The RELAMPAGO, a member of Spains newest BAM class of warships, is a high performance, modular vessel capable of being adapted to a number of roles . . .Much more about the BAM class here.
Basically, though, what you have is a highly automated 20 knot ship with a small crew with enough weaponry for self defense +,
The ship is armed with a OtoBreda 76/62mm gun, two Mk38 25mm automatic cannons and two 12.7mm machine guns. The OtoBreda 76mm compact can fire 85 rounds a minute, while super rapid can fire 120 rounds a minute.
The BAM has a helicopter deck measuring 24.7m by 13.5m. It supports the operations of AB-212, NH-90 or SH-3D Sea King helicopters. The hangar can accommodate an AB-212 or NH-90 helicopter.
The ship's state-of-the-art command and control system allows the crew to operate the vessel in littoral environments. The BAM can carry six containers accommodating UAVs, firing targets, signal simulators, anti-pollution assets, divers support and workshops.and,
The vessel is equipped with a helicopter platform, rescue equipment and medical facilities and can be deployed in a range of missions including patrols and protection.I am not sure why EUNAVFOR is using the term "specialised" in connection with what seems to be a very versatile addition to the counter-piracy fleet off Somalia.
The ship design can also be modified for non-oceanic missions such as hydrographic research, intelligence gathering, divers support and submarine rescue operations.
