The RNoAF will conduct several investments in the coming years. First the European helicopter NH-90 will be introduced to replace the Lynx helicopters as a ship-borne helicopter, the Air Force also have bought an additional 16 search and rescue AgustaWestland AW101 helicopters to replace its aging Sea King helicopters. The aging F-16AM fighter will be replaced from 2016. On 20 November 2008, Prime Minister Jens Stoltenberg announced that the F-35A was the only fighter fulfilling all the Norwegian requirements and thus the preferred choice. Stoltenberg stated that cooperation with the Nordic countries on defence and security would continue independently of the F-35 purchase.
