Mission

2 satellites, one by L3Harris and the other by Northrop Grumman, will be launched as the Hypersonic and Ballistic Tracking Space Sensor (HBTSS) mission for the US Missile Defense Agency. These satellites have improved sensitivity to detect and track hypersonic missiles with fainter signatures. 4 SDA Tranche 0 Tracking Layer missile warning satellites by L3Harris will also be on board.
