L3Harris Technologies has been awarded a contract of up to $919 million to design and build 18 infrared space vehicles for the Space Development Agency’s (SDA) Tranche 2 (T2) Tracking Layer program.

This program will provide near-global missile warning and tracking coverage.

The company has previously designed, developed, and built four satellites for the SSA’s Tranche 0 (T0) Tracking Layer program and is building a 16-vehicle satellite constellation for theSDA’s Tranche 1 Tracking Layer program.
