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 with only one shaft with a larger 5-bladed propeller for improved underwater performance and reduced noise. Draken, Vargen, Nordkaparen and Springaren were ordered from Kockums. Gripen and Delfinen were from Karlskrona. These boats were decommissioned 1988-90 and were succeeded by the Sjöormen-class and Näcken-class submarines.
