The NSM is an anti-ship and land attack missile developed by the Norwegian company Kongsberg Defence & Aerospace (KDA). It uses composite materials to achieve stealth capabilities, and it weighs over 400 kg and ranges over 185 km (100 nautical miles). The NSM can fly over, and around the land, gliding in sea skim mode and then performing random manoeuvres in the terminal phase, making it more difficult to stop enemy countermeasures.

The Álvaro de Bazán class frigates are equipped with the Aegis combat system that is in service with the Spanish Navy.
