Also known as
  • Lamprey MMAUV
  • Lamprey Multi-Mission Autonomous Undersea Vehicle
  • MMAUV

Lockheed Martin's LampreyMMAUV is a plug-and-play autonomous undersea vehicle publicly unveiled in 2026 for covert access, sea denial, ISR, and seabed-warfare missions. Official material describes a 24 cubic foot internal payload bay, host-ship or submarine attachment, battery recharge while attached, optional UAV launch tubes, and mission kits for torpedoes, decoys, sensors, or other payloads; public sources reviewed for this entry document development and exercise activity rather than confirmed armed-conflict use.

Documented Mission Options

Lockheed Martin describes LampreyMMAUV as a modular undersea vehicle built around host-ship attachment, autonomous undersea maneuver, and a configurable 24 cubic foot internal payload bay.

Host transit

The vehicle can attach to a host surface ship or submarine without host modifications and recharge while attached.
