HMVS Cerberus (Her Majesty's Victorian Ship) is a breastwork monitor that served in the Victoria Naval Forces, the Commonwealth Naval Forces (CNF), and the Royal Australian Navy (RAN).

Built for the colony of Victoria, Cerberus was completed in 1870, and arrived in Port Phillip Bay in 1871, where she spent the rest of her career. The monitor was absorbed into the CNF following Federation in 1901, and was renamed HMAS Cerberus when the navy became the RAN in 1911. By World War I, Cerberus' weapons and boilers were inoperable; the ship was retasked as a guardship and munitions store, while carrying the personnel of the fledgling Royal Australian Naval College on her paybooks. In 1921, the ship was renamed HMAS Platypus II, and tasked as a submarine tender for the RAN's six J class submarines.

In 1924, the monitor was sold for scrap, and was sunk as a breakwater off Half Moon Bay. The wreck became a popular site for scuba diving and picnics over the years, but there was a structual collapse in 1993. There have been several campaigns to preserve the ship (one of which is ongoing as of 2010), as she is one of the last monitors, the only surviving ship of the Australian colonial navies, and the only surviving ship in the world with Coles turrets.[1][2]

Design

Named for Cerberus, the three-headed guard dog of Hades from Greek mythology, Cerberus was the first of the 'breastwork monitors', which differed from previous ironclad warships by the fitting of a central superstructure containing rotating turrets.[3][4] The ship was designed by Edward James Reed, Chief Constructor to the Royal Navy.[5] Cerberus had one sister ship, HMS Magdala, and an additional five ships of similar design were constructed for coastal defence around the British Empire.[6][4] These vessels were unofficially referred to as the 'Monster class'.[7]

The monitor was 225 feet (68.6 m) long, 45 feet 1 inch (13.7 m) wide, and with a draught of 15 feet 6 inches (4.7 m).[5] She had a standard ship's company of 12 officers and 84 sailors, with an additional 40 to man the ship in wartime.[8] Cerberus had a maximum speed of 9.75 knots (18.06 km/h; 11.22 mph), with an economical speed of 6 knots (11 km/h; 6.9 mph).[5]

Her twin screws were driven by two horizontal twin-cylinder, double-acting, simple steam engines[9] made by Maudslay Son & Field.[5] They had 43-inch (110 cm) bore, 27-inch (69 cm) stroke, and were provided with 30 psi (210 kPa)[10] steam produced by five coal-fired boilers with 13 furnaces.[citation needed] The steam engines generated 1,369 indicated horsepower (1,021 kW) on trials and drove two propellers with a diameter of 12 feet (3.7 m)[11] Cerberus was the first British warship to be solely steam-powered.[4] The monitor had a bunkerage of 240 tons of coal; this would last just under five days at maxumum speed (50 tons consumed per day), and ten days at economical speed (24 tons per day).[5] The monitor was not suited to ocean travel.[12]

The main armament was four 10-inch guns, fitted to two turrets.[4] The four guns weighed 18 long tons (18 t) each, were muzzle-loaded, had to be withdrawn completely inside the turret to be reloaded, and could fire a 400-pound (180 kg) shell up to 4,000 yards (3,700 m) once every three minutes.[8] The turrets were mounted fore and aft; each had a crew of 33, had a 270° field of fire, and had to be hand-cranked into position.[4] The turrets were of a design created by Cowper Phipps Coles.[13]

The ship had armour plating ranging from 6 to 8 inches (150 to 200 mm) in thickness for the waterline armoured belt on her hull, which was backed by 9 to 11 inches (230 to 280 mm) of teak.[14] The citadel armour protecting the breastwork ranged in thickness from 8 to 9 inches (200 to 230 mm), and gun turrets had 10-inch (250 mm) faces and 9-inch sides.[14] Cerberus was protected by an armored deck that was 1 to 1.25 inches (25 to 32 mm) thick.[14][15] For added protection, Cerberus could take water into ballast tanks, decreasing her already low freeboard until only the turrets and breastwork were visible.[8][16]

Cerberus and ships of her type were described by Admiral George Alexander Ballard as being like "full-armoured knights riding on donkeys, easy to avoid but bad to close with."[17] Robert Gardiner, Roger Chesneau, and Eugene M Kolesnik, the editors of Conway's All the World's Fighting Ships: 1860–1905, pointed out that "[Cerberus] [represents] the beginnings of practical turret ship design in Britain, having no sail power and being fitted with fore and aft turrets with almost uninterrupted arcs of fire."[14] When she entered service, the monitor was considered superior to any other warship operating in the Australiasian region.[8] The design of Cerberus was a major influence on battleship design until the early 1900s, when HMS Dreadnought made all pre-dreadnought battleship designs obsolete.[8]

Construction

In 1866, the Victorian government ordered a ship to supplement the shore-based fortifications of Port Philip Bay, and to defend the colony in the event of a Russian attack.[8][12] Cerberus was ordered on the understanding that if she operated in any role other than the defence of Victoria, she would revert to Admiralty control.[7]

The monitor was constructed by Palmers Shipbuilding at their Jarrow-on-Tyne shipyard.[8] She was laid down on 1 August 1867, launched on 2 December 1868, and completed in August 1870.[5] Cerberus cost £117,556 to build, with the British Admiralty meeting 80% of the cost.[8]

Operational history

On completion, Cerberus was registered as a merchant vessel for the voyage to Australia.[18] She first attempted to sail from Chatham for Melbourne on 29 October 1870, but returned within days because of gale conditions, which made the ship uncontrollable.[18] After being fitted with three temporary masts and sails, Cerberus departed for a second time on 7 November, and despite similar conditions, was able to persevere.[18] The ship travelled via the Suez Canal, with frequent stops to refuel wherever possible because of her ten-day bunker capacity.[citation needed] Her flat bottom and shallow draught meant that the monitor could roll up to 40° from the centreline in bad weather.[18] Her ship's company nearly mutinied on several occasions.[18]

The monitor reached Melbourne on the morning of 9 April 1871.[5] Following her arrival, she was designated flagship of the Victorian navy.[19] At the time of her arrival, public opinion of the ship was low, and she quickly attracted the nickname of 'Floating Gasometer'.[18]

In 1881, five men from Cerberus were killed when their boat hit a mine during exercises.[8] These were the only personnel from the ship to be killed during her operational history.[8] Following the flooding of the New Australasian Gold Mine at Creswick, Victoria in December 1882, two divers from Cerberus were sent to help find miners trapped in air pockets deep in the mine.[20] They arrived on 14 December, two days after the flooding, but could not assist because incorrectly-fitting dive suits had been sent with them, and only 500 feet (150 m) of air hose was available, despite the miners being at least 1,500 feet (460 m) from the mine's enterance.[21]

The ship was fitted with torpedo netting and spars in 1887.[22] At some point in the 1890s, Cerberus was retasked as a storeship.[18] In May 1900, one of the ship's company began to show the symptoms of the bubonic plague.[23] Consequently, all of Cerberus' personnel were quarantined at Point Nepean.[23]

Following the Federation of Australia in 1901, Cerberus, like all other colonial naval ships, was transferred to the Commonwealth Naval Forces.[16] This organisation was renamed the Royal Australian Navy in 1911, at which point, Cerberus was given the prefix HMAS.[5] By 1909, Cerberus could not generate enough steam to propel herself.[24] She was used as a guard ship and munitions storeship during World War I.[8] When the Royal Australian Naval College was founded in 1913, its personnel were initially listed on the paybooks of Cerberus, as the college was not a commissioned establishment.[25] By 1914, the monitor's main guns were inoperable, and she was reliant on her light weapons for defence.[26]

Following the transfer of six J class submarines to the RAN, Cerberus was renamed HMAS Platypus II on 1 April 1921 (taking her name from the submarine tender HMAS Platypus) and reclassified as a secondary submarine tender.[16][26] Between this date and the monitor's departure form service in 1924, HMAS Protector took the name Cerberus and was attached to the training base at Western Port Bay;[27] the base in turn took the name in 1921.

Decommissioning and fate

Cerberus was sold to the Melbourne Salvage Company for £409 on 23 April 1924, with the buyer to break her up for scrap.[8][5][26] After the salvage company removed what they could, she was then sold on to the Sandringham council for £150.[12] The monitor was scuttled on 26 September 1926 at Half Moon Bay to serve as a breakwater for the Black Rock Yacht Club.[16][19] During her life, Cerberus never left Port Philip Bay, and never fired in anger.[8][28]

The wreck sits in approximately 10 feet (3.0 m), less than 650 feet (200 m) from shore.[2] Over time, the breakwater became a popular site for scuba diving.[29] The interior of the ship has also seen use as a training course for assault swimmers.[29] Her exposed decks were regularly used for picnics.[2]

During the 1970s, the Cerberus Protection Trust was formed to study the feasibility of raising and restoring Cerberus.[30] However, by 1983, the Trust had made little apparent progress.[31]

In 1993, there was a major structural collapse after rusting deck supports and staunchions gave way, leaving only the deck beams to support the deck, turrets, and superstructure.[2] Cerberus began to subside at 16 millimetres (0.63 in) per year.[32] Following this, a 100 metres (330 ft) exclusion zone was placed around the wreck.[2]

In October 2004, the Victorian government funded the A$80,000 removal of the four 18-ton guns from Cerberus, to reduce the load placed on the monitor's deck.[2] After being coated with preservative and receiving an electrolysis treatment, the guns were placed on the seabed next to the wreck.[2] From late 2005, the "Friends of the Cerberus" organisation began to campaign for A$5.5 million in funding to stabilise the wreck site, first by installing additional supports for the deck and turrets (the latter weighing 200 tons each), then raising the ship off the seabed and placing her in an underwater cradle.[2][33] To help attract funds from the Federal and Victorian governments, the wreck was nominated for heritage listing, which was achieved on 14 December 2005.[2][12] In July 2008, AU$500,000 of federal funding was made available to the National Trust of Victoria to start work on the jacking frame and support platform.[32]
