Full Specifications

SBIRS GEO Missile Warning Satellite System

The SBIRS GEO missile warning satellite is a core part of the United States early warning and space surveillance architecture. Designed to detect missile launches within seconds, SBIRS GEO plays a direct role in homeland defense, nuclear deterrence, and global threat awareness.

Developed for the U.S. Air Force and now operated by the U.S. Space Force, the Space Based Infrared System Geosynchronous Earth Orbit satellites replace older Defense Support Program systems. Lockheed Martin serves as the prime contractor, with payload sensors supplied by Northrop Grumman. The satellites operate from geosynchronous orbit, allowing continuous monitoring of large regions of the Earth.

Mission Role and Capabilities

SBIRS GEO satellites use advanced infrared sensors to detect the heat signatures produced by ballistic missiles, hypersonic glide vehicles, and space launches. The system can track missile trajectories from boost phase through midcourse, providing early warning data to U.S. Strategic Command, missile defense systems, and allied forces.

Beyond missile warning, SBIRS GEO supports technical intelligence, battlespace awareness, and space domain monitoring. Its sensors can detect aircraft, large explosions, and reentry events, offering multi mission utility.

Operational Use and Integration

Data from SBIRS GEO feeds directly into ground based missile defense networks, including NORAD and U.S. Space Command. The satellites operate continuously and are designed for long service life, with on orbit redundancy and hardened systems to survive space threats.

SBIRS GEO Missile Warning Satellite Price

The estimated cost of a single SBIRS GEO satellite is approximately USD 1.5 to 2 billion, including payload, launch, and ground integration. Exact figures remain classified due to national security considerations.
