Deck gun
- "Deck gun" can also mean a type of big water nozzle used for firefighting.
A deck gun is a type of artillery cannon mounted on the deck of a ship or submarine.
The deck gun was used as a defensive weapon against smaller boats or ships and in certain cases where torpedo use was limited. Typically a crew of three; gunner, loader and layer (pointer, trainer, and loader in the US), operated the gun, while others were tasked with supplying ammunition. A small locker box held a few 'ready-use' rounds. With a well-drilled, experienced crew, the rate of fire of a deck gun could be 15 to 18 aimed shots per minute.
