Aether Aerospace is a defense technology platform that delivers technology products, technology-enabled services and advanced manufacturing solutions to the U.S. Department of Defense and other national security customers. The company was formed in December 2025 through the merger of four firms: CTSi, EXPANSIA, JHNA and TSA. It is backed by Falfurrias Management Partners, a private equity firm, and operates in the United States.
Its technical work spans digital engineering and the development of Digital Engineering Ecosystems, open architecture solutions, modelling and simulation, advanced prototyping, aviation modernisation, unmanned systems and advanced manufacturing. These capabilities are applied to the modernisation of critical aviation and unmanned systems, and to aerospace and defence technology programmes more broadly. In addition to technology products, the company provides mission-focused services built on lean and agile principles to customers including the Department of War, NASA and commercial partners.
Engineering work at Aether Aerospace sits across the combined capabilities of its four founding entities, which are positioned as a single enterprise intended for scalable growth and operational excellence. The company describes its workforce as mission-focused, with an emphasis on strengthening the Warfighter's advantage. Sector exposure covers defence, aerospace, national security, aviation, unmanned systems, space and government contracting.
