Flyvefisken class patrol vessel

Flyvefisken class patrol vessel

The Flyvefisken class patrol vessels are warships of the Royal Danish Navy. The class is also known as the Standardflex 300 or SF300 class.

Containerised weapon systems

The Flyvefisken ships are innovative in that they were built with a modular design: they have a standard hull in which containerised weapon systems can be placed. This allows them to change roles. Typically 48 hours are necessary to change roles. This enables the ships to be configured to perform these roles:

  • surveillance
  • surface combat
  • anti-submarine warfare (ASW)
  • mine countermeasures/minehunter
  • minelayer
  • pollution control

The containers measure 3.5x3x2.5 m. One container goes on the foredeck; the other 3 go on the quarterdeck behind the superstructure and funnel.

Ships in class

A total of 14 ships, where build in the class in three series:

Series 1 = P550-P556, series 2 = P557-P562, series 3 = P563.
The difference between the series is mainly in the configuration of the propulsion system. Series 2 is not equipped with hydraulic propulsion, but instead has one more aux. engine, and series 3 has further one aux. engine.
