The Álvaro de Bazán class are new air defense frigates entering service with the Spanish Navy, equipped with the American-made Aegis combat system. They are being built in Spain and are named after Admiral Álvaro de Bazán. The Aegis system allows the frigates to track hundreds of air targets simultaneously as part of an air defense network. The frigates carry the AN/SPY-1 radar, one of the few non-US warships to use the Aegis system.
