German submarine U-825 was a special kind of submarine called a Type VIIC U-boat. It was built for Nazi Germany's navy, the Kriegsmarine, during World War II.

The U-825 was started on 19 July 1943 by a company called Schichau-Werke in Danzig. It was officially launched into the water on 16 February 1944. The submarine was ready for duty on 4 May 1944, led by a commander named Gerhard Stoelker.

About the U-825 Submarine

How it was Designed

The U-825 was a Type VIIC submarine. These were a common type of German U-boat. It was designed to be strong and effective underwater.

When it was on the surface, the U-825 weighed about 769 tonnes. Underwater, it weighed more, around 871 tonnes. The submarine was about 67.10 meters (220 feet) long. Its widest part, or beam, was about 6.20 meters (20 feet) across.

How it Moved

The U-825 used two large diesel engines when it was on the surface. These engines gave it a top speed of about 17.7 knots (32.8 km/h or 20.4 mph). When it was underwater, it switched to two electric motors. These motors allowed it to travel at about 7.6 knots (14.1 km/h or 8.7 mph).

The submarine could travel a very long way on the surface, about 8,500 nautical miles (15,742 km) at a slower speed. Underwater, it could go about 80 nautical miles (148 km) before needing to surface. It could dive to a depth of about 230 meters (750 feet).

What Weapons it Carried

The U-825 was armed with several weapons. It had five torpedo tubes, which are tubes that launch torpedoes. Four of these were at the front and one was at the back. It could carry 14 torpedoes.

It also had a large 8.8 cm deck gun on its top, which could fire 220 rounds. For defense against airplanes, it had a 3.7 cm anti-aircraft gun and two twin 2 cm anti-aircraft guns. The submarine usually had a crew of 44 to 60 sailors.

U-825 in Action

Its Missions

The U-825's first job was training. From May to November 1944, it was part of the 8th U-boat Flotilla. Then, from December 1944 to May 1945, it joined the 11th U-boat Flotilla for active service.

The submarine went on two patrols during the war:

  • The first patrol was from 29 December 1944 to 18 February 1945.
  • The second patrol was from 1 April to 13 May 1945.

During its time in service, the U-825 damaged one merchant ship and caused another merchant ship to be a total loss.

What Happened to the U-825

The U-825 surrendered on 13 May 1945. This happened at a place called Loch Eriboll in Scotland. After the war, many captured German U-boats were sunk so they couldn't be used again. The U-825 was sunk on 3 January 1946. This was part of an operation called Operation Deadlight.
