CSIS sees China's first nuclear carrier launching by late 2027

Satellite imagery of China's Dalian shipyard shows the hull of a fourth aircraft carrier, assessed by CSIS as likely nuclear powered and possibly the Type 004, measuring about 322 metres long and 46 metres wide less than two years after its first prefabricated sections appeared.

Why it matters: A nuclear powered carrier would give China sustained high speed operations far from home waters without refuelling for propulsion, a capability so far held only by the United States and France, and the pace of construction underlines the speed of China's naval buildout.

Data as of CSIS satellite assessment of the Dalian shipyard hull, as reported by Marine Insight on October 31, 2026 and Interesting Engineering on October 30, 2026, each read in full. CSIS assesses nuclear propulsion as likely, citing hull compartments resembling shielded reactor spaces; Beijing has not confirmed the ship's designation, propulsion or a launch date, and the late 2027 launch timing is an inference from the construction pace, not an official schedule.

An updated CSIS assessment of satellite imagery from China’s Dalian shipyard puts the unfinished hull of a fourth Chinese aircraft carrier at about 322 metres long and 46 metres wide, larger than the Fujian at a comparable stage, less than two years after prefabricated hull sections first appeared in the dry dock in early 2025. CSIS assesses that the ship, widely called the Type 004, is likely nuclear powered, based in part on two large compartments resembling shielded reactor spaces, and that it could carry as many as four aircraft launch catapults. On the construction pace CSIS has documented, a launch by the end of 2027 is possible, though Beijing has confirmed neither the propulsion nor any schedule.
