Design and description
The Hector-class ironclads,Ironclad is the all-encompassing term for armored warships of this period. Armoured frigates were basically designed for the same role as traditional wooden frigates, but this later changed as the size and expense of these ships forced them to be used in the line of battle. like their immediate predecessors, the , were designed as smaller and cheaper versions of the armoured frigates. They were modified versions of the Defence-class ships with additional armour and more powerful engines.HMS Hector was 280 in 2 in (85.39 m) long between perpendiculars. She had a beam
Beam (nautical)

s on 23 February 1864 Hector had a maximum speed of 12.36 knots (6.7 m/s). The ship carried 450 long tons (457.2 t) of coal, enough to steam 800 nautical miles (1,481.6 km) at full speed. Hector was the first British ironclad to have her machinery made by her builders.

and much was hoped for them. To partially alleviate their overweight condition the ships were not fully armed and only received four 110-pounders on the upper deck and twenty 68-pounders on the main deck behind armour. Firing tests carried out in September 1861 against an armoured target, however, proved that the 110-pounder was inferior to the 68-pounder smoothbore gun in armour penetration and repeated incidents of breech explosions during the Battles for Shimonoseki and the Bombardment of Kagoshima

Hector was rearmed during her 1867–68 refit with sixteen 7-inch and two 8 inches (20 cm) rifled muzzle-loading guns. The two 8-inch guns were mounted on the quarterdeck where they could be fought in all weathers and four 7-inch guns were also fitted on the upper deck.

She cost £294,000Adjusted for inflation, the ship cost in current pounds. to build, including a payment of £35,000 to her builders who had underestimated their costs. She served with the Channel Fleet until 1867, when she paid off to be re-armed and to refit. She formed part of the Southern Reserve Fleet between 1868 until 1886; during this time her only military activity occurred when she was detailed to service in the Particular Service Squadron under the command of Admiral Hornsby during the Russian war scare of June to August, 1878.
