Compact Rapid Attack Weapon (CRAW)

Abstract

Compact Rapid Attack Weapon (CRAW) Development Design CRAW is a very lightweight torpedo that can double as an Anti-Submarine Warfare (ASW) and Anti-Torpedo Torpedo (ATT). The Office of Naval Research (ONR) developed the initial CRAW design to be a multi- platform and multi-mission weapon. This program will update the design for the submarine application 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 initially assemble units based upon the existing ONR design (TI-1), and then conduct a design spiral (TI-2) to address obsolescence issues and improve manufacturing necessary for production design. The program will transition and test the ASW software initially developed as part of the ONR FNC, and will develop and test ATT software capability for integration with TI-2 hardware builds. The program will test and qualify the integrated ASW/ATT system for safe operations, and stand-up a production line to achieve full rate production. 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, Countermeasure Set Acoustic (CSA) launcher, 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 Office of Naval Research (ONR) Future Naval Capabilities (FNC) demonstration launch from a Virginia Class Submarine in FY2023, and then a permanent Ship Alteration (SHIPALT) in TI-24 for VA Blk III/IV 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. In FY2022 the program will begin a non-tactical TEMPALT data package and demonstrate the launch of a CRAW from an ECL on a submarine in FY2023. This test will inform the final SHIPALT needed for early integration and install 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.
