Manufacturer	Fairey Aviation Company
First flight	5 July 1917
Status	Prototype
Number built	1

The Fairey N.9 (also known as the F.127) was a British experimental floatplane of the First World War; only one was built. It carried out the first shipborne catapult launches from Royal Navy ships, and was later sold to Norway.

Development and design

In 1917 Fairey Aviation produced two separate designs to meet Admiralty Specification N.2(a) for a two-seat carrier-based seaplane for the Royal Naval Air Service, one powered by a Rolls-Royce Falcon engine, and a larger aircraft powered by a more powerful Sunbeam Maori. The smaller aircraft, usually known by its serial number N.9, but also by its constructor's number F.127, flew first on 5 July 1917,^[1] with the larger aircraft (serial number N.10), the prototype Fairey III, flying in September.^[2]

N.9 was a compact biplane with single-bay wings of unequal span that folded back for shipboard stowage. It was fitted with trailing edge flaps on both the upper and lower wings. Power was from a 200 hp (149 kW) Rolls-Royce Falcon engine with radiators on each side of the engine.^[3]

Its performance was below the requirements of the specification, and no production followed.^[4]

Operational history

Although not chosen for production, N.9 was chosen for trials of catapult launching. After strengthening, it was sent to the Port Victoria Marine Experimental Aircraft Depot for tests with the catapult trials ship, HMS Slinger in June 1918, carrying out the first catapult launches of a seaplane from a Royal Navy ship.^[5]

N.9 was bought back from the Royal Navy and fitted with a Maori engine and equal span wings. It was sold to the Royal Norwegian Navy in May 1920, then sold for civil use in 1927, and wrecked in a crash on 12 June 1928.^[6]
