Ukraine: What is the NASAMS air defence system?

The weapons system is the same one used to defend the White House and Capitol Building in the US.

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 latest version uses the GhostEye radar system originally developed for the Patriot air defence system.

The system has a limited range of about 20 miles, meaning it is best suited to defend key infrastructure and population centres.
