Draken II-class submarine

The Draken class (Dragon) was a submarine class built for the Swedish Navy from 1960 to 1962. A total of six submarines were delivered. Four of the boats were modernised in 1981–82. The design was a modified version of the Hajen-class submarine with only one shaft with a larger 5-bladed propeller for improved underwater performance and reduced noise. HSWMS Draken, HSWMS Vargen, HSWMS Nordkaparen and HSWMS Springaren were ordered from Kockums. HSWMS Gripen and HSWMS Delfinen were from Karlskrona. These boats were decommissioned 1988-90 and were succeeded by the Sjöormen-class submarine and Näcken-class submarine submarines.

One submarine, HSwMS Nordkaparen, was preserved and can today been seen at the Maritiman in Gothenburg.
