Tapper-class boats' first function is to protect and patrol the Swedish coastal waters.

Their armament includes 12.7 mm heavy machine guns, anti-submarine rockets, naval mines and depth charges.

These patrol boats have a crew of eight sailors - consisting of four officers and four ratings.

From 1993 to 1999 a total of twelve ships were constructed and entered service with the Swedish Navy and amphibious corps.

In 2020 the first six boats of the class had a comprehensive overhaul and upgrade program in which they were equipped - among other things - with the Kongsberg Maritime sonar for anti-submarine warfare.
