Variants
The Eurofighter is produced in single-seat and twin-seat variants. The twin-seat variant is not used operationally, but only for training. The aircraft has been manufactured in three major standards; seven Development Aircraft (DA), seven production standard Instrumented Production Aircraft (IPA) for further system development and a continuing number of Series Production Aircraft. The production aircraft are now operational with the partner nation's air forces.
The Tranche 1 aircraft were produced from 2000 onwards. Aircraft capabilities are being increased incrementally, with each software upgrade resulting in a different standard, known as blocks. With the introduction of the block 5 standard, the R2 retrofit programme began to bring all aircraft to that standard.
