Because of increased demand, F.4 production was divided between Gloster and Armstrong Whitworth. The majority of early F.4s did not go to the RAF: 100 were exported to Argentina, seeing action on both sides in the 1955 revolution; in 1947, only RAF Nos. 74 and 222 squadrons were fully equipped with the F.4. Nine further RAF squadrons converted from 1948 onwards. From 1948, 38 F.4s were exported to the Dutch, equipping four squadrons (322, 323, 326 and 327) split between bases in Soesterberg and Leeuwarden until the mid-1950s. In 1949, only two RAF squadrons were converted to the F.4, Belgium was sold 48 aircraft in the same year (going to 349 and 350 squadrons at Beauvechain) and Denmark received 20 over 1949–1950. In 1950, three more RAF squadrons were upgraded, including No. 616 and, in 1951, six more.
