Progeny Systems Logo

Progeny Systems is a business area within General Dynamics Mission Systems that provides numerous mission-critical capabilities and products for our Submarine and Surface Navies. Progeny Systems is the systems integrator for AN/BYG-1 Submarine Combat System hardware and software, which contains a number of critical major subsystems, also developed by Progeny Systems.


What is AN/BYG-1?

AN/BYG-1 is an open-architecture submarine combat control system that integrates tactical control, payload and weapons control, information assurance, and a number of smaller subsystems and applications. Sailors interact with this system through multiple operator displays, which are installed on the U.S. Navy's Virginia, Los Angeles, Ohio, Columbia, and Seawolf-class submarines as well as the Australian RAN Collins-class submarine. The integrated AN/BYG-1 system provides the submarine force with the ability to conduct a wide range of missions including Anti-Submarine Warfare (ASW), Anti-Surface Warfare (ASUW), Strike, and Intelligence, Surveillance and Reconnaissance (ISR).

AN/BYG-1 Capabilities

  • Utilizes ruggedized Commercial Off-The-Shelf (COTS) computer hardware and software that are amenable to rapid technology insertion updates.
  • Provides detailed operator displays for contact management, payload command and control, threat warning, mission tasking, geographic environment, signal alerts, analysis, and reports.
  • Analyzes submarine sensor data to track submarine and surface vessels.
  • Employs heavyweight torpedoes against submarine and surface ship targets.
  • Receives strike warfare tasking, plans strike missions, and employs Tomahawk cruise missiles against various targets.
  • Receives and synthesizes all sensor data and external tactical intelligence to produce an integrated tactical picture.

AN/BYG-1 Subsystems

General Dynamics Mission Systems' Progeny Systems develops and provides major subsystem capabilities for the integrated AN/BYG-1 Combat Control System.

Tactical Control System (TCS)

The Tactical Control System (TCS) ingests data from the submarine’s sensor and communication systems to provide a common operational picture. TCS provides sensor data fusion, target motion analysis, tactical situational awareness, and command decision tools to enable the watch standers and commanding officers to execute their mission.

Payload Control System (PCS)

The Payload Control System (PCS) provides planning, command and control, and launch control of all submarine payloads. These payloads include torpedoes, missiles, unmanned vehicles, and countermeasures. PCS was rearchitected from the historic Weapons Control System (WCS) to enable rapid integration of current and future payloads as well as payload updates.

Information Assurance (IA)

Whether underway or in port, keeping our submarines secure from cyber threats is paramount. From user permissions to intrusion detection, Progeny Systems' cybersecurity software is multi-level, customizable, and robust. In addition to our deployed cyber capabilities, we focus our cyber research and development efforts to continuously develop solutions to counter ever-evolving threats.
