## Summary

Project 0775 — Submarine Supt Equip Prog requests $33.2M in FY2027, 17% of the $195.4M requested for program element 0604503N, down 2.9% on FY2026. 2 R-2A activities decompose the request, 1 new this cycle. Lockheed Martin is the largest named R-3 performer at $25.6M, 77% of the project's FY2027 R-3 total.

**Markets:** Shipbuilding & Undersea — matched on the project title only, and no market size is quoted.

## What project 0775 buys

AN/BLQ-10 Electronic Warfare (EW) system will continue to add new capabilities via Technical Insertion (TI)/Advanced Processing Build (APB) while working across Submarine Warfare Federated Tactical System (SWFTS) programs to transition to Development Security Operations (DevSecOps) software processes and migrate to a cloud based architecture. The Navy is pursuing a transformation across SWFTS (PE 0604503N Projects 0219, 0236, 0253 and 0775) to maximize cyber-resiliency and the speed of capability delivery. Major capabilities that will be pursued in FY27 include continued development for a Digital Early Warning Receiver (DEWR), upgraded and new tactical software solutions, and continued development of the Submarine Tethered Expendable Buoys (STEB). The Submarine Support Equipment Program (SSEP) is responsible for the development and improvement of submarine EW systems in support of effective operations in the following mission areas: Joint Littoral Warfare; Joint Intelligence Surveillance Reconnaissance (ISR), Indications and Warnings; Electronic Warfare; Information Operations including Cyber; and Special Operations Force (SOF) support. The rapid proliferation of complex radar, communications and navigation equipment available to potential adversaries creates an increasingly dense and sophisticated electromagnetic environment. Sustained and significant improvements to submarine EW systems are required to maintain tactical ship safety and operational effectiveness. As such, EW was raised to a submarine primary mission area in FY2012 by Commander Submarine Forces, and EW is listed as a Tier 1 modernization requirement by the Submarine Tactical Requirements Group (STRG). TI-26 provides a DEWR capability. Additionally, TI-26 looks to improve the basic cloud based architecture developed during TI-22 and TI-24. Funding is critical to developing enabling technologies that will provide maximized electronic spectrum digitization and processing, allowing Submarine EW system to continue to pace the threat. STEB is a 3" Launcher deployed, expendable, free-floating buoy that will communicate with the submarine through a fiber-optic tether providing imaging, Radar Indications and Warning, Radar Direction Finding, and communications. Beginning in FY27, an annual funding line is established for AN/BPS-17 Radio Detection and Ranging (RADAR) improvements.

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

### AN/BPS-17 RADAR Improvements — NEW START

**FY2027 planned work.** - Integrate new RADAR sensors into TI-16/APB-15 software baseline. - Integrate new RADAR sensors into TI-20/APB-19 software baseline. - Fund initial round of competition to identify vendors to develop and produce custom solid-state MMR RADAR sensor.

**FY2026 to FY2027 change.** The $1.233M increase in FY27 is due to initial funding for hardware and software development programs.
