China Unveils Second Massive UUV Mothership in Guangzhou

Key points

• Social media videos show a new naval auxiliary vessel being towed on the Pearl River in Guangzhou, near the Panyu district.
• The ship is suspected to be a UUV mothership, designed to launch and recover very large underwater drones.
• The vessel is approximately 150 meters long, making it smaller than a similar 200-meter ship under construction in Shanghai.
• The Guangzhou ship features six lifting masts at the stern, compared to twelve on the Shanghai unit.
• The ship is likely being built at the COMEC shipyard in Huangpu, which also constructs amphibious barges and replenishment ships for the Chinese Navy.

Background

In October 2026, Naval News reported on a new type of presumed Chinese UUV mothership under construction in Shanghai. This earlier report noted that the Shanghai vessel was slightly over 200 meters long and had twelve lifting masts. The current development in Guangzhou represents a second, distinct design for this class of vessel.

Why it matters

The appearance of a second UUV mothership indicates that China is actively expanding its fleet of large, specialized naval auxiliaries. These vessels are crucial for deploying and recovering massive underwater drones, which could significantly enhance China's naval capabilities and strategic reach in the Indo-Pacific region.

What to watch

Further imagery and official announcements from China are needed to confirm the exact purpose and specifications of the new vessel. Analysts will continue to monitor the ship's progress and any related developments in Chinese naval construction.
