China’s 120‑Meter Sailless Submarine Spotted at Shanghai Shipyard

Overview

• Independent satellite imagery from early June 2026 shows a previously unreported roughly 120‑meter submarine moored at Jiangnan Shipyard in Shanghai and analysts report a possible second hull at Huludao.
• The boat has a very low or absent sail, a narrow beam, X‑form stern control surfaces, and what open‑source analysts say may be a shrouded pump‑jet, features aimed at cutting drag and acoustic signature.
• Experts judge the design unlikely to be a ballistic‑missile submarine and say conventional nuclear propulsion is the most probable option while noting a nuclear‑AIP concept has been discussed as an alternative.
• Observers warn the size and form could support long endurance seabed tasks and raise new risks to undersea infrastructure such as fiber‑optic cables that carry most regional internet traffic.
• The discovery adds to China’s rapid build‑up—about 15–20 submarines across multiple new classes in five years—and if parallel production at Jiangnan and Huludao is confirmed it would mark a notable industrial scaling; Beijing has issued no public comment and analysts continue to scrutinize imagery and open sources.
