Norway's surprise decision last week to support the Lockheed Martin F-35 was based largely on an analysis by the Norwegian Defense Research Establishment. Among other things, its computer simulations found the F-35 superior to the Gripen NG in dogfights against the SU-30.
So I called Oslo this morning to ask for an interview with the director. Alas, he's off this week deep-sea diving in Egypt! The timing of Norway's announcement caught most observers expecting a mid-December update by surprise. Perhaps the vacationing director of Norway's defense research unit was caught off-guard as well?
