Under the $60m extended contract, the company will redesign interfaces that are critical to the navigation architectures spread over several submarine warfare federated tactical systems (SWFTS) across all the US navy submarine ship classes.
Lockheed Martin antisubmarine warfare (ASW) and integration programmes business development director Dave Boyle said: "Aligning innovation with the customer’s strategic plan is a key reason for our team’s track record of successfully integrating combat systems on both new construction and in-service submarines."
The company will also perform interface design changes on Virginia-class submarine construction.
In the past ten years, the SWFTS SE&I team has carried out engineering work to integrate several submarine combat subsystems, including sonar, imaging, BYG-1 (tactical control and weapons control), and communications, into one large system-of-systems for all in-service US Navy submarine combat systems.
Before installing on to the submarine, the team tests the combat system at its ASW lab in Manassas, Virginia, US, to ensure the subsystems correctly interface with each other.
The ASW lab is fully integrated with three of the major submarine combat systems, sonar, BYG-1 and imaging, and is open to all other SWFTS subsystems.
The US Navy’s Virginia-class attack nuclear submarine features stealth, sophisticated surveillance capabilities, and special warfare enhancements.
Over the last 40 years, Lockheed Martin has been supporting the US Navy’s submarines programme by offering solutions to complex systems, including navigation, sonar, and communications.
