Space Defence

Proliferated LEO constellations deploy hundreds of small satellites in mesh networks that maintain capability even if individual satellites are destroyed, replacing the traditional model of a few exquisite, expensive satellites. Space domain awareness systems detect, track, and characterize objects in orbit including adversary satellites and debris using ground-based sensors, space-based sensors, and AI-powered analytics. On-orbit servicing includes satellite refueling, repair, inspection, and maneuvering capabilities. Resilient communications use cross-linked satellite networks to maintain connectivity even under jamming or physical attack. Link 16 tactical data links enable direct satellite-to-warfighter communications.

Missile warning satellites in the PWSA detect and track ballistic and hypersonic missile threats from launch through impact, providing data to missile defense systems in seconds. Space domain awareness tracks thousands of objects in orbit to prevent collisions, detect threats, and characterize adversary satellite behavior. Resilient communications constellations maintain military connectivity even under electronic warfare and jamming. On-orbit servicing extends the useful life of strategically positioned satellites worth hundreds of millions of dollars. Satellite-based positioning, navigation, and timing provides the foundation for precision-guided munitions and military operations worldwide.

The global space defense market reached approximately $62 billion in 2025 and is projected to exceed $116 billion by 2034 at 7.2% CAGR. North America commands 40% market share ($24.9 billion). The U.S. Space Force base budget request for FY 2026 was $26.3 billion, with potential total spending approaching $40 billion including reconciliation funding. The SDA awarded $3.5 billion in Tranche 3 contracts alone. SpaceX holds approximately $6 billion in DoD contracts extending into the 2030s.
