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 submarine 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 (HMS Nordkaparen) was preserved and can today been seen at the Göteborgs Maritima Center in Gothenburg.
