Russia has begun testing its new Su-57 stealth fighter engine but there's a snag
Russia's Su-57 stealth fighter made its maiden flight with its new Izdelie-30 engine last week, according to Russian media.
But there's a problem: The engines won't be ready to be used until 2025, and the Su-57 won't be ready for serial production until 2027,
