class patrol boats. In December 2008 the NSM was selected by the Polish Navy in which it is now included. The final milestone was completed in June 2011 with tests at pt Mugu. On September 21 a new demonstration video of the missile became famous on youtube hitting over 140.000 views in the first 5 days. This new demonstration shows the missile mission tests for the new F35 Lightning II program. This will be a multi-role version, named the Joint Strike Missile (JSM), and will be the only cruise missile to fit the internal bays of the F-35.

Joint Strike Missile

A multi-role version of the NSM is in development. This missile is called Joint Strike Missile (JSM) and will feature an option for ground strike and a two-way communications line, so that the missile can communicate with the central control room or other missiles in the air. This missile will be integrated with the Lockheed Martin

 "Joint Strike Fighter". Studies have shown that the F-35 would be able to carry two of these in its internal bays, while additional missiles could be carried externally.

According to Kongsberg, this "multi-role NSM" is the only powered anti-ship missile that will fit inside the F-35's internal bays. Lockheed Martin and Kongsberg have signed a joint-marketing agreement for this air-launched version of the NSM, as well as an agreement committing both parties to integrating the JSM on the F-35 platform. The project is funded by Norway and Australia
