Surface ASW Cmbt Sys Integr

Abstract

The objective of this Program Element (PE) is to significantly improve existing AN/SQQ-89A(V)15 Surface Ship Anti-Submarine Warfare (ASW) sonar system capabilities through quick and affordable development and integration of emergent, transformational technologies in support of Surface Ship and Theater ASW (TASW) as required to pace the threat. Detection and classification play uniquely vital roles in the success of any ASW campaign. The Advanced Capability Build (ACB) spiral development process is the primary means by which these improvements are developed. ASW remains a Navy core competency in a dynamic and uncertain maritime environment. U.S. adversaries continue to develop asymmetric capabilities and capacities to deter, disrupt, or delay the entry of U.S. and allied naval forces, and pose a constant challenge as we implement the Maritime Strategy. Evolving submarine technologies offer enhanced stealth, speed, endurance, weapons, and operational proficiency, foretelling that the adversary submarine of the future will have a significantly larger sphere of influence, while presenting less vulnerability to U.S. forces. The effective offensive engagement range of the adversary submarine of the future will continue to match or outrange individual U.S. and multinational platform sensors and weapons in many tactical environments. Submarines are an increasing threat to all Naval and Allied ships, particularly modern diesel subs and faster torpedoes. Not only can the presence of potential hostile submarines delay naval combatant action until they are located and neutralized, submarines can also disrupt all seaborne logistics supply for any ground campaign as well as maritime commerce. U.S. forces must be effective in all operating environments, ranging from the deep open ocean to the littorals, and are key to countering adversarial anti-access and area denial strategies. This PE takes advantage of the AN/SQQ-89A(V)15 Open System Architecture (OSA) and Acoustic Rapid Commercial-Off-The-Shelf (COTS) Insertion (ARCI) initiatives to integrate Torpedo Detection, Classification, and Localization (TDCL) and ASW sonar combat system capability improvements. The AN/SQQ-89A(V)15 COTS-based Surface Ship ASW Combat System is planned as a backfit program for all DDG51 class ships. The Open Architecture (OA) system enables the ACB process and provides budget flexibility to make COTS/OA technology solutions and ARCI-type initiatives affordable. Improvements are tested in the laboratory and at-sea. Undersea Warfare (USW) technology implementation will take advantage of improvements developed under the submarine Advanced Processing Build (APB) and Advanced Surveillance Build (ASB) programs and will in turn share unique improvements developed under this program with the submarine and surveillance USW communities. The ACB and APB programs are managed under a common development organization and 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. This PE includes funding for the AN/SQQ-89A(V)15 Surface Ship ASW Test & Evaluation (T&E) program, which conducts testing and analysis to support certification of AN/SQQ-89A(V)15 Surface Ship ASW Combat System ACBs prior to fielding. Additionally, finalization of Test & Evaluation Master Plans (TEMPs) and AN/SQQ-89(V) Developmental Test (DT) and Operational Test (OT) events are conducted under this program. This PE includes funding for the AN/SQQ-89A(V)15 Surface Ship Engineering Measurement Program (SSEMP), which will measure the performance of existing and new AN/SQQ-89A(V)15 Surface Ship ASW Combat System Technical Insertion (TI)/ACB baselines and enables data-based assessment of the capabilities and shortfalls in the performance of these systems in realistic scenarios. After TI-20, there will be a nomenclature shift for hardware baselines. Hypervisor Technology 0 (HT0) will replace what would have been TI-22. HT0 allows for virtual software, creating a separation between hardware and software making both agnostic to one another, which simplifies future upgrades. HT0 also supports the transition to Infrastructure as a Service (IaaS) which builds on the virtualization of software by utilizing common infrastructure. This PE includes funding to support cyber security initiatives to align future AN/SQQ-89A(V)15 Surface Ship ASW Combat System baselines with future AEGIS Integrated Combat Systems. This PE contributes to the development of the ASW component of the guided missile Frigate (CONSTELLATION Class, FFG 62) program.

• Change Summary Explanation: FUNDING CHANGES SINCE PREVIOUS PRESIDENT'S BUDGET: - FY 2023 net decrease of $-1.054M reflects the Small Business Innovative Research (SBIR) transfer ($-1.053M) and a miscellaneous rate adjustment ($-0.001M). - FY 2025 decrease of $-0.190M is the result of programmatic changes (-$.353M) and miscellaneous rate adjustments ($.163M). FY 2024 TO FY 2025 BUDGET REQUEST DECREASE: FY 2024 ($29.973M) to FY 2025 ($29.887M) decrease ($-0.086M) is result of miscellaneous rate adjustments. SCHEDULE CHANGES SINCE PREVIOUS PRESIDENT'S BUDGET: 'ACB-23 Step 4: At-Sea Test' has been shifted from 1Q24 to 3Q24 due to personnel/resource limitations. 'Delivery to Production Program' will remain unchanged in 2Q24. Output from the Step 4 test can still be incorporated into the post-delivery ACB-23 software via the prime system integrator.
