Huntington Ingalls Wins $604.3M Contract to Build US Navy’s DDG 121

In March of 2015, the Navy awarded a USD$604.3 million contract to Huntington Ingalls Industries for construction of the Arleigh Burke-class guided missile destroyer DDG 121. This deal is in addition to a previously awarded contract to build the Arleigh Burke-class DDG 51. Manager of this project George Nungesser stated, “The DDG 51 program has been the backbone of Ingalls Shipbuilding for the past three decades.” In order to reduce costs and increase efficiency, Huntington Ingalls has decided to keep the production line in the shipyard where the shipbuilding crew can work in the same area. Furthermore, because five ships will be built in the span of a year, the company can purchase and produce in bulk, further reducing costs and conserving resources. Huntington Ingalls has embarked on a continuing business venture with the Navy, including the procurement of twenty-eight previous destroyers and four currently under construction, including John Finn (DDG 113), Ralph Johnson (DDG 114), Paul Ignatius (DDG 117) and Delbert D. Black (DDG 119). These destroyers have earned the reputation of being highly dynamic and capable defense tools.

The latest upgrade includes a new radar, AN/SPY-1D(V), which allows for more clarity and precision. Furthermore, they are equipped with four GE LM 2500 gas turbines. The SWG-1A serves as a weapon control system for Harpoon anti-ship missiles, the SWG-3 for Tomahawk cruise missiles, and 2 missile fire control systems. More specifically, the ships are equipped with the 56 Raytheon Tomahawk cruise missiles, guided by a TERCOM-aided navigation system and fired by two Lockheed Martin Mk41 vertical launchers.

Huntington Ingalls Industries, founded on March 31, 2011, was formerly part of Northrop Grumman Shipbuilding.
