SSN-688 & Trident Modernization
Abstract
SSN-688 & Trident Modernization delivers block updates to Submarine Sonar systems and develops improved Submarine Electronic Warfare (EW) systems. These development activities ensure all Submarine Classes maintain clear acoustical, tactical, and operational superiority over Submarines and Surface Combatants in Joint Littoral Warfare, Joint Intelligence Surveillance Reconnaissance (ISR), Indications and Warnings, Information Operations including Cyber, and Special Operations Force (SOF) support. Current developments are focused on supporting Joint Littoral Warfare, Regional Sea Denial, Strike Group Support, Diesel Submarine Detection, Joint Surveillance and Peacetime Engagement, Space and Electronic Warfare, Intelligence Collection, Maritime Protection, and Joint Strike. FY 2025 funding request reflects a net increase of $4.928 million from FY 2024 to FY 2025. Funding increase is associated with APB-23 design, integration, and testing efforts associated with TI-24, which transitions Acoustic Rapid COTS Insertion (A-RCI) to Development, Cyber Security, and Operations (DevSecOps) in the Technical Insertion (TI)/Advanced Processing Build (APB) TI/APB process to better align with software development industry standards and meet fleet demands for rapid capability deliveries and increased focus on machine learning, automation, and behavioral analysis, Light Weight Wide Aperture Array (LwWAA) technology refresh development.

- Change Summary Explanation
- FY 2023 funding reflects a decrease of (-$3.353) million from previous President's Budget. Funding decrease reflects a Small Business Innovation Research (SBIR) / Submarine Tactical Requirements (STTR) Transfer. FY 2025 funding request reflects a net increase of $2.315 million from FY 2024 to FY 2025 for Proj: 0219. Funding increase is associated with rate adjustments, APB-23 design, integration, and testing efforts associated with TI-24, which transitions Acoustic Rapid COTS Insertion (A-RCI) to Development, Cyber Security, and Operations (DevSecOps) in the Technical Insertion (TI)/Advanced Processing Build (APB) TI/APB process to better align with software development industry standards and meet fleet demands for rapid capability deliveries and increased focus on machine learning, automation, and behavioral analysis, Light Weight Wide Aperture Array (LwWAA) technology refresh development. FY 2025 funding request also reflects a net increase of $2.613 million from FY 2024 to FY 2025 for Proj: 0775. This is for Submarine Tethered Expendable Buoy (STEB) development. STEB will build off a prototype currently in development, funding will also be used to pursue additional communications and imaging capabilities not resident in the current prototype. The FY25 funding increase also supports the development of TI-24 and APB capabilities.
