Under the arrangement, BAE Systems will tandem dry-dock the USS Stethem (DDG 63) and USS Decatur (DDG 73) in October in their San Diego shipyard, a first for the facility.
The contract also features options that could raise the value up to US$185 million.
“The ability to simultaneously dock two DDGs is a special capability that BAE Systems brings to our Navy customer and comes at a critical time when additional throughput is necessary to meet surface combatant demands and modernisation requirements,” said David M. Thomas Jr, vice president and general manager of BAE Systems San Diego Ship Repair.
“Beyond the remarkable nature of this tandem docking, it will be business as usual for our shipyard team and partners given our significant experience working with the Arleigh Burke Class.”
Positioned end to end, the USS Stethem and USS Decatur will be lifted together inside BAE Systems’ “Pride of California” dry dock.
Installed in 2017, the Pride of California is 950-ft long, 160-ft wide and has a lifting capacity of 55,000 tonnes – making it the largest floating dry-dock in San Diego.
The destroyers each displace about 9,000 tonnes and are expected to be re-floated in April 2020.
The USS Decatur is the 23rd ship of the Arleigh Burke Class. Named for the early 19th Century Naval hero Stephen Decatur Jr, the ship was commissioned in August 1998. BAE Systems will perform much of the same upgrade work aboard the 505-ft-long Decatur as it will perform onboard the Stethem.
