HSwMS Perseus

HSwMS Perseus (T 101) was an experimental torpedo boat operated by the Swedish Navy during the 1950s and 1960s. She was ordered as part of a new doctrine that emphasized a small coastal fleet compared to capital ships. The design featured four torpedo tubes along with several guns of various caliber and was equipped with diesel engines and a gas turbine that allowed for a top speed of 40 knots (74 km/h; 46 mph). The ship was commissioned in 1951 and used to develop the design into the subsequent Plejad-class torpedo boat (1953). After being rebuilt several times to test further designs, she was decommissioned in 1967.
