Supermarine Nanok Aircraft Information

Supermarine Nanok

Manufacturer: Supermarine
First flight: 21 June 1927
Retired: 1934
Number built: 1
Developed from: Supermarine Southampton

The Supermarine Nanok was a British three-engined biplane flying boat built by Supermarine. Built to meet a Royal Danish Navy requirement, the single prototype was rebuilt as a private air yacht and renamed the Supermarine Solent.

Development and design

The Nanok (Inuit language: "Polar bear") was a three engined development of Supermarine's successful Southampton flying boat, designed to meet a Danish requirement for a torpedo carrying flying boat. A prototype was ordered on 17 June 1926, and the aircraft first flew on 21 June 1927. Testing was disappointing, and despite modifications the aircraft could not meet the specified performance and was rejected by the Danes.

The aircraft was therefore converted to a luxury 12-seat civil transport for the use of the Irish brewing magnate, Arthur Ernest Guinness, being renamed the Supermarine Solent.

Operational history

The Solent was certified as airworthy on 5 September 1928, and was used to fly frequently between England and the owner's home near Lough Corrib in County Galway, Ireland. It remained in use until it was scrapped in 1934.
