The Panavia Tornado is a family of twin-engine, variable-sweep wing multi-role combat aircraft, jointly developed and manufactured by Italy, the United Kingdom, and Germany. There are three primary Tornado variants: the Tornado IDS (interdictor/strike) fighter-bomber, the Tornado ECR (electronic combat/reconnaissance) SEAD aircraft, and the Tornado ADV (air defence variant) interceptor aircraft. The Tornado was developed and built by Panavia Aircraft GmbH, a tri-national consortium consisting of British Aerospace (previously British Aircraft Corporation), MBB of West Germany, and Aeritalia of Italy.
