L3Harris SDA AMDT3 Tracking Layer Satellites
SDA Accelerated Missile Defense Tranche 3 (AMDT3) award to L3Harris for 18 missile-tracking satellites; ~$955M OTA prototype agreement, launch-ready by end of 2028.
On July 13, 2026, the U.S. Space Development Agency awarded L3Harris Technologies a firm-fixed-price OTA prototype agreement worth approximately $955 million to build 18 'HBTSS-like' (Hypersonic and Ballistic Tracking Space Sensor) missile-defense variant satellites across two orbital planes under the Accelerated Missile Defense Tranche 3 (AMDT3) program. The satellites carry medium-field-of-view payloads for fire-control-quality tracking data against hypersonic and ballistic threats, expanding the Tracking Layer of the Proliferated Warfighter Space Architecture (PWSA) supporting Golden Dome for America. L3Harris will manufacture the satellites at its expanded Indiana facility and a new integration facility in Florida, with delivery/launch-readiness required by end of 2028.
