Making use of weather cover, the Japanese made a two-day aerial bombing of the continental United States for the first time in history on Dutch Harbor in the city of Unalaska, Alaska on June 3, 1942. The striking force was composed of Nakajima B5N2 "Kate" torpedo bombers from the carriers and . However, only half of the striking force reached their objective. The rest either became lost in the fog and darkness and crashed into the sea or returned to their carriers. Seventeen Japanese planes found the naval base, the first arriving at 05:45. As the Japanese pilots looked for targets to engage, they came under intense anti-aircraft fire and soon found themselves confronted by Eleventh Air Force fighters sent from Fort Glenn Army Air Field on Umnak. Startled by the American response, the Japanese quickly released their bombs, made a cursory strafing run, and left to return to their carriers. As a result, they did little damage to the base.
