The Yamato-class battleships were designed and constructed by the Imperial Japanese Navy. 4 battleships of the class were planned but only 2, Yamato and Musashi, were completed. The third was converted to an aircraft carrier, and construction on the fourth ship was cancelled. Yamato-class was known for its 460mm guns, the biggest battleship guns in the world at the time.

Graf Zeppelin was an aircraft carrier built by the German Navy during WWII, and was the only aircraft carrier launched by Germany in history. Because the German Navy never had experience in building aircraft carriers, the construction plan did not proceed well and had many delays. It was completed many years after the launch.

USS Enterprise was the second of the Yorktown-class aircraft carriers. Her construction started in 1934. Enterprise was launched in 1936 and commissioned in 1938. She took part in a Fleet Problem exercise and was ordered to duty in the Pacific in 1940. She remained in the Pacific after the U.S. Navy’s restructure in 1941.

USS Archerfish was a Balao-class submarine. She was dispatched to provide lifeguard services for the B-29 pilots on their strikes against Tokyo on 9th November 1944. On 28th November, she achieved the first score by sinking the largest aircraft carrier at the time, Shinano. Archerfish received a Presidential Unit Citation after WWII for this.

HMS Prince of Wales was the second of the King George V-class battleship. She participated in the operation to intercept the German battleship Bismarck with the battle cruiser Hood. She also transported Churchill to Newfoundland to create the Atlantic Charter.

The Admiral Hipper-class heavy cruisers were built after Germany was permitted to reject the Treaty of Versailles legally. Germans believed cruisers should be used to operate against merchant shipping, and required the Admiral Hipper class to be large, able to travel long distance and with good firepower and defense. A total of 5 ships were built, but only 3 were completed.
