## Summary

Project 3418 — Advanced Anti-Submarine Lightweight Torpedo requests $78.4M in FY2027, 77% of the $102.2M requested for program element 0604610N — a restart: funded in FY2025, zeroed in FY2026, funded again now. 1 R-2A activity decomposes the request, 1 restarted this cycle. OTA- POM is the largest named R-3 performer at $33.6M, 43% of the project's FY2027 R-3 total.

**Markets:** Shipbuilding & Undersea — matched on the project title only, and no market size is quoted.

## 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.

**R-3 lines of work:** Product Development; Support; Test and Evaluation; Management Services.

## What is NOT on this page

Congressional marks, the R-2 mission description and acquisition strategy, the industry vs government split of the whole request, and related program elements are recorded at **program-element** grain — an NDAA mark lands on a PE, never on a project.
