Surface ASW System Improvement
Abstract
The Surface Anti-Submarine Warfare (ASW) Systems Improvements project will support essential performance enhancements to the AN/SQQ-89A(V)15 Surface Ship ASW Combat System. This project will improve Measures of Performance (MOP) by enhancing operator interface methods and tools; active and passive detection; tracking, classification, and localization; Torpedo Detection, Classification, and Localization (TDCL); sonobuoy data processing and display capabilities; and increasing acoustic sensor frequency bandwidth (Operational Requirements Document (ORD) #667-76-05 titled 'AN/SQQ-89 Improvement Program' and Test & Evaluation Master Plan (TEMP) 802-2). This project will take advantage of the AN/SQQ-89A(V)15 Surface Ship ASW Combat System Open System Architecture (OSA) and Acoustic Rapid Commercial-Off-The-Shelf (COTS) Insertion (ARCI) initiatives to integrate TDCL and ASW sonar and combat system capability improvements. The AN/SQQ-89A(V)15 Surface Ship ASW Combat System is planned as a backfit program for CG47 (select CG59-73 Baseline 3 and 4 ships) and all DDG51 class ships. The OSA and high performance COTS processing hardware on ships fielded with the AN/SQQ-89A(V)15 Surface Ship ASW Combat System provides an opportunity to integrate emergent, transformational ASW and Undersea Warfare (USW) technological improvements that were previously unachievable. The ASW/USW suites on these ships will require periodic upgrades to remain effective well into the 21st century and to pace the threat. Software upgrades developed under this project will target capability increases in high interest areas as prescribed by the Fleet and captured in campaign analysis. To achieve this, the project will package and deliver incremental upgrades every two (2) years to the AN/SQQ-89A(V)15 Surface Ship ASW Combat System production program via an Advanced Capability Build (ACB) spiral development process (ACB-23, ACB-25, etc.). The project has undergone a transition in software development methodology from a legacy waterfall approach to an Agile development, security, and operations (DevSecOps) approach. This new Agile approach involves modern Continuous Integration/Continuous Delivery (CI/CD) modular software architectures, coding, and automated testing to enable much more rapid delivery of updated capabilities as required to address cyber or operational performance needs. The Navy is pursuing a transformation across all Tactical Systems to maximize cyber-resiliency and the speed of capability delivery. The transformation implements an agile development processes comprised of a continuous series of 12-week software program increments in a DevSecOps environment. This process will better align with industry practice and enable the AN/SQQ-89 combat systems to leverage industry capability improvements in Artificial Intelligence (AI) and Machine Learning (ML) and other emerging technologies, while also being more responsive to cyber needs. As ACB delivers, changes are required in the project's software development and integration methodologies to remain well synchronized with the production programs. Instead of delivering an improved ACB to the production programs at the end of development (which the production program then had to integrate, mature, test, and certify), development capabilities will now be integrated into the latest production hardware baseline as they are ready, on a continuing basis. This adds flexibility to the program, allowing urgent changes to be fielded more rapidly, and provides an integrated software build requiring less effort at the end of development. For major capability updates, the project will maintain an every-other-year delivery posture to ensure mature products are supporting Fleet Integrated Logistic Support (ILS) and Training. Primary areas of ASW and USW improvements are as follows: - Undersea Fire Control/Engagement - Localization and Contact Management - Medium Frequency (MF) Pulsed Active Sonar (PAS) - Continuous Active Sonar (CAS) - Acoustic Communications - TDCL - Torpedo Defense - Passive Sonar - Sonar Tactical Decision Aids (STDA)
