HMAS Platypus is a former Royal Australian Navy (RAN) submarine base, located at 118 High Street, North Sydney with moorings in Neutral Bay, a suburb of Sydney in New South Wales, Australia. It was located upon the site of the Royal Australian Navy Torpedo Maintenance Establishment (RANTME), it built on the site of the former North Sydney Gas Works that operated on the site from 1877 and resumed by the Commonwealth in 1942. [1] The Fleet Intermediate Maintenance Activity (FIMA) Workshops building on the site was originally used for torpedo assembly and storage during World War 2. It was later modified for submarine maintenance and repair, with a steel tower added to the northern end of the building for testing, cleaning and maintenance of periscopes.
HMAS Platypus was commissioned on 18 August 1967, conjointly with the Royal Navy Fourth Submarine Squadron as the eastern Australian base for the six RAN Oberon-class submarines. The first of the Australian Oberon-class submarines arrived from the United Kingdom the day Platypus was commissioned into the Royal Australian Navy, HMAS Oxley. [2] [3] Over its years of operation, Platypus has provided home base for the First Australian Submarine Squadron (later the Australian Submarine Squadron), including Oxley, Otway, Ovens, Onslow, Orion and Otama, as well as the Royal Navy's HMS Trump, Tabard and Odin. [4]
Platypus, which was referred to as "Plats" by the ship's company, was the only dedicated submarine base in Australia. Engineering workshops, medical facilities, the submarine school, communications centre and administration were all housed at the base providing the operational support required for the six submarines and their crews. While the submarines operated from the waterfront, the RAN's torpedo workshops occupied the southern part of the site.
In 1999, Platypus and the torpedo workshops closed down when the Australian Government relocated its submarine base to HMAS Stirling in Western Australia. Platypus was decommissioned on 14 May 1999. [4]
The site was handed over to the Sydney Harbour Federation Trust (SHFT) on 23 July 2005, and is partially open to public. The SHFT has carried out extensive works on site since 2010 including remediation of ground contamination and buildings. The first stage of the remediation project included above ground works, demolition of the three storey Administration Building at the north of the site and part of the wharf, removal of hazardous materials, repairs to the seawall and remaining wharf. A large odour control enclosure, an emission control system and water treatment plant were constructed for the remediation works. Around 3,000 tonnes of tar–containing materials were excavated and removed by barge for off–site disposal. An additional 27,000 tonnes of material remained for on–site treatment and stabilisation. The remaining material was then used to backfill the excavated area and to create a mound capped with clean soil, forming the base for the public park at the northern end of the site. In May 2018 public access was provided to the foreshore areas and northern park via a new pedestrian walkway from Kesterton Park to the south, and a new staircase linking to Kiara Close at the north of the site.
The Trust's board approved the Platypus Management Plan in December 2016 and the site is being remediated and refurbished to allow future public access. [5] In August 2017 it was announced that the site will be opened to the public in mid-2018, to be known as Sub Base Platypus and 'providing a range of facilities and venues for cultural performances, function areas, cafes and restaurants, as well as offices and commercial spaces. Sailing’s national sporting Australian Sailing is locating its office and training facility here early in 2020'. [6]
During 2016, parts of the site were used for the recording of the television series, season eleven of The Biggest Loser.
On 18 August 2017 a 50th Anniversary and Submariners Memorial dedication ceremony took place in the Northern Park, now known as Oberon Park. The official party included Minister for Defence Marise Payne and former commanding officers. The service dedicated a memorial that features a restored anchor from HMAS Oxley, sitting on a circular precast concrete plinth. [7]
HMAS AE2 was an E-class submarine of the Royal Australian Navy (RAN). One of two submarines ordered for the fledgling navy, AE2 was built by Vickers Armstrong in England and was commissioned into the RAN in 1914. Together with her sister submarine, HMAS AE1, the boat then sailed to Australia in what was, at the time, the longest voyage ever undertaken by a submarine.
HMAS Onslow is one of six Oberon-class submarines, previously operated by the Royal Australian Navy (RAN). The submarine was named after the town of Onslow, Western Australia, and Sir Alexander Onslow, with the boat's motto and badge derived from Onslow's family heritage. Ordered in 1963, Onslow was laid down at the end of 1967 by Scotts Shipbuilding and Engineering Company in Scotland, launched almost a year later, and commissioned into the RAN at the end of 1969.
HMAS Orion was an Oberon-class submarine of the Royal Australian Navy (RAN). One of six submarines ordered by the RAN during the 1960s, Orion, named after the constellation in a break from ship-naming tradition, was built in Scotland and commissioned in 1977. Orion was one of two Oberon-class submarines designed for intelligence gathering and conducted regular patrols in Soviet, Indian and Chinese waters to gather information regarding enemy capabilities.
HMAS Otama was an Oberon-class submarine, formerly of the Royal Australian Navy (RAN). Built in Scotland, the submarine was the last of the class to enter service when commissioned into the RAN in 1978. Otama was a specialist, one of two "Mystery Boats", fitted with additional surveillance and intelligence-gathering equipment. Otama was routinely deployed on classified operations to obtain intelligence on Soviet Pacific Fleet vessels and Chinese Navy vessels, and conducted associated coastal surveillance, throughout Asia.
HMAS Ovens is an Oberon-class submarine, formerly of the Royal Australian Navy (RAN). She was one of six Oberons built for the Royal Australian Navy by the Scottish Scotts Shipbuilding and Engineering Company, and entered service in 1969. The vessel was named for Irishman and Australian explorer John Ovens (1788–1825) and for whom the Victorian river Ovens was named. During her career, Ovens was the first RAN submarine to deploy with the ANZUK force, and the first RAN submarine to fire an armed Mark 48 torpedo, sinking the target ship Colac. The boat was decommissioned in 1995, and is preserved at the Western Australian Maritime Museum as a museum ship.
The Oberon class was a ship class of 27 British-designed submarines operated by five nations. They were designed as a follow-on from the Porpoise class; physical dimensions were the same but stronger materials were used in hull construction and improved equipment was fitted.
HMS Trump was a British submarine of the third group of the T class. She was built by Vickers-Armstrongs, Barrow, and launched on 25 March 1944. So far she has been the only ship of the Royal Navy (RN) to bear the name Trump. She spent the majority of her life attached to the 4th Submarine Squadron based in Australia. She was kept in service following the war and was refitted for greater underwater performance, and was the final RN submarine to be posted in Australia, departing in January 1969. She was sold off and broken up for scrap in August 1971.
The Collins-class submarines are Australian-built diesel-electric submarines operated by the Royal Australian Navy (RAN). The Collins class takes its name from Australian Vice Admiral John Augustine Collins; each of the six submarines is named after significant RAN personnel who distinguished themselves in action during World War II. The six vessels were the first submarines built in Australia, prompting widespread improvements in Australian industry and delivering a sovereign sustainment/maintenance capability.
The Cockatoo Island Dockyard was a major dockyard in Sydney, Australia, based on Cockatoo Island. The dockyard was established in 1857 to maintain Royal Navy warships. It later built and repaired military and battle ships, and played a key role in sustaining the Royal Australian Navy. The dockyard was closed in 1991, and its remnants are heritage listed as the Cockatoo Island Industrial Conservation Area.
From 31 May to 8 June 1942, during World War II, Imperial Japanese Navy submarines made a series of attacks on the Australian cities of Sydney and Newcastle. On the night of 31 May – 1 June, three Ko-hyoteki-class midget submarines, each with a two-member crew, entered Sydney Harbour, avoided the partially constructed Sydney Harbour anti-submarine boom net, and attempted to sink Allied warships. Two of the midget submarines were detected and attacked before they could engage any Allied vessels. The crew of M-14 scuttled their submarine, whilst M-21 was successfully attacked and sunk. The crew of M-21 killed themselves. These submarines were later recovered by the Allies. The third submarine attempted to torpedo the heavy cruiser USS Chicago, but instead sank the converted ferry HMAS Kuttabul, killing 21 sailors. This midget submarine's fate was unknown until 2006, when amateur scuba divers discovered the wreck off Sydney's northern beaches.
HMAS Albatross is the main naval air station for the Royal Australian Navy's (RAN) aviation branch, the Fleet Air Arm. The base, located near Nowra, New South Wales, was formally established in May 1942 as Royal Australian Air Force (RAAF) base RAAF Nowra, then was transferred to the Royal Navy as HMS Nabbington in 1944, and operated as a naval air station until it was decommissioned in late 1945. In 1948, the airfield was commissioned into the RAN as HMAS Albatross, as the primary shore base for the Fleet Air Arm. Since 2011, five squadrons of the Fleet Air Arm operate from Albatross. The current commander of the base is Captain Robyn Phillips, RAN.
HMAS Penguin is a Royal Australian Navy (RAN) base located at Balmoral on the lower north shore of Sydney Harbour in the suburb of Mosman, New South Wales. Penguin is one of the RAN's primary training establishments, with a responsibility for providing trained specialists for all areas of the navy. The current commander of Penguin is Commander Kent Browning, RAN.
Fleet Base East is a Royal Australian Navy (RAN) major fleet base that comprises several naval establishments and facilities clustered around Sydney Harbour, centred on HMAS Kuttabul. Fleet Base East extends beyond the borders of Kuttabul and includes the commercially-operated dockyard at Garden Island, and adjacent wharf facilities at nearby Woolloomooloo, east of the Sydney central business district in New South Wales, Australia. Fleet Base East is one of two major facilities of the RAN, the other facility being Fleet Base West. The fleet operates in the Pacific Ocean.
The history of the Royal Australian Navy traces the development of the Royal Australian Navy (RAN) from the colonisation of Australia by the British in 1788. Until 1859, vessels of the Royal Navy made frequent trips to the new colonies. In 1859, the Australia Squadron was formed as a separate squadron and remained in Australia until 1913. Until Federation, five of the six Australian colonies operated their own colonial naval force, which formed on 1 March 1901 the Australian Navy's (AN) Commonwealth Naval Force which received Royal patronage in July 1911 and was from that time referred to as Royal Australian Navy (RAN). On 4 October 1913 the new replacement fleet for the foundation fleet of 1901 steamed through Sydney Heads for the first time.
The Royal Australian Navy Heritage Centre is the maritime museum of the Royal Australian Navy. The centre opened on 4 October 2005 and is located within the Public Access Area on the northern end of the Garden Island naval base in Sydney. Since 2021, it has been temporarily closed due to redevelopment of the public-access ferry wharf.
The Royal Australian Navy Submarine Service is the submarine element of the Royal Australian Navy. The service currently forms the Navy's Submarine Force Element Group (FEG) and consists of six Collins class submarines.
HMAS Otway was an Oberon-class submarine of the Royal Australian Navy (RAN). One of the first four Oberon-class boats ordered for the RAN, Otway was built in Scotland during the mid-1960s, and commissioned into naval service in 1968. The submarine was decommissioned in 1994. The submarine's upper casing, fin, and stern are preserved at Holbrook, New South Wales.
HMAS Oxley was an Oberon-class submarine of the Royal Australian Navy (RAN).
M24 Japanese Midget Submarine wreck site is a heritage-listed former midget submarine and now archaeological site located in unincorporated waters off Sydney's Northern Beaches in New South Wales, Australia. The Ko-hyoteki-class midget submarine was designed by the Imperial Japanese Navy and built from 1941 to 1942 by Kure Naval Yard or Ourazaki Naval Yard. The site was added to the New South Wales State Heritage Register on 7 December 2007.
The 4th Submarine Squadron was a unit of the Royal Navy operating conventional submarines. It was established at HMAS Penguin, Sydney, Australia, in 1949 partly to provide anti-submarine warfare training to Royal Australian Navy (RAN) and Royal New Zealand Navy personnel. The Royal Navy transitioned to nuclear-powered submarines from 1960 and notified the Australians that the 4th Submarine Squadron would be disbanded. The RAN decided to procure its own submarines to replace the squadron in the training role and purchased four Oberon-class vessels in 1963. To prepare the RAN to maintain these vessels the Royal Navy agreed to refit five T-class submarines, including at least three from the 4th Submarine Squadron, at Cockatoo Island Dockyard in Sydney. The 1st Australian Submarine Squadron was operational by 1969, upon which the Royal Navy disbanded the 4th Submarine Squadron.
