Submarine Acoustic War Dev
Abstract
Submarine Launch Unmanned Aerial System (SLUAS) transferred from RDTEN Program Element (PE) 0604562N beginning in FY25. The Submarine Acoustic Warfare (SAWS) Development Program develops acoustic countermeasures, submarine defense capabilities, external launch systems and all acoustic augmentation systems for the U.S. Navy submarines. The SAWS Development Program is comprised of the Submarine Defensive Warfare Program, Compact Rapid Attack Weapon (CRAW) and Non-Traditional Acoustic Communications (NTAC). Project 1265 Sub Defensive Warfare The first development (Increment 1) effort of the overall Submarine Torpedo Defensive Systems (SubTDS) program is focused on delivering full internal countermeasure launcher (ICL) functionality to all submarine in the fleet via the Acoustic Device Countermeasure (ADC) MK5 effort. The ADC MK 5 acoustic countermeasure (ACAT III) developmental contract awarded in Sep 2018 and is currently in the Engineering and Manufacturing Development (E&MD) phase. The ADC MK5 development includes delivering fully functional test units and Engineering Development Model (EDM) variants. The ADC MK5 will bring new technologies, including adaptability, packaged in a three-inch diameter body. The ADC MK5 efforts include on- going development such as finalizing and testing the overall system in support of Test Readiness Review (TRR), and Production Readiness Review (PRR) and award of multiple ADC MK5 EDM units followed by LRIP units. FY24 funding will include EDM-2 Test Readiness Review (TRR) and will deliver one hundred and twenty-two (122) EDM-2 units. Twenty (20) units to be utilized for Environmental Qualification Testing (EQT), three (3) units to be utilized for HERO testing, and ninety-nine (99) units to be utilized for additional Developmental Testing (DT). Procurement of long lead items for eighty-four (84) Low-Rate Initial Production (LRIP) units will also begin in FY24 in preparation for initial deliveries beginning in FY25. FY24 will complete deliveries of STU-E and continue Hardware-In-the-Loop (HWIL) integration of STU-E into the Weapons Analysis Facility (WAF) testing. FY25 efforts will include Production Readiness Review (PRR) and will begin delivery of the eighty-four (84) LRIP units to be utilized for Operational Testing (OT) beginning in FY26. Independent Logistics Assessment (ILA) will be completed in FY25. Developmental Testing (DT) and Environmentally Centric Weapons Analysis Facility (EC-WAF) / Hardware in the Loop (HWIL) of EDM-2 will continue in FY25. SIB funds received will support Sub TDS industrial base efforts. Additionally, FY25 accounts for procurement of 30 LRIP units that will begin delivery in FY26 and FY26 accounts for procurement of 29 LRIP units that will begin delivery in FY27. The next development in the SubTDS program (Increment 2) focuses on the development of the External Countermeasure Launcher (ECL) hosted 6-inch acoustic countermeasure (to be known as the ADC MK6 effort), Tactical Decision Aid, and integration with ship systems for to provide improved adaptive capabilities leading up to a contract or agreement award in FY25. The Undersea Defense Working Group (UDWG) is a working group comprised of fleet, resource sponsor, (testing community) and acquisition community representatives to assess fleet threats and the effectiveness of our countermeasure systems against these threats, both known and projected. This includes associated studies, demonstrations, models, and simulations. The Technical Direction Agent (TDA) and In-Service Engineering Agent (ISEA) will provide hardware and software development support for Acoustic Devices Countermeasure (ADC) as well as Countermeasures Set, Acoustic (CSA) systems, future variants, and Acoustic Augmentation Support Systems (AASS) in the Acoustic Augmentation Support Program (AASP), and advanced communication systems improvements in support of the AASP, including component level technical insertion. PMS415 Submarine Tethered Expendable Buoy (STEB) effort is limited to the development of changes to the internal countermeasure launcher, specifically the breech door, to integrate STEB. This integration will provide a communications path to and from the buoy, bringing buoy sensor data internal to the submarine. Project 1267 Compact Rapid Attack Weapon (CRAW) Within the CRAW Project line 1267, funding from FY24 to FY25. The FY25 budget supports $10M in procurement of remaining material for TI-2 hardware material and integration and testing of EDM's to be delivered in FY26. The FY25 budget also supports the required software development, hardware development, submarine integration and qualification testing. The CRAW Research, Development, Test & Evaluation (RDT&E) program will deliver a new very-lightweight torpedo capability to the Submarine Fleet that provides enhanced Anti- Submarine Warfare (ASW) and Anti-Torpedo Torpedo (ATT) mission capabilities. The CRAW development program leverages torpedo hardware developed by the Anti-Torpedo Torpedo Defense System (ATTDS) program and very-lightweight torpedo technologies developed by ONR. Two incremental Technology Insertions (TIs), TI-1 (hardware limited) and TI-2, will be used to deliver developmental prototypes to support Engineering, Development, and Operational Testing. The CRAW TI-1 effort is being executed as a Middle Tier of Acquisition (MTA) effort and will rapidly develop fieldable prototypes to demonstrate the new very-lightweight torpedo ASW capabilities in an operational environment and provide for a residual operational capability. The residual operational capability will, however, have a limited inventory of TI-1 systems. The TI-2 effort will update the TI-1 baseline to address obsolescence and improve producibility and supportability to enable production of additional inventory so that the CRAW capability can be fielded broadly across the submarine force. The TI-2 program is being executed as a Major Capability Acquisition Program and in FY24 will be initiated as a post-Milestone B (MS-B) ACAT III program. The TI-2 program is being phased with the TI-1 effort so that the TI-2 program can fully leverage the TI-1 prototypes as proof of design hardware. This will reduce overall cost of the TI-2 program as the TI-2 program will move immediately into development of proof of manufacturing prototypes to support Development Testing that will begin in FY26. Low Rate Initial Production (LRIP) units to support Operational Testing beginning in FY29 will also be delivered as part of TI-2. The CRAW program also includes development of launcher system modifications to allow for launch capabilities from vertical and horizontal launch tubes. This will include the development of the Revolver Multi-Payload horizontal launcher system that enables launch of multiple very-lightweight torpedoes from standard submarine torpedo tubes. Project 1268 Non-Traditional Acoustic Communications (NTAC) NTAC provides advanced undersea acoustic communications across multiple platforms within the Navy. This program builds upon the baseline NTAC software capability and integrates the software components into existing hardware to expand the effectiveness and reliability of the capability. Additional details are available at the classified level. Submarine Launch Unmanned Aerial System (SLUAS) funds transfer from RDTEN PE 0604562N beginning in FY25. SLUAS incorporates unmanned aerial vehicles, vehicle encapsulating canisters, vehicle command and control capabilities, and vehicle stowage into submarines. SLUAS extends the sensor range of the submarine, serving as a key enabler of Over-The-Horizon (OTH) weapons employment. The SAWS Development Program transitions the research and development of new technologies and capabilities generated under the Future Naval Capabilities (FNC), Small Business and Innovative Research (SBIR), and other Research, Development, Test & Evaluation (RDT&E) initiatives. Hardware and software evaluations in representative acoustic environments, against projected threats utilizing digital and hardware-in-the-loop simulations determines the effectiveness and impact on improving submarine survivability. The technology is then integrated into the appropriate product line. Additionally, this effort also includes advanced studies, product development and improvements for Submarine Acoustic Warfare Systems (SAWS) including but not limited to AASP, CSA, SubTDS, CRAW and NTAC.
