## Summary

Project 2993 — Encapsulated Effector requests $40.6M in FY2027, 26% of the $158.7M requested for program element 0604601N — a restart: funded in FY2025, zeroed in FY2026, funded again now. 4 R-2A activities decompose the request, 4 restarted this cycle. GDMS is the largest named R-3 performer at $15.5M, 38% of the project's FY2027 R-3 total.

## What project 2993 buys

The Encapsulated Effector, Hammerhead, program complements existing shallow-water mines by providing maritime mining capability in deeper water depths. Based on the urgency of the requirement, the Hammerhead program utilizes Section 804 authority to streamline acquisition of an initial capability. The system uses existing kinetic payloads to engage enemy targets and provides a wide area of coverage per each weapon. The program uses a self-contained, propelled weapon to engage the target when a target is detected. The system uses modern sensing and processing technology to enable accurate targeting at increased range and maintains minefield resilience even as weapons are expended against targets. The result is expanded operating areas to restrict or deny adversary access to the intended area while using fewer weapons than traditional mines. Additional efforts include; transitioning an encapsulation system with different end effectors under the Compact Encapsulated Effector (C-ENCAP) future naval capability (FNC) that is managed by the Office of Naval Research (ONR).

**R-3 lines of work:** Product Development; Support; Test and Evaluation; Management Services.
