The Draken class (Dragon) was a submarine class built for the Swedish Navy 1960-1962. A total of six submarines was delivered and kept in service until the late 1980s when the more modern Näcken-class replaced them. 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.

One submarine (HSwMS Nordkaparen) was preserved and can today been seen at the Maritiman in Gothenburg.[1][2]
