Short answers, pulled from the story.
USS Yorktown (CV-5) was commissioned on the 30th of September 1937 at Naval Station Norfolk, Virginia, with Captain Ernest D. McWhorter in command. She was laid down on the 21st of May 1934 and launched on the 4th of April 1936, sponsored by Eleanor Roosevelt.
Yorktown's aircraft scored two bomb hits on the Japanese carrier Shōkaku on the 8th of May 1942, destroying Shōkaku's flight deck and triggering explosions in her gasoline storage tanks. Together with Lexington's planes, the strikes killed 108 Japanese sailors and wounded 40 more. Yorktown herself was hit by a single 250 kilogram bomb that killed or seriously wounded 66 of her crew.
After the Battle of the Coral Sea, Navy Yard inspectors estimated Yorktown needed at least two weeks of repairs. Workers at Pearl Harbor labored around the clock and made her seaworthy in 48 hours. One critical repair was skipped: her damaged superheater boilers were left untouched, limiting her top speed.
On the 4th of June 1942, dive-bombers from the Japanese carrier Hiryū hit Yorktown with three bombs, knocking out most of her boilers and stopping the ship. After her crew restarted the engines and she resumed 20 knots, a second strike from Hiryū landed two torpedo hits on her port side at 16:20, causing an uncontrollable list. The Japanese submarine I-168 fired a salvo of torpedoes on the 6th of June, striking Yorktown twice more and sinking the destroyer Hammann. Yorktown rolled upside-down and sank at 07:01 on the 7th of June 1942.
Oceanographer Dr. Robert Ballard, who had previously discovered the wrecks of the Titanic and the Bismarck, located the wreck of Yorktown on the 19th of May 1998. The ship was found three miles deep, sitting upright with much of her paint and equipment still visible after 56 years on the sea floor.
During a NOAA Ocean Exploration livestream on the 19th and the 20th of April 2025, a remotely operated vehicle explored the wreck and found a car suspected to be a 1941 Ford Super Deluxe Station Wagon, at least three SBD Dauntless dive-bombers, and intact murals on the ship's walls inside the hangar. The wreck lies within Papahānaumokuākea Marine National Monument.
