Ghost Fleet Ship ‘Nomad’ Transited Panama Canal, Headed to California

An experimental unmanned surface vehicle has transited the Panama Canal on the way to its new home in California, USNI News has learned.

Nomad, a former offshore patrol vessel retrofitted with systems to allow the ship to operate autonomously, passed through the Panama Canal this week, according to ship spotters tracking data from Marine A Navy official also confirmed the transit.

Web cameras at the canal’s Miraflores locks showed Nomad en route the Pacific late Tuesday night.

A spokesperson for Naval Surface Forces Pacific referred USNI News to the Office of the Secretary of Defense’s Strategic Capabilities Office when reached on Tuesday. A SCO spokesman acknowledged a request for additional information from USNI News but did not provide comment.

Based near the Austal USA shipyard in Mobile, Ala., Nomad was underway extensively in the Gulf Coast and traveled as far away as Norfolk, Va., for its testing program, according to ship spotters.

Nomad, formerly known as Riley Claire, is one of two known ships SCO created for its Ghost Fleet Overlord experimentation program to test the viability of at-sea autonomous ships.

SCO contracted with Gibbs & Cox and L3 ASV Global in 2018 to convert one craft each into unmanned prototypes. The Pentagon used special contracting rules to prevent disclosure of the contractors and the cost of the Overlord program.

Two existing commercial fast supply vessels were converted into unmanned surface vessels (USVs) for Overlord testing, which will play a vital role in informing the Navy’s new classes of USVs.

The other known Overlord ship, Ranger, completed its own transit to California late last year.

“During this voyage, the vessel traveled over 4,700 nautical miles, 97 percent of which was in autonomous mode — a record for the program. Ghost Fleet Overlord will continue fleet experimentation to inform the Navy’s unmanned concept development,” Pentagon spokesman Cmdr. Josh Frey told USNI News at the time.

Like Ranger, Nomad is eventually headed to join the Surface Development Squadron based out of San Diego, Calif. SURFDEVRON, the Navy’s surface experimentation unit, also operates two Sea Hunter medium USVs, the Zumwalt-class destroyers, early Littoral Combat Ships and other unmanned assets.

The Sea Hunters and the Overlord vessels were transferred to the SURFDEVRON to act as test beds for the Navy to craft a concept of operations for unmanned surface vessels – which the service has argued will be a key component of the future fleet.

Earlier this year, the Navy held its first major exercise utilizing unmanned ships and aircraft along with crewed ships and planes as a proof of concept.

In addition to the Ghost Fleet ships, the Navy is outfitting two more Overlord USVs (OUSVs) to inform the development of its Large Unmanned Surface Vehicle (LUSV) program ahead of a planned Fiscal Year 2023 start for the new class.

“The Navy intends for these ships to be armed with vertical launch system cells to fire off defensive and offensive missiles – with sailors onboard manned ships overseeing targeting and firing decisions, since there would be no personnel on the LUSV,” USNI News reported last year.
“The House and Senate armed services committees have said they’re a long way from feeling comfortable with the concept of operations and the technological maturity and reliability.”

Last year, the Navy awarded $42 million in contracts for LUSV studies. Austal USA, Huntington Ingalls Industries, Fincantieri Marinette, Bollinger Shipyards, Lockheed Martin and Gibbs & Cox each won about $7 million to begin developing LUSV concepts.
