## Summary

U.S. Navy funding falls 30% to a $18.6M request in FY2027 (down from a FY2026 peak). In the FY2027 defense authorization, the House funded it in full; the Senate funded it in full; House appropriators funded it in full. HII leads the industry work, though an unusually large share flows to government labs and warfare centers.

### Project 2474 — LPD Flight II Design & Total Integration

LPD 17 Flight II will replace LSD 41 Class ships and LSD 49 Class ships for embark, transport, control, insert, sustainment, and extract of Marine Air-Ground Task Force elements and supporting forces by helicopters, landing craft, and amphibious vehicles. This project includes efforts to reduce the cost of building and repairing ships, resolving obsolescence issues, and improving shipbuilding industry productivity through: advanced technology and processes with emphasis towards developing ship hull, mechanical, propulsion, electrical, aviation, warfare system, combat support system, sub-systems and components to maintain manpower, survivability, operational capabilities, and pursue affordability initiatives. This program element includes the planning & documentation for Developmental Test and Evaluation (DT&E), Live Fire Test & Evaluation (LFT&E), Operational Evaluation (OPEVAL), and Follow-on Operational Test and Evaluation (FOT&E) tests required for LPD 17 Flight II. These test events will be conducted on the lead Flight II Ship (LPD 30) or where configuration supports capabilities on LPD 29. The test events will be conducted as needed on Flight II follow ships (LPD 31/32) for verification of correction of deficiencies (VCD) from the lead Flight II Ship (LPD 30) as well as design/system changes.

**Named R-3 performers** (share of this project's FY2027 R-3 total, so they need not reach 100%)**:** HII (3.0, 16%), OPTEVFOR (1.5, 7.9%), JTIC/MCOTEA (0.1, 0.4%).

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |
|---|---|---|---|
| LPD Flight II DESIGN/TOTAL SHIP INTEGRATION | 9.7 | 26.7 | 18.6 |

> R-2A activities carry the prior, current and budget year only — no five-year plan. Coverage is partial, so count them, never total them.

## Where the FY2027 request goes

| Category | Share | $M |
|---|---|---|
| Industry primes | 24% | 4.5 |
| Government labs & warfare centers | 59% | 10.9 |
| Other / unspecified | 17% | 3.1 |

**Top named industry performers:** HII ($3.0M, 16%), OPTEVFOR ($1.5M, 7.9%).

> R-3 exhibit contract funding, not USAspending obligations.
