L3Harris announced the completion of CDR design and PRR production readiness testing for 16 real-time hypersonic missile tracking satellites for the U.S. Space Development Agency’s (SDA) tracking program.

Completion of the CDR indicates that the L3Harris project meets mission requirements, and the PRR indicates that the SDA has been approved to begin full-scale production. These achievements represent significant progress in the development of SDA, a network of military satellites in Low Earth Orbit (LEO).

Hypersonic missiles such as Russia’s X-47 Kinjal pose a threat due to their stealth flight characteristics, multiple launch sites and high maneuverability. Overcoming these challenges and ensuring effective deterrence requires the development of a robust sensor platform, such as a satellite, that can track hypersonic missiles in real time.

L3Harris’ contribution to the Tranche 1 Tracking Layer (T1TRK) program concerns the integration of infrared sensors and algorithms into the satellite. These technologies are critical for detecting, monitoring and integrating threat data. The data is then transmitted to military operators via a network using both optical and radio frequency communications.

Additionally, ground control can direct satellites to use different guidance modes, increasing their ability to track potential threats. The program includes not only the development of satellites, but also their ground support, operation and long-term maintenance.

Bob De Kort, L3Harris’ director of program management, leads the team responsible for the design and development of 16 missile tracking satellites. These satellites, planned to be launched in 2025, are equipped with advanced technology designed to combat hypersonic missiles known for their extraordinary speed and maneuverability. Source
