The U.S. aircraft carrier USS Harry S. Truman is undergoing Sea Trials following 10 months of deep maintenance and upgrades at the Norfolk Naval Shipyard.

The Navy said on Friday that CVN 75 departed the shipyard a day earlier than expected.

Work during the Planned Incremental Availability included upgrades to the ship's internal and external communication network, receiving and installing more than 3,000 Consolidated Afloat Networks and Enterprise Services assets and the Navy's next-generation tactical afloat network.

Sailors and contractors also teamed to repair nearly 4,500 reactor material items, which accounted for approximately 25 percent of the ship's overall work package.

Maintenance and refurbishments were made to shipboard systems. Among the projects were rehabilitation of the vessel's hangar bay and flight deck, the Navy said.

"This PIA was all about smart coordination between workforces and making sure we worked safely," Lt. Cmdr. Jeremiah Nelson, Truman's maintenance manager, said in a press release. "There was a ton of work to be done, but all hands did an excellent job of executing their mission. We had a lot of people on this project and they all helped to ensure this ship re-entered the fleet operating at its maximum potential."

The Truman will return to its home port at Naval Station Norfolk following the sea trials.

The carrier USS Dwight D. Eisenhower undergoes its PIA in August, the Navy said.
