4. Sukhoi Su-35
In service: 2014
Speed: Mach 2.25
Intended as a fighter that will bridge the gap between classic 4th generation fighters like Su-27 and Su-30 and the 5th generation aircraft like T-50, Su-35 that ranks 4th on the list of fastest, most advanced Russian fighter jets is usually labeled as the 4++ generation fighter. Even though it bears many similarities with its venerable predecessor Su-27, there are enough differences that it deserves its own entry. The first fighter jet bearing the Su-35 designation was designed in the 1980s. Due to the collapse of the Soviet Union, the project was abandoned. In 2003, a new Su-35 entered the design phase. It entered service with the Russian Air Force in 2014.
