U-110 was a German IXB type submarine, which in May 1941 was captured south of Iceland, intact by a British fleet after being forced to the surface and a British Destroyer (HMS Broadway) made to ram the submarine. Fearing for the crew, and believing the submarine would be sunk, the submarine's commander ordered everyone to abandon the submarine, leaving everything behind. However, the commanding British destroyer ordered the destroyer to abort the ram. The survivors were picked up and a boarding party entered the submarine and removed code books, signal books and charts. The code and signal books proved invaluable in decoding the enigma codes used by the German navy during the Second World War. Fritz Lemp (the commander of U-110) was never seen again. Suggestions that he was shot by the boarding party are rebuked by the leader of the boarding party who suggests that the German commander, ashamed at his error of judgement in allowing his vessel to be captured intact, committed suicide in the water. The submarine was allowed
to sink the next day so that the German's would not know of the capture, and the loss of essential code and signal books.

U-Boats were German armed submarines used during the Great War and Second World War primarily to attack unarmed naval targets, such as merchant shipping. U-boats were of three types: coastal types; sea-going types and ocean-going types, differing primarily in size. The German U-boats of the Second World War were all single-hulled, unlike the earlier submarines used during the Great War which had a double-hull, and with a single-hull were more susceptible to damage from depth-charge attacks.

The Uppland is a Swedish Gotland Class (Type A19) submarine of 1240 tons displacement, commissioned in 1997. The Uppland is manned by a complement of 28 crew and 5 officers The submarines are fitted with four 21 inch torpedo tubes taking the Bofors Torpedo 2000, and two 15.75 inch torpedo tubes taking the Bofors Underwater Systems Type 613 torpedo. The Uppland can also be used to deploy the Bofors Underwater Systems stand-off self-deployed Mine 42. The submarine also has the capacity to carry 48 mines mounted externally in a girdle arrangement. The ship's combat management system is the 9SCS Mark 3 from CelsiusTech. The system carries the Swedish Royal Navy designation SESUB 940A. The system uses an extended version of the ADA software from CelsiusTech's 9LV Mk 3 surface ship combat management system. The fire control system has the capacity to control several torpedoes in the water simultaneously. The new application software includes target motion analysis developed by Kockums and the University of Lund at Malmo. Kockums
have also been responsible for the development of enhanced software for navigation, for torpedo tube control and torpedo tube simulation. The 9SCS Mark 3 Combat Management System has three multifunction consoles, Type IID from Terma. The terminals are for command and control, communications, and weapon control. The consoles are connected via a dual Ethernet copper wire local area network. The combat management system receives data from the submarines' sensors. The submarine is equipped with a CSU 90-2 integrated sonar sensor suite from STN Atlas Elektronik. This includes a passive cylindrical bow array, an intercept array and two passive flank arrays. The sonar system uses ADA software. The submarine is equipped with a Kollmorgen search and attack periscope and a Terma Scanter navigation radar. The electronic support measures system is the Racal Thorn Manta radar surveillance and warning system as deployed on the British Royal Navy Oberon and Churchill class submarines. Manta carries out surveillance, detection,
analysis, classification and identification of hostile radar threats from D-band to J-band. The Manta system also provides a prediction of the detectability of the host submarine by the threat radar using a combination of data from the hostile radar frequency, the sea state and the configuration of the submarine's periscope assembly. The submarine is equipped with two MTU diesel engines and two Kockums V4-275R Stirling Air Independent Propulsion units. The Stirling engines are mounted in elastic, soundproof modules and each provide up to 75 kW. The submarine has the capacity for two weeks of air independent propulsion at a speed of 5 knots without snorting. The AIP uses liquid oxygen and diesel fuel in a controlled inert (helium) environment. The AIP liquid oxygen tanks are located on the deck below the engines. The propulsion system provides a speed of 11 knots surfaced and 20 knots dived.
