## Summary

This activity requests $179.6M in FY2027, 70% of project 3220, up 29% 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.** Specific planned construction efforts for FY 2027 include: - Continued fabrication of Missile Tubes and Strategic Weapons Support System (SWSS) kits. - Continued Lead Ship Construction, which includes manufacture of the MTM for lead ship, and integration and test of SWSS systems and Final Operating Capability (FOC) for the land-based test facility. Whole Ship Study and Design: This funding applies to the shipbuilder design, systems engineering, prototyping, and vendor qualification activities needed to execute the schedule for whole ship design and component/technology development for the COLUMBIA submarine, and associated engineering/management efforts. - Complete Maintenance Integrated Logistics Products. - Complete Provisioning Integrated Logistics Products. - Complete Logistics Technical Documentation Products. - Continue specific planned construction efforts from FY 2025 including construction execution on all Super Modules (1, 2, 3, 4, 5, and 6).

**FY2026 to FY2027 change.** Increase due to updated estimate for Component Development efforts and First Article Quad Pack requirements. The increase to Prj 3220 BSO 24 includes growth and MTM performance growth.

## Before the request year

**FY2026 plans — current year.** Specific planned construction efforts for FY 2026 include: - Continued fabrication of Missile Tubes and Strategic Weapons Support System (SWSS) kits. - Continued Lead Ship Construction, which includes manufacture of the MTM for lead ship, and integration and test of SWSS systems and Final Operating Capability (FOC) for the land-based test facility.
