BWX Technologies Inc

BWX Technologies Inc. derives the vast majority of its revenue from defense contracting, with approximately $2.5 billion of its $2.7 billion in total 2024 revenue coming from military sales. The company is a specialized nuclear components supplier to the U.S. government, with its core business focused on the design, engineering, and manufacture of naval nuclear reactors and components for U.S. Navy submarines and aircraft carriers. This includes the production of fuel elements, reactor components, and heat exchangers specifically for military propulsion systems.

The company’s products are purpose-built for warfare. In September 2025, BWXT was awarded a contract for the supply of high purity depleted uranium (HPDU) for military purposes. Its subsidiary, BWXT Ordnance Tennessee, was also competitively awarded a contract by the National Nuclear Security Administration (NNSA) for the licensing, design, and operation of a High-Assay Low-Enriched Uranium (HALEU) demonstration facility, which supports national security and defense programs. BWXT ranks among the world’s top 100 arms-producing and military services companies.
