Huntington Ingalls Industries’ (HII) Ingalls Shipbuilding division has announced the successful conclusion of builder’s trials for the future USS Jack H. Lucas (DDG 125).

Jack H. Lucas is the US Navy’s first Flight III Arleigh Burke-class guided missile destroyer.

Conducted in the Gulf of Mexico, the trials saw the vessels being put through an extensive list of events, such as hull, mechanical, and electrical tests.

It provided Ingalls’ test and trials team to evaluate the destroyer’s SPY-6 arrays, the machinery control system and the new electric plant’s remote operability.

Ingalls Shipbuilding president Kari Wilkinson said: “Getting DDG 125 underway is a significant milestone in keeping this first Flight III ship on schedule and reflects the hard work and dedication of our combined Ingalls and Navy team to ensure a successful sea trial.

“We are all very happy with how DDG 125 performed, and we look forward to delivering this highly advanced ship to the Navy.”

As the fourth Flight upgrade, the Flight III vessels feature the AN/SPY-6(V)1 Air and Missile Defense Radar (AMDR) and several design modifications to the electrical power and cooling capacity.

Jack H. Lucas will be the 75th Arleigh Burke (DDG 51) class destroyer of the US Navy.

Program Executive Office (PEO) Ships DDG 51 class programme manager captain Seth Miller said: “Embarking on Builder’s Sea Trials is a significant accomplishment for the DDG 51 programme.

“As the first Flight III ship, DDG 125 is the culmination of years of dedication and perseverance to design, build, and integrate the Flight III capability of BL 10, AMDR and the supporting systems such as the new electric plant and associated upgrade to the machinery control system.”

Ingalls is also building the future Ted Stevens (DDG 128), Jeremiah Denton (DDG 129), George M. Neal (DDG 131) and Sam Nunn (DDG 133) for the Navy.
