India’s Ministry of Defense (MoD) recently unveiled that it has launched the earlier stage of development for its unmanned underwater vehicle (UUV) program as part of its ongoing military modernization efforts.

In recent years, New Delhi has been cranking up its efforts to maximize the capacity of its armed forces, including procuring advanced equipment and armaments for its Navy. According to Naval News, the Indian Navy is looking to acquire at least 12 Extra Large UUVs (XLUUVs) as soon as prototypes are approved and clear all necessary trials by 2025, citing a document released by the MoD.

The MoD document also discussed some of the expected details of the future Indian XLUUVs, including the prototype platforms measurements: 50 meters (164 feet) long, five m (16 ft) wide, and 10 m (33 ft) high, with an estimated gross weight of no more than 300 tons (300,000 kilograms). However, these specifications are still subject to change as the development progresses.

The Indian XLUUV, though still in the early stage of the project, is anticipated to join the Modifiable Underwater Mothership of Germany, the Orca XLUUV of the US Navy, and the Sarma-D of Russia as one of the most enormous submarine drones ever created. Additionally, China is actively working on multiple XLUUV projects and will likely join the rest of the superpowers in fielding the future UUV platform.
