In mid 1952, the Sabre Mk 4 went into production with the first one flown onĀ the 28th August 1952. Apart from some minor structural and system changes, including improved air-conditioning and gun sight, the MK 2 and the MK 4 were identical. The Sabre MK 4’s went directly to the RAF under a mutual aid program, equipping the 11th RAF squadron.
