BWX Technologies (BWXT) has been contracted to support the manufacture of naval nuclear reactor components for the US Navy's submarines and aircraft carriers.
Awarded under the US Naval Reactors Program, the contracts worth approximately $34.5m will be carried out by BWXT Nuclear Operations Group.
Of the total funding, nearly $9.4m will represent the exercise of options under a previously announced contract, and approximately $25.1m represents new contracts awarded to the company this year.
BWXT president and chief executive officer Peyton S Baker said: "We are very pleased to receive these contract awards and add to our backlog of work.
"We continue to stay focused on operating safely and delivering the quality products that our customer demands."
Work under the contracts will be carried out at the company's US facilities in Lynchburg, Virginia; Barberton, Ohio; and Mount Vernon, Indiana.
According to the company, activities related to the contracts have already started and the majority of work is expected to be performed over the next two years.
Since the 1950s, BWXT has been the manufacturer of naval nuclear reactors for submarines and aircraft carriers.
BWXT reactors power the US Navy's Ohio, Virginia, Seawolf and Los Angeles-class submarines, as well as the Nimitz and Ford-class aircraft carriers.
The company designed and fabricated components for the USS Nautilus, which is the world's first nuclear-powered submarine.
