## What project 671201 buys

Budget Program Activity Code (BPAC) 671201 is primarily focused Operational Systems Development for the E-11 BACN platform. Battlefield Airborne Communication Node (BACN) enables tactical edge Joint and Coalition information interoperability via air, space, and surface systems, to include a network for high-capacity data transfer. As requirements emerge, BACN will integrate new hardware and software capabilities that improve system performance, interoperability, availability, prototyping of activities in line with department approach of system development upgrades to support current/future Open Mission System (OMS) technologies. Efforts may include onboard enhancements such as datalink receiving capability in platform cockpit to include but not limited to Link-16, as well as analysis and developmental efforts to explore feasibility of onboard operators to support onboard payload control capabilities. Efforts include, but are not limited to, expansion of external time reference capabilities, development/integration of additional communications systems/subsystems and components such as Military Global Positioning System (MilGPS), M-code or future software and integration of advanced antennas and waveforms, development efforts enabling integration of ABMS/JADC2 capabilities, enhancements to ground support capabilities. Additionally, safety of flight considerations, to include weapon system performance, aircraft structural integrity, availability, continuity of service requirements will be addressed, as well as aircraft avionics upgrades, early system engineering assessments and risk reduction activities associated with weapon system "payload” and "platform” survivability in non-contested through contested environments. Efforts include required non-recurring engineering and Diminishing Manufacturing Sources (DMS) issues, the development of simulators/trainers, development of training materials, the development of future waveforms that are backward compatible with existing communications, and technical publications as well as the assimilation of any mandates levied on the BACN weapon system. Execute risk reduction activities for development of future capabilities on BACN payload/aircraft efforts. This program element may include necessary civilian pay expenses required to manage, execute, and deliver weapon system capability.

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

> Activities carry the prior, current and budget year only — no five-year plan. In the request year they partition this project exactly; in earlier years they can under-cover it.

### M-Code Military Global Positioning System (MilGPS)

**FY2027 planned work.** No budget year FY 2027 funds requested.

**FY2026 to FY2027 change.** The decrease in funding from FY 2026 to FY 2027 is due to removal of further investment funding and moving the program fully into Operations and Sustainment phase in FY 2027. All investment funding moved to higher AF priorities while AF studies other alternatives in the delivery of the communications gateway capability.

**FY2026 plans — current year.** - Will continue test and integration of MILGPS M-Code technology into the BACN E-11A platform and integration. This effort is funded with RDT&E funds for integration, assembly, test, and checkout of systems on two E-11As, and procurement funds for hardware, payload integration, and related activities on the remaining five aircraft. This comprehensive effort will complete software development, integration, and deployment of M-Code across all seven BACN jets, incorporating the necessary Embedded GPS Inertial Navigation (EGI), an Antenna Electronics Unit (AEU), and a Controlled Reception Pattern Antenna (CRPA) to ensure jam resistant capability. Six M-Code units will be utilized during the Research and Development phase—two for the Global Express, two for the Global 6000, and two for additional test articles.
