History

The original seaplane base was established during
World War I World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fightin ...
, in 1917, as HMS ''Sarepta''. The station used floatplanes, which flew coastal patrols to protect shipping from German U-boat attacks. In August 1918 HMS ''Sarepta'' was taken over by the RAF, and a larger unit of 12 aircraft was formed as

. Following the Armistice in November 1918, the squadron was disbanded and aviation operations ceased at Portland in 1919. Following the inter-war period, a Fleet Requirements Unit, 772 Squadron, arrived at Portland in September 1939 and stayed until July 1940. With the fall of France early in the war, the Naval Base at Portland became a prime target for the

. As a result, HMS ''Osprey'' was moved to Cambeltown in July 1940, taking 772 Squadron with it, and leaving Portland's base to remain under Care and Maintenance. After the war HMS ''Osprey'' returned to Portland and a helicopter base became an important centre for the school to perform experiments and development. In 1946

Bs moved in and the success of their trials at Portland led the Admiralty to replace fixed-wing aircraft with helicopters for use in the fleet. A major building programme followed at Portland, with the base's playing fields taken over as a landing ground, while the old fleet canteen was converted into a headquarters building, containing the operations centre, a workshop and control tower. During the late 1950s the marshy area known as the Mere was filled in and built over, and later expansion meant that this tidal lagoon was completely covered. This created a large concreted area to produce the modern, large helicopter facility. Upon the completion of the work, 815 Naval Air Squadron flew its 12 Westland Whirlwinds to the new Portland Heliport on 14 April 1959. The station was formally commissioned as HMS ''Osprey'' on 24 April 1959. For the next 40 years RNAS Portland was one of the busiest air stations on the south coast. As a helicopter development and training base, it was largely responsible for training aircrew in anti-submarine operations. The site of the base was gradually improved over the years, with considerable expansion in the 1960s and 1970s, notably between 1967 and 1970, with new hangars. With the reduction of armed forces, Portland's naval base closed on 29 March 1996, with the Flag Officer Sea Training ( FOST) moving to Plymouth's ( HMS ''Drake''). With this RNAS Portland became surplus to requirements, leading to its eventual closure on 31 March 1999. RNAS Portland held its final open day for the public on 17 October 1998. Following the closure of the base, the 80-acre site was renamed Osprey Quay in 2001, as part of the site's regeneration project. The

Aside from the academy, the site offered over 11 hectares of business space, along with a new Dean & Reddyhoff Marina, Portland Marina. The redevelopment of the station's former Helicopter Control Tower has also been announced. With the removal of the Coastguard Helicopter Service from Portland on 1 July 2017 the site once again become surplus to requirements and in October 2016 the formal process for the disposal of the site was commenced by the Homes & Communities Agency.
