Serviola Class Patrol Boat

Serviola Class Patrol Boat

The Serviola-class patrol boats were a series of patrol boats built in 1990 at the shipyard in Ferrol in the former Empresa Nacional Bazan (now NAVANTIA) for the Spanish Navy. They entered service with the Spanish Navy from October 1992. They are based in the Galician port of Ferrol making most of their patrols along the Galician and Cantabrian coasts.

They are designed to remain at sea for long periods of time and withstand rough sea conditions without significant degradation of their capabilities. Each ship is equipped with a flight deck that allows it to operate medium-sized helicopters, a sick bay with six beds, and two rigid inflatable boats.

There are currently four ships in service.


The Serviola-class patrol boats are a modernized version of the Halcón class of the National Bazán Company itself, of which five units were sold to the Argentine Naval Prefecture, built by Bazán-Ferrol, and six others. to the Mexican Navy. These, manufactured in this case by Bazán-San Fernando, and named by their buyer class Uribe, were followed by a series of four from a locally developed and built version designated the Holzinger class and another series of four from a further development known as the Sierra class. .

The design requirements of the Spanish Navy were that they could operate on the high seas for long periods and in heavy seas, without this entailing a loss of their operational capabilities.

They have a flight deck with capacity for medium helicopters, although without a hangar to carry out maintenance; as well as a small hospital for six seats and two semi-rigid boats (or RHIB, short for rigid-hulled inflatable boat, ‘rigid hulled inflatable boat’).

As had happened previously with those of the Anaga class, to save costs they were used to arm the old 76.2 mm Mk.22 cannons disassembled from ships of American origin decommissioned by the Navy, whose military value is very low, instead of opting for the far superior Oto Melara of the same caliber that Bazan itself manufactured under license. In addition, like those, they also do not have an advanced firing direction, resulting in their almost testimonial firepower.
