Call 1.2 Special Instructions
Posted Date: 19 Nov 25
White Papers for Call #1.2 Due: 12:00pm Pacific Standard Time (PST) 17 Dec 25 (Note: Do not submit white papers for focus areas and objectives outside of the Call 1.2 request contained in the Call 1.2 special instructions.)
North American Industry Classification System (NAICS) code for this BAA: 541715 Research and Development, in the Physical, Engineering, and Life Sciences (except Biotechnology). Vendors shall have NAICS code 541715 to participate in the Space-to-Space (S2S) Communication BAA. Vendors shall ensure their SAM.GOV account includes this NAICS code prior to submitting a white paper under any S2S Comm BAA Calls. Anticipated Awards: Multiple agreements are anticipated for Call #1.2. However, the Government reserves the right to select for agreement zero, one, more than one, or a portion of any white paper and subsequent proposal received in response to this announcement. Approach: Two-phase (white paper followed by proposals) Period of Performance (POP): TBD, minimum of 12 months. Objective: The Space Systems Command Spectrum Warfare Division (SSC/SZW), in partnership with the National Reconnaissance Office (NRO), is in the process of fielding a proliferated, integrated, vendor diverse, space-to-space communications mesh in Low Earth Orbit (LEO) leveraging commercial product baselines from across the industrial base. This mesh will form the backbone of the Space Data Network (SDN). To this end, SSC/SZW intends to stand up an “Industry Consortium for Space-to-Space Communications” (ICSSC). This consortium (the ICSSC) will be rooted in a public/private partnership intended to create a collaborative and cooperative environment for solving some of the SDN architecture’s toughest challenges. ICSSC will be made up of selected members of the industrial base and will be tasked to solve technical and integration challenges as SSC fields the proliferated LEO (pLEO) spaceto-space communications mesh, expands system capabilities with new vendors and onboards new space-based and terrestrial users. The ICSSC will not exclusively consider concepts with spacecraft and payload elements from the same vendor but will look at modular and open payload accommodation concepts to enable further interoperability in building out the pLEO mesh of SDN.
The Government is seeking input from industry on how to approach assembling, leveraging, and
