Satellite imagery captured at a shipyard in Shanghai has revealed a new large Chinese submarine with an unusual feature: the apparent absence of the traditional conning tower, commonly known as the “sail.”
According to a report from The War Zone, the vessel was observed at the Jiangnan Shipyard and quickly drew the attention of defense analysts and undersea warfare experts.
Initial assessments suggest that the submarine measures approximately 120 meters in length and between 10 and 11 meters in width, making it larger than most conventional submarines and comparable in size to many nuclear-powered attack submarines. Its designation and mission remain unknown.
Experts believe the sail-less design could offer significant advantages, including a reduced acoustic signature, improved hydrodynamics, and higher submerged speed. The configuration could also enhance maneuverability and make detection by enemy sensors more difficult. On the other hand, the absence of the traditional structure raises challenges related to the installation of masts, sensors, periscopes, and communication systems.
This is not the first sighting of its kind. In 2018, the same shipyard launched a smaller experimental submarine with a similar profile, suggesting that China has been studying this concept for several years. More recently, Chinese state-owned companies have also unveiled concepts for unmanned underwater vehicles with comparable shapes.
Analysts speculate that the new vessel may be linked to rapid interception missions, stealth technology testing, or the development of a future class of high-performance submarines. So far, however, Beijing has not released any official information about the project.
The appearance of the submarine comes amid the rapid modernization of China’s submarine fleet, which in recent years has introduced new classes of nuclear and conventional submarines while investing heavily in technologies aimed at reducing noise and improving combat survivability.
