Submarine Acoustic War Dev
Abstract
The Submarine Acoustic Warfare (SAWS) Development Program includes Submarine Torpedo Defense System (SubTDS), Compact Rapid Attack Weapon (CRAW) and Non-Traditional Acoustic Communications (NTAC). The SAWS Development Programs improve the survivability of all U.S. Submarines. The SubTDS efforts include acoustic countermeasures, submarine defense capabilities, external launch systems, all acoustic augmentation systems for the U.S. Navy submarines and Undersea Defense Working Group (UDWG). In FY21 SubTDS begins development testing of ADC MK5 EDM-1 countermeasure variants. The Compact Rapid Attack Weapon (CRAW) and Non-Traditional Acoustic Communications (NTAC) efforts begin in FY21. Project 1265 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 providing the Acoustic Device Countermeasure (ADC) MK5 capability to all submarines in the fleet. The ADC MK5 development will result in 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. FY20 funding supports on-going SubTDS development including component and subsystem design, in support of the ADC MK5 Preliminary Design Review. FY21 funding will provide for completion of the Critical Design Review and procurement of multiple ADC MK5 EDM countermeasure variants, which includes four (4) Countermeasure Control Tools (CCT), Sonar Test Units ((4) STU-E's, (4) STU-A's), and seventeen (17) EDM-1 devices that are recoverable, rechargeable, and reusable. FY21 will include in water developmental testing at test facilities, test lakes and at sea from US Navy surface ships. EDM-2 development and prototyping will begin in preparation for FY22 deliveries. 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 FY24. FY 2021 funding for SubTDS will continue the development, mature the capability, and deliver multiple Engineering Development Models for supporting contractor and government testing. 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 can double as a submarine hard kill countermeasure. The Office of Naval Research (ONR) developed the initial CRAW design to be a multi-platform and multi-mission weapon. This program will finish design gaps in the CRAW hardware and transition the technology into a production ready design. In addition, it will mature the software currently in development under an ONR Future Naval Capability (FNC) program and transition it into CRAW baseline system. The program will establish a baseline production design, incrementally improve software through Advanced Processor Build (APB) software upgrades, test and qualify the system for safe operations, and stand-up a production line to achieve full rate production. 2. Compact Rapid Attack Weapon (CRAW) Submarine Integration Integration of CRAW into the external countermeasure launcher (ECL) assembly and the upgrades to the combat systems supports pre-planning and launch control of the CRAW. 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, Countermeasure Set Acoustic (CSA) launcher, BYG-1 combat system, and Common Weapon Launcher (CWL). The upgrades will come in two initial phases with a Tactical Temporary Alteration (TEMPALT) to Technical Insertion 20 (TI-20) for installation of capability on Virginia (VA) Block (BLK) III/IV ships in FY24, and then a permanent Ship Alteration (SHIPALT) in TI-24 for all VA class hulls. 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 post installation. 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.
