SUMMARY:(NET) Falcon 9 B5 • PWSA
DTSTART;VALUE=DATE:20260901
DTEND;VALUE=DATE:20260902
UID:875335756031
DESCRIPTION:A SpaceX Falcon 9 Block 5 rocket will launch 7 operational sa
 tellites for the U.S. military’s Space Development Agency PWSA (Prolifer
 ated Warfighter Space Architecture) constellation. The Tranche 1 satellite
 s (codenamed ?) on this flight are for the Tracking Layer and were built b
 y ?. The mission is designated as SDA-T1TR-C and the Falcon 9 booster is B
 10XX.X for this flight. The 2nd stage is equipped with a Mission Extension
  Kit. Comprising a gray band on the RP-1 tank\, extra helium bottles & bat
 teries\, this kit extends the life of the stage in-orbit\, allowing it to 
 deploy the payload directly into its operational orbit.\n-\nOnce fully ope
 rational\, the SDA Tracking Layer will consist of a proliferated heterogen
 eous constellation of Wide Field of View (WFOV) space vehicles (SVs) that 
 provide persistent global coverage and custody capability combined with th
 e Missile Defense Agency (MDA) Hypersonic and Ballistic Tracking Space Sen
 sor (HBTSS) Medium Field of View (MFOV) SVs that provide precision global 
 access capability. This set of contract awards will initiate the developme
 nt of the first eight low-cost proliferated WFOV SVs. The capability demon
 strated by the Tracking Layer Tranche 0 will provide missile warning and t
 racking information to national defense authorities\, and tracking and cue
 ing data for missile defense elements. Each satellite will have a “wide 
 field of view” overhead persistent infrared (OPIR) sensor capable of det
 ecting and tracking advanced missile threats from low Earth orbit. The sat
 ellites will also be equipped with optical crosslinks to pass data to the 
 Transport Layer relay satellites.The first phase of SDA’s Proliferated W
 arfighter Space Architecture consists of 28 satellites (Tranche 0 includin
 g 20 communications payloads made by Lockheed Martin and York Space\, and 
 eight missile-tracking infrared sensor satellites made by SpaceX and Leido
 s) as a proof of concept for the missile tracking and data relay network\,
  followed by more than 150 additional satellites to provide an initial ope
 rational capability. In total\, Tranche 1 will consist of 154 operational 
 satellites: 126 in the transport layer developed by York\, Northrop Grumma
 n\, and Lockheed Martin\, and 28 focused on missile warning and tracking d
 eveloped by Northrop Grumman and L3Harris. Combining conventional tactical
  radio links\, laser inter-satellite communications\, and wide-view infrar
 ed sensors\, hundreds more SDA spacecraft could launch later as the Pentag
 on ramps up efforts and integrates new capabilities.\n-\nDelayed from Q4 a
 nd Q1.\n\nWebcast:\nhttps://www.spacex.com/launches\nhttps://spaceflightno
