Submarine U3

At Malmö Museer you have the possibility of coming on-board a real submarine, U3.

We are renewing and improving!

January 14–September 2019 The Science and Maritime House, including the submarine U3, is closed.

Slottsholmen including the Aquarium, the Castle and the Restaurant are open as usual. Welcome!

Sense the feeling of being living very densely to other crew members. Imagine what it would be like to find your self hanging between the water surface and the bottom of the ocean. The only thing you can not experience is the smell on board after being several weeks under water.

Where do you sleep? Is the toilet working 100 meters under the sea level? How do you cook on board? Welcome on-board and get some answers!

The Coastal Submarines (U1 - U9) 1941-1944

During the middle of the Second World War nine smaller submarines were built. This type of submarine was the first with a fully Swedish design. By reducing the size, more submarines could be built at the same cost. Responsible was Navy Engineer Swenzén. It is also the first completely welded pressure hull, a construction method developed at the Kockum Shipyard in Malmö (Kockums Mekaniska Verkstad AB).

These small costal submarines were constructed and launched during the years of 1941-1944, five at Kockums and four at the Naval Shipyard in Karlskrona. U3 was built at the Naval Shipyard in Karlskrona.

In the earlier submarines the propulsion was diesel engines at the surface and electrical engines when submerged. This caused a stop in propulsion when switching over from one system to the other and delayed the dive. With the new diesel electrical system the only thing you had to do was to stop the diesel engine. The dive time was reduced to less than 30 seconds.

After the Second World War all Swedish submarines of this type were modified (1952-1953) and equipped with a snorting system. This allowed the diesel engine to run when being at periscope depth and it became possible to recharge the battery without surfacing. The conning tower was modified to carry the snorting system and one of the periscopes was removed. Also the external stern tube and the anti-aircraft gun were removed.

Operation "Museum Submarine" began in 1965 when U3 was towed from Gothenburg to Kockums Shipyard in Malmö. The submarine was cut in three pieces and lifted to the position it has now. The openings fore and aft for visitors were made and the submarine was restored as much as possible.

U3 veteran crew

U3 veteran crew is mainly consisting of retired submarine crew members. Together they have a lot of experience of the work on-board submarines. They help Malmö Museer with maintenance and technical knowledge. The crew is also responsible for the guided tours on-board U3.

Most of the crew members are members of the support club "Stödföreningen för Malmö Sjöfartsmuseum". If you are interested in becoming a member of the support club, please contact Malmö Museer for further information, e-mail:
