About Port of Dutch Harbor

This U.S. harbor on Amaknak Island serves as a key fishing and processing hub. It accommodates a significant volume of fishing vessels and is equipped for their support.

Background
Dutch Harbor is a harbor on Amaknak Island in Unalaska, Alaska. It was the location of the Battle of Dutch Harbor in June, 1942 when the Imperial Japanese Navy attacked it just seven months after the attack on Pearl Harbor in Hawaii. To this day, it remains one of the few sites in the United States to be subjected to an aerial bombardment by a foreign power.
