## Summary

U.S. Navy funding falls 72% to a $16.3M request in FY2027 (down from a FY2026 peak), sustained across the five-year plan. In the FY2027 defense authorization, the House funded it in full; the Senate funded it in full; House appropriators funded it in full. NAWC-WD leads the industry work, though an unusually large share flows to government labs and warfare centers.

### Project 6640 — NSM Range Extension

As the primary offensive munition in the Marine Corps Ground Based Anti-Ship Missile (GBASM) capability, improving the capability of the Naval Strike Missile (NSM) is a Force Design priority central to the Marine Corps' contribution to the Naval Expeditionary Force's (NEF) surface warfare campaign. The NSM includes the missile, booster, shipping/launch container, flight software and associated items. The goal is to double the range of the current NSM missiles over the next five years. Incremental range improvements may be implemented earlier in the production baseline as they complete testing.

**Named R-3 performers** (share of this project's FY2027 R-3 total, so they need not reach 100%)**:** NAWC-WD (2.5, 25%), MCSC (0.7, 6.7%).

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |
|---|---|---|---|
| NSM Range Extension | 9.1 | 9.9 | 9.8 |

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

### Project 6637 — Ground Based Anti-Ship Missile

As the Marine Corps' first Ground Based Anti-Ship Missile (GBASM) capability, the Navy/Marine Expeditionary Ship Interdiction System (NMESIS) is a force design priority central to the Marine Corps' contribution to the Naval Expeditionary Force's (NEF) surface warfare campaign. This project includes design, development, and tests of the NSM launcher, ROGUE-Fires carrier, Leader kit, Weapons Control System (WCS), and Command and Control (C2) connections to enable the transport and firing of NSMs. In FY 2026, NMESIS continued development, testing and integration of Common C4 Phase 2, M-CODE receivers, Weapon Control System (WCS), and Leader/Follower software improvements. In FY 2027, NMESIS will complete Common C4 Phase 2 and WCS improvements while continuing integration and testing of Common C4 Phase 2, M-CODE receivers, and Leader/Follower software improvements.

**Named R-3 performers** (share of this project's FY2027 R-3 total, so they need not reach 100%)**:** MCSC (0.2, 2.8%).

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |
|---|---|---|---|
| Navy Marine Expeditionary Ship Interdiction System (NMESIS) | 39.9 | 19.1 | 6.5 |

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

### Project 9999 — Congressional Adds

FY 2026 Congressional Add for ROGUE-Fires purchased test assets and continues the integration and testing of Leader/Follower software improvements.

## Where the FY2027 request goes

| Category | Share | $M |
|---|---|---|
| Industry primes | 20% | 3.3 |
| Government labs & warfare centers | 41% | 6.7 |
| Other / unspecified | 39% | 6.3 |

**Top named industry performers:** NAWC-WD ($2.5M, 15%), MCSC ($0.8M, 5.1%).

## Mission & acquisition strategy

As the Marine Corps' first Ground Based Anti-Ship Missile (GBASM) capability, the Navy/Marine Expeditionary Ship Interdiction System (NMESIS) is a priority central to the Marine Corps' contribution to the Naval Expeditionary Force's (NEF) anti-surface warfare campaign. This is a critical Service modernization capability requirement focused specifically on countering the Nation's pacing threat. Ground based launchers add a new type of threat against peer adversary, stress different surveillance, and offensive systems, are hard to detect and track in a cluttered environment and add a significant level of persistence and depth to existing anti-ship capabilities.

The GBASM concept started as an effort to conduct a live-fire, guided flight demonstration of ground based anti-ship capability to inform future requirements. The program entered Milestone B in July 2021 and was designated ACAT III with a tailored MCA program. In October 2023, NMESIS was granted Milestone C and re-designated as an ACAT II. The NMESIS program leveraged a prototype development effort to integrate the existing Naval Strike Missile (NSM) onto a tele-operated Joint Light Tactical Vehicle (JLTV) based launcher called the Remotely Operated Ground Unit for Expeditionary Fires (ROGUE-Fires), and develop/integrate the C2 and mobility control components onto a separate manned command vehicle.
