Unterseeboot 489

Unterseeboot 489 (U-489) was a Type XIV U-boat ("Milchkuh") of the Kriegsmarine. Her keel was laid down January 28, 1942, by Germaniawerft of Kiel. She was commissioned March 8, 1943, with Leutnant zur See Adalbert Schmandt in command. Schmandt remained in command for the boat's entire career.

U-489 was lost on her first patrol. As a supply boat, she avoided combat. On August 4, 1943, the boat was attacked by a Canadian Sunderland and a Catalina aircraft southeast of Iceland. One crewman was killed in the attack. The Catalina was damaged, the Sunderland was shot down, and U-489 was sunk. 53 of her crew survived.
