The beached ships were later dispersed to the allied navies, but most of the sunken ships were initially left at the bottom of Scapa Flow, the cost of salvaging them being deemed to be not worth the potential returns, owing to the glut of scrap metal left after the end of the war, with plenty of obsolete warships having been broken up.[32] 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.
