Operational career

U-489Template:'s only patrol began with her departure from Kiel on 22 July 1943. She headed for the Atlantic by way of the so-called Faeroes Gap between Iceland and the Faroe Islands, north of the British Isles.

She was attacked by a PBY Catalina flying boat of No. 190 Squadron RAF on 3 August. During the action, the 'Cat' was hit twice and retired. Her crew were obliged to jettison depth charges and on their return, found the rudder cables almost severed. Her place was taken by a Lockheed Hudson of 269 Squadron, which succeeded in damaging U-489.

Although as a supply boat, she avoided combat, she was lost on her first patrol when on 4 August, she was attacked by a Canadian Sunderland flying boat of No. 423 Squadron RCAF, south-east of Iceland. The Sunderland was shot down, five of the eleven man crew were killed; U-489 was sunk. 53 of her crew escaped. All the survivors were picked up by the destroyers Template:HMS and Template:HMS; they had both observed the attack.<ref name="uboatnet"/>
