HMCS Beauharnois was a modified Flower-class corvette that served with the Royal Canadian Navy during the Second World War, primarily in the Battle of the Atlantic.

After the war it was sold to a Jewish resettlement movement and eventually made its way into the nascent Israeli Navy.

[2][3][4] The "corvette" designation was created by the French as a class of small warships; the Royal Navy borrowed the term for a period but discontinued its use in 1877.

[8] She was laid down as Buckingham before her name was changed to Beauharnois[9] on 8 November 1943 by Morton Engineering & Dry Dock Co. in Quebec City.

The two ships were used to smuggle Jewish immigrants into British-held Palestine as part of the Aliyah Bet.
