Input: Question: When were the ships that the Victory ships were designed to replace first built? Passage:Named after Whittier College in Whittier, California, the ship was built at the California Shipbuilding Yard (Calship) in Los Angeles, California in just 82 days and was delivered on 18 July 1945. The Whittier City and Whittier College was named for author John Greenleaf Whittier. SS Whittier Victory was the 798 of the 10,500-ton class known as Victory ships, built under the Emergency Shipbuilding program. Victory ships were designed to replace the earlier Liberty ships. Liberty ships were designed to be used solely for World War II. Victory ships were designed to last longer and serve the US Navy after the war. The Victory ship differed from a Liberty ship in that it was faster, longer, wider, taller, and had a thinner stack set farther toward the superstructure and a long raised forecastle. She was a United States Merchant Marine ship operated by the Moore-McCormack Lines for World war 2. She loaded up cargo at a few west coast ports and streamed to support the Pacific War. SS Whittier Victory delivered supplies in the island-hopping campaigns towards the Empire of Japan. As a Merchant Marine ship, she had a civilian crew to man the ship and US Navy Armed Guards to man the deck guns.
