Flugsicherungsschiff Boelcke was built at the end of 1942 in the Hamburg shipyard Norderwerft Koser & Meyer. The unit stationed in the Baltic region, dealt with the provision of supplies for seaplanes and flying boats of Luftwaffe and conducting minor repairs.

Boelcke was sunk just before the end of World War II, April 17, 1945, during an allied air raid. As a result of the explosion there were killed 20 crew members.

Confirmation of the identity of the wreck took place thanks to the characteristic elements of the unit. They can be seen on archival photos and film frames recorded during the dive. Film registered reliable Slawek Packo while descending to the wreck with Dimitris Stavrakakis.
Boelcke is a wreck 78 m long and over 10m wide. Going down to this position we find the quarterdeck on the depth of about 60m while at the bottom the measuring instruments indicate 75m. During its service it driven by two, 12-cylinder engines from MAN, that put into a motion two three bladed propellers with a diameter of 185cm. This all allowed it to develop a speed of 21.5 knots.
At the same time on the board, in the workshop it was possible to host up to 3 aircrafts, which ensured an escort of 5 antiaircraft guns (2 × 2.0 cm and 3x 3,7cm) and 2 heavy machine guns.
