The JSF order cost six billion kroner (6.7 billion euros, $8.4 billion) less than its Swedish competitor, the Norwegian government said without giving precise figures on the total value of the deal.
…the government said thattotal costs over the lifetime of the aircraft are estimated at 145 billion Norwegian crowns ($20.43 billion).

Cette différence de 8,4 milliards $ est à chercher, non pas seulement dans le coût d'achat de 48 appareils, mais bien dans ce qu'ils coûteront au total durant leur temps de service.
