Supermarine Southampton

The Supermarine Southampton was a twin-engine biplane flying boat and first entered service with the Royal Air Force (RAF) in 1925. It was a sturdy, reliable aircraft, nicknamed "Old Faithful" by its crew. The original production model, Mk I, of the Southampton had a wooden hull, but the Mk II was manufactured with a metal hull to save the weight caused by water absorption. Only 78 Southamptons were produced, and the type served with the RAF until 1936.

Two Mk I Southamptons were ordered for the RAAF's Coastal Reconnaissance Flight in June 1927 and entered service in May 1928. One of the aircraft was sold in 1937 and the other remained in service until 1940, being employed by the Seaplane Training Flight and, briefly, by 10 Squadron.
