What project 4033 buys
The M-Code (ACAT IVT) Increment I program upgrades the Tactical Tomahawk to the next generation Global Positioning System (GPS) satellite constellation required to maintain GPS-provided position, navigation, and timing (PNT) for the missiles utilizing M-Code capable Anti-Jam GPS Receiver (AGR5) and is planned for Milestone C production decision in FY 2028 and Initial Operating Capability (IOC) in FY 2030. AGR software and hardware development delays resulted in a schedule breach to the TACTOM M-Code APB Milestone C threshold of February 2026. This resulted in realignment of FY 2026 funds for Pre-Production/Proof of Design and Proof of Manufacturing units. The M-Code mandate and Public Law restricts the purchase of only M-Code-capable GPS User Equipment (MGUE) after FY 2017 unless a waiver is granted by the Secretary of Defense.

Project 4033 funding, FY2025–FY2031
Prior years are actuals, the budget year is the request, and the outyears are the FYDP plan. Estimate types are colored and never summed into one figure. Projects carry the full five-year plan; the activities inside them stop at the budget year.

|---|---|---|
| FY2025 | Actual | 20.4 |
| FY2026 | Enacted | 15.3 |

1 accomplishment / planned program
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. Each 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.
FY 2027 M-Code planned activities include completion of EMD. EMD efforts include Proof of Manufacturing hardware and final software qualification, and achieve Security Approval of an M-Code capable Tactical Tomahawk (TACTOM) AGR5.

Performers named in the R-3 exhibit under this project. Share is of the project's whole FY2027 R-3 total — the same denominator the program-element split uses, so the two read on one scale and will not sum to 100% when unnamed or government work is in the mix. Budget-justification contract funding, not obligations.
