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:
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 HMS Tyne 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.
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.
Strategic Command (UKStratCom) is a tri-service organisation managing allocated joint capabilities from the three armed services.
Permanent Joint Headquarters (PJHQ) is a tri-service organisation holding Operational Control of British armed forces joint military operation. PJHQ is headed by the Chief of Joint Operations. Single-service operations remain under the operational control of the appropriate front-line command.
The Commander Operations remains with the current operations staff on the Northwood site. Among Commander Operations' responsibilities are command of Commander Task Force (CTF) 311 (UK attack submarines) and CTF 345 (UK nuclear missile submarines).
Reservists from HMS Wildfire, part of the Royal Naval Reserve, who had moved from the Northwood Headquarters site to Brackenhill House on Oxhey Drive South in 1988, moved back into a new building on the Northwood Headquarters site in June 2011.
