Overview
Autonomous underwater vehicles (AUVs) and unmanned underwater vehicles (UUVs) have been a DoD procurement category for decades, but the sector is experiencing a step-change in capability ambition and investment. The shift is from small, single-mission sensor vehicles (mine countermeasures, seafloor mapping) toward Extra-Large UUVs (XLUUVs) capable of autonomous 1,000+ nautical mile missions, torpedo-class undersea munitions, and submarine-launched autonomous systems.
Three developments are driving the acceleration: (1) the Ghost Shark/XLUUV program demonstrating that a defense startup can develop a large AUV from scratch for ~$100M in three years, (2) L3Harris validating torpedo-tube-launched AUV capability for covert submarine operations, and (3) Anduril’s Copperhead family establishing the concept of an autonomous undersea munition that is recoverable and reusable — unlike a torpedo.
The market is split between established defense primes (Lockheed Martin, L3Harris, Northrop Grumman, Boeing Orca) operating on long-cycle Navy programs, and a small number of startups (Anduril) with faster development cycles and software-defined architectures.
Key Themes
- Extra-Large UUV (XLUUV) as the category defining the next decade — autonomous undersea vehicles with 1,000+ nm range operating independent of a nearby mothership
- Torpedo-tube launch and recovery (TTLR) enabling submarine-launched covert AUV operations without surfacing
- Autonomous undersea munitions (Anduril Copperhead) as recoverable alternatives to expendable torpedoes
- Hull-attachment transit (Lockheed Lamprey) as a range-extension mechanism — hitchhiking on ships to arrive with full batteries
- Modular payload architecture across all new programs; ISO-container-compatible for surface vessels; swappable sections for AUVs
- Additive manufacturing (LFAM — Large Format Additive Manufacturing) enabling rapid AUV hull production at Anduril’s Ghost Shark factory
