Following the war, the Paris Peace Treaty of 1947 prohibited the Finnish Navy from employing torpedo-carrying vessels of any kind and the Taisto class were converted into motor gunboats.

The Finnish Navy, tasked with closing the Gulf of Finland, sought more vessels.

[1] Based on an Italian design and built under license, eight Taisto vessels were manufactured at Turun Veneveistämö.

They were powered by two Isotta Fraschini petrol engines creating 1,700 kilowatts (2,300 bhp) and had a maximum speed of 48 knots (89 km/h; 55 mph).

Westerlund & Chumbley state that by 1964 all eight vessels had been stricken from the Finnish Navy.
