HMS Temeraire was an ironclad battleship of the Victorian Royal Navy which was unique in that she carried her main armament partly in the traditional broadside battery, and partly in barbettes on the upper deck.
Propulsion

Temeraire was equipped with two Humphrys & Tennant 2-cyl. steam engines, each driving one shaft and developing a total of 7,697 hp (5,661 kW), with which she reached a top speed of 14.65 knots (16.86 mph). Steam was supplied by twelve boilers. The ship could carry a maximum of 629 t. coal. Temeraire was rigged as a two-masted barque and had a sail area of 25,000 sq ft. The ship's crew consisted of 580 officers and ratings.[1]

Armament
Her armament was partly conventional, being deployed on the broadside, and partly experimental. She was the first British ship to use barbettes of any kind, with the barbettes located on the midline on the upper deck. The armament consisted of four 11-inch muzzle-loading guns, one each on the forecastle and stern, and one each at the forward corners of the central battery to port and starboard. The 11-inch guns were installed on a Moncrieff mount, which had a mechanism for raising and lowering the gun. The mount was on a massive turntable that provided enough space for the hydraulic ramrod. The loading and lifting process, as well as the rotation of the mount, were operated by a disguised stand with four control levers. When the gun was extended and aimed at the target, it was adjusted to elevation graduated in degrees by a rod linkage on each side of the breech. A full gun crew consisted of six men, but the guns could be operated by three in an emergency. In addition, four 10in muzzle-loading guns were located in the rear of the central battery, two on each broadside. To protect against attack by boats armed with torpedoes, the ship received four 20-pounder breech-loading guns. Temeraire was also fitted with two launchers for spar torpedoes. In 1884, the 20-pounders were replaced by four 25-pounder breech-loading guns, and four 3-pounder Hotchkiss and ten 3-pounder Nordenfelt QF guns were also added to the ship.[2][1]
Armour
The armoured belt extended along the entire length of the ship. It was 11in thick amidships and had a total height of 18.8 ft, of which 10 ft was above and 8.9 ft below the waterline. Towards the bow and stern it tapered to 5in and 5.5in respectively. The central battery was protected by 8in sides and 5in transverse bulkheads. The oval barbettes were protected by 10in forward and 8in aft. This shape was necessary to make room not only for the guns to be lowered, but also for a hydraulic ramrod, which was opposite the gun muzzle and almost as long as the barrel itself. The wider end was open at the top to allow the gun to rise and fire, and the narrower end with the ramrod was covered with iron plates. Its distinctive feature was a complete and continuous armour by a parapet that rose 36in above the deck surrounding it, protecting the gun crew and the gun itself when loaded or not in use.[2][1]
