Norwegian munitions manufacturer Nammo unveiled its Nammo Modular Strike System (NMSS) at the Eurosatory 2026 exhibition held in Paris from 15-19 June.

The NMSS consists of an MRM2-10 unmanned aerial vehicle (UAV) by Croatian manufacturer Orca. The UAV is designed to drop a Nammo N7 66 mm high-explosive anti-tank (HEAT) munition with a copper conical liner onto armoured targets. The N7 weighs 1.5 kg and can penetrate up to 450 mm of rolled homogeneous armour (RHA), Thorstein Korsvold, director of communications at Nammo, told Janes.

While not showing the NMSS in action, Nammo representatives played a video for Janes to demonstrate a typical use case for the system. The video appeared to show an operator's view of a UAV dropping a warhead onto a Russian multiple rocket launcher (MRL). “The hollow charge ended up in the rocket hub on the back [of the MRL] and ignited the propellant. This resulted in a rocket going straight through the driver's cabin and setting the truck on fire and exploding,” Sigurd Harsheim, project management sales and marketing at Nammo, told Janes. The video was filmed in Ukraine in early 2025, according to Harsheim. The N7 would normally be dropped onto heavier targets than lightly armoured MRL vehicles.

The N7 munition has been sold to Ukraine in six-figure quantities, according to Korsvold. Some units of the Armed Forces of Ukraine (AFU) have been arming various UAVs with the warhead for “some time now”, Harsheim said.
