THE Jaguar stands out today as one of the most successful examples of international collaboration in the whole field of aerospace technology. It is only just over three years since Britain and France decided to pool resources and produce a common aircraft type — or rather a closely related family of types — to meet their needs for ground attack, close support, battlefield reconnaissance, advanced flight training (including an introduction to supersonic flight), weapons training (all types of tactical weapon), carrier‐based strike and combat duties generally. In that time not only has the design crystallized but the first aircraft has got into the air and four hundred production aircraft are on firm order.
