The US Navy’s Arleigh Burke-class Flight IIA guided missile destroyer, the future USS Frank E Petersen Jr (DDG 121), has successfully completed acceptance trials.

The vessel spent two days at sea for the final round of trials completed by Huntington Ingalls Industries ’ (HII) Ingalls Shipbuilding division.

Last month, the ship successfully completed builder’s trials.

Ingalls Shipbuilding president Kari Wilkinson said: “The successful completion of acceptance trials is an extremely rewarding accomplishment for Ingalls and for our partners who work closely with us to ensure we achieve this milestone together.

“We are proud of our shipbuilders for working as a team to move the DDG 121 one step closer to delivery.”

The US Navy’s Inspection and Survey board inspected the ship’s performance during a set of demonstrations while at pier side and underway.

The vessel’s onboard systems such as navigation, damage control, mechanical and electrical systems, propulsion applications, combat systems and communications were tested.

US Navy Program Executive Office (PEO) Ships DDG 51 programme manager captain Seth Miller said: “Following an impressive performance during builder’s trials in August, the ship continued to demonstrate her readiness to join the fleet through successful completion of acceptance trials.

“The [US] Navy and our industry team are looking forward to delivering another advanced multi-mission warship to the fleet.”

The DDG 121 has been named after US Marine Corps’ (USMC) first African-American aviator and officer, lieutenant general Frank E Petersen Jr.

It is the 71st Arleigh Burke-class destroyer and the fifth in a fleet of 21 DDG-51 vessels currently under contract for the US Navy.

The 509.5ft-long destroyer was christened in October 2018 and will feature the Aegis Baseline 9C2 combat system.

The Flight IIA DDG-51s incorporate some design changes, including the addition of a helicopter hangar.

The US Navy is expected to receive the ship later this year from the Ingalls Shipbuilding division in Pascagoula, Mississippi.

The division is also working on the Lenah Sutcliffe Higbee (DDG 123), Ted Stevens (DDG 128), Jeremiah Denton (DDG 129) and Jack H Lucas (DDG 125) destroyers.
