The operational requirements for today's Eurofighter Typhoon, the world's most advanced swing-role combat aircraft, were agreed by the Chiefs of Air Staff of Germany, Italy, Spain and UK in the form of a European Staff Requirement which was re-affirmed in January 1994. 

The agreement, the basis for the project's development program, defined the requirement for an extremely agile fighter that will dominate the skies to the mid-21st Century - a single seat, twin-engine fighter with optimal performance in Beyond Visual Range (BVR) and close combat, with significant ground attack capabilities.

Eurofighter Typhoon offers maximum operational effectiveness and flexibility, high survivability, extensive technological growth potential, as well as high reliability and maintainability with low operating costs.
