According to a Navy Newsstand article, the Los Angeles class improved fast-attack submarine USS Scranton has completed a test involving two Unmanned Undersea Vehicles (UUVs) called long-range mine reconnaissance system (LMRS) robots. The autonomous robots were successfully launched from the sub's forward torpedo tube. They completed navigation to a series of waypoints and then docked with a recovery assembly that extended from the torpedo tube. The UUVs, built by Boeing, navigate with the help of inertial navigations systems, GPS receivers, forward-looking sonar, and side-scan sonar. The also include acoustic and UHF communications abilities. The near-term goal for the UUVs is mine reconnaissance. Longer term plans include surveillance and intelligence gathering, "tactical oceanography", and anti-submarine warfare. Once launced, the robots report back to their mothership or a land based command center every 12 hours. For more details on the program, see the Navy's 85 page UUV program overview (PDF format)
