What project 67A021 buys
Mission Delta 31 is developing the Next Generation Operational Control System (OCX) (Project 67A021) for Guardians across Position, Navigation, and Timing. As a result, the Service will improve readiness and operational reach of existing force structure. OCX acquisition was established to: 1) provide command and control of legacy and GPS III satellites; 2) incorporate situational awareness to support Navigation Warfare (NAVWAR) and signal monitoring; 3) enable mission capability upgrades to support a warfighter effects-based approach to operations; and 4) integrate DoW information assurance and cybersecurity controls and capabilities. OCX funds will support efforts such as engineering studies and analyses, architectural engineering studies, trade studies, technology needs forecasting, technology development, systems engineering, system development, test and evaluation efforts, pre-operational support activities, and interim contractor support, in support of upgrades and product improvements for military and civil applications necessary to support efforts to protect the United States military and Allies' use of GPS. Additionally, funds will ensure efforts to meet Joint Requirements Oversight Council (JROC) approved required capabilities. OCX Block 0 is the Launch and Checkout System (LCS) intended to conduct Launch and Early Orbit (LEO) operations and the on-orbit checkout of all GPS III satellites. The 2nd Space Operations Squadron (2SOPS) can also call upon OCX Block 0 capabilities at any time to support GPS III anomaly resolution activities. OCX Block 0 is a subset of OCX Block 1. OCX Block 1 fields the operational capability to control all legacy satellites, the legacy civil signal (L1C/A), the legacy military signals (L1P(Y), L2P(Y)) as well as the GPS III satellites and the modernized civil signal (L2C) and the aviation safety-of-flight signal (L5). In addition, Block 1 will field the basic operational capability to control the modernized military signals (L1M and L2M M-Code), and the globally compatible signal (L1C). OCX Block 2 fields the advanced operational capability to control the advanced features of the modernized military signals (L1M and L2M M-Code). Architecture Evolution Plan (AEP), also known as Operational Control Segment (OCS), is the legacy operational control segment for GPS.

The R-2A exhibit — the only level of the budget that describes work that has not happened yet. Activities carry the prior, current and budget year only, no five-year plan. 1 of them describes FY2027 work in enough detail to have its own page; the rest are shown here in full. Coverage is partial across the corpus, so count activities, never total them.
Continue upgrades to modernize the AEP legacy ground control segment system to deliver OCX CDD requirements in place of OCX. Upgrades include GPS IIIF Launch, GPS IIIF C2, SAASM and NGA Receiver Integration. Additional upgrades to system interface tools are planned to support development and fielding of CNAV monitoring CDD requirements…

FY2026 plans — current year Block 0 continues support for the launch checkout and anomaly resolution of GPS III satellites. Continue to perform maintenance activities for Blocks 1 and 2, provide contractor staff to support government activities, and conduct pre-planned system updates to align ground capabilities with GPS enterprise changes involving the space and user segments. Support Integrated System Test (IST), Transition Events, and Operational Readiness Exercises. Execute the Discover, Demonstration and Test (DDT) campaign to efficiently accelerate Deficiency Reports (DR) discovery and resolution. Rapidly respond to implement system resiliency and situational awareness necessary to operate in the contested space…
