HMS Collingwood (1882)

HMS ''Collingwood'' was the lead ship of her class of ironclad battleships built for the Royal Navy during the 1880s. The ship's essential design became the standard for most of the following British battleships. Completed in 1887, she spent the next two years in reserve before she was assigned to the Mediterranean Fleet for the next eight years. After returning home in 1897, the ship spent the next six years as a guardship in Ireland. ''Collingwood'' was not significantly damaged during an accidental collision in 1899 and was paid off four years later. The ship was sold for scrap in 1909 and subsequently broken up.

Background and design

At the time of her design, she was not considered as being the forerunner of any class; she was designed by the Director of Naval Construction, Sir Nathaniel Barnaby, as a one-off as an answer to the French s, which carried three heavy guns on the centreline and a number of smaller pieces on the broadside. He made several proposals to the Board of Admiralty, but they were all rejected. Barnaby's final submission was inspired by the four French s laid down in 1877–1878 and was a return to the configuration of with the primary armament positioned fore and aft of the central superstructure, but with the breech-loading main armament mounted in barbettes, as per the French ships,Chesneau & Kolesnik, p. 29 which allowed them to be sited further above the waterline than ''Devastation''s guns.Parkes, p. 302 The Board modified Barnaby's design by adding of length and to guarantee a speed of at deep load. It also substituted four smaller guns for Barnaby's two guns. The additional length and the Board's acceptance of the hull lines from increased the size of the ship by .

Barnaby was severely criticised, particularly by Sir Edward Reed, himself a former Chief Constructor of the Royal Navy, because ''Collingwood''s waterline armour belt was concentrated amidships and did not extend to the ends of the ship. Reed believed that this weakness meant that the ship could be sunk from the consequent uninhibited flooding if her unarmoured ends were riddled by shellfire and open to the sea. Barnaby deliberately selected a hull shape with narrow, fine ends to limit the volume of the hull that could be flooded and situated the armoured deck below the waterline to prevent it from being pierced by enemy shells and flooding the lower part of the ironclad. Furthermore, he heavily subdivided the hull to limit the amount of water that could enter through any one hit and placed coal bunkers above the armoured deck to absorb the fragments from exploding shells. Unbeknownst to his critics, ''Collingwood'' was tested in 1884 with her ends and the large spaces in her hold ballasted with water and her draught only increased by and she lost a minor amount of speed. The price was that the ship lacked buoyancy at her ends and tended to bury her bow in oncoming waves rather than be lifted over them. Her speed was greatly reduced in a head sea and the resulting spray made working the guns very difficult. ''Collingwood'' tended to roll heavily and was not regarded as a good seaboat. Despite these issues, her basic configuration was followed by most subsequent British ironclads and predreadnought battleships until the revolutionary of 1905.

The ship had a length between perpendiculars of , a beam of , and a draught of at deep load. She displaced at normal load and had a complement of 498 officers and ratings.Parkes, p. 301

The ship was powered by a pair of 2-cylinder inverted compound-expansion steam engines, each driving one propeller. The Humphreys engines produced a total of at normal draught and with forced draught, using steam provided by a dozen cylindrical boilers with a working pressure of . She was designed to reach a speed of at normal draught and ''Collingwood'' reached from on her sea trials, using natural draught. She was the first British ironclad to be equipped with forced draught and the ship only reached a speed of from while using it during her sea trials because her engines were incapable of handling the additional steam. ''Collingwood'' carried a maximum of of coal that gave her a range of at a speed of .Winfield & Lyon, p. 258

Armament and armour

The ship had a main armament of 25-calibre rifled breech-loading (BL) Mk II guns. The four guns were mounted in two twin-gun barbettes, one forward and one aft of the superstructure. The barbettes were open, without hoods or gun shields, and the guns, mounted on a turntable, were fully exposed. They could only be loaded when pointed fore and aft with an elevation of 13°. The shells fired by these guns were credited with the ability to penetrate of wrought iron at ,Parkes, p. 316 using a charge of of prismatic brown powder. At maximum elevation, the guns had a range of around .Campbell 1981, p. 202

The secondary armament of ''Collingwood'' consisted of six 26-calibre BL Mk IV guns on single mounts positioned on the upper deck amidships, three on each broadside. They fired shells that were credited with the ability to penetrate of wrought iron at 1000 yards. They had a range of at an elevation of +15° using prismatic black powder. Beginning around 1895 all of these guns were converted into quick-firing guns (QF) with a much faster rate of fire. Using cordite extended their range to . For defence against torpedo boats the ships carried a dozen QF 6-pounder Hotchkiss guns and eight QF 3-pdr Hotchkiss guns. They also mounted four above-water torpedo tubes, one pair on each broadside.

''Collingwood''s waterline belt of compound armour extended across the middle of the ship between the rear of each barbette for . It had a total height of deep of which was below water and above at normal load; at deep load, the ship's draught increased by another 6 inches. The upper of the belt armour was thick and the plates tapered to at the bottom edge. Lateral bulkheads at the ends of the belt connected it to the barbettes; they were thick at main deck level and below.Parkes, p. 303

Each barbette was a roughly pear-shaped, 11-sided polygon, in size with sloping walls thick and a rear. The main ammunition hoists were protected by armoured tubes with walls 10–12 inches thick. The conning tower also had 12-inch thick walls as well as roofs thick. The deck of the central armoured citadel had a thickness of and the lower deck was thick from the ends of the belt to the bow and stern.

Construction and career

''Collingwood'', named after Admiral Cuthbert Collingwood, Horatio Nelson's second-in-command in the British victory at the Battle of Trafalgar,Silverstone, p. 223 was the second ship of her name to serve in the Royal Navy. The ship was laid down at Pembroke Dockyard on 12 July 1880 and launched by Mrs. Louise Chatfield, wife of the dockyard's Captain-Superintendent, Captain Alfred Chatfield, on 22 November 1882. While conducting gunnery trials on 4 May 1886, ''Collingwood''s rear left gun partially shattered and all of the Mk II guns were withdrawn from service. They were replaced by heavier Mk Vw models with approximately the same performance. Excluding her armament, she cost £636,996. The ship was commissioned at Portsmouth on 1 July 1887 for Queen Victoria's Golden Jubilee Fleet review and was paid off into reserve in August.Parkes, p. 304

''Collingwood'' was recommissioned for the annual summer manoeuvres for the next two years, before she was assigned to the Mediterranean Fleet, where she served from November 1889 until March 1897, with a refit in Malta in 1896. Captain Charles Penrose-Fitzgerald commanded the ironclad when she joined the Mediterranean Fleet in 1889. The ship became the coastguard ship at Bantry, Ireland, upon her return. ''Collingwood'' accidentally collided with the cruiser in Plymouth harbour on 23 January 1899, badly damaging the latter ship, but was not significantly damaged herself. She took part in the fleet review held at Spithead on 16 August 1902 for the coronation of King Edward VII, and was back in Ireland later that month when she received the Japanese cruisers and to Cork. The ship was paid off into the reserve in June 1903 and was transferred to East Kyle in January 1905. ''Collingwood'' remained there until she was sold for scrap to Hughes Bolckow at Dunston, Tyne and Wear for £19,000 on 11 May 1909.
