DARPA Christened "Sea Hunter" ACTUV Prototype Vessel for Persistent Anti-Submarine Warfare

DARPA held a christening ceremony for the technology demonstration vessel it has developed and built through the Agency’s Anti-Submarine Warfare (ASW) Continuous Trail Unmanned Vessel (ACTUV) program. Taking place in Portland, Oregon, the event marks the vessel’s formal transition from a DARPA-led design and construction project to a new stage of open-water testing to be conducted jointly with the Office of Naval Research (ONR).

PORTLAND, Ore. (Apr. 7, 2016) Sea Hunter, an entirely new class of unmanned ocean-going vessel gets underway on the Williammette River following a christening ceremony in Portland, Ore. Part the of the Defense Advanced Research Projects Agency (DARPA)'s Anti-Submarine Warfare Continuous Trail Unmanned Vessel (ACTUV) program, in conjunction with the Office of Naval Research (ONR), is working to fully test the capabilities of the vessel and several innovative payloads, with the goal of transitioning the technology to Navy operational use once fully proven.

“Although ACTUV will sail unmanned, its story is entirely about people,” said Scott Littlefield, DARPA program manager. “It will still be Sailors who are deciding how, when and where to use this new capability and the technology that has made it possible. And we could not have overcome the massive technical challenges to reaching this point without the creative, committed teamwork of our commercial partners and the Office of Naval Research.”

ACTUV is a 130-foot twin-screw trimaran, designed for enhanced stability in all kinds of weather. It has a number of unusual features because it does not need to accommodate people. For example, interior spaces are accessible for maintenance but aren’t designed to support a permanent crew.

But of broader technical significance is that ACTUV embodies breakthroughs in autonomous navigational capabilities with the potential to change the nature of U.S. maritime operations. Through at-sea testing on a surrogate vessel, ACTUV’s autonomy suite has proven capable of operating the ship in compliance with maritime laws and conventions for safe navigation—including International Regulations for Preventing Collisions at Sea, or COLREGS. ACTUV accomplishes this feat through advanced software and hardware that serve as automated lookouts, enabling the ship to operate safely near manned maritime vessels in all weather and traffic conditions, day or night.

ACTUV is designed to normally operate under sparse remote supervisory control but can also serve as a remotely piloted vessel, should the mission or specific circumstances require it. In either case, it would operate at a fraction of the cost of manned vessels that are today deployed for similar missions.

In September 2014, DARPA signed a Memorandum of Agreement (MOA) with the Office of Naval Research to jointly fund an extended test phase of an ACTUV prototype. DARPA will collaborate with ONR to fully test the capabilities of the vessel and several innovative payloads during open-water testing scheduled to begin this summer off the California coast after preliminary checkout and movement to San Diego. Pending the results of those tests, the program could transition to the U.S. Navy by 2018.
