## What project 3343 buys

The Department of the Navy is developing Offensive Anti-Surface Warfare Weapon Increment 2 (OASuW Inc 2), (PU 3343) to address weapon system requirements based on the OASuW Analysis of Alternatives (AoA) and informed by forecast progression in peer competitor naval capabilities. OASuW Inc 2 will be a carrier-suitable, higher-speed, longer-range, air-launched weapon system providing superior Anti-Surface Warfare capabilities. The program is part of the Navy's Long Range Fires investment approach to meet objectives of the National Defense Strategy. As a key component of this strategy, OASuW Inc 2 will address advanced threats from engagement distances that allow the Navy to operate in, and control, contested battle space in littoral waters and Anti-Access/Area Denial (A2/AD) environments. The program will leverage and further advance foundational achievements in the joint Science and Technology (S&T) enterprise, making targeted investments in Navy integration of critical system attributes. User priorities, in the form of pacing the evolving maritime threat, will be the centerpiece of the system requirements and the associated development and fielding schedule. Additional details are Classified.

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

### OASuW Increment II Development Program

**FY2027 planned work.** FY 2027 was reduced to fund other higher Navy priorities.

**FY2026 to FY2027 change.** Decrease from FY 2026 to FY 2027 supports the departments shift from OASuW Inc 2/HALO reducing to applicable levels to enable technological maturation and risk reduction efforts for subsystems to achieve the exquisite service validated requirements and to fund other higher Navy priorities.

**FY2026 plans — current year.** Initiation of next generation OASuW Inc 2 propulsion and technology maturation efforts. Additional details are classified.
