SS Stephen Hopkins was a United States Merchant Marine Liberty ship that served in World War II. She was the only US merchant vessel to sink a German surface combatant during the war.
Steamship Stephen Hopkins was built at the Permanente Metals Corporation (Kaiser) shipyards in Richmond, California. Her namesake was Stephen Hopkins, a Founding Father and signer of the Declaration of Independence from Rhode Island. She was operated by Luckenbach Steamship Company under charter with the Maritime Commission and War Shipping Administration.
Action of 27 September 1942
She completed her first cargo run, but never made it home. On September 27, 1942, en route from Cape Town to Surinam, she encountered the heavily armed German commerce raider and her tender . Because of fog, the ships were only apart when they sighted each other. So was US Merchant Marine Academy cadet Edwin Joseph O'Hara, who single-handedly fired the last shots from the ship's 4-inch gun. Navy reservist Lt. (j.g.) Kenneth Martin Willett, commander of the Armed Guard detachment which manned the ship's 4-inch gun, was posthumously awarded the Navy Cross.
- Captain Paul Buck, master of SS Stephen Hopkins, was posthumously awarded the Merchant Marine Distinguished Service Medal by the President of the United States "for determination to fight his ship and his perseverance in engaging the enemy to the utmost until his ship was rendered helpless". The award was given by Admiral Emory S. Land.
- George S. Cronk, Second Engineer on the ship, sailed his lifeboat 2,200 miles for 31 days to save his shipmates. He was given the Merchant Marine Distinguished Service Medal by the President of the United States. The award was given by Admiral Emory S. Land.
- SS Stephen Hopkins was awarded the Gallant Ship Award for outstanding courage against overpowering odds by the U.S. Department of Transportation, Maritime Administration.
