English: Groton, Conn (Jun. 5, 2004) — Former First Lady Rosalynn Carter smashes a bottle of Champagne against the sail of the Seawolf-class nuclear attack submarine Jimmy Carter (SSN-23) during the ship’s christening ceremony. The new submarine honors the 39th president of the United States who is the only submarine-qualified man that went on to become the nation's chief executive. Differentiating the Jimmy Carter from all other undersea vessels is her Multi-Mission Platform (MMP), which includes a 100-foot hull extension that enhances payload capability, enabling it to accommodate advanced technology required to develop and test an entirely new generation of weapons, sensors and undersea vehicles. Jimmy Carter is the third and last of the Seawolf-class submarines.
