The Schnorchel
U-boats fitted out with Schnorchel
On this page I'll attempt to list the boats fitted out with the Schnorchel breathing device. This listing does not include boats that were built with the device from the start such as the Elektro boats of types XXI and XXIII and later model VIIC/41 boats.
U-58 was the first one to be fitted out, she participated in Schnorchel experiments during August of 1943. Over 200 traditional U-boats (non Elektro boats) were fitted out with the equipment before the war ended, probably more.
The first U-boat to leave for combat patrol was the U-539 when she departed France on Jan 2, 1944. Many sources say this boat was the U-264 but she sailed a month later on Feb 2.
Germany had at least 35 Schnorchel- equipped boats before the Normandy invasion took place on June 6, 1944. Still roughly half of the operational boats in France did not have this vital equipment at the time.
