 On 1 September 1965, during the Indo-Pakistani War, No.45 Squadron IAF responded to a request for strikes against a counter-attack by the Pakistani Army (Operation Grand Slam), and twelve Vampire Mk 52 fighter-bombers were successful in slowing the Pakistani advance.However, the Vampires encountered two Pakistan Air Force (PAF) F-86 Sabres, armed with air-to-air missiles; in the ensuing dogfight, the outdated Vampires were outclassed.
