The S-Boot was Germany's largest fast attack boat of WWII. Built in numbers and continually improved, these vessels were equipped with powerful engines, enabling speeds exceeding 40 knots. To counter increasing threats, later models featured reinforced protection for the crew. Despite their speed and firepower, the S-Boats suffered heavy losses during the war.

S150, commissioned in 1943, was tragically sunk in 1944 during an air raid on Le Havre.

Post-war, surviving boats were distributed to various countries, including the Soviet Union, Norway, and Denmark. Some were even returned to Germany for experimental purposes.
