## What project 3469 buys

Scaled Onboard Electronic Attack (SOEA) is an incremental development program by the USN to provide an advanced Electronic Attack (EA) capability against anti-ship missiles. The program is intended to be scalable for Surface Combatants with size, weight, power, and cooling (SWaP-C) constraints that cannot support AN/SLQ-32(V)7; however, it is not intended to replace AN/SLQ-32(V)7. SOEA development executes under a Middle Tier of Acquisition Rapid Prototyping acquisition strategy pursuant to Section 804 of the FY16 National Defense Authorization Act. The SOEA Middle Tier of Acquisition (MTA) leverages technology developed by the Office of Naval Research (ONR) and Naval Research Laboratory (NRL). SOEA's acquisition strategy consists of two phases: Rapid Prototyping and Rapid Fielding. SOEA Phase 1 includes prototyping of critical technology elements (CTEs) via Defense Microelectronics Agency (DMEA) contract agreements to prove out and validate critical performance capability, system architecture functionality, supportability requirements and improvements that build on the CTEs. SOEA Phase 2 will focus on fielding initial capability through the producibility of the Phase 1 prototype, continuing hardware and software improvements to meet full capability objectives, continuing external interfaces for system and platform integration, continuing training module development via the Surface Electronic Warfare Tactical Trainer (SEWTT) and completing Modeling & Simulation (M&S) to support further testing. SOEA will continue to expand the integrated shipboard combat system by providing new integrated EA capability and will be integrated with AN/SLQ-32(V)6. SOEA also includes a government software development and integration effort for a Soft-Kill Coordinator System (SKCS) to manage EA engagements. The FY27 budget request for SOEA supports the continuation of Phase 1 Rapid Prototyping, including performance testing, SEWTT training module development, Modeling & Simulation (M&S) and SKCS integration. The FY27 budget request also supports the initiation of SOEA Phase 2 Rapid Fielding which supports further land-based and environmental testing, initiates software and hardware baseline upgrades, and supports acquisition of additional prototype units.

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