Ise is the boss from mission 7 in 1943: The Battle of Midway. It is a hybrid battleship-carrier vessel. It was named Choko in the NES and the PC version.
Real World Information[]
Ise (伊勢(戦艦) Ise (senkan)), was the lead ship of the two-vessel Ise-class battleship of the Imperial Japanese Navy, which saw combat service during the Pacific War. Ise was named after Ise Province, one of the traditional provinces of Japan, now part of Mie Prefecture.
To partially compensate for the loss of carrier strength at the Battle of Midway, Navy Aircraft Department began plans to convert the Ise-class battleships to full-sized aircraft carriers each carrying 54 planes. This concept was abandoned due to lack of time and resources and a hybrid battleship/carrier concept was adopted. Ise was dry-docked, and her aft No. 5 and No. 6 main turrets were removed and replaced by a hangar surmounted by a 70 m (230 ft) long flight deck and a "T"-shaped aircraft elevator.

In the Game[]
Ise is the third battleship fought in the game, and is unique in that the frontal part of it's hull is similar to the aircraft carriers, with a aircraft elevator allowing it to launch enemy fighters at the player all while constantly shooting. It is the only boss in the game with a hybrid design.
