A team of five amateur divers from Cork discovered this submarine in good condition in 27m of water just off Roches Point on 6 November 2010 after a 12-month search. Diver Ian Kelleher said they were very surprised and ecstatic to find it with little obvious explosive damage.

Positive identification was possible when they found its number stamped on a propeller. Mr Kelleher, a chemistry student, said that two days before Christmas, the dive team laid a plaque of remembrance near the propellers as a memorial to the 27 German submariners who died.

They plan to return to the site over the coming weeks and continue their research into the submarine and its crew, including trying to contact relatives of the crew

Allen Tony15/02/2013The wreck was finally found during a commercial hydrographic survey in 2010. Reports in November 2010 , indicated that sports divers had begun visiting the wreck. Video footage of the remains of UC-42 were featured on RTE (Irish Television) News on January 24th, 2011. Since then there have been persistent reports of looting on this site - a war grave. On the 27th of July 2012 the following Radio Navigational Warning (RNW) was broadcast - IN THE INTEREST OF SAFETY AND TO FACILITATE OPERATIONS IN CONNECTION WITH THE SUNKEN VESSEL UC42.

About Owners
 
Imperial German Navy - Kaiserliche Marine (1903-1919)

Kaiserliche Marine or the German Imperial Navy is the name for the German Navy between 1903 and 1919. Most of the ships had a prefix SMS, Seine Majestäts Schiff, which is the equivalent of HMS, Her/His Majesty's Ship.

This Navy should not be confused with Reichsmarine (1920-1935) or Kriegsmarine (1935-1945).
 
About Builders
 Vulcan A. G. (Stettin & Hamburg), Hamburg
Founded as Vulcan Werft in Stettin in 1851.

In 1857 the shipyard was renamed Stettiner Maschinenbau AG Vulcan.

As Stettin became too small, a new shipyard was built in Hamburg between 1907 - 1909.

In 1911 renamed Vulcan-Werke Hamburg und Stettin Actiengesellschaft.

In 1928 the Hamburg company merged with other companies to Deschimag concern. The Stettin company was taken over by Howaldtswerke AG.

  History  
 
Racey Carl24/01/2011UC-42 sailed on her last patrol on 1 September 1917. On 31 October 1917 Torpedo Boat TB 055 was accompanying minesweepers operating at the entrance to Cork harbour. At 1500 hours an oil track was seen floating on the surface of the water. Following it to its source, TB 055 used its hydrophone to see if the oil was coming from a submarine. Loud mechanical sounds, of "hammering" and "turbine-like noises" were reported and, believing this to be a U-boat, a marker buoy was dropped, followed shortly after by a depth charge.

Following detonation of the charge, TB 055 returned to the area and found that the volume of floating oil had increased, and there were bubbles rising to the surface. TB 055 signalled the nearby armed minesweeper HMT Sarba for assistance. Sarba used her hydrophone but de tected no sounds from the presumed submarine. A second depth charge was dropped and Sarba remained on station overnight. The following morning HMD Sunshine and TB 058 swept around the spot, to confirm that the incident had not been a false alarm caused by old wreckage. On 2 November oil was still coming to the surface and dockyard drivers arrived to inspect the assumed wreck. The divers reported aGerman U-boat lying on the seabed with her stern blown off, and a brass plate on her conning tower reading "C42, 1916" identified her as UC-42.

No survivors were ever reported even though some of the hatches were found to have been opened. It was thought likely that the submarine had been sunk by one of her own mines detonating under her stern while mine-laying. This location proved incorrect. The actual wreck was located on 6 November 2010 in 27m of water just off Roche's Point. It was found with "little obvious explosive damage". When the sinking and identification of the submarine was reported, the British Admiralty requested an identifiable item from the vessel for verification purposes, and in December 1917 divers recovered the telephone buoy from the conning tower. The Royal Navy's Naval Intelligence Department were aware of submarine's 1 September departure date from Belgium and were sceptical about the hammering and engine noises reported by TB 055.

The Admiralty reported that "The longest known cruise of a UC boat in home waters is 24 days, so UC-42 must have been dead long before TB 055 and Sarba dropped the depth charges" From Wikipedia, the free encyclopedia
