New Large Chinese Submarine With Very Unique Feature Just Caught On Satellite Imagery

Summary

Satellite imagery captured at China's Jiangnan Shipyard in Shanghai has revealed a new and unusually large Chinese submarine that appears to lack a traditional sail, a distinctive structural feature found on conventional submarines. The vessel, whose designation remains unknown, measures approximately 394 feet in length and 33-36 feet in width, making it larger than most nuclear-powered attack submarines currently in service, including China's own Type 093 and the U.S. Navy's Virginia-class submarines. The submarine also features an X-form rudder configuration and a possible shrouded pumpjet propulsor, both of which contribute to enhanced maneuverability, efficiency, and quieter underwater operation. The absence of a traditional sail offers significant hydrodynamic advantages, including reduced drag, improved speed, and a lower acoustic signature, though it also removes the traditional mounting points for periscopes, communication masts, snorkels, and surface navigation capabilities. This is not China's first experiment with sailless submarine design, as a smaller technology demonstrator with similar characteristics was previously built at the same shipyard back in 2018.

Key Takeaways

  • 1. The newly spotted Chinese submarine at Jiangnan Shipyard is notable for its lack of a traditional sail, making it highly unconventional compared to standard submarine designs worldwide
  • 2. At approximately 394 feet long, the vessel is larger than both China's Type 093 nuclear attack submarine and the U.S. Navy's Virginia-class submarines, suggesting significant operational capability
  • 3. The submarine incorporates an X-form rudder arrangement and a likely pumpjet propulsor, both advanced features that enhance stealth, maneuverability, and underwater performance
  • 4. Removing the sail improves streamlining and reduces acoustic signature but eliminates traditional mounting space for periscopes, communication antennas, snorkels, and surface navigation tools
  • 5. China has prior experience with sailless submarine technology, having launched a smaller experimental sailless submarine at the same shipyard in 2018, indicating this is part of a longer-term development program
