BIW Lays Keel

On Tuesday, April 6, General Dynamics (GD) Bath Iron Works (BIW) celebrated the keel laying of the future USS Harvey C. Barnum, Jr. (DDG-124). The U.S. Navy named the ship in honor of Marine Corps Colonel Harvey C. Barnum, Jr., a Medal of Honor recipient who attended Tuesday’s ceremony. Colonel Barnum served in the Vietnam War and continued to serve his country afterward, eventually being named Acting Assistant Secretary of the Navy (Manpower and Reserve Affairs). The ship’s sponsor is Martha Hill, Colonel Barnum’s wife.

Colonel Barnum and Ms. Hill authenticated the keel by striking welding arcs onto a steel plate that will be incorporated into the ship. They were assisted by Marty Fish, a Specialist Welder and work leader with 34 years of experience at BIW, currently working on Main Machinery Room 1 of DDG-124. The laying of the keel and its authentication signifies the start of hull integration and the pre-cursor to final integration, launch and sea trials.

Ed Kenyon, Director of New Construction Programs for Bath Iron Works, hosted the ceremony and welcomed the audience, which included Acting Secretary of the Navy Thomas Harker, Maine Senators Susan Collins and Angus King, Representative Chellie Pingree, Navy personnel and BIW employees. «The keel-laying ceremony is an opportunity to re-affirm our commitment that a Bath-built ship is best built, at all stages of construction». Kenyon said. «We are proud to be building the Harvey C. Barnum, Jr. We will ensure that Colonel Barnum’s ship will be ready to serve our nation, nobly, as he did during his service in Vietnam and subsequent service to our nation».
