Northwood Headquarters is a military headquarters facility of the British Armed Forces in Eastbury, Hertfordshire, England, adjacent to the London suburb of Northwood. It is home to the following military command and control functions: Headquarters, Strategic Command, formerly Joint Forces Command Permanent Joint Headquarters Commander Operations for the Royal Navy NATO Allied Maritime Command History The headquarters is on the grounds of Eastbury Park. In 1938 the Royal Air Force took over the site for the use of RAF Coastal Command which made use of the Eastbury house and also created a network of underground bunkers and operations blocks. The house was used as an Officers' Mess though it was subsequently damaged by fire. In 1953 the Commander-in-Chief, Home Fleet, gained an additional NATO responsibility as Commander-in-Chief, Eastern Atlantic, as part of SACLANT, and the Eastern Atlantic NATO military command structure was established at the Northwood Headquarters. The Commander-in-Chief Home Fleet still flew his flag however in at Portsmouth. In 1960 the Commander-in-Chief Home Fleet moved to Northwood, in 1963 the Naval unit at Northwood was commissioned as HMS Warrior and in 1966 the NATO Channel Command (a post also held by the Commander-in-Chief Home Fleet) moved to Northwood from Portsmouth. The RAF completely vacated the site in 1969. In September 1971, when the post of Commander-in-Chief Fleet was established, the Royal Navy took over responsibility for the whole site and in 1978 the Flag Officer Submarines also moved his Headquarters to Northwood. As Headquarters of the Commander-in-Chief Fleet, the site was the controlling Headquarters for Operation Corporate, the Falklands War, in 1982. The Permanent Joint Headquarters was established on site in April 1996. In 2002, following a rationalisation, the Commander-in-Chief Fleet moved the majority of his staff to Portsmouth and handed over the Northwood site to the Chief of Joint Operations. In 2006 major construction works commenced to improve the functionality of the site: the works, which involved the refurbishment or replacement of many of the key buildings, were carried under a Private Finance Initiative contract by Carillion. The Queen visited the site on 6 May 2010 to open the main Permanent Joint Headquarters building, part of a £150 million redevelopment of the site. Joint Forces Command was established on site in April 2012. On 9 December 2019, it was announced that Joint Forces Command had been renamed as Strategic Command.
