 The Mk. VI had a brief overseas career. One of the early units was experimentally fitted to a Hurricane Mk. IIc, and this led to a production of a single flight of such designs starting in July 1942. These conversions were given such a low priority that they were not complete until the spring of 1943. Some of these aircraft were sent to Calcutta where they claimed a number of Japanese bombers. An experimental fit on Hawker Typhoon iA R7881 was carried out, with the system packed into a standard underwing drop tank. This was available in March 1943 and underwent lengthy trials lasting into 1944, but nothing came of this work.
