On Saturday July 15, Gen. Robert Magnus, assistant commandant of the U.S. Marine Corps, will give the principal address at the christening of Green Bay (LPD 20), an amphibious transport dock ship being built by Northrop Grumman Corporation. The ceremony will be held at the company's New Orleans Operations beginning at 10 a.m. The name Green Bay honors the city of Green Bay, Wis. One of the oldest settlements in the country, Green Bay has been a home to the record-making football team, the Green Bay Packers, since 1919. Green Bay (LPD 20) is the fourth ship in the San Antonio (LPD 17)-class of amphibious transport dock ships being built for the U.S. Navy/U.S. Marine Corps by Northrop Grumman.
