YES. NEXT QUESTION? Is Russia’s Su-57 the worst stealth fighter on the planet? “It’s not just with stealth and propulsion that the Su-57 continues to lag behind the competition. One of the aircraft’s selling points has also been its sensor suite and advanced avionics — with the Russian government claiming the fighter is capable of full 360-degree sensor coverage much like the flying supercomputer F-35 Joint Strike Fighter. To date, it does not appear that any such system is online in the Su-57, with the Rand Corporation analysis positing that sanctions placed on Russia after its military annexation of Crimean in 2014 have further hindered the system’s development.”
