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.
