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 Submarine Torpedo Defense System (SubTDS) 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 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 contract award for procurement of multiple ADC MK5 EDM countermeasure developmental variants. FY22 funding will procure four (4) Countermeasure Control Tools (CCT), and procure eight (8) Sonar Test Units ((4) STU-E's (4) STU's), and seventeen (17) EDM-1. FY23 will complete the Critical Design Review (CDR). FY23 will deliver eight (8) Sonar Test Units ((4) STU-E's (4) STU's), and seventeen (17) EDM-1. FY23 will include the Test Readiness Review (TRR) for STU and EDM-1 and in water developmental testing (DT) for these units. Hardware in the Loop Testing (HWIL) in the Environment Centric Weapons Analysis Facility (EC WAF) on STU-E will begin in FY23 EDM-2 development and production prototyping will continue in preparation for beginning production deliveries in FY24. The next development (Increment 2) effort focuses on the development of the External Countermeasure Launcher (ECL) 6-inch acoustic countermeasure, Tactical Decision Aid, and integration of communication interfaces with ship systems for enabling improved adaptive capabilities leading up to a contract award in FY26. 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 and 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. 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 FY23. 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 24 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 24 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 intends to execute this approach with the award of a UTIC OTA contract in Q3 FY22. In FY22 and early FY23, the awarded prime contractor will primarily shadow PSU/ARL to transition TI-1 CRAW knowledge and prepare for TI-2 development to begin in late FY23. The prime contractor 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 initiate the TI-2 program of record in mid to late FY23 as a post MS-B ACAT III program. The program is planning to reach MS-C in FY27. 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) to Technical Insertion 20 (TI-20) 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/IV 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 FY2023 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 FY23. 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 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 new 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.
