German submarine U-862 was a Type IXD2 U-boat of Nazi Germany's Kriegsmarine during World War II.

The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines plus two MWM RS34.5S six-cylinder four-stroke diesel engines for cruising, producing a total of 9,000 metric horsepower (6,620 kW; 8,880 shp) for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of 1,000 shaft horsepower (1,010 PS; 750 kW) for use while submerged.

Penang was the base for the 33rd U-boat Flotilla, code-named Monsun Gruppe ("Monsoon Group").

[5] This has given birth to an urban legend in New Zealand, where it is said that the captain of U-862 sent sailors ashore at night to steal fresh milk from a farm.

This may arise from a joke made by Captain Timm to Air Vice Marshal Sir Rochford Hughes in the late 1950s.

[6] U862's voyage to New Zealand was portrayed in a stage comedy U Boat Down Under which was written and directed by Peter Tait and performed at Downstage Theatre, Wellington from 27 July to 5 August 2006.

On 6 February 1945, about 1,520 km (820 nm) south-west of Fremantle, U-862 sank the U.S.-registered Liberty ship, Peter Silvester, which was loaded with mules bound for Burma.

The radar had a range up to 7 nmi (13 km; 8.1 mi) and was very effective where there was little risk from air attack on the U-boat.
