Ohio-Class Submarines
Guided and Ballistic Missile Submarines
The Ohio-class submarines are the backbone of the U.S. Navy's strategic deterrence force. General Dynamics Mission Systems is responsible for the Ohio-class submarines' combat system, strategic weapon systems and subsystems.
From guided torpedos to Trident II Fire Control Systems, General Dynamics Mission Systems supports the Ohio-class submarines' weapons and combat systems. Today, we're modernizing these submarines to make them even smarter.
About The Ohio-Class
General Dynamics Electric Boat is the prime contractor for the U.S. Navy's Ohio-class submarines. The Ohio-class consists of 14 ballistic missile submarines and 4 guided missile submarines.
The Ohio-class Ballistic Missile Submarines (SSBN) are designed for stealth and carry the Trident II ballistic missile. These submarines can conduct extended strategic deterrence patrols across the ocean.
The Ohio-class Guided Missile Submarines (SSGN) can carry more than 150 Tomahawk Cruise Missiles. They can also carry Special Operations Forces teams which are able to be deployed through a special hatch and boat. Due to their versatility, SSGNs are used as test beds for new technologies and operational concepts.
The Ohio-class SSBN submarines are scheduled to be replaced by the Columbia-class SSBN submarines, which are currently under construction.
AN/BYG-1 Combat System
Progeny Systems, a General Dynamics Mission Systems business area, supports the AN/BYG-1 combat system. The AN/BYG-1 combat system integrates the Tactical Control System (TCS), Weapons/Payload Control System (PCS), information assurance and tactical network subsystems onboard the Ohio-class submarines.
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.
The Payload Control System (PCS) provides planning, command and control, and launch control of all submarine payloads, including torpedoes, missiles, unmanned vehicles, and countermeasures.
Fire Control System
General Dynamics developed and supports the most reliable fire control systems in the Navy’s inventory – those of the Ohio-class ballistic missile submarines (SSBNs). We are modernizing the Ohio-class' Trident II strategic weapon system including fire control subsystem installation, maintenance, sustainment, training and repairs to navigation and launch subsystems.
The Trident II is a Submarine Launched Ballistic Missile (SLBM) with a range of 4,000 miles. General Dynamics has designed, produced, installed, and sustained every version of the Fire Control System and guidance systems for Polaris, Poseidon, Trident I and Trident II missiles for more than 65 years.
SONAR Systems
Our SONAR systems support the Ohio-class submarine’s active and passive systems including acoustic transmit capabilities, target and weapon tracking, underwater communication, and data collection.
The Acoustic Intercept & Ranging (AI&R) is an advanced real-time processing solution integrated into the SONAR systems of every U.S. Navy submarine and is designed to autonomously detect underwater acoustic emissions.
The Transmit Group (TG) hardware consists of processing cabinets, analog power amplifiers, and SONAR interfaces and enable acoustic transmit capabilities such as underwater communication, active sonar, ice draft detection, and depth sounding.
Guided Missile Submarine (SSGN) Conversion
General Dynamics Mission Systems played a lead role in the Navy's conversion of four Ohio-Class ballistic missile submarines, the USS Ohio, USS Michigan, USS Florida and USS Georgia, into guided missile submarines. These guided missile submarines (SSGN), with their ability to carry a large Special Operations Force, coupled with their Tomahawk strike capability and inherent stealth characteristics, embody a new level of adaptable warfare.
General Dynamics developed the launch control system for the 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.
Columbia-Class: U.S. NAVY'S NEXT GENERATION SSBN
The Columbia-class is the U.S. Navy's next generation ballistic missile submarine program, which will replace the Ohio-class ballistic missile submarines. General Dynamics Mission Systems is responsible for the Columbia-class submarine’s strategic weapons systems and subsystems.
