[edit] 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.

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.
