Sweden is planning to transition from its earlier model Gripens to the more capable E/F models, (Paid Subscription Required) with improved payload and range capabilities.
The idea is that SAAB will find it easier to sell the aircraft abroad if the line is already for the Swedish military.
I still think that this aircraft is a winner simply because it so much cheaper to own and operate than its competition.
By mid next year, they should be testing the AESA radar, improved avionics, and the ability to carry larger external tanks.
