRIPTION:
The original Su-35 was a derivative of the Su-27 and essentially a ground-based variant of the Su-33. While the official Russian Air Force designation for the aircraft remained the Su-27M, Sukhoi rechristened the model as the Su-35 in the hopes of attracting foreign customers.

The Su-35 design was largely identical to the Su-27 but incorporated the canards of the Su-33 and more powerful engines plus a new digital fly-by-wire control system. The Su-35 was also equipped with a new multi-mode radar, infrared detectors, and upgraded weapons. The Su-35 development program experienced many delays due to the collapse of the Soviet economy, and the Russian military ultimately chose not to purchase any. Sukhoi instead used the eleven prototypes as technology demonstrators to interest the export market in funding a production model.

The most likely chance for success appeared to be Brazil's strong interest in co-producing the Su-35 that lasted for several years. Brazil required a replacement for its aging Mirage III fighters, and the Su-35 was considered the front-runner over the competing Mirage 2000, Gripen, and F-16. The Su-35 deal came close to being finalized in November 2004, but Brazil declined to sign over cost concerns. Russia later offered second-hand Su-27 aircraft as a cheaper alternative to the new-build Su-35, but Brazil opted to purchase twelve refurbished Mirage 2000 fighters from France instead.

The Brazilian decision appeared to have ended the Su-35 program once and for all since Sukhoi had little success finding other customers. Hopes were briefly revived in May 2006 when Venezuela announced interest in the Su-35, but the nation instead chose a variant of the Su-30.

However, the Su-35 was revived, at least in name, in 2007 when Sukhoi announced the aircraft had entered production for the Russian Air Force. This incarnation is also a derivative of the Su-27 but is not directly related to the earlier Su-27M/Su-35 prototypes. The new Su-35, called the Su-35BM by Sukhoi, is instead an upgraded variant of the Su-30. This variant is most similar to the Su-30MKI model built for India and features a more powerful engine, an improved 2D thrust vectoring nozzle, and larger air intakes. The Su-35BM lacks the canards of the original Su-35 prototypes, although some sources indicate these can be fitted at customer request. Other upgrades include an improved radar, glass cockpit displays, compatibility with additional weapons, structural strengthening to increase service life, and incorporation of newer electronics.

A production model known as the Su-35S has entered acceptance testing, and 48 have been ordered by the Russian Air Force. An Su-35K export model has also been marketed to Algeria, Libya, China, India, Malaysia, and Brazil. Venezuela has placed an order for 24.
