Found this on facebook and copied it down, thought it was cool.
Did you know? One turret from the Japanese battleship Yamato, weighs more than an entire Fletcher-class destroyer.
The Yamato’s main armament consisted of nine 46 cm (18.1 inch) Type 94 main guns, which were the largest caliber guns ever mounted on a warship. The guns were arranged in three gun turrets, each gun weighed 147.3 tonnes and were 21.13 metres (69.3 ft) long.
