| | WARSHIP: BIG GUNS: BATTLSHIP BASICS |
 | | Gun turrets had first appeared in the mid-19th century, but, initially, their weight was too much for the ships that carried them. |
 | | Protection for gun turrets was key: Adopted from the French, the barbette, a fixed, armored shield, protected the platform on which the guns stood, and let guns fire out of the top. |
 | | The amount and placement of armor varied, but five locations were absolute musts: turrets, decks, barbettes, bulkhead (vertical parts of a ship's structure), belt (strip lining the bottom of the ship, partly under and partly over the waterline) and conning tower (command tower). |
