## What project S1684 buys

This project provides for the Engineering and Manufacturing Development (EMD) of combatant craft, combatant craft mission equipment, Pre-Planned Product Improvement (P3I), and technology insertion to meet the unique requirements of Special Operations Forces (SOF). This project also provides for pre-acquisition activities (materiel solutions analysis, advanced component development and prototypes) to quickly respond to new requirements for maritime craft and subsystems, leading to increased lethality and survivability of personnel and equipment. The craft capabilities and unique equipment provide small, highly trained forces the ability to successfully conduct operations associated with SOF maritime missions. The FY 2026 request for Maritime Systems includes $120.745 million of discretionary and $180.813 million of mandatory (reconciliation) funding for a total of $301.288 million.

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