Anti-Submarine Warfare (ASW) Mission Package
Abstract
The ASW MP enables LCS to conduct detect-to-engage operations against submarines. Specific ASW capabilities include protecting forces in transit, protecting joint operating areas, and establishing ASW barriers. The ASW MP provides the warfighter capabilities that can be employed for ASW area search as well as high value unit escort missions. Key components of the ASW MP include a Variable Depth Sonar, a Multi-Function Towed Array and sonar signal processing systems. The individual systems are combined into modules: an ASW Escort Mission Module (EMM) that provides High Value Unit (HVU) escort capability and an Aviation Module that offers airborne threat localization and engagement capability through a MH-60R with MK54 torpedoes. This project delivered the ASW EMM Pre-Production Test Article (PPTA) and the Aviation Module in Q1 FY 2019. Following the delivery of the PPTA, the ASW MP was installed on board a Freedom variant hull in Q4 FY 2019 to support Developmental Testing (DT). The project conducted DT on USS Fort Worth (LCS 3) in FY 2020 and FY 2021. In FY 2021, design updates were incorporated to improve reliability and hydrodynamic performance in turns and at higher speeds. Testing at the end of FY21 indicated hydrodynamic and transducer issues had not be resolved. In FY 2022, the program continued hydrodynamic maturation efforts for the PPTA through land-based test events held at the Large Cavitation Channel (LCC) and implementation of an active control solution. Testing at Seneca Lake to show improved transducer reliability was also conducted. The program plans additional transducer testing at Seneca Lake and multiple underways on LCS 3 to ensure active control changes to the PPTA improve hydrodynamic stability and support validation of ASW performance requirements. The Program is also planning and supporting a NATO exercise to conduct ASW operations with an Unmanned Surface Vehicle paired with an alternative ASW payload. In FY 2023, the LCS ASW MP will be divested in alignment with the decommissioning of eight (8) LCS ships. FY 2023 events will occur simultaneously with divestment of the LCS ASW MP. Divestment actions will include continuing performance testing of the DART PPTA with DT and an Operational Assessment validating the ASW performance requirements and the certification of all logistics products delivered in FY23. The Program will conduct foreign comparative testing of ASW capabilities and continue supporting technology demonstrations with unmanned surface vehicles paired with ASW payloads. Also conduct modeling, simulation, analysis, of a Variable Depth Sonar (VDS) in support of the ASW MP and as part of risk reduction efforts for the FFG-62 program.
