At the same time, Chinese designers are believed to be hard at work on a fourth class of carrier, Type 004. According to Popular Science, a leak by the shipbuilder claims the new class, “will displace between ninety thousand and one hundred thousand tons and have electromagnetically assisted launch system (EMALS) catapults for getting aircrafts off the deck. It'll likely carry a large air wing of J-15 fighters, J-31 stealth fighters, KJ-600 airborne early warning and control aircraft, anti-submarine warfare helicopters, and stealth attack drones.” Such specifications will make them the equal of U.S. carriers, at least on paper.
