USS Mount Vernon (AP-22) was a troop transport that served with the United States Navy during World War II.

The Atlantic Conference was held on 9 August 1941 in Placentia Bay, Newfoundland, between Prime Minister Winston Churchill and President Roosevelt.

Besides the "official" agenda, Churchill hoped to obtain considerable assistance from the USA, but the American President had his political hands tied.

On 5 September the President assured the British leader that six vessels would be provided to carry twenty thousand troops and would be escorted by the American Navy.

The chief of Naval Operations ordered troop ships divisions seventeen and nineteen, on 26 September 1941, to prepare their vessels for approximately six months at sea.

The convoy consists of Aircraft Carrier Ranger (CV-4) and troopships, Mount Vernon (AP-22), Wakefield (AP-21), West Point (AP-23), Orizaba (AP-24), Leonard Wood (AP-25) and Joseph T. Dickman (AP-26) and is destined for Basra Iraq.

At 650 on 21 December, the Mount Vernon and USS Orizaba detach from the convoy headed for Bombay, and are bound for Mombasa.

[5][13] [14] The USS Mount Vernon departs Singapore on 14 January for Aden, where she embarked Australian veterans of the Mediterranean Theatre for transportation to Ceylon and Fremantle.

[17] In Australia she embarked civilian and military escapees from the Philippines, and naval survivors from ships sunk in the Battle of Makassar Strait.

After calls in Adelaide, South Australia and Wellington, New Zealand, Mount Vernon sailed for San Francisco, arriving 31 March.

[29][30] On 4 June 1944, Mount Vernon began a series of voyages to United Kingdom ports and the Mediterranean, carrying men for the massive buildup on the European continent which would bring Germany to her knees.
