Mormacsky-class roll-on roll-off ship

The Mormacsky class is a group of four roll-on/roll-off container ships that Ingalls Shipbuilding built at Pascagoula, Mississippi, to the Maritime Administration design C5-S-78a for the Moore-McCormack Lines. The ships were the Mormacsky, the Mormacstar, the Mormacsea and the Mormacsun, delivered between 1969 and 1970, each about 601.5 feet long with a beam of 90 feet and a deadweight of about 16,000 tons. They had varied later careers under other owners and names. The Mormacsky was laid down on 1 April 1968 and became the Navy auxiliary SS Curtiss, the Mormacsun became the Young America and then the SS Wright in 1986, and the Mormacstar was renamed several times and ended as the Cape Nome in the National Defense Reserve Fleet. The Mormacsea became the Defiance, the American Rover and the Rover, and was scrapped in 1993 at Alang, India.
