The US Navy’s first Arleigh Burke-class (DDG 51) Flight IIA restart destroyer, the USS John Finn (DDG 113), has successfully completed the initial builder's sea trials in the Gulf of Mexico.

Conducted by Huntington Ingalls Industries' (HII) Ingalls Shipbuilding in Pascagoula, Mississippi, US, the trials validated the operability of the ship’s main propulsion and other systems.

During the three-day trial, USS John Finn carried out a full power run and demonstrated its communication, damage control, and navigation systems, along with various hull, mechanical and electrical, and propulsion applications.

"Our test and trials, craftsmen and Supervisor of Shipbuilding team really managed this alpha trial well."

HII Ingalls operations vice-president George Jones said: “There is nothing like taking an Aegis destroyer to sea, and our test and trials, craftsmen and Supervisor of Shipbuilding team really managed this alpha trial well.

“We could really feel the quality of this ship while sailing through the Gulf. These ships are warfighters, and this extra set of trials will ensure the ship will get a lot of at-sea time in preparation for her delivery later this year.”

Christened after the navy’s first Medal of Honor recipient of World War II, USS John Finn can provide a range of capabilities suited for multi-threat air, surface and subsurface environments.

The 509ft-long vessel is equipped with an integrated air and missile defence radar to enhance its detection and reaction capabilities, while combating modern air warfare threats, as well as ballistic missile defence.

Powered by four gas turbine engines, the destroyer has a navigational draft of 31ft and can cruise at speeds in excess of 30k.

USS John Finn is soon scheduled to undergo a second round of sea trials before its third underway period with members of the US Navy's Board of Inspection and Survey.

The other future Arleigh Burke destroyers that are being built at HII are Ralph Johnson (DDG 114), Paul Ignatius (DDG 117), Delbert Black (DDG 119), and Frank E Petersen Jr (DDG 121).
