Allard Nazarian's (ANG) Granite State Manufacturing (GSM) has received a contract from UTC Aerospace Systems to provide advanced integrated low-pressure electrolyzer (AILPE) frame assemblies for the Block IV Virginia-class submarine programme.
Under this contract, GSM will work with UTC Aerospace to build the AILPE frame assemblies, and is expected to deliver one frame assembly unit every six months through 2018.
ANG chairman and CEO John Allard said: "GSM is honoured to continue our work in support of the US Navy and is pleased to work with UTC Aerospace Systems to provide these innovative and life-critical unit assemblies.
"We look forward to completing these components for the Block IV Virginia-class submarine and working together to develop solutions for UTC Aerospace Systems and the submarine fleet."
Meanwhile, GSM also produces multiple other systems for the Block IV Virginia-class Submarine programme, the company stated.
In May, UTC Aerospace Systems secured an order form Newport News Shipbuilding to deliver a number of composite components for the US Navy's next ten Virginia-class nuclear attack submarines.
Under the contract, UTC will supply the composite components, including the bow dome and rubber boot, along with a variety of external fairing structures.
The new Virginia-class attack submarine, collectively referred to as Block IV, is an advanced stealth multi-mission nuclear-powered submarine for deep-ocean, anti-submarine warfare and littoral operations.
The vessels are equipped with 12 vertical missile launch tubes and four 533mm torpedo tubes. The vertical launching system has the capacity to launch 16 Tomahawk submarine-launched cruise missiles in a single salvo.
