The Principe de Asturias (R11) is an aircraft carrier, and the flagship of the Spanish Navy. Principe de Asturias is currently the flagship of the Spanish fleet.
The design is basically that of the initial US Navy Sea Control Ship design of the 1970s, modified to enable V/STOL aircraft to be carried. Constructed by the National Company Bazan (then Empresa Nacional Bazan, now Navantia) in their shipyard at Ferrol. The keel was laid on 8 October 1979. She was launched on 22 May 1982. The ship made her first sea trials in November 1987. Principe de Asturias was delivered to the Navy on 30 May 1988.
The ship is permanently assigned to the Alpha Group, comprising the carrier and six Santa Maria-class frigates (a Spanish version of the USN Oliver Hazard Perry FFGs). Other vessels such as logistic ships, tankers and corvettes are frequently assigned to the Group when required. Principe de Asturias and the Alpha Group have participated in peace support operations in the Adriatic Sea.
