The submarine was powered by two Benz six-cylinder diesel engines producing a total 270 metric horsepower (270 shp; 200 kW), two Siemens-Schuckert electric motors producing 280 metric horsepower (210 kW; 280 shp), and one propeller shaft.

[2] In the 1980s a shipwreck was discovered by the Flemish Hydrographic Service some 50 kilometer from the Belgian shore and was put on the map as B140/225.

The bow has been completely destroyed, apparently by a heavy impact, and it appears to have been squashed from above, with the hull split in two lengthwise.

At 20 meters from the bow lie two large iron fragments on the port side, pieces of the pressure hull of the submarine, probably from the 2 forward depth rudders.

The fact that two hatches were closed and that both periscopes were retracted may indicate that the UB-32 was submerged when hit or diving.

The bow with the accommodation for the crew, the torpedo hold and the battery compartments, has been completely disassembled.

Relatively large fragments have also been found at a distance from the wreck, such as the sheet-iron pieces of the front depth rudders.

The force that was developed was so great that it caused the fragments to fling and the two periscope heads to explode.
