C-17 Airlift Under Operation Windlord Moves Unfueled Ward250 Reactor to Utah

A C-17 Globemaster operating under Operation Windlord moved modules of Valar Atomics' Ward250 microreactor from March Air Reserve Base in Southern California to Hill Air Force Base in Utah on February 15, 2026, Pentagon materials and reporting show. The reactor arrived unfueled and is slated to be transported from Hill AFB to the Utah San Rafael Energy Lab in Orangeville for testing and evaluation.

The Pentagon framed the flight as a joint DoD-DOE effort tied to White House energy priorities and published images on X showing the reactor loaded aboard the C-17. The department posted: “.@DEPTOFWAR is proudly partnering with @ENERGY to advance America's nuclear energy dominance as part of President Trump's Executive Order. Today, we are airlifting a next-generation nuclear reactor—HISTORIC!”

A Pentagon release emphasized the national security rationale for the lift, saying, “The successful delivery and installation of this reactor will unlock significant possibilities for the future of energy resilience and strategic independence for our nation’s defense, showcasing an agile, innovative, and commercial-first approach to solving critical infrastructure challenges. By harnessing the power of advanced nuclear technology, we are not only enhancing our national security but championing a future of American energy dominance.”

Operational and logistical details in reporting highlighted why the Defense Department is testing transport scenarios for compact reactors. Washington Times noted the shipment was an “unfueled mobile reactor” and observed that the Ward250 “fit into a C-17,” adding that “some modern mobile reactors can fit onto the backs of pickup trucks.” Washington Times also quoted Michael Duffy, under secretary of defense for acquisition and sustainment: “Today’s activity aligns with the broader initiative to improve the speed, safety and effectiveness of advanced nuclear reactor testing and to better understand the logistics, certification and handling requirements associated with these systems.” The same report added, “For the Department of War to deploy transportable nuclear micro reactors, many logistics scenarios need to be tested through demonstrations like these to develop a robust understanding of the challenges involved.”

Event logistics at Hill AFB included a public remarks schedule listed by Yahoo: “Undersecretary of War for Acquisition and Sustainment Michael Duffey, Energy Secretary Chris Wright, Utah Governor Spencer Cox, and Taylor are scheduled to speak at Hill Air Force Base at 2:30 p.m. MT following the reactor’s arrival. The event will stream on war.gov and Department of War channels.”

Yahoo also tied the operation to Executive Order 14301, reporting that the order “directs federal agencies to accelerate domestic nuclear innovation and sets a target of achieving reactor criticality on U.S. soil by July 4, 2026.” After arrival at Hill AFB, crews are to move Valar Atomics' Ward250 to USREL or the Utah San Rafael Energy Research Center in Emery County for extended testing that Pentagon materials say will shape handling, certification, and grid-integration strategies for micro nuclear reactors at critical installations.
