British Indian Ocean Territory

The British Indian Ocean Territory (BIOT) is an Overseas Territory of the United Kingdom situated in the Indian Ocean, halfway between Tanzania and Indonesia. The territory comprises the seven atolls of the Chagos Archipelago with over 1,000 individual islands, many very small, amounting to a total land area of 60 square kilometres (23 square miles).[2] The largest and most southerly island is Diego Garcia, 27 square kilometres (10 square miles), the site of a Joint Military Facility of the United Kingdom and the United States.[5] Official administration is remote from London,[6][7] though the local capital is often regarded as being on Diego Garcia.[8]

The only inhabitants are British and United States military personnel, and associated contractors, who collectively number around 3,000 (2018 figures).[2] The forced removal of Chagossians from the Chagos Archipelago occurred between 1968 and 1973. The Chagossians, then numbering about 2,000 people, were expelled by the UK government to Mauritius and Seychelles, even from the outlying islands far away from the military base on Diego Garcia. Today, the Chagossians are still trying to return, but the UK government has repeatedly denied them the right of return despite calls from numerous human rights organizations to let them.[9][10] The islands are off-limits to Chagossians, tourists, and the media.


Since the 1980s, the Government of Mauritius has sought to regain control over the Chagos Archipelago, which was separated from the then Crown Colony of Mauritius by the UK in 1965 to form the British Indian Ocean Territory. A February 2019 advisory opinion of the International Court of Justice called for the islands to be given to Mauritius. Since this, the United Nations General Assembly and the International Tribunal for the Law of the Sea have reached similar decisions. On 3 November 2022, it was announced that the UK and Mauritius had decided to begin negotiations on sovereignty over the British Indian Ocean Territory, taking into account the international legal proceedings.[11]

Naval Party 1002 and MV Grampian Frontier[edit]

Naval Party 1002 (NP 1002) is directly present in the territory, and is composed of both Royal Navy and Royal Marine personnel. NP 1002 is responsible for civil administration and enforcement. Its members are tasked with policing and carrying out customs duties. Royal Marines in the territory also reportedly form a security detachment.[49]


Prior to 2017, the BIOT patrol vessel, MV Pacific Marlin, was based in Diego Garcia. It was operated by the Swire Pacific Offshore Group. The Pacific Marlin patrolled the marine reserve all year, and since the marine reserve was designated in April 2010, the number of apprehensions of illegal vessels within the area has increased. The ship was built in 1978 as an ocean-going tug. It is 57.7 metres (189 feet 4 inches) long, with a draught of 3.8 metres (12 feet 6 inches), and gross tonnage of 1,200 tons. It has a maximum speed of 12.5 knots (23.2 kilometres per hour; 14.4 miles per hour) with an economic speed of 11 knots (20 kilometres per hour; 13 miles per hour), permitting a range of about 18,000 nautical miles (33,000 kilometres; 21,000 miles) and fuel endurance of 68 days. It was the oldest vessel in the Swire fleet.[50] Pacific Marlin reportedly spent about 54% of her taskings on fishery patrol duties, and a further 19% on military patrol duties.[51]


In 2016, a new contract was signed with Scottish-based North Star Shipping for the use of the vessel MV Grampian Frontier. She is a 70 metres (230 feet) vessel carrying up to 24 personnel, and fulfils both the patrol and research role.[51] The vessel reportedly operates in conjunction with personnel from NP 1002 on both fisheries and military enforcement tasks / exercises, and also carries scientists / researchers involved in a range of research work, particularly conservation.[52] In 2022, Grampian Frontier tracked a Mauritian-charted vessel temporarily bringing Chagossian exiles to Blenheim Reef in the archipelego.[53]


The Royal Navy also maintains two offshore patrol vessels in the Indo-Pacific region, HMS Tamar and HMS Spey. Either may be periodically employed for sovereignty protection and other duties in BIOT waters.[54][55] HMS Tamar paid a rare visit to the islands in February/March 2023 conducting fisheries protection and other missions.[56]
