Plejad-class torpedo boat

The Plejad class was a series of large torpedo boats operated by the Swedish Navy during the Cold War. They were developed in the early 1950s as part of a new doctrine that emphasized a small coastal fleet compared to capital ships. The vessels were designed in Germany and built in Sweden and were large for their type. The design was well armed, incorporating five guns of various caliber and six torpedo tubes. Aside from the initial prototype Perseus, 11 vessels were built to the design. The last ship entered service in 1958 and was decommissioned in 1981.
