Transforming Legacy Submarines Into Flexible Launch Platforms

General Dynamics Mission Systems developed the launch control system for the U.S. Navy's guided missile submarines' (SSGN) large tubes and integrated the launch control system, the Tomahawk Weapon Control System, the Tomahawk Communications System and Mission Distribution System into the Attack Weapon Control System.

Our Open Architecture Framework

The SSGN weapon control system uses an open architecture framework, which lowers costs by allowing integration of new payloads and capabilities with minimal impacts to the overall system. By adapting industry electronic standards, the General Dynamics team was able to incorporate COTS components into the launch control system. The weapon system partitions functionality allowing the missile tube to accommodate launch functions specific to a new payload. A centralized launch controller coordinates launch of multiple payloads and resolves resource contentions. The architecture uses industry standard Internet Protocol and Ethernet to provide communications between the payload controller and tube interface electronics.

Integrating New Payloads

New encapsulation methods currently under development could allow SSGNs to carry a wide variety of payloads, from future littoral warfare weaponry to unmanned underwater or aerial vehicles. The SSGN Attack Weapon Control System architecture and open computing systems facilitate the insertion of these future capabilities and equipment into SSGNs. These same features support use of the SSGN as a test platform to develop future weapons, sensors and operational concepts. General Dynamics has proven capability to safely and effectively integrate existing weapon controllers with ship and launcher systems, resulting in new capabilities on an existing platform designed to use these capabilities when needed.

A History Of Reliable Systems

General Dynamics develops the most reliable fire control systems in the Navy’s inventory – those of the Ohio-class ballistic missile submarines (SSBNs) – and applies its expertise and experience to build an SSGN weapon control system that has the capability and flexibility to expand into future payloads. General Dynamics’ performance on these programs resulted in a record of accomplishment delivering highly reliable systems and software ahead of schedule and under budget.
