Rabaul is a town in Eastern New Britain, Papua New Guinea. Japanese forces landed on Rabaul on 23 February 1942, capturing it in February of that year. The former Australian territory was transformed into a major Japanese naval and air installation. The Japanese heavily relied on it, and used it as a launching point for Japanese reinforcements to New Guinea and Guadalcanal. Throughout the Solomons Campaign, neutralizing Rabaul became the primary objective of the Allied effort in the Solomons.
