L3Harris Completes Design Review for SDA Tranche 3 Missile Tracking Satellites
L3Harris Technologies (NYSE: LHX) completed the Preliminary Design Review for the Space Development Agency’s Tracking Layer Tranche 3 program, advancing development of its next-generation space-based missile warning and tracking system.
The review confirms the baseline design for L3Harris’ Tranche 3 mission solution, which includes satellites, ground systems, networking, communications and infrared payloads. The system is designed to provide infrared sensing, advanced on-orbit data processing and real-time threat detection, supporting near-continuous global tracking of missile threats once deployed.
L3Harris received the SDA contract in December 2025 to design and build 18 spacecraft for the Tranche 3 Tracking Layer. The company said it now has more than 70 missile tracking and defense satellites on order for the Proliferated Warfighter Space Architecture.
The satellites will operate as part of the SDA’s broader layered missile defense architecture and are intended to strengthen detection and tracking of advanced ballistic and hypersonic threats.
