What is the latest engine for the Su-57?
The Su-57’s second-stage engine The 177S represents the second-stage engine for the Su-57 program, which is often referred to as Izdeliye 30 in Russian sources. The engine will deliver upon the supercruise and thrust-to-weight advantages promised for Russia’s fifth-generation fighter. Another concern lies in its engines. The SU-57 currently relies on upgraded fourth-generation engines, with its promised fifth-generation powerplants still uncertain. Without these engines, the fighter lacks the thrust, efficiency, and reliability expected of modern stealth aircraft.It’s low stealth features and Russia’s production limitations due to crippling Western sanctions amidst the Ukraine War. While the Su-57 has impressive front-aspect stealth, it suffers in overall stealth capabilities, particularly against ground-based radars.Arguably, the Su-57’s greatest weakness is its slow rate of production. The aircraft has been in development since the early 2000s, yet as of late 2024, only 31 units had been produced, with just 12 considered combat-ready.Russia has promoted the SU-57 as an equivalent to the US’ F-35 – which is thought to be “the world’s most advanced multirole fighter jet. It is the first sophisticated fighter plane Russia has produced since the end of the Cold War.Su-57 excels in speed, manoeuvrability, and cost-effectiveness, better-suited for air superiority and defensive roles. The F-35 is superior in stealth, sensor integration, and combat-proven reliability, making it ideal for offensive operations and networked warfare.
Is there a 6th generation fighter jet?
Boeing has started production of the first F-47 sixth-generation stealth fighter for the U. S. Air Force. The goal now is for that jet to make its first flight sometime in 2028. A Fighter the IAF Already Rejected At the time, the assessment was clear: the aircraft lacked true fifth-generation qualities. Its stealth fell well short of American benchmarks like the F-22 or F-35. It did not supercruise.Boeing has started production of the first F-47 sixth-generation stealth fighter for the U. S.
