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.

[2] N.9 was a compact biplane with single-bay wings of unequal span that folded back for shipboard stowage.

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.
