General Atomics Scales Underwater Glider Program
The company plans to grow its 6.7-metre underwater glider into an extra-large unmanned submarine of up to 41 metres.
Updated on Nov. 10, 2026 in Quantum Computing
General Atomics outlined its unmanned underwater vehicle programme, centred on large underwater gliders that have completed submerged tests lasting up to 70 days. The company plans to scale its existing 6.7-metre glider into an extra-large UUV measuring 30 to 41 metres.
Why it matters
The programme points toward long-endurance undersea systems that could carry out missions currently assigned to nuclear-powered attack submarines. It is also linked to the US Navy's planned hedge force of autonomous systems.
The existing 6.7-metre vehicle is classed as a large displacement UUV with endurance of weeks to months, and submerged tests have run up to 70 days. The planned extra-large version would host between 16 and 96 smaller UUVs depending on variant size, but the timeline for that scale-up has not been specified.
The players
General Atomics
A San Diego-based defense contractor known for developing unmanned aircraft and autonomous systems for military customers.
The details
The gliders use buoyancy-driven propulsion instead of propellers, supplemented by thrusters and control surfaces, with a blended-wing design that increases internal payload volume. Listed payloads include surveillance equipment, acoustic and quantum sensors, mine deployment systems and strike packages, with concept graphics showing launch points at Okinawa and Guam.

The Tech Race
The General Atomics glider family is positioned against the US Navy's planned hedge force of autonomous systems, as the company links its extra-large vehicle concept to that effort. The programme's ambitions to match missions now performed by nuclear-powered attack submarines place it within the broader competition to replace crewed undersea platforms with autonomous ones.
The story describes defense and military undersea systems rather than products available to consumers or developers. Its practical effect on the public is limited to the extent that autonomous undersea capabilities shape future naval operations.
The takeaway
Autonomous undersea vehicles are moving toward longer endurance and larger payloads, which could change how navies conduct surveillance and strike missions. Readers following defense technology should watch whether these concepts move from company outlines into funded programmes.
