Ernest Harmon Air Force Base
The United States established an administrative army air force and coast defense base named Fort Pepperrell (no airfield) in St. John's, along with a deepwater naval base and naval aviation field at Argentia on the Avalon Peninsula. The northeast coast of Newfoundland and the strategically important Strait of Belle Isle were left exposed, therefore military planners sought to establish an army air force base on of land at the northeast end of Bay St. George near the coastal hamlet of Stephenville. The 76th Congress approved the 99-year lease and in April 1941, construction began on a deepwater port and adjacent air field.
