Submarine[a] is an electro-mechanical arcade game that was released by Namco in 1978, and was licensed to Midway for US manufacturing and distribution in September 1979.

Pressing the button on the right handle will fire a torpedo, and the goal is to shoot down all of the submarines in the fastest amount of time.

The November 11, 1978 issue of Cashbox called it ""one of the most realistic" games of its kind "ever put into a cabinet".

[6] Submarines was designed to take full advantage of Namco's engineering technology, and was well-received by the press.
