The J-15 Fighter in One Word: Heavy – The Shenyang J-15 “Flying Shark” is among the heaviest fighters ever flown from the deck of a ship, and every argument anyone has had about this aircraft for twelve years traces back to that one fact.
The J-15: Explained
The weight is inherited. The J-15 was reverse-engineered from an unfinished Su-33 prototype that China acquired from Ukraine in the early 2000s, and the Su-33 is the naval branch of the Sukhoi Flanker, a big, long-ranged, twin-engine air-superiority design that was never small to begin with.
