The wreck of the German submarine U-670, sunk on August 20, 1943, has been scanned in detail and documented in the form of a 3D model. U-670 was first identified by divers from the Baltictech team 10 years ago. The latest research, conducted by Daniel Pastwa, has resulted in the creation of a unique and extremely accurate 3D model of the wreck.

The Type VII C submarine belonged to the Kriegsmarine and served in combat for only a few months – from January to August 1943 – before it sank as a result of a collision with the target ship Bolkoburg during a training voyage in the Baltic Sea.

At the time of the disaster, there were 43 crew members on board. Twenty-two of them survived, while 21 died, and their final resting place is now at a depth of 82 meters in the northern part of Jastarnia, off the coast of the Hel Peninsula.

During the exploration, fishing nets were removed, revealing a kiosk, periscopes, an RDF antenna, and a UZO targeting device. The stern of the vessel is destroyed, which remains a physical trace of the collision that led to its sinking.

The documentation process itself required exceptional precision. Nearly 10,000 photographs were taken during the dive, and the total time spent underwater exceeded 3 hours.

Thanks to this research, it has become possible not only to document the condition of the U-boat, but also to better understand the history of the Kriegsmarine’s training voyages in the Baltic Sea during World War II. From a scientific perspective, the project combines underwater archaeology, 3D photogrammetry techniques, and the protection of the cultural heritage of the Baltic Sea.
