The lamprey is a fish that has survived 360 million years thanks to a simple strategy: sticking to its prey to suck its blood. Lockheed Martin has taken that idea literally to name its new weapon, and the analogy is quite literal.
Lockheed’s new thing is called the Lamprey Multi-Mission Autonomous Undersea Vehicle (MMAUV). It is an underwater drone just over 7 meters long, capable of traveling attached to an allied ship or submarine with a lamprey-like system. While attached to the host ship, it can recharge its batteries using its built-in hydrogen generator.
Secrecy the attack
The Lamprey MMAUV does practically everything, although it is primarily designed for covert missions. It can remain on the seabed, monitoring the enemy without being detected thanks to its acoustic signature profile. practically invisible when sonar.
When the time comes to act, the Lamprey can do almost anything: it deploys decoys to confuse the opponent, it is equipped with anti-submarine torpedoes and, if it rises to the surface, it can also launch aerial drones.
What makes the Lamprey especially striking is that it concentrates in a single system capabilities that until now were distributed across different platforms: surveillance, anti-submarine warfare, deception, attack and aerial reconnaissance. It can operate in a swarm coordinating with other unmanned systems. And it can do so autonomously, making decisions without direct human intervention.
Autonomous submarines
The Lamprey will not be the United States’ first unmanned underwater vehicle. There are precedents such as Boeing’s Orca submarine, with the difference that it cost eight years and 885 million dollars to develop, all so that today it is not clear if it will end up becoming a program in the US Navy.
The Lamprey has been funded internally, which Lockheed vice president Paul Lemmo said has allowed them to “iterate at lightning speed and deliver to the Navy a truly multi-purpose weapon that detects, disrupts, deceives and attacks on its own.” In addition, it boasts that its cost is significantly lower than that of other manned platforms.
But the United States is not the only power exploring unmanned vehicles. China has been developing its own fleet of underwater drones for some time and at the military parade in September 2025 it presented the AJX002, an unmanned underwater vehicle of between 18 and 20 meters capable of operating autonomously, laying mines and networking with other attack systems.
