| U.S. Navy Launches XFC 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 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. "This six-year effort represents the best in collaboration of a Navy laboratory and industry to produce a technology that meets the needs of the special operations community," said Dr. Warren Schultz, program developer and manager, NRL. "The creativity and resourcefulness brought to this project by a unique team of scientists and engineers represents an unprecedented paradigm shift in UAV propulsion and launch systems." The NRL Chemistry and Tactical Electronic Warfare Divisions team includes the design-builder of the Sea Robin, Oceaneering International Inc., Hanover, Md.; the fuel cell developer Protonex Technology Corp., Southborough, Mass.; and NUWC-NPT's Autonomous and Defensive Systems Department for Temporary Alteration (TEMPALT) and test demonstration support. The XFC is a fully autonomous, all electric fuel cell powered folding
wing UAS with an endurance of greater than six hours. The non-hybridized
power plant supports the propulsion system and payload for a flight
endurance that enables relatively low cost, low altitude, ISR missions.
The XFC UAS uses an electrically assisted take off system which lifts
the plane vertically out of its container and therefore, enables a
very small footprint launch such as from a pickup truck or small surface
vessel. |
