 breech loading guns, which had not proved satisfactory, to complement her 26 muzzle-loaders.

Edinburghs guns were carried in two turrets positioned near the centre of the ship, and the turrets were mounted en echelon. It was expected that, by mounting the turrets in this way, at least one gun from each turret could fire fore and aft along the keel line, and all four guns could fire on broadside bearings; it was intended that every part of the horizon could be covered by at least two guns. In practice it was found that firing too close to the keel line caused unacceptable blast damage to the superstructure, and cross-deck firing similarly caused damage to the deck.

Before Edinburgh the positioning of the conning tower in British ironclads had produced a variety of solutions; the difficulty was that the two important factors involved, maximum protection and maximum visibility, were essentially mutually incompatible. In this ship the conning tower was positioned forward of the foremast for good all-round vision; the chart-house was, however, placed on its roof, and the whole area surrounded by small guns, stanchions and other obstructions to the view; the problem was not solved until the political will to build larger ships in turn allowed more space for command facilities.

She was then briefly guardship at Hull, and was then guardship at Queensferry until 1897, when she went into reserve. In 1908 she was converted for use as a target ship, being fitted with fully backed and supported modern armour plates; the intention was to test and measure the effect on these plates of oblique impact by armour-piercing shells filled with lyddite, the most potent explosive of the period. As a result of these trials, which revealed major shortcomings in British high-explosive shells, the Controller, Jellicoe
