With U-889 out of the water, the submarine's propellers, rudders, diving planes, and rearward-firing torpedo tubes are clearly visible.
The two propellers (centre bottom), each with three paddle-shaped blades, received power from U-889's diesel engines or its electric motors, and drove the submarine through the water. The rudders (twin vertical blades) and diving planes (twin horizontal blades) helped steer and control U-889. Caps covered the two rearward-firing torpedo tubes (centre), opening when a torpedo was to be fired.
