The ships were second-class battleships, lightly constructed, armed, and armoured by British standards; Swiftsure, in fact, suffered from structural weakness while in service and required hull strengthening, although Triumph did not have such problems.

, so they had to be longer and narrower for their displacement than ships built to British standards. They had a noticeably foreign appearance, with taller, narrower funnels than on other British battleships and a pair of heavy cranes amidships. Details in mast and anchor arrangements as well as the arrangement of magazines and shell-handling rooms also were different from British standards.

Armament

Neither ships' armament was of a standard Royal Navy type—they had all been specified to meet the requirements of the Chilean Navy.

 battleships—but that they could be useful against foreign cruisers, although the ships were not fast enough to catch cruisers.

They had a powerful secondary battery, being the only British battleships to mount 7.5 inch (190.5 mm) guns; these were of a different type than the 7.5 inch guns mounted on later British cruisers. The ships were armed with slightly different models, with Swiftsures guns made by her builders Armstrong designated Mark III, and Triumphs guns made by her builder Vickers designated Mark IV. Ten of the 7.5 inch guns were mounted in a central battery on the main deck, where they were criticized for taking up too much deck space; the other four were in casemates abreast the fore- and mainmasts on the upper deck.

The ships mounted tertiary armament, for defence against torpedo boats, of 3 inch guns firing 14-pound shells ("14-pounders"). This was in theory a heavier battery than the 12-pounders of most British battleships, although in practice the 14-pounders proved no more effective than the 12-pounders. These were the only such guns in the Royal Navy, and they were issued with the same 12.5-pound shell as its standard 3 inch gun, the QF 12 pounder 12 cwt

s ever built, with Triumph making nearly 20.17 knots (37.4 km/h) and Swiftsure achieving 20.87 knots (38.65 km/h)on trials, although these were short sprints under ideal conditions. Operationally they averaged a top speed of 19 knots (37.2 km/h), slightly faster than the battleships of the Duncan class, and this still was enough to qualify them as the fastest pre-deadnoughts.

The Swiftsures were the last British battleships to enter service with bow crests. They also were the last to enter service equipped with ventilation cowls.

Summary

Purchased solely to deny their acquisition by other navies, Swiftsure and Triumph met no outstanding Royal Navy requirement when purchased, did not match British standards in many ways, required the manufacturing of their own, special 10 inch (254 mm) ammunition, and were problematic for the British to employ, being too weakly armed and protected to face modern enemy battleships and too slow to catch enemy cruisers. Like all pre-dreadoughts, they were made obsolete by the completion of the revolutionary new battleship HMS Dreadnought
HMS Dreadnought (1906)
HMS Dreadnought was a battleship of the British Royal Navy that revolutionised naval power.
