were slightly larger than the original Type IXCs. U-168 had a displacement of when at the surface and while submerged. The U-boat had a total length of, a pressure hull length of, a beam of, a height of, and a draught of. The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines producing a total of for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of for use while submerged. She had two shafts and two propellers. The boat was capable of operating at depths of up to. The submarine had a maximum surface speed of and a maximum submerged speed of. When submerged, the boat could operate for at ; when surfaced, she could travel at. U-168 was fitted with six torpedo tubes, 22 torpedoes, one SK C/32 naval gun, 180 rounds, and a SK C/30 as well as a C/30 anti-aircraft gun. The boat had a complement of forty-eight.
Service history
U-168 conducted four patrols, sinking three ships totalling and damaging one other grossing.
1st patrol
U-168s first patrol commenced with her departure from Kiel on 3 March 1943. Her route took her through the Kattegat and Skaggerak, along the coast of Norway, through the 'gap' between Iceland and the Faroe Islands and into the Atlantic Ocean south and southwest of Greenland. She arrived at Lorient in occupied France on 18 May.
The submarine began her third and what would turn out to be her most successful patrol when she departed Penang on 7 February 1944. She fired three torpedoes at the British salvage vessel south of Ceylon on the 14th. One of the projectiles malfunctioned, but the other two were sufficiently destructive to send the ship to the bottom. The following day she sank a Greek ship, Epaminondas C. Embiricos about north of Addu Atoll in the Maldives. The Master and the Chief Engineer were both taken prisoner and handed over to the Japanese. The former's captivity prevented disciplinary action being taken over why he had ordered the undamaged ship to be abandoned and why the vessel was stationary for two hours, despite standing orders to the contrary. U-168 also damaged the Norwegian Fenris with her last torpedo on the 21st west of the Maldives, but had no ammunition left for her deck gun to finish the ship off which continued to Bombay under her own power. The boat returned to Batavia on 24 March.
4th patrol and loss
The submarine left Batavia on 5 October 1944. According to normal procedures to safeguard friendly submarines the U-168 gave local Japanese units its precise departure and arrival times, intended course and speed. This was subsequently decrypted and included in a FRUMEL report on the 5th of October, 1944. With little time, the Free Dutch Forces submarine, under the command of Lieutenant Commander H Goosens, was ordered to intercept. Shortly after sunrise on 6 October, while in the Java Sea, U-168 was spotted on steady easterly course and fired upon by a spread of six torpedoes. The torpedoes were spotted mere seconds before impact, being struck by two. One hit the U-168s pressure hull but failed to detonate. The second hit the forward torpedo room and exploded. Attempts to stem the flooding failed and the U-168 sank rapidly. The attack killed 23 men, with a further 27 being captured including Pich. In his interrogation, unaware of Allied code-breaking and signals intelligence, Pich could not explain why he'd been caught unawares with one of his crewmen blaming the Japanese, complaining that they never started anti-submarine air searches before 11:00. In late-2013 divers found what is believed the wreck of the boat though it is pointed out that alternatively it could be the wreck of.
