HMCS Mahone (pennant J159) was a Bangor-class minesweeper constructed for the Royal Canadian Navy during the Second World War.

The engines produced a total of 2,400 indicated horsepower (1,800 kW) and gave a maximum speed of 16.5 knots (30.6 km/h; 19.0 mph).

[2] Mahone was armed with a single quick-firing (QF) 4-inch (102 mm)/40 caliber Mk IV gun mounted forward.

[5] In September 1943, Mahone was among the warships deployed as part of the Canadian force to break up Operation Kiebitz, the German plan to breakout prisoner of war U-boat captains from a camp in Canada.

On 29 January 1944, the minesweeper was rammed by the merchant vessel SS Fort Townshend off Louisburg, Nova Scotia.

After working up in Bermuda, the vessel returned to Halifax in July 1945 and remained in service there until being paid off on 6 November 1945.

[5] During the Korean War, the vessel was reacquired by the Royal Canadian Navy and given the new hull number FSE 192 and re-designated a coastal escort.

[8] However, the ship never recommissioned and remained in reserve at Sydney until 29 March 1958 when Mahone was formally transferred to the Turkish Navy.
