Builder’s Trials consist of a series of in-port and at-sea demonstrations that allow the shipbuilder, Bath Iron Works (BIW), and the U.S. Navy to assess the ship’s systems and its readiness for delivery.

«With the successful completion of these trials, we move closer to adding DDG-116 and her exceptional capabilities to the Fleet», said Captain Casey Moton, DDG-51 class program manager, Program Executive Office (PEO) Ships. «The Navy and Industry team worked diligently to ensure the ship operates at peak performance».

The DDG-51 class ships currently being constructed are Aegis Baseline 9 Integrated Air and Missile Defense destroyers with increased computing power and radar upgrades that improve detection and reaction capabilities against modern air warfare and Ballistic Missile Defense threats. The Aegis Combat System will enable USS Thomas Hudner (DDG-116) to link radars with other ships and aircraft to provide a composite picture of the battle space. When operational, USS Thomas Hudner (DDG-116) and her sister ships will serve as integral players in global maritime security.

The future USS Thomas Hudner (DDG-116) will return to sea to conduct Acceptance Trials with the U.S. Navy’s Board of Inspection and Survey later this spring. During Acceptance Trials, all systems and gears will be inspected and evaluated to ensure quality and operational readiness prior to the U.S. Navy accepting delivery.

BIW is currently in production on the future Arleigh Burke class destroyers USS Daniel Inouye (DDG-118), USS Carl M. Levin (DDG-120) and USS John Basilone (DDG-122), as well as future Zumwalt class destroyers USS Michael Monsoor (DDG-1001) and USS Lyndon B. Johnson (DDG-1002).

As one of the Defense Department’s largest acquisition organizations, PEO Ships is responsible for executing the development and procurement of all destroyers, amphibious ships, special mission and support ships, and boats and craft.
