A low-set cabin contained the wheel-house, chart room and a sickbay. For defence against enemy aircraft, on top of the cabin were two aircraft-style turrets made by Armstrong-Whitworth initially with a single .303 in Vickers K gun or Lewis gun (later improved to paired guns of the same calibre). The mahogany[2] hull was of the hard chine, planing type.
Usageedit
During the Second World War, the retrieval of pilots and aircrew who had been shot down over, or who had had to ditch in, the sea around the British Isles was the responsibility of the Royal Air Force Marine Branch, (motto: "The sea shall not have them"). Rescue of downed aircrew was coordinated using RAF aircraft, aircraft operated by Coastal Command and the Royal Navy and rescue launches operated by the RAF Marine Branch and the Royal Navy.
The Type Two was supplied to RAF marine craft units from the middle of 1940. In total, 69 craft were manufactured between 1940 and 1942.
After World War II, a number of the Type Two craft were transferred to the Royal Navy and a small number were given to the Italian Air Force. The vast majority of the Type Two craft belonging to the Admiralty were subsequently stored and later sold off as houseboats. None are currently owned by any museum or trusts.
Variantsedit
Following their performance during the Dieppe raid in August 1942, the Type Two was modified. Extra armament was fitted – paired .303 in machine guns mounted either side of the wheel-house and a single 20 mm Oerlikon on the (strengthened) rear deck. Protection was improved by adding anti-shrapnel padding around the forward cabin area.
