Ukraine is set to receive a new weapons system in its conflict with Russia – the Norwegian Advanced Surface-to-Air Missile Systems or NASAMS.Designed to provide medium to long-range air defence against aircraft, cruise missiles or drones, NASAMS can fire short-range AIM-9X Sidewinder missiles plus the medium-range AIM-120 – identical to the missiles used on fighter aircraft.The weapons system is the same one used to defend the White House and Capitol Building in the US.
