What project 4034 buys
Maritime Strike Tomahawk (MST) modernization effort provides the capability to hit moving maritime targets through mid-course guidance via a third party or seeker mode, to a terminal seeker engagement. MST was designated an ACAT 1 subprogram in FY 2023. Early Operational Capability (EOC) planned in FY 2026. Program of Record will consist of a Quick Reaction Assessment (QRA) to support EOC fielding with continued EOC and IOC testing in FY 2026. This testing will validate seeker software algorithm updates, commensurate Weapons Control System (WCS) and Theater Mission Planning Center (TMPC) software updates.

Project 4034 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 | 64.5 |
| FY2026 | Enacted | 56.3 |
| FY2027 | Request | 16.7 |

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.
Continuation of activities in support of Maritime Strike Tomahawk (MST) in FY 2027 will focus on qualification activities for Initial Operational Capability (IOC) hardware, including Ultra 1.1+ (formerly known as ULTRA 1.2) seeker processor upgrades. Integration efforts will ensure full compatibility and performance between IOC software…

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.
