The Typhoon FR IB was developed in early 1944 and was used as a tactical reconnaissance fighter. In this version the port inner cannon was removed and three (one forward-facing and two vertical five-inch) F24 cameras were carried in its place. Few FR IBs were built, and most served with 268 Squadron, starting in July 1944. The aircraft was never popular with the pilots, who preferred the older Mustang Is and IAs, and the inherent engine and airframe vibrations meant that photos were invariably blurred. As a consequence of these problems, the FR IB was phased out in January 1945.
