Intro
Compare the worlds most advanced stealth fighters: the F-22 Raptor and Su-57 Felon. Discover the 5 key differences in design, capabilities, and features that set these fifth-generation jets apart. Learn about their radar-evading stealth technology, advanced avionics, and supercruise capabilities in this in-depth analysis of the F-22 vs Su-57.
The F-22 Raptor and the Su-57 Felon are two of the most advanced stealth fighters in the world, with cutting-edge technology and capabilities that make them nearly invisible to radar. While both aircraft share some similarities, there are significant differences between them. In this article, we'll explore the 5 key differences between the F-22 and the Su-57, and examine what sets these two stealth fighters apart.
Background and Development
The F-22 Raptor is a fifth-generation stealth fighter developed by Lockheed Martin for the United States Air Force. The F-22 first flew in 1997 and entered service in 2005. The Su-57 Felon, on the other hand, is a Russian fifth-generation stealth fighter developed by Sukhoi. The Su-57 first flew in 2010 and is expected to enter service with the Russian Air Force in the near future.
1. Design and Aerodynamics
Design and Aerodynamics
The F-22 has a unique design with a curved, faceted shape that helps to scatter radar waves and reduce its radar cross-section. The aircraft has a length of 62 feet 1 inch, a wingspan of 44 feet 6 inches, and a height of 16 feet 8 inches. The Su-57, on the other hand, has a more conventional design with a blended wing and fuselage. The Su-57 has a length of 69 feet 1 inch, a wingspan of 46 feet 7 inches, and a height of 17 feet 7 inches.
In terms of aerodynamics, the F-22 has a unique air intake design that helps to reduce radar reflectivity. The aircraft also has a thrust vectoring system that allows it to maneuver more effectively at high angles of attack. The Su-57, on the other hand, has a more conventional air intake design and a three-dimensional thrust vectoring system.
2. Propulsion
Propulsion
The F-22 is powered by two Pratt & Whitney F119-PW-100 engines, each producing 35,000 pounds of thrust. The engines are equipped with a thrust vectoring system that allows the aircraft to maneuver more effectively at high angles of attack. The Su-57, on the other hand, is powered by two Saturn AL-41F1S engines, each producing 14,500 pounds of thrust. The engines are also equipped with a thrust vectoring system, but it is less advanced than the F-22's system.
3. Radar and Sensors
Radar and Sensors
The F-22 has a highly advanced radar system, known as the AN/APG-77, which uses a phased array antenna to detect and track targets. The radar system has a range of over 100 miles and can detect targets as small as a bird. The Su-57, on the other hand, has a radar system known as the N036 Byelka, which uses a phased array antenna to detect and track targets. The radar system has a range of over 60 miles and can detect targets as small as a fighter jet.
4. Avionics and Electronics
Avionics and Electronics
The F-22 has a highly advanced avionics system, known as the Communications, Navigation, and Identification (CNI) system, which allows the aircraft to communicate with other aircraft and ground stations. The system also includes a advanced electronic warfare system that can detect and disrupt enemy radar and communication systems. The Su-57, on the other hand, has a less advanced avionics system, known as the Sh-121 multi-functional integrated radio electronic system, which allows the aircraft to communicate with other aircraft and ground stations.
5. Cost and Production
Cost and Production
The F-22 is one of the most expensive fighter jets in the world, with a unit cost of over $150 million. The aircraft is produced by Lockheed Martin at its plant in Marietta, Georgia. The Su-57, on the other hand, is expected to be significantly cheaper, with a unit cost of around $50 million. The aircraft is produced by Sukhoi at its plant in Komsomolsk-on-Amur, Russia.
