HMS Colossus (1882)
HMS Colossus was a Victorian battleship that marked an important stage in the Royal Navy’s transition from early ironclads to modern steel warships. Built at Portsmouth Dockyard, she was launched in 1882 and completed in 1886, following delays in the supply of her main guns. Her sister ship was HMS Edinburgh.
Designed under Nathaniel Barnaby, Colossus combined a steel hull, compound armour and steam propulsion. Her principal armament comprised four 12-inch breech-loading guns mounted in two turrets, supplemented by five 6-inch guns and smaller weapons. The turrets were positioned diagonally amidships, reflecting contemporary experiments with gun arrangements and firing arcs. Twin screws gave her a maximum speed of approximately 16.5 knots.
Colossus joined the Mediterranean Fleet in 1887 and remained there until 1893, supporting Britain’s naval presence in a strategically important region. She subsequently became the coastguard ship at Holyhead, while continuing to participate in fleet exercises during the 1890s.
Placed in reserve in 1901, she later served as a tender to the gunnery establishment HMS Excellent. She was sold for breaking up in 1908.
