Philly Shipyard has secured another US government contract.

The Pennsylvania yard will make repairs to the government-owned 33,640-dwt ro-ro USNS Charlton (built 2000), having secured a contract from Patriot Contract Services.

The USNS Charlton is part of the US Navy's Military Sealift Command and carries tanks, armoured personnel carriers, tractor-trailers and other equipment and supplies to conflict areas worldwide.

"This is a great win for our shipyard and demonstrates our ability to acquire substantial repair jobs going forward," president and chief executive Steinar Nerbovik said.
