USS Fitzgerald (DDG-62), an Arleigh Burke-class destroyer that was damaged last year during a collision that cost the lives of seven sailors, has arrived at Pascagoula, Mississippi, for repairs. The massive destroyer was transported from Yokosuka, Japan, onboard a heavy lift vessel called MV Transshelf. The vessel arrived in Pascagoula on Jan. 19.

“Fitzgerald is expected to spend several days in the Port of Pascagoula as the heavy lift ship will commence the reverse operation of unfastening, lowering and guiding the ship off the platform,” the Naval Sea Systems Command said in a statement. “The ship will then be taken to its designated pier space at Huntington Ingalls Industries shipyard.”

Because the ship will be in repair for a lengthy period, the Navy will also modernize the vessel while it is in drydock. “Due to the extent and complexity of the restoration, both repair and new construction procedures will be used to accomplish the restoration and modernization efforts. Various Hull Mechanical and Electrical (HM&E); Command, Control, Communications, Computers and Intelligence; and Combat System equipment, including the electronic warfare suite, radar, switchboard, gas turbine generator and air condition plant, require repair and/or replacement,” NAVSEA states.” Fitzgerald will also receive HM&E; Combat System; and Command, Control, Communications, Computers, Collaboration and Intelligence; upgrades that were originally planned for installation during a fiscal year 2019 availability.”

It will take roughly two year to repair and modernize Fitzgerald and her systems. “Work on the ship is expected to occur on a land level facility throughout 2018 and one to two quarters of 2019, followed by an extensive test and trials period to ensure all systems and spaces are restored to full functionality and operational capability,” NAVSEA said. “The entire restoration and modernization effort is expected to complete approximately 24-months post work commencement on the ship.”

It will take that long to repair the ship because of the extensive damage inflicted on the vessel during a June 17, 2017, collision with the Philippine-flagged ACX Crystal off the coast of Japan. Seven Navy sailors were killed and many others were injured during the accident, which caused extensive damage to Fitzgerald’s starboard side side above and below the waterline. The accident was traced back to an overworked and tired Navy crew and significant training issues onboard—and the vessel’s skipper is currently facing charges.

The Navy is making course corrections to improve training and to take some of the workload off its crews. However, this was a problem decades in the making and it will take a while to fix.
