The Panavia Tornado is a family of twin-engine combat aircraft, which was jointly developed by the United Kingdom, West Germany and Italy. There are three primary versions of the Tornado; the Tornado IDS (Interdictor/Strike) fighter-bomber, the suppression of enemy air defences Tornado ECR (Electronic Combat/Reconnaissance) and the Tornado ADV (Air Defence Variant) interceptor. It is one of the world's most sophisticated and capable interdiction and attack aircraft, with a large payload, long range and high survivability. The aircraft has been labelled as "for more than a quarter of a century... the most important military aircraft in Western Europe."
