What project 4032 buys
TACTOM missile Navigation and Communications (NAV/COMMs) capability consists of a government furnished TACTOM radio, a government furnished crypto unit, and NAV/COMM specific test equipment. This capability enables the Tomahawk Weapon System (TWS) to utilize an Advanced Communications Architecture (ACA) network for secure tactical communications. The Tomahawk Weapons System (TWS) provides a deep strike land attack capability (Tomahawk Land Attack Missile (TLAM)) and can be launched from both surface ships and submarines via the Tactical Tomahawk Weapons Control System (TTWCS). The ACA Phase II will provide additional capability. Details available at a higher classification. The TACTOM Block V Integrated Single Box Solution (ISBS) radio redesign provides improved Communication (Comms) through the use of an improved software that will expand the platform's capabilities and avoids component obsolescence. The ISBS radio is utilized to send in-flight retargeting commands, employ "loiter" tactic, and transmit health and status.

Project 4032 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.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 17.1 |
| FY2026 | Enacted | 24.9 |
| FY2027 | Request | 7.5 |
| FY2028 | Outyear | 1.5 |
| FY2029 | Outyear | 1.2 |
| FY2030 | Outyear | 1.1 |
| FY2031 | Outyear | 1.1 |
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. Coverage is partial across the corpus, so count activities, never total them.
FY2027 planned work Continue radio redesign development, complete Preliminary Design Review, prepare for the Critical Design Review and begin building engineering units to be delivered in FY 2028.
FY2026 to FY2027 change Decrease in program funding from FY 2026 to FY 2027 is due to phasing of Radio Redesign contracted effort.
FY2026 plans — current year NAV/COMMs planned activities for Radio Redesign include hardware and software development leading to Preliminary Design Review. Activities planned for improving TWS communications over the ACA network include building test assets, hardware and software development, conducting capability testing, as well as planning and preparation for flight tests in support of ACA Phase II.
Named performers on project 4032
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.
