Attacks on this boat and other events
29 Apr 1942
A US Navy Catalina flying boat (VP-84) piloted by Lt (jg) Robert A. Proctor dropped four depth charges after locating U-402 on radar about 20 miles south of Cape Lookout, North Carolina. (Sources: Ragnar J. Ragnarsson)
11 May 1943
Kvtkptn von Forstner had just slipped through the convoy screen of SC 129 and sunk two ships when the escort corvette HMS Gentian located and depth charged the boat. Damage was so severe U-402 was forced to return to base, reaching France on 26 May. (Sources: Blair, vol 2, page 329)
7 Sep 1943
Aircraft attack, aircraft shot down:British Wellington MP509 (RAF Sqdn 172/D, pilot F/O C.J. Payne)
23.03 hrs, Bay of Biscay, outbound: after locating U-402 on radar British Wellington bomber MP791 (RAF Sqdn 172/Q, pilot F/O T. Armstrong) dropped six depth charges in a Leigh Light attack and then circled the boat after making a strafing run. At 23.13 hrs they observed another Wellington (Sqdn 172/D) making a Leigh Light attack and being shot down. Wellington Q-Queen was damaged when the port tyre burst on landing at Chivenor: unknown to the crew the undercarriage had been hit twice by flak. U-402 had hit both attackers and escaped undamaged.

06.18 hrs, Bay of Biscay, outbound: investigating a radar contact, British Wellington bomber HF126 (RAF Sqdn 612/M, pilot F/O J.M. Bezer) flew over the boat and turned for a Leigh Light attack. The nose turret guns jammed and the aircraft received several AA hits just before releasing six depth charges. The Wellington had been hit in the nose, fuselage, tail, port engine and starboard wing, and the crew had to jettison all loose equipment, reaching Portreath on one engine 90 minutes later. U-402 was undamaged. (Sources: Franks/Zimmerman)
