"Dreadnought" was put up for sale on 31 March 1920 and sold for scrap to Thos W Ward on 9 May 1921 as one of the 113 ships that the firm purchased at a flat rate of £2. 10/- per ton, later reduced to £2. 4/- per ton. As "Dreadnought" was assessed at 16,650 tons, she cost the shipbreaker £36,630 though another source states £44,750. She was broken up at Thos W Ward's new premises at Inverkeithing, Scotland, upon arrival on 2 January 1923. Very few artefacts from "Dreadnought" survived, although a gun tompion is in the National Maritime Museum at Greenwich.
