HMS Wild Swan was an Admiralty modified W-class destroyer built for the Royal Navy. She was one of four destroyers ordered in 1918 from Swan Hunter and Wigham Richardson, Wallsend-on-Tyne under the 14th Order for Destroyers of the Emergency War Program of 1917–18. She was the second Royal Navy ship to carry the name, after the sloop HMS Wild Swan in 1876. Like her sisters, she was completed too late to see action in the First World War.

HMS Broke was a Thornycroft type flotilla leader of the Royal Navy. She was the second of four ships of this class that were ordered from J I Thornycroft in April 1918, and was originally named Rooke after Rear Admiral Sir George Rooke of the Dutch Wars and the Battle of Vigo Bay.
