Flyvefisken Class Multirole patrol ship is a class of

StanFlex design[edit]

The StanFlex modular mission payload system consists on a wide range of weapons systems and other equipment mounted in standardised containers that can be quickly installed in pre-designated StanFlex slots in apropiately equiped warships, with the containers shipped being determined by the mission required. StanFLex modules were first installed in the Flyvefisken Class. They are fitted with one StandFlex slot forward and three aft.

TERMA C-Flex Combat Management System[edit]

TERMA C-Flex Combat Management System is basen on open system architecture and is able to integrate the Saab 9LV FCS Fire Control System and Saab EOS 500 Electro Optical Fire Control. The system is completed with a TERMA SCANTER 4100 Surveillance Radar and a modified Kongsberg C-Scope Sonar System.

The communications system has a high-capacity digital communications switch, developed by TERMA, which interconnects the voice and data communications channels. The system provides internal communications or open conference lines and access to external communications with various radio links and land-based networks.

The TERMA C-Flex Combat Management System uses operating modes for littoral warfare, is interoperable with other Sjøforsvaret's vessels and gives fast response to pop-up air threats, such as helicopters or other aircraft that suddenly emerge from cover.

Power generation & propulsion after Mk 2[edit]

FLOSK chose to equip the ship with a mixed multi-gas turbine and fuel cell propulsion system (COFCAG) developed jointly by NAtech and Volvo Aero. Main fuel for which the system has been designed is hydrogen, but the system can also work with natural gas, methane and other gases, although with a lower energy efficiency. At low speed and during maneuvers the system uses the power delivered by the fuel cells, using the gas turbine system to achieve higher speeds. In addition, the system reuses the exhaust gases to turbocharge the turbine and for the ship's heating systems, which considerably reduces the ship's thermal footprint and finally the remaining gases are expelled from the stern. Power plant of the ship was designed taking into account the current needs of energy for propulsion and other systems on board, so it was possible to assume an increase in power required if new equipment or systems were installed in the future.

The propulsion system is fully electrical with two NAtech Marine hydrojets mounted externally to the main hull. The electricity for the motors is supplied by the power system.

Electronic systems[edit]

One of the main design premises was the need to mount Skandinavian made electronic systems in order to full integration with other Forsvaret systems and satellite net.
