SUMMARY:(NET) Falcon 9 B5 • PWSA
DTSTART;VALUE=DATE:20260801
DTEND;VALUE=DATE:20260802
UID:283368923105
DESCRIPTION:A SpaceX Falcon 9 Block 5 rocket will launch 21 operational s
 atellites for the U.S. military’s Space Development Agency PWSA (Prolife
 rated Warfighter Space Architecture) constellation. The Tranche 1 satellit
 es (codenamed ?) on this flight are for the Transport Layer and were built
  by Northrop Grumman. The mission is designated as SDA-T1TL-A and the Falc
 on 9 booster is B10XX.X for this flight. The 2nd stage is equipped with a 
 Mission Extension Kit. Comprising a gray band on the RP-1 tank\, extra hel
 ium bottles & batteries\, this kit extends the life of the stage in-orbit\
 , allowing it to deploy the payload directly into its operational orbit.\n
 -\nOnce fully operational\, the SDA Transport Layer will consist of a prol
 iferated heterogeneous constellation of data relay space vehicles (SVs) th
 at provide persistent global coverage through a mesh network comprised of 
 communication satellites that connect to one another and to other space ve
 hicles and ground stations via optical intersatellite links (OISLs). By na
 ture of the mesh network spanning the globe\, the Transport satellites wil
 l also be able to transmit precise position\, navigation and timing (PNT) 
 data to enhance GPS. A-class satellites have at least four optical cross-l
 inks\, that is so they can talk to satellites that are in plane with one a
 nother as they're traveling and they also can talk to satellites that are 
 cross-plane or in completely different orbits. So they can maintain those 
 four lines of communication simultaneously. The B-class satellites will co
 nnect directly to the warfighters via the Link-16 military communications 
 system. They have two optical cross-links each\, so that allows them to ma
 intain constant communication with the other transport satellites in plane
 . The two other nodes will be Link-16 transmitters. Link-16 is an existing
  tactical communication system used across the services primarily for air 
 and ground systems to share low latency data.The first phase of SDA’s Pr
 oliferated Warfighter Space Architecture consists of 28 satellites (Tranch
 e 0 including 20 communications payloads made by Lockheed Martin and York 
 Space\, and eight missile-tracking infrared sensor satellites made by Spac
 eX and Leidos) as a proof of concept for the missile tracking and data rel
 ay network\, followed by more than 150 additional satellites to provide an
  initial operational capability. In total\, Tranche 1 will consist of 154 
 operational satellites: 126 in the transport layer developed by York\, Nor
 throp Grumman\, and Lockheed Martin\, and 28 focused on missile warning an
 d tracking developed by Northrop Grumman and L3Harris. Combining conventio
 nal tactical radio links\, laser inter-satellite communications\, and wide
 -view infrared sensors\, hundreds more SDA spacecraft could launch later a
 s the Pentagon ramps up efforts and integrates new capabilities.\n-\nDelay
