In the “Accelerated Missile Defense Phase 3” project, the US Space Development Agency awarded manufacturing contracts for 18 missile tracking satellites each to L3Harris and Sierra, with a total value of about 1.75 billion US dollars. L3Harris is responsible for developing missile defense variants equipped with mid-field infrared payloads, and Sierra is responsible for missile warning and tracking satellites. It is expected that all 36 satellites will be deployed in 4 orbital planes by the end of 2028. After this batch of satellites is completed and deployed, the total number of low-orbit tracking satellites throughout Phase 3 will rise to 104, creating a huge satellite defense grid.
