The vertical scale does not start at zero: the baseline sits just below this program’s smallest year, so a low point on this line is not a small amount. Read the shape for direction and the grid below for the figures.

Asked vs spent: the PB2024 book requested $133.1M for FY2024; the PB2026 book reported $144.0M as actual total obligation authority — $10.9M above the request. 144.0 − 133.1 = 10.9 USD millions — the compact figures above are rounded for reading.

Description
Description — SSN Combat Control Systems
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 counter measures, and other payload capabilities. 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, TI-26, 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. As a result of this interdependency, AN/BYG-1 installations must be performed in conjunction with the installations of the other SWFTS systems. VB011 - COMBAT SYSTEMS TECHNOLOGY REFRESH / LEGACY INTEGRATION Procures Engineering Changes (EC) and Ordnance Alterations (ORDALT) to correct fleet reported problems with fielded AN/BYG-1 software and hardware. Procures Weapons Launch Systems and training systems, including the Multi-tube Weapon Simulator (MTWS) and the Onboard Team Trainer. Provides system engineering in support of TacLAN, and Cybersecurity for AN/BYG-1 authorization and accreditation. Procures Infrastructure COTS H/W in order to enable faster delivery, installation, and updating of developed systems to the warfighter by creating a cyber-resilient environment that links the system developers to the fielded systems. Procures TIH Modernization hardware to allow flexible, efficient utilization of the fielded computing systems, providing the opportunity for dynamic response and recovery when the system is under cyber-attack, and positioning SWFTS to leverage the developing fields of Artificial Intelligence and Machine Learning. VB034 - SUBMARINE COMBAT CONTROL SYSTEM MODERNIZATION PROGRAM Procures hardware and software upgrades for AN/BYG-1 system for installation on all submarine platforms. Efforts include pre-production, design, hardware production, and integration. Funds are for the installation of Combat Control System equipment included in the Fleet Modernization Program. VB800 - ELECTRONIC CHARTING DISPLAY INFORMATION SYSTEM Procures the Submarine Electronic Charting Display Information System - Navy ECDIS on all U.S. Navy submarine platforms. PEO UWS Submarine Combat and Weapons Control Program Office has program acquisition, contractual, financial, engineering and logistical responsibilities for submarine Navy ECDIS systems. This includes conducting submarine Navy ECDIS integration, integration testing, NAVCERT, and fielding responsibilities in support of all baselines. VB995 - PRODUCTION ENGINEERING AND INITIAL TRAINING Procures production and logistics support, assistance for asset management, cost analyses, preparation of contract specifications, monitoring of contract deliverables, contractor cost, schedule and performance monitoring, Integrated Logistics Support (ILS) planning and Government Furnished Information (GFI) coordination. Also provides initial training curriculum development, training management materials, exercise control group development, and pilot services to the Fleet. VB997 - SSGN SUSTAINING SUPPORT Provides funding to the Strategic Systems Program (SSP) in support of the Equipment procurement, installation and sustainment required for the life-cycle operational support of SSGN Attack Weapons Systems (AWS) currently on four OHIO-class SSGNs. Funding provides the end-of-life technical refresh of critical components and maintain cyber security posture for to the Attack Weapon Control System (AWCS) and the Attack Weapons System Interface Simulator (AWIS). AWCS technical refresh includes Training Mode Enhancements and updates to Maintenance Interface Network requires an update to the operating system to maintain Missile Technician training on board the SSGN. Funding ended in FY25. VB700 - PAYLOAD PROCUREMENT Procurement of payloads to include Unmanned Aerial System (UAS) vehicles for integration, verification, and validation. Procurement entails integrated, modified, and tested horizontally and vertically deployed payloads. SLUAS transferred to OPN Line Item 2210 in FY25.
Justification
Justification — SSN Combat Control Systems
FY 2026 funding supports the procurement of shipsets, and installations of shipsets procured in FY 2025. Specifically, FY 2026 procures one (1) SSBN COLUMBIA Class, two (2) SSBN OHIO Class, three (3) SSN 774 Class, and one (1) SSN 774 Class w/ CWL. The FY 2026 request was reduced by $19.832 million for Advisory and Assistance Services to promote efficiencies and advance the policies of the Administration in alignment with Executive Order 14222, "Implementing the President's Department of Government Efficiency Cost Efficiency Initiative." Combat Control System funding is used for planning, material procurement, and installation efforts to modernize the Submarine Fleet, meet DoD priorities - Virginia-class Submarines and Priority Critical Cybersecurity, increase lethality, match threats to capabilities, and increase operational availability. The AN/BYG-1 Combat Control System is linked and aligned with the other Submarine Warfare Federated Tactical Systems (SWFTS); Acoustic Rapid Commercial Off-the-Shelf (COTS) Insertion (ARCI) Sonar System, AN/BVY-1 Integrated Submarine Imaging System (ISIS) and AN/BLQ-10 Electronic Warfare (EW) System. These SWFTS (PMS 401, PMS 425, PMS 435) systems must be procured and installed in like quantities.

Contractor concentration
No concentration index is published for this line. This line's high-confidence links do not clear the floor for a published concentration index — at least 3 awards across 2 contractor families holding positive obligations, with positive net linked dollars. An index below that floor is a fact about the sample, not about the market. Whatever further links this line carries are medium-confidence, and what each medium evidence path does and does not establish is set out in the methodology. Both bases are in the downloadable warehouse.
Lobbying mentions
