Westland N.1B

Despite good performance, only two aircraft were built, the Royal Naval Air Service operating landplane fighters from ships instead.

In 1916, the British Admiralty drew up Requirement N.1B for a single-seat floatplane or flying boat fighter aircraft to operate from the Royal Navy's seaplane carriers, demanding a speed of 110 mph (177 km/h) and a ceiling of 20,000 ft (6,100 m).

[1] It had a deep fuselage, while its two-bay wings were designed to fold to save space on ship, and were fitted with trailing-edge flaps.

[5] The two N.1Bs were evaluated at the Port Victoria Marine Experimental Aircraft Depot in October 1917,[6] demonstrating good performance and handling.

[5] By this time, however, the Royal Naval Air Service was operating Sopwith Pup landplanes from flying-off platforms aboard ships, which did not require the carrier to heave-to in order to lower a seaplane to the water, and was planning to carry out similar operations with the Sopwith Camel, and the N.1B programme was cancelled.
