Sweden has been an operator since the late 90's and also have the largest fleet of Gripen C/D in operational service. Sweden has also ordered 60 Gripen E and together with Brazil who has ordered 36 Gripen E/F, they will become the first users of the Gripen E series.
Gripen C/D fighters are currently in-service with two NATO-members nations - Czech Republic and Hungary, as well as South Africa and Thailand. Gripen with its inherent growth capability will remain the backbone of these air forces for the next 30 + years.
