Russia’s official designation of the
Russia’s official designation of the PAK-FA/T-50 jet as the Sukhoi Su-57 is just another reminder that the field of fifth generation fighters is about to get more crowded. The United States, China, Russia, Japan and Korea are all working on their own fifth generation designs, but so far only three planes, the F-22 Raptor, F-35 Joint Strike Fighter and the Chinese J-20 are operational. Increased tensions between the United States and NATO on one side and Russia on the other have people wondering: once the Su-57 does become operational, how will it stack up against the F-22 Raptor?
Much less is known about the Sukhoi Su-57. Despite seven years of test flights, many details about the aircraft remain unknown. What is known is that Sukhoi has struggled to develop the aircraft, particularly key components such as the engine. The first operational aircraft are slated to join the Russian Aerospace Forces in 2019.
Although both are fifth generation fighters, the Su-57 significantly differs in design philosophy from the F-22 Raptor. In the key areas of speed, maneuverability and stealth, the Raptor emphasized maneuverability and stealth. The Su-57, on the other hand, places an emphasis on maneuverability and speed, arguably making it similar to the YF-23 Black Widow II.
Experts believe the Su-57 is an evolution of the Su-27 Flanker’s shape, modernized for low radar observability but also even greater maneuverability. Aviation author Piotr Butowski claims that aircraft’s high static instability has “much more maneuverability at supersonic speeds than any previous fighter.” The blended wing design increases internal volume for avionics, fuel and weapons.
A major driver of the Su-57’s performance are its two engines. The Saturn izdeliye 30 engines are each meant to generate between 24,054 and 35,556 pounds of thrust, with the high end in the same territory as the F-22’s F119 engines. These are meant to drive the fighter to speeds of up to Mach 1.5 in supercruise. Unfortunately the izdeliye 30 is undergoing difficulties, and as a result the first twelve of Moscow’s new jets will be powered by a pair of Saturn AL-41F1 afterburning turbofans producing a combined 65,000 pounds of thrust, the same engines that power the Su-35.
The Su-57 will equip with the N056 Byelka (“squirrel”) radar system and the L402 electronic countermeasures suite. L-band arrays will be the fighter’s primary means of detecting stealth aircraft, while at shorter ranges the 101KS Atoll electro-optical suite, including an infrared search and track system, will help the pilot track and engage targets with infrared guided missiles.
The Su-57 has two large internal weapons bays arranged in tandem, taking up virtually the entire useable length of the aircraft. Each bay can carry up to four K-77M beyond visual range radar-guided missiles. Compared to earlier versions of the K-77 (NATO nickname: AA-12 Archer) the K-77M missile has a larger body and active electronically-scanned array radar seeker, allowing it to engage highly agile targets at ranges of up to 100 miles. The aircraft also stores a pair of K-74M2 short-range infrared guided missiles in underwing fairings.
The F-22 Raptor, on the other hand, emphasizes stealth and maneuverability. The F-22 can also detect adversaries at long ranges, and provided it can evade enemy radar can act to set up an ambush before the enemy knows it is in the area. Thus the F-22 has more of a likelihood of gaining the initiative early on and winning the battle before the two jets can come within visual range of one another. Key to the Raptor’s strategy, the F-22’s stealth must protect it from the prying eyes of Russian radars. In a dogfight it’s difficult to know who would prevail, given we don’t know how maneuverable the Su-57 is, but the Russian jet’s infrared search and track system—something the American stealth fighter doesn’t have—will be a major bonus in combat.
An Okhotnik demonstrator took off from a military test site for its first-ever flight on Aug. 3, 2019. The flying-wing-shape drone flew for more than 20 minutes at a maximum altitude or around 2,000 feet, reported TASS, a state news organization.
With its approximately 50-feet wingspan, Hunter-B is in the same class as China's Tian Ying drone, the U.S. Air Force's RQ-170 surveillance unmanned aerial vehicle, the U.S. Navy's experimental X-47B UAV and Boeing's X-45C drone demonstrator
