PASCAGOULA -- First lady Michelle Obama will sponsor the Coast Guard's third Legend-class national security cutter, which is about 25 percent complete at Northrop Grumman Shipbuilding's Pascagoula yard, officials said Monday. In August 2007, the Coast Guard awarded Northrop Grumman a $285.5 million contract to construct the Stratton. The 418-foot cutter, WMSL 752, is named in honor of Dorothy C. Stratton, the first female commissioned officer in the Coast Guard. Stratton served as director of the SPARS, the Guard's women's reserve, during World War II.
