HMAS AE1 was an E-class submarine of the Royal Australian Navy (RAN). She was the first submarine to serve in the RAN, and sank with all hands near what is now East New Britain, Papua New Guinea, on 14 September 1914, after less than seven months in service. Search missions attempting to locate the wreck began in 1976. The submarine was found during the 13th search mission near the Duke of York Islands in December 2017.
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 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.
Kaikō was a remotely operated underwater vehicle (ROV) built by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) for exploration of the deep sea. Kaikō was the second of only five vessels ever to reach the bottom of the Challenger Deep, as of 2019. Between 1995 and 2003, this 10.6 ton unmanned submersible conducted more than 250 dives, collecting 350 biological species, some of which could prove to be useful in medical and industrial applications. On 29 May 2003, Kaikō was lost at sea off the coast of Shikoku Island during Typhoon Chan-Hom, when a secondary cable connecting it to its launcher at the ocean surface broke.
An autonomous underwater vehicle (AUV) is a robot that travels underwater without requiring continuous input from an operator. AUVs constitute part of a larger group of undersea systems known as unmanned underwater vehicles, a classification that includes non-autonomous remotely operated underwater vehicles (ROVs) – controlled and powered from the surface by an operator/pilot via an umbilical or using remote control. In military applications an AUV is more often referred to as an unmanned undersea vehicle (UUV). Underwater gliders are a subclass of AUVs.
A deep-submergence rescue vehicle (DSRV) is a type of deep-submergence vehicle used for rescue of personnel from disabled submarines and submersibles. While DSRV is the term most often used by the United States Navy, other nations have different designations for their equivalent vehicles.
The Royal Australian Navy, although a significant force in the Asia-Pacific region, is nonetheless classed as a medium-sized navy. Its fleet is based around two main types of surface combatant, with limited global deployment and air power capability. However, in 2009, a white paper, Defending Australia in the Asia Pacific Century: Force 2030, was produced by the Australian government which set out a programme of defence spending that will see significant improvements to the RAN's fleet and capabilities. In recent times, Australia released its Surface Fleet Review in 2024, which analyses the future of the RAN and shows what the Government will procure.
The Duke of York Islands are a group of islands located in East New Britain Province, Papua New Guinea. They are found in St George's Channel between New Britain and New Ireland islands and form part of the Bismarck Archipelago. The Duke of York Islands were named in 1767 by Philip Carteret to honour Prince Edward, son of Frederick, Prince of Wales and younger brother of George III of the United Kingdom.
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.

A submarine rescue ship is a surface support ship for submarine rescue and deep-sea salvage operations. Methods employed include the McCann Rescue Chamber, deep-submergence rescue vehicles (DSRV's) and diving operations.
Australian Border Force Cutter (ABFC) Ocean Shield is an offshore patrol vessel operated by the Australian Border Force. The ship was originally ordered in 2010 by DOF Subsea as an offshore support vessel, and was laid down by STX OSV as MSV Skandi Bergen in 2011. In 2012, the Australian Department of Defence was seeking a short-term replacement for the decommissioned Kanimbla-class amphibious landing ships, and negotiated to purchase the under-construction Skandi Bergen from DOF Subsea. The ship was completed, and entered Royal Australian Navy (RAN) service in mid-2012 as the civilian-crewed Australian Defence Vessel (ADV) Ocean Shield.
The disappearance of Malaysia Airlines Flight 370 led to a multinational search effort in Southeast Asia and the southern Indian Ocean that became the most expensive search in aviation history.
The timeline of Malaysia Airlines Flight 370 lists events associated with the disappearance of Malaysia Airlines Flight 370—a scheduled, commercial flight operated by Malaysia Airlines from Kuala Lumpur International Airport to Beijing Capital International Airport on 8 March 2014 with 227 passengers and 12 crew. Air traffic control lost contact with Flight 370 less than an hour into the flight, after which it was tracked by military radar crossing the Malay Peninsula and was last located over the Andaman Sea. Analysis of automated communications between the aircraft and a satellite communications network has determined that the aircraft flew into the southern Indian Ocean, before communication ended shortly after 08:19 (UTC+8:00). The disappearance initiated a multi-national search effort that became the most expensive search in aviation history.
The MV Havila Harmony is a multi-role, dynamically-positioned support vessel built in 2005 for subsea construction and support operations. The vessel is owned by Havila Shipping and currently on long-term charter to Fugro.
RV Petrel, or R/V Petrel, is a 76.45 m (250.8 ft) research vessel sailing under the UK flag and owned by the United States Navy and once owned by Microsoft co-founder Paul Allen. The ship is named after the petrel, a sea bird. The ship was completed by Brattvaag Skipsverft, Norway in 2003 as the deepwater offshore inspection vessel Seaway Petrel for service with Stolt Offshore. She was later renamed Acergy Petrel, then Seven Petrel with Subsea 7.
Seabed Constructor is a multipurpose offshore vessel owned by Swire Seabed and contracted since December 2016 to British-owned hydrographic survey company Ocean Infinity, based in Houston, Texas, United States. Previously known as Olympic Athene and originally Olympic Boa, the ship was launched in 2013 and is flagged in Norway. The ship is designed to conduct geophysical and geotechnical surveys of the seabed, support the construction or demolition of underwater structures, conduct trenching and excavation operations, and serve as a ROV platform for the company's autonomous underwater vehicles and unmanned surface vehicles. The ship is 114 metres (374 ft) in length, with a 22 metres (72 ft) beam, a gross tonnage of 7,883, and deadweight tonnage of 6,480 metric tons. Its maximum speed is 14.1 knots.
