Underwater systems: companies, products and buyer research

Anduril Industries

Costa Mesa, CA, United States

Anduril develops defense products spanning autonomous aircraft, counter-drone systems, underwater vehicles, command-and-control software, and other mission systems.

Anduril's published portfolio includes Ghost and Altius aircraft and Lattice software. The product and integration scope matter more than the broad label 'drone company': compare the specific aircraft, payload, software and support being offered. Offering context reviewed September 28, 2026.

Ask which legal entity and product configuration would deliver the requirement, what integration is included, and which customer evidence applies to that configuration. An award matched to Anduril does not by itself identify the aircraft or software involved.
