Notice as published

SDA Proliferated Warfighter Space Architecture (PWSA) - Systems, Technologies, and Emerging Capabilities (STEC) Broad Agency Announcement (BAA)

The Space Development Agency (SDA) is soliciting executive summaries, proposal abstracts, and proposals for novel architecture concepts, systems, technologies, and capabilities that enable leap-ahead improvements for future Proliferated Warfighter Space Architecture (PWSA) tranches, capability layers, or, enable new capability layers to address other emerging or evolving warfighter needs. NOTE - Although not required, SDA strongly encourages submitting an executive summary in advance of a full proposal to ensure interest and potential funding availability. SDA releases an updated Broad Agency Announcement (BAA) on an annual basis.

Because SDA strives to always maintain an active BAA with similar focus areas, proposers are discouraged from submitting uninvited full proposals shortly before the BAA proposal due date simply to meet the submission deadline. They should consider instead submitting an executive summary to the subsequent BAA.
