Attacks on this boat

16 May 1943
At 11.40 hours, the inbound boat was unsuccessfully attacked with four depth charges by a British Whitley aircraft (10 OTU RAF/E) in the Bay of Biscay. (Sources: Franks/Rohwer)

16 May 1943
At 14.55 hours, the inbound boat was attacked by the British Liberator aircraft FL948 (224 Sqdn RAF/M, pilot F/S J.S. Powell) in the Bay of Biscay. The aircraft was hit by AA fire during the first attack, so the six depth charges dropped undershot. While it turned around for a second attack, U-648 crash-dived and the remaining four depth charges were dropped into the wake without damaging the boat. The damaged Liberator returned safely to base. (Sources: Franks/Zimmerman)

17 May 1943
Aircraft attack, aircraft shot down:British Whitley Z9438 (10 OTU RAF/J, pilot Sgt J.H. Casstles)

At 14.24 hours, the inbound boat was attacked by the Whitley in the Bay of Biscay. The aircraft dropped four depth charges before it was shot down by AA fire, but did no damage. The entire crew of six men was lost.

20 Nov 1943
Aircraft attack, aircraft shot down: Canadian Sunderland W6031 (422 Sqdn RCAF/G, pilot F/O J.D.B. Ulrichson, RCAF)

At 17.45 hours, the boat was attacked by the Sunderland near the combined convoy SL-139/MKS-30. U-648 had been warned by the Naxos reciever and fought off an attack with accurate AA fire. About one hour later the aircraft sent a distress call that they were about to ditch in 42°40N/19°30W. However, the 11 crewmen were never found.

(Sources: Franks/Zimmerman)

21 Nov 1943
Aircraft attack, aircraft shot down: British Liberator BZ819 (53 Sqdn RAF/A, pilot W/C H.R.A. Edwards, AFC)

At 04.12 hours, the boat was attacked by the Leigh Light equipped Liberator near convoy SL-139. The aircraft was apparently hit by AA fire during the strafing attack and its depth charges fell wide. During the return flight three engines failed and the Liberator had to ditch but only the pilot survived and was picked up by HMS Lincolnshire on 22 November.
