What project 0223 buys
The Submarine Combat System Improvement (Advanced) (Non-ACAT) project addresses technology challenges to improve tactical control in littoral and open ocean environments for a variety of operational missions including peacetime engagement, surveillance, battle space preparation, deterrence, regional sea denial, precision strike, task group support, and ground warfare support. These technologies, developed by Navy technology bases, the private sector, ONR, Future Naval Capabilities (FNC), and DARPA are then transitioned. Prototype hardware/software systems are developed to demonstrate technologically promising system concepts in laboratory and at-sea submarine environments. The Advanced Sensor effort develops and tests new sensors and demonstrates large array configurations. Current efforts are directed at towed array sensor technologies, telemetry, and architecture to improve reliability and performance while decreasing program life-cycle costs. For large array configurations, Conformal Acoustic Velocity Sonar (CAVES), Wide Aperture Array (WAA), LVA, and Bow Conformal Array (BCA) technologies are also being pursued. The focus of sensor processing technology efforts through the APB program will address improvements in imaging, tactical control, EW and acoustics, including detection, localization, classification, ranging, tracking, situational awareness, tactical decision aids, command decision support tools and displays and other functions essential to mission success. APB will also develop capabilities related to off-hull cueing and coordination with other platforms. Technologies and/or capabilities developed under this Project will be shared, as applicable to reduce costs and optimize reuse, with development programs for surface ship sonar, Advanced Capability Build (ACB) and surveillance platforms, Advanced Surveillance Build (ASB). ACB and APB are managed under a common development process titled AxB. While each platform retains its uniqueness and focus in functional domains essential to mission success, a premium is placed on development of common capabilities and modular architecture technologies to maximize commonality and cost effectiveness.

The R-2A exhibit — the only level of the budget that describes work that has not happened yet. Activities carry the prior, current and budget year only, no five-year plan. 1 of them describes FY2027 work in enough detail to have its own page; the rest are shown here in full. Coverage is partial across the corpus, so count activities, never total them.

FY2026 to FY2027 change The FY 2026 ($7.400M) to FY 2027 ($4.500M) net budget decrease ($-2.900M) is the result of multiple program and rate adjustments for contractor support services and issues to balance RDT&EN across the DoN and DoW which necessitated a reprioritization of Project 0223 efforts.
FY2026 plans — current year - Conduct at-sea testing of Engineering Development Model (EDM) Open Architecture Telemetry (OAT) array to support transition to PEO UWS production programs. - Analyze at-sea test results and develop test report. - Transition OAT EDM and Technical Data Package (TDP) to PEO UWS production programs. - Initiate OAT development improvements to incorporate new sensors, electronics, and materials. - Identify differences in requirements and design needed for OAT to support other Submarine and Surface Towed Array efforts. - Pursue development of innovative active projector designs to support potential Bow Conformal Array (BCA)-embedded active capability for Virginia Class BLK VII and SSN(X)…

Named performers on project 0223
Performers named in the R-3 exhibit under this project. Share is of the project's whole FY2027 R-3 total — the same denominator the program-element split uses, so the two read on one scale and will not sum to 100% when unnamed or government work is in the mix. Budget-justification contract funding, not obligations.
