"Receiving the first three aircraft in November 2017 was a major milestone for Norway. The program delivers on all key criteria: Time, cost and performance. Through the verification of the production version of the drag chute on our production model of the F-35, the weapons system is expected to fully qualify for arctic conditions this spring," said Maj. Gen. Morten Klever, Program Director for the F-35 program in Norway's Ministry of Defense.

The chute — unique to the Norwegian aircraft — is housed under a small fairing on the upper rear fuselage between the vertical tails. It is being added in order to rapidly decelerate Royal Norwegian Air Force F-35s after landing on the country’s icy runways when there are challenging wind conditions. Other country’s may adopt the system.
The Royal Norwegian Air Force had three aircraft delivered to Norway, Ørland in November 2017. Norway will receive six aircraft annually from 2018-24.
