Operation Deadlight

After the surrender, political discussions continued between the Allies concerning the final disposal of the surviving German naval vessels, the result of which was an agreement to retain 30 U-Boats in total, to be divided equally between the UK, the USA and the USSR.

[1] The Royal Navy carried out the operation, and planned to tow the submarines to three areas about 100 miles (160 km) north-west of Ireland and sink them.

[2] When Operation Deadlight began, the navy found that many of the U-boats were in poor condition from being moored in exposed harbours while awaiting disposal.

U-505 was earmarked for scuttling, but American Rear Admiral Daniel V. Gallery argued successfully that she did not fall under Operation Deadlight.

[5] In the late-1990s, a firm applied to the British Ministry of Defence for salvage rights to the Operation Deadlight U-boats, planning to raise up to a hundred of them.

[10] On 3 October 2007, an Irish diver, Michael Hanrahan, died whilst filming the wreck as part of the salvage project.
