Attacks on this boat
9 Oct 1943
The boat was shelled by a coastal battery at Barentsburg (Spitsbergen), but dived before being hit.
6 Mar 1944
Aircraft attack, aircraft shot down: British Liberator Mk.V BZ764 (RAF Sqdn 120/B, pilot F/L Harold F. Kerrigan, RCAF)
The aircraft located U-737 with radar west of the Lofoten Islands, and despite AA hits causing a fire in the starboard outer engine, dropped six depth charges that detonated as close as 10 meters to the U-boat as it dived, forcing it to resurface immediately. The Liberator attacked again, but sustained more flak damage - one round hit the nose, wounding both navigators and disabling the bomb sight and release gear, so that no more depth charges could be dropped. The aircrew managed to put out the fire and jettisoned the remaining depth charges. One of the wounded navigators guided the aircraft to Skitten, Scotland, where the it made a belly landing on two engines and was later written off.The pilot was later awarded the DSO and the navigator the DFC for their actions. The damage forced U-737 to abort to Narvik. (Sources: Franks/Zimmerman)
22 Oct 1944
The boat was attacked in the Arctic Sea by a Soviet aircraft. Three crew members were injured and the boat suffered slight damage.
3 recorded attacks on this boat.
Men lost from U-boats
Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-737 did not suffer any casualties (we know of) until the time of her loss.
