HMS Neptune was an

hulk for the Naval Signal School, collided with HMS Hero
, and narrowly missed several other ships. She was scrapped in Germany in 1904.

Design and description

Right elevation and deck plan (with masts truncated) as depicted in Brassey's Naval Annual 1888

HMS Neptune was designed by

axial fire which was the original design's greatest virtue. The ship resembled, instead, an enlarged version of HMS Monarch.[1]

During the Russo-Turkish War of 1877–78 tensions dramatically escalated between Russia and Great Britain as the latter feared that the victorious Russian armies would occupy the Turkish capital of Constantinople, something that the British were not prepared to tolerate. They mobilized much of the Royal Navy in case war did break out and purchased a number of ironclads under construction, including Independencia, in 1878. The Brazilians sold the ship for £600,000, nearly twice as much as the £370,000 paid for Devastation a few years earlier. Another £89,172 was spent to bring her up to the standards of the Royal Navy.[2] In British service she was deemed "a white elephant, being a thoroughly bad ship in most respects—unlucky, full of inherent faults and small vices, and at times a danger to her own consorts".[1]

Neptune was 300 feet (91.4 m)

deep load.[3]

Neptune proved a poor

skylight over the wardroom, which as a result often flooded while the ship was at sea.[5]

Propulsion

Neptune had one 2-cylinder

boilers provided steam to the engine at a working pressure of 32 psi (221 kPa; 2 kgf/cm2). The engine had a total designed output of 8,000 indicated horsepower (6,000 kW), but produced a total of 8,832 ihp (6,586 kW) during sea trials in February 1878 which gave Neptune a maximum speed of 14.65 knots (27.13 km/h; 16.86 mph). The ship carried 670 long tons (680 t) of coal, enough to steam 1,480 nmi (2,740 km; 1,700 mi) at 10 knots (19 km/h; 12 mph) even though Sir George Tryon described her as "a weak ship in her engines and consuming a coal-mine daily".[6]

Neptune was barque-rigged, but her twin funnels were so close to the mainmast that the sails and rigging rapidly deteriorated in service. The mast was eventually stripped of sails and yards so that the ship only used the fore and mizzen masts; an unsightly combination described as "like a half-dressed harlot". During her 1886 refit the ship's masts and rigging were replaced by simple pole masts with fighting tops at the fore and mizzen positions only.[7]

Armament

The Brazilians had ordered four

torpedo tubes were mounted on the main deck, one on each side, for Whitehead torpedoes.[8]

The shell of the 16-

muzzle. The 14-calibre 9-inch gun weighed 12 long tons (12 t) and fired a 254-pound (115.2 kg) shell at a muzzle velocity of 1,420 ft/s (430 m/s). It was credited with the nominal ability to penetrate 11.3-inch (287 mm) armour.[9] The muzzle blast of the main guns was more than the deck immediately below the muzzles could stand and the full charge for the guns was reduced from 200 to 180 pounds (90.7 to 81.6 kg) of powder to minimize the damage.[8]

Armour

Neptune had a complete

armoured citadel 112 feet (34.1 m) long protected the bases of the gun turrets, the funnel uptakes and the ventilation shafts for the engines and boilers. The sides of the citadel were 10 inches thick and it was closed off by transverse bulkheads 8 inches (203 mm) thick. The chase guns at the bow were protected by a patch of 6-inch (152 mm) armour.[4]

The faces of the turrets were 13 inches (330 mm) thick while the sides were 11 inches (279 mm) thick. They were backed by 13–15 inches (330–381 mm) of

foremast. It could "be regarded as the first adequately installed conning position installed in a British" ironclad.[10]

Service

HMS Neptune was

launch her on 16 July 1874, but she stuck fast and did not budge. A second attempt was made on 30 July during which the ship got about one-third down the slipway and stuck, extensively damaging her bottom plating. She was finally launched on 10 September, after she had been lightened, and she was towed to Samuda Brothers for repairs and fitting out. The cost of the accident resulted in the bankruptcy of Dudgeons in 1875.[11]

Independencia ran her sea trials in December 1877.[12] On 22 December, she ran aground in the River Thames at Greenwich, Kent.[13] She was refloated on 25 December and towed in to Greenhithe, Kent.[14] Independencia was run into by the British steamship Firebrick at Greenhithe, Kent on 23 February 1878 and sustained slight damage.[15] She was purchased by the Royal Navy in March 1878 and renamed Neptune,[4] after the Roman god of the sea.[12] She was then taken to Portsmouth for alterations to her armament and other equipment that took until 3 September 1881 to complete.[4]

Neptune was

paid off into reserve in November 1893 in Portsmouth. In April 1902 she was transferred from Fleet reserve to Dockyard Reserve.[16] The ship was sold for £18,000 on 15 September 1903 for scrap.[5]

While under tow by the tug Rowland and another at her side out of Portsmouth on 23 October 1903, Neptune broke the cables connecting her to the tugs in a storm. With the winds and a strong flood tide pushing her, she was pushed back into the harbour and narrowly missed the training tender of the

orlop deck. Neptune then was pushed by the tides and winds toward HMS Hero and came to rest against the bow ram of Hero.[17] She was finally broken up in Lemwerder, Germany, in 1904.[5]
