Flightglobal forteller at flyet heter SU75:
Quote:
UAC chief executive Yuri Slyusar told those assembled that the single-engined jet – which had been earlier revealed as “Project Checkmate” – was “more than just a mock-up”. Instead, it is understood to be an engineering prototype for ground testing, including iron bird and copper bird functions.
Although Slyusar did refer to the design as the Su-75, the right to confer designations traditionally belongs to Russia’s armed forces, once the aircraft is operational. He notes that the name is a deliberate reverse of the digits on Sukhoi’s twin-engined Su-57 stealth fighter, developed for the Russian air force.
