The type remains flying into the 2020s, albeit with increasing difficulty due to a decreasing supply of spare parts over time.
[4][5] In the 1960s, the British Aircraft Corporation, which had acquired Hunting Percival, and therefore the Jet Provost, proceeded with the development of a counter-insurgency/light attack derivative of the type, which it designated as the BAC 167.
By this point, it had become apparent that several of the competitions that the Jet Provost had been entered into had decided against the type due to its perceived lack of potential firepower.
[6] It was powered by a single Armstrong Siddeley Viper turbojet, akin to the Jet Provost; however, this engine was uprated to produce up to 3,140 lb (14.0 kN) of thrust.
[7] Furthermore, key areas of the airframe, such as the wings, were stressed to withstand the additional weight incurred by the carriage of a variety of munitions.
[16] A particularly notable engagement occurred during July 1972, which has since been referred to as the Battle of Mirbat; a total of four Omani Strikemasters provided close air support to heavily outnumbered ground forces that were under attack by roughly 300 insurgents.
[18] Following the creation of the Botswana Defence Force Air Wing in April 1977 amid escalating regional tensions, the service acquired nine refurbished Strikemasters formerly flown in Kenya and Kuwait.
[20] The Ecuadorian Air Force deployed the Strikemaster during the brief 1995 Cenepa War, flying ground sorties against Peruvian positions.
[22] Operations by the type were restricted by most military users after the Royal New Zealand Air Force found fatigue cracking in the wings of its aircraft.
