Lockheed Martin has now disclosed that during the Annual Navy Technology Exercise (ANTX) in August, it successfully launched a Vector Hawk canister-launched small unmanned aerial vehicle from its Marlin MK2 autonomous underwater vehicle (AUV).
To transmit the launch command to the Marlin, Lockheed engineers relied on the Submaran, an unmanned surface vehicle (USV) developed by Ocean Aero, as a relay.
