German submarine U-153 was a Type IXC U-boat of Nazi Germany's Kriegsmarine built for service during World War II. The keel for this boat was laid down on 12 September 1940 at the DeSchiMAG AG Weser yard in Bremen, Germany as yard number 995. She was launched on 5 April 1941 and commissioned on 19 July under the command of Korvettenkapitän Wilfried Reichmann.
The submarine began her service life with training as part of the 4th U-boat Flotilla; moving on to the 2nd flotilla for operations. She conducted two patrols, sinking three ships.
She was sunk by an American destroyer in July 1942.

## Design

German Type IXC submarines were slightly larger than the original Type IXBs. U-153 had a displacement of 1,120 tonnes (1,100 long tons) when at the surface and 1,232 tonnes (1,213 long tons) while submerged. The U-boat had a total length of 76.76 m (251 ft 10 in), a pressure hull length of 58.75 m (192 ft 9 in), a beam of 6.76 m (22 ft 2 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.70 m (15 ft 5 in). The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines producing a total of 4,400 metric horsepower (3,240 kW; 4,340 shp) for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of 1,000 metric horsepower (740 kW; 990 shp) for use while submerged. She had two shafts and two 1.92 m (6 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).
The submarine had a maximum surface speed of 18.3 knots (33.9 km/h; 21.1 mph) and a maximum submerged speed of 7.3 knots (13.5 km/h; 8.4 mph). When submerged, the boat could operate for 63 nautical miles (117 km; 72 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 13,450 nautical miles (24,910 km; 15,480 mi) at 10 knots (19 km/h; 12 mph). U-153 was fitted with six 53.3 cm (21 in) torpedo tubes (four fitted at the bow and two at the stern), 22 torpedoes, one 10.5 cm (4.13 in) SK C/32 naval gun, 180 rounds, and a 3.7 cm (1.5 in) SK C/30 as well as a 2 cm (0.79 in) C/30 anti-aircraft gun. The boat had a complement of forty-eight.

## Service history

On 15 November 1941, U-153 collided with the German Type VIIC submarine U-583 in the Baltic Sea off Danzig (55°23′N 17°05′E﻿ / ﻿55.383°N 17.083°E﻿ / 55.383; 17.083). U-153 remained afloat, but U-583 sank with the loss of 45 crew members.

### First patrol

U-153′s first patrol began with her departure from Kiel on 18 May 1942. After a brief stop in Kristiansand in Norway, she headed for the Atlantic Ocean via the gap between the Faroe and Shetland Islands. After a long southwest, south and southeast sweep, she docked at Lorient in occupied France, on the 30th.

### Second patrol and loss

She sank Anglo-Canadian on 25 June 1942 800 nmi (1,500 km; 920 mi) northeast of Antigua. The survivors were helped to lifeboats and received water and cigarettes. The following day, she sank Potlatch, about 650 nmi (1,200 km; 750 mi) east of the Virgin Islands. She also sank Ruth on the 29th about 320 nmi (590 km; 370 mi) north northeast of Barbuda.
U-153 was attacked by US A-20A Havoc aircraft of the United States Army Air Forces 59th Bombardment Squadron (Light) on 6 July 1942 in the eastern Caribbean. She was sunk on 13 July 1942 near Colón, Panama, not far from the entrance to the Panama Canal, by the United States Navy destroyer USS Lansdowne (DD-486).
