In 4 patrols she sank 3 merchant ships, for a total of 18,609 gross register tons (GRT) and damaged one merchant ship.

Convoy ONS 154[edit]

On the night on 26 December 1942 U-662 reported sighting Convoy ONS 154.

U-662 sunk the crippled and straggling Ville de Rouen which had been attacked earlier by U-225.

July 1943[edit]

On 19 July a US Liberator bomber dropped four depth charges, but broke off the attack after sustaining flak damage. U-662 escaped undamaged.
The next day, U-662 was again attacked by US aircraft, this time a Douglas B-18 Bolo aircraft, but again she escaped undamaged. She was sunk the following day.

Fate[edit]

U-662 was sunk on 21 July 1943 in the North Atlantic in position 03°56′N 48°46′W / 3.933°N 48.767°W / 3.933; -48.767, by depth charges from US Catalina from VP-94 Squadron. Apart from the commander and two other crew members, all hands were lost.
Oberleutnant zur See Heinz-Eberhard Müller was so severely injured that he was repatriated to Germany in March 1944 as he was no longer fit for combat.
