Australia, Britain, and New Zealand used the Supermarine Walrus.
The Walrus became operational in 1936.
On November 18, 1940, a Walrus was launched from the cruiser HMS Dorsetshire to bomb Somaliland.
The Royal Navy's Fleet Air Arm deployed the Walrus as a shipborne observation aircraft. The Walrus would be catapulted from Royal Navy cruisers and battleships. The Australians and New Zealanders also used the Walrus as a shipborne aircraft.
Search and Rescue
The Royal Air Force (RAF) used the Walrus to rescue shot down pilots. It is estimated that the Walrus saved around 5,000 pilots shot down around Britain and 2,500 in the Mediterranean.
The first full scale air sea rescue operations began in October 1941.
15 squadrons of Walruses were based in the Azores, Britain, France, Iraq, Italy, Malta, North Africa, Sardinia, Sicily, and Singapore.
