RAF Coastal Area was a formation within the Royal Air Force (RAF). Founded in 1919, it was to act as the RAF's premier maritime arm. It was replaced by RAF Coastal Command on 14 July 1936. Beginnings of maritime aviation The Committee of Imperial Defence (CID) met in 1909 and decided the direction that British air power would take in the early 20th century. As far as maritime air power was concerned, First Sea Lord of the Admiralty Winston Churchill, an advocate of the aircraft in military affairs, pushed for development. Under pressure from the services, both the Royal Navy and British Army, the Government increased spending and the aviation budget rose from £9,000 in 1909 to £500,000 by 1913. Before the First World War the Naval Staff had a positive attitude to aviation and their interests were to grow during the course of the 1914–1918 conflict. Before the war budgetary concerns and constraints had kept the development of aviation low. While the War Office attempted to save money by encouraging civilian aviators such as Samuel Cody to carry out research on their behalf, mostly in the field of reconnaissance and artillery co-operation, the Admiralty undertook its own trials with aircraft built to its own specifications. Between 1909 and 1911 the Navy took advantage of huge strides in military development of aircraft, having a significant tradition in research and development and a strong regard to long-range navigation and reconnaissance. Attention swiftly turned to ship-borne aircraft. Lieutenant Charles Rumney Samson achieved the feat of flying off a ship in December 1911. On 2 January 1912 Lieutenant H.A Williamson, a submarine officer, who held a Royal Aero Club Certificate submitted a paper dealing with ship-borne aircraft and their use for anti-submarine warfare (ASW). The Royal Naval Air Service (RNAS) factored these aspects of naval air warfare into its development of naval aviation. The Navy was quick to begin experiments to see if surface vessels and submarines could be detected from the air, and started this research in July 1912 at Harwich and Rosyth. The use of wireless telegraphy and bomb dropping was well in advance of the War Office. The Royal Flying Corps (RFC) carried out bomb dropping experiments but refused to respond to Admiralty requests for collaboration, this was as late as August 1914. The Naval Air Wing was renamed the RNAS officially in July 1914 and affirmed its independence from
