Of the 74 German ships at Scapa Flow, 15 of the 16
capital ships, 5 of the 8 cruisers, and 32 of the 50 destroyers were sunk. After complaints from locals that the wrecks were a hazard to navigation, a salvage company was formed in 1923, which raised four of the sunken destroyers. At about this time, the entrepreneur
Ernest Cox became involved. He bought 26 destroyers from the Admiralty for £250 (equivalent to £ in ), as well as and
Hindenburg. and minor salvage is still carried out to recover small pieces of steel. This
low-background steel is used in the manufacture of radiation-sensitive devices, such as
Geiger counters, as it is not contaminated with
radioisotopes, having been produced before any chance of
nuclear contamination. The last living military witness to the scuttling of the fleet was
Claude Choules, who died on 5 May 2011 aged 110. Choules was the last known living combat veteran of the First World War. An eyewitness account of the scuttling and the subsequent angry meeting between Reuter and Fremantle was published in 2015 by the family of Hugh David, who died in 1957. In 2019, the three battleships
Markgraf,
König and
Kronprinz Wilhelm were sold on eBay (by the retiring diving contractor Tommy Clark) for £25,500 each to a Middle Eastern company. The cruiser,
Karlsruhe, sold for £8,500 to a private bidder in England. In 2001, seven of the remaining wrecks (three battleships and four cruisers) were scheduled under the
Ancient Monuments and Archaeological Areas Act 1979 (as SM9298 and SM9308). Divers are allowed to visit them, as long as no damage occurs or objects removed. In 2025, protection was extended to the entire site when the Scottish government designated it as a
marine protected area, which makes it a criminal offence to remove items from any of the wrecks. == Centenary anniversary event ==
