## Summary

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

**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 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
