Navy Launches UAV from Submerged Submarine

The U.S. Naval Research Laboratory (NRL) with funding from SwampWorks at the Office of Naval Research (ONR) and the Department of Defense Rapid Reaction Technology Office (DoD/RRTO) demonstrated the launch of an all-electric, fuel cell-powered, unmanned aerial system (UAS) from a submerged submarine. From concept to fleet demonstration, this idea took less than six years to produce results at significant cost savings when compared to traditional programs often taking decades to produce results.

“Developing disruptive technologies and quickly getting them into the hands of our sailors is what our SwampWorks program is all about,” said Craig A. Hughes, Acting Director of Innovation at ONR. “This demonstration really underpins ONR’s dedication and ability to address emerging fleet priorities.”

The successful submerged launch of a remotely deployed UAS offers a pathway to providing mission critical intelligence, surveillance and reconnaissance (ISR) capabilities to the U.S. Navy’s submarine force.

Operating under support of the Los Angeles class submarine USS Providence (SSN 719) and the Naval Undersea Warfare Center-Newport Division (NUWC-NPT), the NRL developed XFC UAS – eXperimental Fuel Cell Unmanned Aerial System – was fired from the submarine’s torpedo tube using a ‘Sea Robin’ launch vehicle system. The Sea Robin launch system was designed to fit within an empty Tomahawk launch canister (TLC) used for launching Tomahawk cruise missiles already familiar to submarine sailors.

Once deployed from the TLC, the Sea Robin launch vehicle with integrated XFC rose to the ocean surface where it appeared as a spar buoy. Upon command of Providence Commanding Officer, the XFC then vertically launched from Sea Robin and flew a successful several hour mission demonstrating live video capabilities streamed back to Providence, surface support vessels and Norfolk before landing at the Naval Sea Systems Command Atlantic Undersea Test and Evaluation Center (AUTEC), Andros, Bahamas.
