Astrion

What Astrion does

Astrion is a U.S. defense technology company that provides integrated mission support, advanced engineering, and technology services to federal agencies across defense, homeland security, intelligence, space, and civilian domains. The company was formed from the merger of three government services firms and is privately held under private equity sponsor Brightstar Capital Partners; it completed the acquisition of Axient in September 2024 to expand its defense and civil mission capabilities and to add an international presence via Axient Systems B.V. in the Netherlands. Astrion serves the U.S. Navy, Air Force, Army, Space Force, Missile Defense Agency, and NASA, and operates internationally as mission integrator for the Netherlands' PAMI-1 sovereign imaging satellite program. All revenue is generated through U.S. federal contract vehicles — primarily IDIQ contracts, Other Transaction Agreements (OTAs), and joint ventures — supplemented by allied defense work.

Astrion's core capability portfolio spans Counter-UAS and Unmanned Systems integration, Cyber, Space Technologies, Test/Evaluation/Training, Systems Engineering & Integration (SE&I), Mission Support, and the Golden Dome missile defense architecture. The company's proprietary technology stack includes the PULSE physics-based threat scene generation tool (with a PULSEbox web interface), the GENESIS six-degrees-of-freedom trajectory simulator, the Reliant Core reliability-centered maintenance framework, and the RIMFIRE predictive maintenance software. These tools operate within a distributed, cloud-native LVC (Live, Virtual, Constructive) simulation environment that integrates with DoD platforms such as the Next Generation Threat System (NGTS) and AFSIM. Astrion also operates the Navy's Medium Displacement Unmanned Surface Vessels (Seahawk, Sea Hunter) and supports NASA laboratory operations at Kennedy Space Center.

Astrion generates revenue through direct U.S. federal contracting and through joint ventures such as Beyond New Horizons with Fluor, which secured the $3.7 billion, 12-year Test Operations and Sustainment (TOS) II contract supporting the Arnold Engineering Development Complex. Additional disclosed contract ceilings include $910M for Army Test and Evaluation Command support, $349.4M for the NIWC Pacific unmanned maritime systems IDIQ (through May 2034), and $237M for the Space Force STEP 2.0 contract (10 years). In April 2026, Astrion appointed former Sierra Space CEO Tom Vice as CEO and Executive Chair to lead the next phase of expansion across defense, space, and allied markets.
