Sunk at 1550hrs on 12 July, 1943 in the North Atlantic west of Vigo, Spain, in position 42.30N, 16.30W, by 7 depth charges from an US B-24 Liberator aircraft (USAF-A/S Squad. 1). 48 dead and 6 survivors.
The boat was located by SC137 10cm radar which the Germans could not detect. About 15 men were seen in the water after the boat broke in two. The attacking pilot dropped a liferaft and a smoke flare to assist the survivors. 6 men were picked up from the sea by a British destroyer on 15 July, 3 days after the sinking.
U-506 (along with U-156 and U-507 and Italian submarine Cappellini) took part in the rescue operations after the sinking of SS Laconia in September 1942 off Africa. About 1500 men were saved by these boats and French ships from Dakar (which arrived on Sept 16, 4 days after the sinking).

An American B-24 Liberator bomber, piloted by James D. Harden, attacked the boat - carrying 151 survivors from the Laconia, 142 of those on the deck - but the boat dived and survived unharmed. Harden had attacked the U-156 the day before. These attack resulted in the Laconia Order by Dönitz. (Sources: Blair, vol 2, page 64.)
