On February 15, 2026, the US military achieved a historic first by airlifting a Ward 250 micro nuclear reactor, developed by Valar Atomics, aboard a C-17 Globemaster III from California to Utah. This 5-megawatt, unfueled, container-sized reactor is designed for rapid deployment, aiming to provide independent, reliable energy to military bases.
Key Details of the C-17 Reactor Project:
The Mission (Operation Windlord): The Ward 250 reactor was transported from March Air Reserve Base in California to Hill Air Force Base in Utah.
The Reactor (Ward 250): Developed by Valar Atomics, this microreactor uses TRISO fuel, graphite moderators, and helium coolant. It is designed to generate 5 MW of electricity, enough to power approximately 5,000 homes, according to Valar CEO Isaiah Taylor.
Purpose: The initiative aims to reduce reliance on vulnerable fuel supply lines, providing energy resilience for remote or critical, high-demand, and energy-intensive operations.
Testing: Following transport, the reactor will undergo evaluation at the Utah San Rafael Energy Laboratory (USREL).
Future Plans: The Department of Energy aims to have multiple microreactors operational by mid-2026, with commercial sales potentially starting in 2028.
This operation marks a significant shift toward using modular, portable nuclear power for military and civilian applications, according to reports from The War Zone and NucNet.

Is it fail safe as pebble bed reactors are? It doesn't say, but as it has graphite moderators it probably isn't.
