The US Department of the Navy is soliciting offers for commercial on-site SMRs and microreactors to power its installations — extending its decades-long use of naval nuclear reactors for aircraft carriers and submarines to shore-based energy security. The Navy's global network of bases faces energy vulnerability from grid disruptions. Multiple SMR and microreactor developers including Holtec, Oklo, and BWXT are positioning for Navy contracts. This represents a major potential procurement pipeline beyond commercial utility markets.
