My interpretation of this thing. Called it the RAPP-class, after "Rap", the first Norwegian fast torpedo boat. Following naval tradition, I allocated the pennant number P 981, which was last held by the SNØGG-class fast attack craft HNoMS RAPP.
Armament and general information is as you can see located within the file. Basically the armament and sensors of a SKJOLD-class in a slightly bigger, slightly slower package.
