Yorktown

USS Yorktown (CV-5) was an aircraft carrier commissioned in the United States Navy from 1937 until she was sunk at the Battle of Midway in June 1942. Yorktown played an important part in the battle, assisting in the destruction of multiple enemy aircraft carriers, and absorbing the majority of enemy counter attacks. She was named after the Battle of Yorktown in 1781 and the lead ship of the Yorktown class which was designed after lessons learned from operations with the large converted battlecruiser Lexington class and the smaller purpose-built USS Ranger. She was sunk by Japanese submarine I-168 on 6 June 1942 during the Battle of Midway.

Design

 * A Bald Eagle can be seen landing on Yorktown, a reference to both the ship's adopted insignia, and as a symbol of American ideals. This eagle would later end up in Enterprise's hands, after the sinking of Yorktown.
 * "YKTN" can be seen draped across the deck of the carrier, and is quite obviously short for Yorktown.
 * AGrumman F4F Wildcat fighter and a Douglas SBD Dauntless dive bomber can be seen flying around Yorktown.

Lines

 * Self-introduction - Yorktown, after receiving several bomb and torpedo hits, was deemed unfit to be saved, as the flooding was uncontrollable. She would not actually sink until the next morning, remaining stubbornly afloat for several hours after being torpedoed again by I-168.
 * Acquisition - She refers to American neutrality as "pre-war etiquette," owing to the fact that even though America maintained a neutral position in both World Wars, she was still brought into both of them.
 * Secretary line 1 (idle) - "This one" refers to her eagle, and she foreshadows her own demise by questioning whether she should be the one to keep her.
 * Pledge - she refers to her sinking into the abyss 3 miles under.

Skills

 * Her skills "Vengeful Strike" refers to the dive bombers that attacked 3 of the 4 carriers at the Battle of Midway practically unopposed, and her dive bombers specifically doomed the Souryuu.
