What project 3418 buys
The MK 54 MOD 2 program is continuing incremental development of lethality required to prosecute challenging adversary submarines. FY 2025 funding will be used to complete the POD designs, and receive delivery of the POD hardware and the Technical Data Package (TDPs), and commence development efforts of an Adapter section that enables the assembly of the MOD 2 Forebody sections with the legacy MK 54 MOD 0/1 OTTO Fuel Afterbody. FY 2026 funding will be used to award a contract to an industry Prime, funding the Rapid Prototyping of the INC 1 All-Up-Round (AUR), which combines the MOD 2 Forebody sections with the legacy OTTO Fuel Afterbody. Funding will also be used to conduct INC 1 AUR integration, which will mate POD sections, the new Adapter section, and the legacy OTTO Fuel Afterbody. The program will also continue operational software development and modeling and simulation verification, and continue de-risking efforts for INC 2, ensuring the Stored Chemical Energy Propulsion System (SCEPS) Afterbody design is mature and ready for Rapid Prototyping at the commencement of the INC 2 phase. FY 2027 funding will be used to continue Rapid Prototyping of the INC 1 AUR contract, AUR and Platform integration, operational software development and modeling and simulation verification and continue engineering in-water testing.

Project 3418 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 | 78.9 |
| FY2026 | Enacted | 0.0 |
| FY2027 | Request | 78.4 |
| FY2028 | Outyear | 95.7 |
| FY2029 | Outyear | 96.0 |
| FY2030 | Outyear | 94.1 |
| FY2031 | Outyear | 95.9 |
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.
- Continue MOD 2 POM INC 1 AUR Rapid Prototyping. - Continue MOD 2 APB-6 operational software development. - Continue performance Modeling & Simulation and EC WAF modeling and simulation accreditation efforts. - Continue All Up Round and Platform Integration. - Continue Land Based Testing and begin Engineering and Set-to-Hit (STH)…

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.
