NASAMS is a highly adaptable, networked short- to medium-range ground-based air defense system developed jointly by Norway's Kongsberg Defence & Aerospace and the U.S. company Raytheon (RTX Corporation).​
 
Key Features

• It uses a network-centric architecture for enhanced survivability and integration with other air defense equipment and systems.
• The system's primary radar is a high-resolution 3D X-band phased array radar capable of 360-degree coverage with a detection range of about 75 kilometers.​
• NASAMS can engage multiple targets simultaneously—up to 72 targets in active and passive modes—and is capable of firing missiles based on data from external sensors.​

• The main interceptor missile used is the AIM-120 AMRAAM (Advanced Medium-Range Air-to-Air Missile)
• NASAMS 3, the latest upgrade, also incorporates AIM-9X Sidewinder missiles for shorter-range engagements.
• Launchers typically carry up to six missiles each.

Its networked design allows it to defend high-value assets, critical infrastructure, and population centers against a range of aerial threats including drones, cruise missiles, helicopters, and fixed-wing aircraft.​
