Hawker Siddeley Buccaneer S Mark 50 1970. South Africa was the only country other than the UK to operate the Buccaneer, where it was in service with the South African Air Force from 1965 to 1991. In January 1963, even before the H.S. Buccaneer S had entered squadron service, South Africa had purchased 16 Spey-powered Buccaneers. The aircraft order was part of the “Simonstown Agreement”, in which the UK obtained use of the Simonstown naval base in South Africa in exchange for maritime weapons.
