## What project 643722 buys

In CY 2022 the Space Warfighting Analysis Center (SWAC) identified gaps in protected SATCOM capabilities relative to existing and planned capabilities against current and predicted user needs, with consideration of current and emerging challenges to both operating environments and system deployment. SWAC developed a Force Design (FD) to address these gaps, realigning capabilities and disaggregating mission sets. Protected Tactical SATCOM - Global (PTS-G) is a key and enabling capability of the USSF Force Design (FD) that bridges the gap between the more focused capabilities provided by Protected Tactical SATCOM - Resilient (PTS-R), and the broadly-available but also the lower assured access capabilities provided by existing / emerging MILSATCOM and commercial services. PTS-G also augments current and future warfighter capability with increased global capacity. PTS-G is a moderate degree of assured access communications across military Ka-band and X-band using a disaggregated and proliferated sets of lower-complexity satellites. Space Systems Command (SSC) will develop the PTS-G space and ground systems to provide worldwide assured-access communications for tactical warfighters. PTS-G will consist of space vehicles utilizing military Ka band and X band payloads (PTS-G-Ka and PTS-G-X), and ground infrastructure (system controller/hub with gateways), and will connect to existing Protected Tactical SATCOM Family of Systems ground infrastructure (mission management system and cryptographic key management system) developed under the PTES program, as well as integrating legacy SATCOM waveforms. PTS-G will consist of multiple satellites that can provide either X-band and/or mil Ka-band transponded capability while also supporting the utilization of the PTW Waveform. PTW modems for user terminals will be acquired by each Service and by international partners. Initially, PTS-G will provide capabilities in select regions. PTS-G will target a solution that can provide worldwide coverage. PTS-G will be interoperable with the PTES program to perform management and cryptographic key management for PTW users, but PTS-G will procure and install the associated PTES Joint Hubs and other ground infrastructure to operate the satellites, anchor the data, and perform O&S. In addition, the PTS-R system will be integrated with components of PTES and will be complementary to PTS-G.

**R-3 lines of work:** Product Development; Management Services.

### Protected Tactical SATCOM - Global (PTS-G)

Continuing production of PTS-G space vehicles, completing procurement of HW items, and conducting interface checkout of bus and payload subsystems. The program will begin early integration activities. In addition to space vehicles, the program will continue with interface checkout of Ground Command and Control system, which includes…
