Compact Rapid Attack Weapon (CRAW)

Abstract

Within the CRAW Project line 1267, funding remains level from FY24 to FY25. The FY25 budget supports $10M in procurement of remaining material for TI-2 hardware material and integration and testing of EDMs 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 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 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 TI-1 effort will rapidly deliver an ASW capability at a reduced cost by leveraging hardware from the ATTDS program and technologies developed by ONR. The ATTDS program developed a very-lightweight torpedo that can be launched from a surface ship. The hardware design from ATTDS will be modified for submarine integration and use as an ASW weapon. Very-lightweight torpedo technologies developed by ONR will be significantly leveraged and transitioned into CRAW. Funding for the TI-1 effort supports development of ASW software, warhead design and certification, upgrades to the torpedo power plant, combat control system modifications, submarine launcher system modification, and overall system integration. Launcher system modifications will include development of launch capabilities from vertical and horizontal launch tubes. This will include the development of the Revolver Multi-Payload launcher system that enables launch of multiple very-lightweight torpedoes from standard submarine torpedo tubes. The TI-1 effort will rapidly develop a fieldable system with prototype very-lightweight torpedoes that will be demonstrated in an operationally relevant environment in FY26. After the demonstration, the TI-1 system will constitute a residual operational capability. The TI-2 program will develop and deliver proof of manufacturing prototypes that will be used to reduce risk associated with starting manufacturing and production of new very-lightweight torpedoes. The TI-2 prototypes will support Development Testing to collect data on performance and inform any refinement of hardware and inform assessments of technical risks. As part of the TI-2 program, manufacturing and assembly procedures will be refined to improve producibility, qualification testing will be completed, an ATT software upgrade will be developed, any hardware obsolescence will be addressed, and Development Testing and Operational Testing will be conducted. CRAW TI-2 long lead material is being procured in FY24 to support torpedo delivery in FY26. ATT software development will begin in FY25. Development of modeling and simulation capabilities to improve development timelines and reduce testing and evaluation cost and schedule will continue in FY25. Qualification testing and Developmental Testing will begin in FY26. Acquisition Milestone C (M.S. C) will be completed in FY28 to support procurement of Low-Rate Initial Production very-lightweight torpedoes. Operational Testing will begin in FY29 and continuing in FY30.
