Submarine Acoustic War Dev

Abstract

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 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 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 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 support on- going development including component and subsystem design, in support of the Preliminary Design Review (PDR), Critical Design Review (CDR) and procurement contract award of multiple ADC MK5 EDM countermeasure developmental variants. FY23 funding will complete the Critical Design Review (CDR) and deliver four (4) Countermeasure Control Tools (CCT) and four (4) Sonar Test Units (STU- E). Hardware in the Loop Testing (HWIL) in the Environment Centric Weapons Analysis Facility (EC WAF) on STU-E will begin in FY23. EDM-2 production prototyping will continue in preparation for beginning deliveries in FY24. 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 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. The next development in the SubTDS program (Increment 2) focuses on the development of the External Countermeasure Launcher (ECL) hosted 6-inch acoustic countermeasure, Tactical Decision Aid, and integration with ship systems for to provide improved adaptive capabilities leading up to a contract 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) 1. Compact Rapid Attack Weapon (CRAW) Development Design CRAW is a very lightweight torpedo that will have Anti-Submarine Warfare (ASW) and Anti-Torpedo Torpedo (ATT) capabilities. ONR began a follow-on FNC in FY20 to demonstrate the ability to modify a previous design for submarine integration and use as an ASW weapon via TEMPALT in FY24. PMS415 began a Rapid Prototyping (RP) Middle Tier Acquisition (MTA) in FY22 to transition the ONR FNC effort to a lasting Early Operational Capability via a SHIPALT in FY26. The ONR FNC and CRAW MTA program received forty (40) plus existing legacy hardware devices that will be updated for submarine integration, and will be known as the CRAW TI-1 hardware baseline. The critical updates consist of integrating a new Safe and Arming (S&A) and Warhead (WH) design, and the development of Anti-Submarine Warfare (ASW) mission software. PSU/ARL will support the ONR FNC demonstration, the development of the CRAW TI-1 hardware and software updates, and the maturation of the design into a permanent capability through the RP MTA approach. Leveraging the existing legacy hardware devices and the long standing technological knowledge of PSU/ARL for designing, testing, and qualifying the CRAW device will enable the program to deliver the leave behind residual capability in FY26 as the TI-1/ASW Early Operational Capability (EOC). The program will then transition the RP MTA into a Major Capability Acquisition Program that will update the TI-1 baseline into a supportable and producible industry design that will be known as the TI-2 hardware baseline. PMS415 awarded a UTIC OTA contract in FY22 to Raytheon (Prime Contractor) who will work with ARL/PSU in FY23 to transfer knowledge and begin initial TI-2 baseline development. In FY24, Raytheon will be developing the TI-2 hardware and procuring long lead material that will address obsolescence issues, develop the production line, improve manufacturing processes, stand-up the vendor base, and deliver TI-2 EDMs in support of future full-rate production. PMS415 intends to formally initiate the TI-2 program of record in FY23 as a post MS-B ACAT III program. The program is planning to reach MS-C in FY28. 2. Compact Rapid Attack Weapon (CRAW) Submarine Integration Submarine integration of CRAW into the external countermeasure launcher (ECL) assembly requires upgrades to the combat systems in support of pre-planning and launch control of the CRAW, a new launch tube assembly that fits into the ECL, and ship alteration and modernization planning documents. This effort requires upgrades to the submarine combat system as a part of the Submarine Federated and Warfare Tactical Systems (SWFTS) modernization cycle. The major components requiring hardware and software upgrades to support CRAW include the ECL assembly, BYG-1 combat system, and Common Weapon Launcher (CWL). The upgrades will come in two initial phases with a Temporary Alteration (TEMPALT) for the ONR FNC demonstration launch from a Virginia Class Submarine (VCS), and then a permanent Ship Alteration (SHIPALT) to TI-24 for VCS Blk III and later hulls as a part of the Rapid Prototyping MTA. In addition, the necessary TEMPALT and SHIPALT documentation (e.g., design changes, safety reports, test reports, etc.) required for installation aboard a submarine will be developed. An integrated test program and operational testing with the Navy's Command Operational Test and Evaluation Force will be conducted after installation of the TI-24 SHIPALT. In FY2024 the program will complete a TEMPALT data package and coordinate with ONR FNC to demonstrate the launch of a CRAW from an ECL on a submarine in FY24. This test will inform the final SHIPALT configuration needed for permanent integration and installation of CRAW on a submarine beginning in FY2026. The program will also continue development of upgrades necessary to support CRAW launch and control from the BYG-1 combat system. The program will also begin work with ONR on Revolver Multi Payload (MP) to enable CRAW launch and control via torpedo tubes. This has the potential to significantly reduce DT/OT duration by enabling the launch of test CRAWs from the torpedo room and thereby minimizing the time consuming replacement and reloading of ECL assemblies (which must be accomplished pier side with crane support). Project 1268 Non-Traditional Acoustic Communications (NTAC) This capability 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. 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.
