The Álvaro de Bazán class, also known as the F100 class, is a class of Aegis combat system-equipped air defence frigates in service with the Spanish Navy. The vessels were built by Spanish shipbuilder Navantia in Ferrol, with the lead ship of the class named for Admiral Álvaro de Bazán.

The F110 class, also known as the Bonifaz class, are a multi-purpose, anti-submarine class of Aegis combat system-fitted heavy frigates under construction for the Spanish Navy. The project is being co-developed by the Spanish Ministry of Defence and the state-owned company Navantia. The construction of the first unit started in April 2022. Deliveries are scheduled to start in about 2025.
