What was the duration of the war that was in progress when the USS McAnn first served in the Atlantic Ocean?
World War II World War II (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the world's countries—including all of the great powers—eventually forming two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. In a state of total war, the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the distinction between civilian and military resources.
Panama during World War II The history of Panama during World War II begins in 1939. Due to the American-controlled Panama Canal cutting across the center of the country, Panama was of major strategic importance to the Allied war effort, as well as the most important strategic location in Latin America during World War II. It provided an invaluable link between the Atlantic and Pacific Oceans that was vital to both commerce and the defense of the Western Hemisphere. Therefore, the defense of the Canal Zone was the United States' chief concern in the American Theater. Panama never received Lend-Lease assistance, but in return for the rights to build military infrastructure within Panamanian territory, the United States undertook large-scale public works projects, which did much to modernize the country and boost the economy.
