◆ Scaling +140%
HitchAI read

U.S. Navy funding ramps 140% to a $114.3M request in FY2027. In the FY2027 defense authorization, the House funded it in full; the Senate funded it in full; House appropriators added 6.5% (to $121.7M). RTX / Raytheon leads the industry work, though an unusually large share flows to government labs and warfare centers.

Program detail

Mission & acquisition strategy

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 Submarine Torpedo Defensive Systems (SubTDS) (MK 5 and MK 6), Submarine Tethered Expendable Buoy (STEB), Compact Rapid Attack Weapon (CRAW), Non-Traditional Acoustic Communications (NTAC), and Submarine Launched Unmanned Aerial System (SLUAS).

The CRAW acquisition strategy is to use two incremental Technology Insertions (TIs) to deliver a new submarine launched very-lightweight torpedo capability. 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. A competitive industry development OTA for CRAW TI-2 was awarded in FY 2022 to Raytheon (Prime Contractor) to establish a manufacturable CRAW design baseline. The CRAW operational software will be developed by PSU-ARL.

What project 1267 buys

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 hardware Technology Insertions (TIs), TI-1 and TI-2, will be used to deliver developmental prototypes to support Engineering, Development, and Operational Testing. The ASW and ATT capabilities will be delivered via two Advanced Processor Build (APB) software spirals. The ASW capability will be part of APB-1 and the ATT capability will be included in APB-2. 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. 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 post-Milestone B, ACAT III Major Capability Acquisition 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. LRIP units to support Operational Testing will also be delivered as part of TI-2. CRAW RDT&E funding also supports submarine launcher system upgrades and integration. Launcher system modifications will include development of launch capabilities from vertical and horizontal launch tubes. This includes the development of the Revolver launcher system that enables launch of multiple very-lightweight torpedoes from standard submarine torpedo tubes. 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, inform any refinement of hardware, and inform assessments of technical risks.

What project 1265 buys

Project 1265 SubTDS The first effort of the overall SubTDS program focuses on delivering full ICL functionality to all submarines in the fleet via the ADC MK5 effort. The ADC MK5 incorporates new adaptive technologies in a three-inch diameter form factor and will evolve through software/hardware upgrades, improved mobility, combat control system integration via ICL, and enhanced functionality to counter advancing torpedo threats. ADC MK6 effort focuses on developing an ECL hosted 6-inch acoustic countermeasure to supersede the ADC MK3. PMS415 STEB effort is limited to the development of changes to the ICL, specifically the breech door, to provide a stand-alone power and communications capability to the payload through the ICL via a TEMPALT, with funding ending in FY 2026.
