The Saab JAS 39 Gripen E , the newest and most capable (and only) multirole fighter jet in the Brazilian Air Force, made its debut at a set of war games hosted by Brazil. The Gripen E is the latest variant of the Gripen family of fighter jets that Sweden is looking for international buyers. The Gripen was built by Sweden with an eye for flexibility, ruggedness, ease of maintenance, and the ability to operate in comparatively austere conditions.
