General Dynamics Mission Systems awarded SSBN follow-on contract
General Dynamics Mission Systems has received a follow-on, omnibus contract from the US Navy for fire control systems and subsystems aboard US Navy and UK Royal Navy nuclear ballistic-missile submarines (SSBN).
The contract, which has a total potential value of $299.8 million over the next four years, is a follow-on to a contract awarded to General Dynamics in December 2015 for the development, production, installation and deployed-systems support of US and UK Trident II submarine strategic weapons systems and subsystems.
The company’s Maritime and Strategic Systems line of business will deliver support and modernisation of the existing SSBN strategic weapon system including fire control subsystem installation, maintenance, sustainment, training and repairs to navigation and launch subsystems.
The company will also continue development of the fire control system for the US Navy’s Columbia class submarine and the Royal Navy’s Dreadnought class ballistic-missile submarine.
Work on the development and sustainment of the US Navy’s Ohio class guided-missile submarine attack weapon control system is also part of the contract.
