Following three bulkhead-rattling explosions off the coast of Florida, aircraft carrier USS Gerald R. Ford (CVN-78) and its crew began the ship’s last repair period before a long-delayed maiden deployment.

On Friday, the $13 billion carrier made the short trip across the James River to Huntington Ingalls Industries Newport News Shipbuilding for the six-month Planned Incremental Availability (PIA) following the explosive shock trials off the East Coast, the Navy announced on Saturday.

Ending in August, the carrier and crew endured three 40,000-pound blasts to test the Ford-class design as part of the full-ship shock trials.

In a roundtable with reporters in early August, Capt. Paul Lanzilotta, Ford’s commanding officer, said that from early assessments, the damage Ford suffered during shock tests would not add a significant amount of work to the maintenance period.

“Nothing that I’ve seen reported to me so far is in the category of so much more work that I expect it to add to the scope of the availability in terms of schedule,” he said.

The results from the thousands of sensors aboard Ford will be used to refine the design of the class moving forward.

Ahead of the shock trials, Ford completed 21 months of its post-delivery period after shipbuilder Newport News delivered the carrier to the Navy and the ship commissioned in 2017.

Part of the availability included testing and certifying the ship’s next-generation systems that were incorporated into the design—the electromagnetic launching system for the aircraft, the Advanced Arresting Gear, and the Dual Band air search radar.

As part of the maintenance, the yard and the Navy will complete the certification of the remaining four out of the 11 Advanced Weapons Elevators that have been a key new technology difference between the existing Nimitz-class carriers.

The deployment of Ford and its strike group will add carrier capacity to the strained East Coast force that has seen a string of double-pump deployments over the last several years.
