Satellite Images Reveal 120-Meter Chinese Submarine Without a Sail
2 articles · Updated · Мілітарний · Jun 2
Summary
May 31-June 1 satellite images show a previously unknown Chinese submarine moored by a barge outside Shanghai’s Jiangnan shipyard, with no traditional sail visible above the waterline.
Naval analysts say the boat’s streamlined bow, X-shaped stern and very low profile point to a new class designed to cut hydrodynamic drag, though its mission and propulsion remain unconfirmed.
At roughly 120 meters long and 10-11 meters wide, it appears longer but narrower than another recently launched submarine in Bohai and is considered too small for a JL-3-armed ballistic-missile role.
Its size makes nuclear propulsion the leading estimate; if conventionally powered, it could be the world’s largest non-nuclear submarine. China has also been developing compact reactor systems akin to high-endurance AIP.
The sighting adds to evidence of rapid Chinese undersea expansion, with separate imagery around the same time suggesting another submarine launch at Huludao, a yard focused on nuclear boats.

Overview
In late May 2026, a groundbreaking Chinese submarine design was discovered at the Jiangnan Shipyard, marking a major leap in naval engineering. This new vessel stands out for its low-profile, sail-less design, which eliminates the traditional sail that usually creates hydrodynamic drag and increases a submarine’s acoustic and radar signature. By removing the sail, the submarine achieves a streamlined form, aiming for unprecedented stealth and speed underwater. This innovation points to a future where stealth and speed are crucial in underwater warfare, highlighting China’s ambition to redefine submarine capabilities and naval power.
