General Dynamics to maintain and update the combat system computers and software on board US Navy submarines

Washington – General Dynamics’ submarine electronics experts will maintain and modernize the US Navy’s AN / BYG-1 Submarine Combat System under the terms of a $15.9 million order announced Tuesday.

Officials with the Naval Naval Systems Command Washington of General Dynamics Mission Systems in Fairfax, Virginia, are requesting engineering services to design, integrate and test the AN/BYG-1 tactical control system.

General Dynamics upgrades the AN/BYG-1 submarine combat system with Commercial Off-the-shelf (COTS) Computers. The company replaces central processors with COTS computers, and updates ASS processors with new COTS technologies in periodic upgrades called technology introduction.

The AN/BYG-1 system is an analogue of the Navy’s Advanced Rapid COTS Insertion (A-RCI) software that uses COTS computers in marine sonar signal processing systems.

crews of submarines equipped with the AN / BYG-1 combat control system are able to analyze contact information with submarine sensors to track submarines and surface ships in the open ocean and coastal waters; aim and fire heavyweight torpedoes against enemy submarines and surface ships; Receive strike war orders, plan strike missions, and use Tomahawk missiles for ground attack; It receives and synthesizes sensor data and external tactical intelligence to produce an integrated tactical picture of situational awareness.

These upgrades are for combat systems and computers aboard ballistic missile submarines, cruise missile submarines, and fast attack submarines.

The AN/BYG-1 program includes a combat control system for Virginia-class attack submarines, as well as improved combat control systems for Los Angeles-class, Sea-Wolf-class attack submarines, ballistic missile submarines, and Ohio-class cruise missiles. General Dynamics is also offering AN/BYG-1 system upgrades to Australian Collins-class attack submarines.

The AN/BYG-1 modernization program separates the development of the Tactical Control System (TCS) and Weapons Control System (WCS) to enable independent, parallel development of these computer systems, General Dynamics officials say. Each of these systems uses a variety of software Algorithms developed by industry, government, and academia.

The TCS computer part of the BYG-1 integrates sensor inputs to provide a secure combined operational image and better situational awareness blending information sonar, electronic support measures, radar, navigation, binoculars and communications systems. The architecture of the TCS system allows for rapid COTS insertion to accommodate and integrate additional functions and sensors.

One advantage of rapid COTS technology upgrades to naval combat systems is the Navy’s ability to learn from real-world experience to make rapid improvements. The Navy’s recent recommendations, for example, have been to acquire automation technology to assist the operator in areas of high communication density.

Upon this request, General Dynamics will operate in Fairfax, Virginia, and should close by July 2023. For more information, contact General Dynamics Mission Systems online at https://gdmissionsystems.comor Naval Sea Systems Command in
