The Space Development Agency’s (SDA) resilient layered network of military satellites and supporting elements is now the “Proliferated Warfighter Space Architecture” or PWSA.
The architecture, formerly known as the “National Defense Space Architecture,” was renamed to more specifically reflect the agency’s mission to deliver needed space-based capabilities to the joint warfighter to support terrestrial missions through development, fielding, and operation of a proliferated Low Earth Orbit (pLEO) constellation of satellites.
The spiral development and fielding of SDA’s mesh network has matured successfully, but the constellations’ original name did not accurately convey its current scope and purpose. The new constellation name became effective on January 23, 2023.
Now integrated within the U.S. Space Force, SDA continues the integration of its space acquisition and operations into the overall national defense hybrid space enterprise, including pLEO advancements to support no-fail missions such as end-to-end missile warning, missile tracking, and missile defense. Maintaining technological and military advantages in space for the warfighter requires developing a resilient hybrid architecture through an integrated diversification of orbits and proliferation of satellites.
The constellation name change will have no impact to the SDA mission. Leveraging speed, delivery, and agility, SDA will continue to quickly deliver needed space-based capabilities to the joint warfighter to support terrestrial missions through development, fielding, and operation of the PWSA.
