Taisto-class motor torpedo boat

The "Taisto" class motor torpedo boats (English: Battle) or T class was a Finnish-designed class of motor torpedo boats, which saw service with the Finnish Navy during World War II.
In 1943, the Finnish Navy was in great need for new motor torpedo boats and the Finnish ship designer Jarl Linblom studied the Finnish Navy's Italian-designed motor torpedo boats and improved the design. The improved hull design gave them better seaworthiness and the boats could reach up to without armament. Six were manufactured at "Turun Veneveistämö" during the war, and called the "Taisto class".
In the summer of 1944 the motor torpedo boats participated in the battles near the Karelian Isthmus. On 21 June the Taistos were attacked by Soviet aircraft, who managed to sink "Tarmo" and damage "Tuuli", resulting in the loss of two men. The T class served with distinction during the attempted conquer of the island of Hogland in Operation Tanne Ost.
Five of the six vessels survived the war, and another two were manufactured after the war. The ships were converted into patrol boats in 1949, in accordance with the Paris peace treaty. The T class vessels served until 1964, when they were auctioned out.
