One dated line per material change, oldest first.
2026-08-06 Tracked. Fort Wainwright is one of nine sites the Army named, alongside Fort Benning, Fort Bragg, Fort Campbell, Fort Drum, Fort Hood, Holston Army Ammunition Plant, Joint Base Lewis McChord and Redstone Arsenal. The Army says the sites were chosen on mission criticality, existing energy shortfalls, grid resilience and environmental and technical constraints. The program answers Executive Order 14299 on deploying advanced nuclear reactor technologies for national security, and the Army's stated goal is an operational demonstration plant on a military installation by 2030. No vendor selection for Fort Wainwright has been made public.
2026-08-18 Re-verified. Fort Wainwright remains one of nine Army posts named for a possible microreactor by 2030, and no down selection has been reported since.
2026-08-26 Checked and unchanged. Fort Wainwright is still one of nine Army posts named for a possible microreactor under the Janus program, and no vendor down select has been announced since industry submissions closed on December 15th, 2025. The Army's stated goal is an operating demonstration plant by 2030.
2026-08-30 Decided, and Fort Wainwright is not in it. The Army named its first five Janus installations on August 26th, 2026, Fort Bragg with Antares Nuclear, Fort Campbell with BWXT Advanced Technologies, Fort Hood with General Atomics Electromagnetic Systems, Fort Benning with Radiant Industries and Fort Drum with Westinghouse Government Services, against roughly $2.2 billion running across fiscal years 2027 through 2031 on milestone based payments. Fort Wainwright was short listed and not chosen, alongside Holston Army Ammunition Plant, Joint Base Lewis-McChord and Redstone Arsenal. The program itself continues, so a later round could still reach Alaska, and nothing published says it will.
