The BAC 167 Strikemaster was a British Armstrong Siddeley jet-powered training and light attack aircraft. It was a development of the Hunting Jet Provost trainer aircraft, itself a jet engined version of the Percival Provost, which originally flew in 1950 with a radial piston engine.
The BAC 167 Strikemaster is essentially an armed version of the Jet Provost T Mk 5. Aircraft sound recordings of both of these types can be found here.
