(NET) Falcon 9 B5 • SDA-1A

A SpaceX Falcon 9 Block 5 rocket will launch 21 Tranche 1 operational satellites for the U.S. military’s Space Development Agency PWSA (Proliferated Warfighter Space Architecture) constellation. The Falcon 9 booster is designated as B10XX.X for this flight. - Once fully operational, the SDA Tracking Layer will consist of a proliferated heterogeneous constellation of Wide Field of View (WFOV) space vehicles (SVs) that provide persistent global coverage and custody capability combined with the Missile Defense Agency (MDA) Hypersonic and Ballistic Tracking Space Sensor (HBTSS) Medium Field of View (MFOV) SVs that provide precision global access capability. This set of contract awards will initiate the development of the first eight low-cost proliferated WFOV SVs. The capability demonstrated by the Tracking Layer Tranche 0 will provide missile warning and tracking information to national defense authorities, and tracking and cueing data for missile defense elements. Each satellite will have a “wide field of view” overhead persistent infrared (OPIR) sensor capable of detecting and tracking advanced missile threats from low Earth orbit. The satellites will also be equipped with optical crosslinks to pass data to the Transport Layer relay satellites. The first phase of SDA’s Proliferated Warfighter Space Architecture consists of 28 satellites (Tranche 0 including 20 communications payloads made by Lockheed Martin and York Space, and eight missile-tracking infrared sensor satellites made by SpaceX and Leidos) as a proof of concept for the missile tracking and data relay network, followed by more than 150 additional satellites to provide an initial operational capability. Combining conventional tactical radio links, laser inter-satellite communications, and wide-view infrared sensors, hundreds more SDA spacecraft could launch later as the Pentagon ramps up efforts. - Delayed from September, December and Q2.
