Submarine Tactical Warfare System
Abstract
The AN/BYG-1 is the combat control system common across all submarine platforms which incorporates tactical control, weapon/payload control and Tactical Local Area Network (TacLAN) functions into a single procurement program. AN/BYG-1 allows the submarine to rapidly update the ship-safety tactical picture, integrates the common tactical picture into the battlegroup, improves torpedo interfaces, and provides tactical TOMAHAWK, Harpoon, and future payload capability. AN/BYG-1 systems will be continuously updated with hardware enhancements to address Commercial Off The Shelf (COTS) obsolescence and provide capability improvements through software upgrades. Hardware updates are referred to as Tech Insertion (TI) kits and are differentiated by year of development (i.e. TI-20, TI-22, TI-24, etc.). The TI upgrades provide the baseline for all future AN/BYG-1 procurements. AN/BYG-1 is part of the Submarine Warfare Federated Tactical Systems (SWFTS), a family of interdependent systems that conduct cooperative system development and installations. Project Unit 0236: This program develops Commercial-Off-The-Shelf (COTS) based software and hardware upgrades for AN/BYG-1, the Multi-tube Weapons Simulator (MTWS), and the Common Weapon Launcher (CWL) in order to integrate improved tactical and payload control capabilities for all submarine classes. SLUAS incorporates unmanned aerial vehicles, vehicle encapsulating canisters, vehicle command and control capabilities, and vehicle stowage into submarines. SLUAS extends the sensor range of the submarine, serving as a key enabler of Over-The-Horizon (OTH) weapons employment. SLUAS transfers to RDTEN Program Element (PE) 0101226N beginning in FY25. Provides funding for the development of Legacy Launchers; MTWS; Information Assurance system; Onboard Team Trainer (OBTT); and Common Infrastructure Services (CIS) subsystem. This includes integration of OBTT - Master Controller (OBTT - MC) & Inter-Subsystem Monitoring Tool (ISMT) efforts as well as other common services within SWFTS. FY25 continues funding for development of TI-24 and TI-26. Cybersecurity efforts continue to grow due to increasing interconnection complexity, more Internet Protocol based traffic in future baselines, and development of Cyber Safe Controls. Integration efforts for additional submarine payloads including MK48 ADCAP variants APB 6, APB 7 and Maritime Strike Tomahawk (MST) continue in FY25. FY25 also continues efforts to support classified payloads.

- Change Summary Explanation
- FY 2023 reduction of $1.274 million in support of SBIR. The overall FY25 funding was increased by $0.952 million to account for increased payload integration costs resulting from an increase in the cost of sustaining already fielded submarine payloads. FY2025 was reduced by $0.007 million for NWCF Rate Adjustment, $0.593 million for CIVPERS reductions and $0.265 million for Miscellaneous Adjustments. Submarine Launch Unmanned Aerial System (SLUAS) will transfer to RDTEN Program Element (PE) 0101226N beginning in FY25.
