Question: The HMAS "Platypus" was ordered to support which submarine that ended up getting lost at sea in 1914?
Context: Getting lost is the occurrence of a person or animal losing spatial reference.  This situation consists of two elements: the feeling of disorientation and a spatial component.  Getting lost is a popular expression to explain that someone is in a desperate situation. HMAS "Otway" (S 59) 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 "AE1 (originally known as just AE1") was an "E"-class submarine of the Royal Australian Navy (RAN).  She was the first submarine to serve in the RAN, and was lost at sea with all hands near East New Britain, Papua New Guinea, on 14 September 1914, after less than seven months in service.  The wreck of the submarine has never been found, despite several searches. HMAS "AE2" (originally known as "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 "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).  Following remediation and refurbishment, it is to open for public use as Sub Base Platypus in mid-2018. HMAS "Platypus" was a submarine depot ship and base ship operated by the Royal Australian Navy (RAN) between 1919 and 1946.  Ordered prior to World War I to support the Australian submarines "AE1" and "AE2", "Platypus" was not completed until after both submarines had been lost, and she was commissioned into the Royal Navy from 1917 to 1919. "I Thought I Lost You" is a pop rock song performed by both American singer-songwriter and actress Miley Cyrus and actor and singer John Travolta.  The song was co-written by Cyrus with producer Jeffrey Steele.  It was released to Radio Disney as promotion for the 2008 Disney animated film "Bolt", in which Cyrus and Travolta provide the voices of Penny and Bolt.  "I Thought I Lost You" was made after filmmakers requested Cyrus to write a song for the film.  The lyrics speak of getting lost and getting found. Several ships and shore establishments of the Royal Australian Navy have been named HMAS "Platypus", after the platypus: HMAS "Protector" (ASR 241) was a Royal Australian Navy (RAN) trials and submarine rescue ship.  Built in 1984, the ship was initially operated by the National Safety Council of Australia as MV "Blue Nabilla.  She was purchased by the RAN in 1990 for use as a surveillance, training, and diving support vessel.  During her military career, "Protector" supported the trials of the "Collins"-class submarine s, and was involved in a search for the shipwreck of the World War II cruiser HMAS "Sydney" .  The ship was decommissioned in 1998 and, while still owned by the Commonwealth, she is provided to Defence Maritime Services to allow them to support Navy activities under contract.  Renamed Seahorse Horizon", the ship is operated by Defence Maritime Services out of HMAS "Creswell" as a training and Fleet support vessel. HMS "Tabard" was a British submarine of the third group of the T class.  She was built by Scotts, Greenock, and launched on 21 November 1945.  So far she has been the only boat of the Royal Navy to bear the name "Tabard", after the item of clothing.  Having been launched after the war, she was selected, along with a number of boats of her class, to try out new streamlining techniques based on the German Type XXIII submarine.  In May 1963, she was involved in a collision with HMAS "Queenborough" , and on 10 February 1964 she underwent exercises with HMAS "Melbourne" and HMAS "Voyager" in the hours before their collision.  When she returned to the UK, she became the static training submarine at the shore establishment HMS "Dolphin" , until 1974 when she was sold and broken up.
