The Handley Page Victor is a British jet-powered strategic bomber, developed and produced by Handley Page, which served during the Cold War. It was the third and final V bomber to be operated by the Royal Air Force (RAF), the other two being the Avro Vulcan and the Vickers Valiant. The Victor had been developed as part of the United Kingdom's airborne nuclear deterrent. In 1968, it was retired from the nuclear mission following the discovery of fatigue cracks, which had been exacerbated by the RAF's adoption of a low-altitude flight profile to avoid interception.
