DDG-121 Start Fab

Huntington Ingalls Industries’ (HII) Ingalls Shipbuilding division on April 27 marked the start of fabrication for the Arleigh Burke-class (DDG-51) destroyer USS Frank E. Petersen Jr. (DDG-121) for the U.S. Navy. The start of fabrication signifies that 100 tons of steel have been cut.

«This is a significant day for our shipbuilders and for the U.S. Navy as Ingalls once again begins fabrication of another destroyer», said George Nungesser, Ingalls’ DDG-51 program manager. «We have delivered 28 of these ships to the U.S. Navy, and our experienced and talented shipbuilders are more than ready to produce another high-quality destroyer. This is our fourth destroyer started in three years, and we are seeing the efficiencies that come from building these ships back-to-back».

DDG-121 is the third of five DDG-51 destroyers the company was awarded in June 2013. The five-ship contract, part of a multi-year procurement in the DDG-51 program, allows Ingalls to build ships more efficiently by buying bulk material and moving the skilled workforce from ship to ship.

The guided missile destroyer honors Frank Emmanuel Petersen Jr., who was the first African-American aviator and general officer in the United States Marine Corps. After entering the Naval Aviation Cadet Program in 1950, Petersen would go on to fly more than 350 combat missions throughout the Korean and Vietnam wars.

The highly capable, multi-mission ship can conduct a variety of operations, from peacetime presence and crisis management to sea control and power projection, all in support of the United States’ military strategy. Arleigh Burke-class destroyers are capable of simultaneously fighting air, surface and subsurface battles. The ship contains myriad offensive and defensive weapons designed to support maritime defense needs well into the 21st century.
