This activity requests $16.8M in FY2027, 12% of project 2966, down 25% on FY2026. The R-2A exhibit describes it across FY2026–FY2027, including what the FY2027 money is planned to buy.

What the FY2027 request buys

Verbatim from the R-2A exhibit for project 2966 of PE 0603673N. This is the budget justification's own description of work that has not happened yet — the one thing no other level of the budget carries.

FY2027 planned work

Continue the Full Spectrum Undersea Warfare INP by working the following tasks: - Advanced Technology Development associated with the Multi-Vehicle Torpedo Tube Deployment System (MVTTDS) prototype for Virginia Class submarines, which includes Revolver and Reloader including at sea (on a submarine) Revolver prototype testing and model validation - Continue build of GEN 2 Revolver - Continue Testing of GEN 1 Revolver with UAV and decoy devices Complete advanced development of components and system for at sea operations, including resiliency and reliability of 3 inch Submarine Launched effects buoy. Initiate, using MVTTDS, at sea testing of 6 inch Submarine Launched effects buoy.

FY2026 to FY2027 change

The decrease in funding from FY 2026 to FY 2027 is due to re-aligning funds in FY 2026 to best phase the funds with the scope of advanced technology development in FY 2026 for this INP.

Before the request year

FY2026: the year under way

Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.

FY2026 plans — current year

Continue the Full Spectrum Undersea Warfare INP by working the following tasks: - Advanced Technology Development associated with the Multi-Vehicle Torpedo Tube Deployment System (MVTTDS) prototype for Virginia Class submarines, which includes Revolver and Reloader including at sea (on a submarine) Revolver prototype testing and model validation - Spiral development build of GEN 2 Revolver, incorporating capability improvements for objective payloads - Complete design of GEN 2 Reloader design - Complete advanced development of components and system for at sea operations, including resiliency and reliability of 3-inch Submarine Launched UAV hardware and software for select missions. - Initiate build of GEN 2 Revolver - Initiate Testing of GEN 1 Revolver with UAV and decoy devices

Three years, and no five-year plan

An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.

This activity is 12% of project 2966's FY2027 request and 3.8% of PE 0603673N's. In the request year the activities under a project sum to it exactly; in the current year they under-cover it in about 9% of cases, so an activity's delta can legitimately exceed its parent's and the two must not be compared row to row.
