AN/BYG-1 Submarine Tactical
Control System (TCS)
Delivering Open System Flexibility for
Rapid Technology Insertion
The AN/BYG-1 modernization program develops commercial-off-the-shelf (COTS)
based software and hardware upgrades to integrate improved tactical and weapons
control capabilities for multiple submarine classes.
Development of the tactical control system (TCS) portion of the system is separated
from the weapons control system (WCS), allowing independent yet parallel
development and certification of TCS and WCS. The AN/BYG-1 integrates the tactical
control, weapons control, and tactical network subsystems. Each of these systems
incorporates a variety of advanced process build (APB) software algorithms that are
developed by a host of industry, government and academia sources. The AN/BYG-
1 is installed on the U.S. Navy’s Los Angeles, Seawolf, Virginia, and SSGN-class
submarines, as well as on the Royal Australian Navy’s Collins-class submarines.
TCS Leads the Implementation of the Navy’s Open Source
Initiative on Submarines
The TCS portion of BYG-1 integrates sensor inputs to provide a common operational
picture and improved situational awareness in an information assurance (IA) compliant
environment that exploits the power of sonar, electronic support measures, radar,
navigation, periscopes, and communication. The result is a constantly updated
tactical picture providing the commanding officer and his crew with the knowledge
they require to most effectively operate their ship. The system was designed
using commercial off the shelf (COTS) equipment and open standards that provide

interoperability, portability, scalability, and supplier independence for all hardware and
software components. The TCS system architecture allows for rapid COTS insertion
to accommodate and integrate additional functionality and sensors.
Open Software & Collaborative Development
General Dynamics develops TCS in a collaborative environment with over 50% of the
development effort performed by small businesses, leveraging the best solutions
that industry, government and academia can offer. Potential system enhancements
and new fleet capabilities are evaluated for inclusion in the system on a biennial basis
as part of the Navy’s Advanced Processing Builds (APB) software development and
fielding process. Hardware upgrades (Technology Insertions or TI’s) are developed on
a biennial basis to provide improved capability and to address COTS obsolescence.
General Dynamics’ use of an extensible architecture maximizes the use of Open
Source technology and readily incorporates capability improvements and hardware
upgrades. Utilizing COTS based software and hardware in a well documented and
published open architecture framework, General Dynamics Advanced Information
Systems executes the TCS integration program in an “Open Business” model
environment, adhering to the principles of the Navy’s Open Source Initiative. All
TCS developed software and information is provided openly and freely to the TCS
development community of contractors, laboratories, and universities as well as any
other Department of Defense related organization that the Navy desires. Equally
important, throughout each development and integration cycle, the software and
system design information is provided frequently at set increments, allowing for
frequent evaluation and testing by the end user.
Collaborative Development Environment
Directly linked with the Open Source initiatives is the establishment of a Collaborative
Development Environment (CDE) to support not only the development of the system
level software but also to provide an environment that allows other users and
developers access to comprehensive system and interface stimulation capabilities to
emulate real world environments. The TCS CDE offers a secure web site providing
access to the entire classified and unclassified TCS information database ensuring
continuous flow of information between all participants.
New System Capabilities
The initial fielding of TCS completed the separation of BYG-1’s tactical control
from weapons control. This allows rapid fielding of enhancements to TCS without
requiring changes and recertification of weapons control, saving both time and money
compared with implementing changes in a traditional Combat System. Previous
system enhancements have included improved Commanding Officer situational
awareness through implementation of display sharing across subsystem boundaries
and incorporation of innovative design changes to manage and distribute critical
navigation data elements. Enhancements planned for 2011 include integration of
unmanned air vehicle (UAV) command and control (C2) and modernization to high
definition displays.

A History of Weapon
System Integration
As the integrator for both the BYG-
1’s TCS as well as the Weapons
Control System, General Dynamics
has once again demonstrated its
leadership in providing innovative
integration approaches to deliver
cost effective solutions to the
submarine force. General Dynamics
developed the most reliable
COTS-based fire control systems
in the Navy’s inventory – those
of the Ohio-class ballistic missile
submarines (SSBNs), as well as
the Tomahawk Weapon Control
System on SSGN – and has applied
its expertise and experience to
the AN/BYG-1 System. On TCS,
General Dynamics has provided the
business and technical framework
needed for providing Team
Submarine innovation, flexibility,
and responsiveness so that the best
capability reaches the Fleet rapidly.
