The Type 37 torpedo boat was a class of nine torpedo boats built for Nazi Germany's Kriegsmarine during World War II. Completed in 1941–1942, one boat helped to escort a commerce raider passing through the English Channel into the Atlantic Ocean in late 1941, but their first major action was in early 1942 when they formed part of the escort for a pair of battleships and a heavy cruiser through the Channel back to Germany in the Channel Dash. Two pairs of boats were sent to France at different times in mid-1942 and were part of the escort during an unsuccessful attempt to pass a different commerce raider back through the Channel in October. One boat was assigned to the Torpedo School as a training ship in mid-1942 and the others followed in the next year.

The 10.5 cm SK C/32 (SK - Schiffskanone C - Construktionsjahr, was a widely used German naval gun on a variety of Kriegsmarine ships during World War II. Originally designed as a surface weapon, it was used in a number of other roles such as anti-aircraft and coastal defence; wet-mounts were developed for U-boats.
