The Panavia Tornado Air Defence Variant (ADV) is a long-range, twin-engine swing-wing interceptor aircraft developed by the European Panavia Aircraft GmbH consortium. It was a specialised derivative of the multirole Panavia Tornado and it was equipped with a powerful radar and beyond-visual-range missiles. Having been based on the multinational Tornado IDS, development was relatively quick. It was operated by the Royal Air Force (RAF), Italian Air Force (AMI) and the Royal Saudi Air Force (RSAF).
