Su-27 (Russia): Entered into the Soviet Union’s air force in 1985, the Sukhoi Su-27 is still one of the most successful fighters in history. Despite a relatively high age, but the combat ability of the Su-27 is still extremely scary. It can reach speeds of Mach 2.35 (800 m / s) and carries eight air-to-air missiles and a huge bomb mass. In particular, the Su-27 is known for its maneuverability in narrow ranges, performing difficult acrobatic flying techniques such as the “Pugachev cobra”, or even shutting off the engine suddenly while in a dive. The Vietnam Air Force currently owns 12 Su-27s, along with 36 Su-30MK2s, which are upgraded versions of the Su-27.
Su-57 (Russia): Sukhoi PAK FA T-50 also known as Su-57 is the fifth generation fighter aircraft of the Russian Air Force. It promises to help Russia maintain control of the sky in the next half century. Last month, Russia brought the Su-57 to Syria for testing. Su-57 is built with many components using compostie materials to strengthen the body structure but ensure light, maneuverability, increase stealth and carry many modern weapons.
