Aether Aerospace

What Aether Aerospace does

Aether Aerospace is a privately held U.S. defense technology company formed in December 2025 through the merger of four entities — CTSi, EXPANSIA, JHNA, and TSA — to deliver digital engineering, systems security, mission engineering, prototyping, and data analytics services to the Department of Defense, NASA, and a smaller set of commercial defense partners. The company is organized around five core service areas: Digital Engineering Ecosystems and Digital Thread, Prototyping and Manufacturing, Systems Security and Program Protection, Data Science/Engineering/Analytics, and Mission Engineering/Operational Analysis/Experimentation. Its proprietary product portfolio centers on Mudbucket®, a registered trademark describing a MOSA-compatible integration approach for incremental modernization of legacy and new defense systems, and N-SITE, a sustainment data workflow platform that converts fragmented sustainment data into prioritized action for engineers and logisticians.

The company operates six U.S. offices covering California, Maryland, Virginia, Alabama, New Hampshire, and Southern California, positioned near major defense customers including Naval Air Station Patuxent River, Army aviation and missile programs in Huntsville, and Pacific Fleet operations in San Diego. Revenue is generated primarily through prime contracts and subcontracts with DoD program offices, NASA procurement channels, and defense prime contractors under professional services and managed services models; pricing is not publicly disclosed and follows government procurement structures. Sales motion is enterprise field sales targeting government program offices and prime contractors, with distribution occurring through direct DoD procurement, NASA contracting, and prime subcontractor channels rather than traditional marketing. The combined entity's growth depends on the integration of four legacy workforces and customer relationships, retainment of incumbent contracts, and productization of Mudbucket® and N-SITE into recurring platform revenue.
