context_page_description: RNAS Calshot was a First World War Royal Navy air station for seaplanes and flying boats, mainly operating as an experimental and training station, but also providing anti-submarine and convoy protection patrols.
  It was located at the end of Calshot Spit in Southampton Water, at grid reference SU487024, with the landing area sheltered by the mainland, to the west, north and east, and the Isle of Wight a few miles away to the south on the other side of the Solent.
context_section_description: In July 1914 the Royal Navy re-formed its air branch, naming it the Royal Naval Air Service (RNAS), and took over the Calshot base and its development and training functions. After the start of World War I, the station's role expanded to take on the protection of shipping in the English Channel, and a variety of flying-boats and seaplanes were introduced, including the Wight Seaplane and the Short 184. Calshot was also used for training on observer kite balloons and airships.
  In 1917, seaplane training was extended to the new Naval Seaplane Training School at nearby Lee-on-the-Solent. A major rebuild at Calshot then took place when new buildings, offices and workshops were constructed by the Henry Boot Limited. The largest hangar – Sunderland Hangar – is now home to the Calshot Activities Centre.
  By 1918 there were two flights of Felixstowe flying boats and a flight of seaplanes, and together they managed to exceed 9,000 hours of patrol flights in a three-month period. Out of 42 U-boats reported, 3 were sunk.
