Mission Space Combat Power (SCP) is the Space Systems Command (SSC) Program Executive Office (PEO) focused on developing and delivering combat power capabilities in and through space while also providing National security deterrence capabilities countering those identified threats to prevail in a space conflict. This includes acquiring, developing, and fielding resilient space capabilities to protect national interests, enable critical infrastructures, and support the warfighter. Space Combat Power was established to stay ahead of emerging threats by partnering with the defense and commercial industry, academia and allied partners to deliver cutting edge technology in support of full and continuous characterization of space, when necessary, prevailing in a multi-domain conflict extending to space. Dedicated acquisition personnel lead the way to enable and deliver next-generation space enterprise solutions through rapid, innovative, and affordable technology leveraging the full spectrum of partnerships. Perpetual and prolific space characterization is a foundational requirement for continued, sustainable use of space. The need is even more urgent in today’s contested and congested space domain where satellites are proliferating, adversaries are demonstrating aggressive behaviors, and additional threats are emerging. These new threats necessitate dominant and resilient combat power that can gain and maintain space superiority. To that end, SSC/SCP is seeking state-of-the-art technology advancements in proliferated low Earth orbit (pLEO) for Space-to-Space Communications by soliciting technology project contracts through this BAA. Purpose To address near-term pLEO technology challenges, the Government, through this solicitation, is seeking advancement in the following two (2) overarching areas: Space-to-space communications and Space Networking FY26 BAA Calls: **Call 1.1:** Link-182 Space-to-Space Comms System Development and Demonstration, two-phase, white papers due 6 Oct 2025 Call 1.2 USSF Proliferated Low Earth (pLEO) Mesh Concepts ## Publications - September 15, 2025: Solicitation, due September 14, 2030 at 3:00 AM EDT.
