German submarine U-30

German submarine U-30 was a Type VIIA U-boat of Nazi Germany's Kriegsmarine during World War II. Commissioned in 1936 under the command of Kapitänleutnant Fritz-Julius Lemp, it gained immediate notoriety for its involvement in one of the war's first major maritime incidents. The submarine served throughout the conflict, participating in multiple combat patrols across the Atlantic Ocean and the North Sea before being scuttled at the end of hostilities.

Service history

U-30's service began with its commissioning into the Kriegsmarine's 2nd U-boat Flotilla, based in Wilhelmshaven. On 3 September 1939, just hours after the United Kingdom declared war on Nazi Germany, U-30 torpedoed and sank the British passenger liner SS *Athenia* west of the Hebrides, an act that violated the submarine protocol and caused significant international controversy. Commander Lemp mistakenly identified the ship as an armed merchant cruiser. Following this, U-30 conducted several war patrols, operating from bases like Kiel and later Lorient in occupied France as part of the 7th U-boat Flotilla. Its patrols took it into the waters around the British Isles, the North Atlantic, and as far as the coast of Newfoundland. The boat was involved in the early stages of the Battle of the Atlantic, attacking Allied shipping convoys and laying naval mines off important ports like Liverpool.

Design and description

As a Type VIIA boat, U-30 was among the first of the iconic Type VII class, which would become the backbone of the Kriegsmarine's U-boat arm. Constructed by AG Weser at its Deschimag shipyard in Bremen, it had a displacement of 626 tonnes surfaced and 745 tonnes submerged. Its propulsion system consisted of two MAN diesel engines for surface running and two Siemens electric motors for submerged travel, granting a surface speed of 17 knots. The boat was armed with five 53.3 cm torpedo tubes (four bow, one stern) and carried up to eleven torpedoes or 22 TMA mines. For surface combat, it was equipped with an 8.8 cm SK C/35 naval gun and a 2 cm C/30 anti-aircraft gun. The crew complement typically consisted of four officers and between 40 to 44 enlisted men.

Summary of raiding history

During its wartime career, U-30 sank 17 merchant ships and damaged two others under multiple commanders, including Lemp, Oberleutnant zur See Hans Cohausz, and Kapitänleutnant Paul-Karl Loeser. Its most significant victim was the *Athenia*, resulting in the deaths of 112 civilians, including 28 American citizens. Other notable successes included sinking the British freighter SS Blairlogie and the Greek steamer SS Diamantis. The submarine also damaged the British tanker MV Regent Tiger. Its patrols, often as part of wolfpack operations like *Prien*, targeted vital Allied supply lines across the Atlantic Ocean, contributing to the tonnage war against the United Kingdom.

Fate

By 1945, U-30 was no longer fit for front-line duty. It was relegated to training functions with the 22nd U-boat Flotilla based in Gotenhafen. As the Red Army advanced during the final stages of the Eastern Front, the boat was scuttled by its crew in Kupfermühlen Bay, near Flensburg, on 4 May 1945, in accordance with the Allied *Regenbogen* order to prevent capture. The wreck was later raised and broken up for scrap in 1948.

Wreck site

The scuttled wreck of U-30 lay in the shallow waters of Kupfermühlen Bay in the Baltic Sea. After the war, the wreck was located and salvaged by a British salvage team in 1948. The operation, part of the broader Allied effort to clear German naval wrecks, involved raising the hull and dismantling it. No major artifacts from U-30 are known to be publicly displayed, and the site where it was scuttled holds no visible remains of the submarine today.
