On 23 December 2011, the Spanish Ministry of Defence awarded a €2 million contract to Indra and Navantia for the design of an integrated sensor mast.

[12] In 2015, both companies agreed to develop and integrate the mast and future sensor suite in the ship's SCOMBA (Local Aegis version) combat system.

[14] In September 2018, the Spanish Ministry of Defence announced the selection of the Raytheon RIM-162 ESSM Block 2 as the ships' primary anti-air self-defence weapon.

[17] According to statements by Frigate Captain Carlos Martínez-Merello, Head of the Resources and Media Definition Section of the General Staff of the Navy in 2010, during the Conference on Naval Programs in progress and future programs, that the new frigate must be adapted to the current scenarios in response to conventional and asymmetric threats, such as patrol of a coastline or operations against pirates, which do not require a large vessel.

The F110 will have a multi-purpose area for flexible mission profiles, 240 days of operation at sea, and 18 months of high availability.

[23] To make it more difficult to locate by radar or thermal imaging, the class will have some stealth capacity, with masts or blocks of sensors not installed on the superstructure.
