Balalae Airport is a small civil airport on Balalae island operated by Solomon Airlines. It's located in the northwest of the Solomon Islands, part of the Shortland Island Group and south of Bougainville Island (IATA: BAS, ICAO: AGGE). It serves the nearby Shortland Islands and Fauro Island. It's a 1.75 km long sandy coral airstrip only 5 feet (or 1.5 meters) above sea level with a small customs area. It was built during the Japanese occupation of the Solomons to protect the stronghold of Rabaul. During 1943, Admiral Yamamoto planned to arrive on the airport from Rabaul to increase morale after the defeat at the Battle of Guadalcanal. He was shot down while passing Bougainville Island during Operation Vengeance, during the Guadalcanal campaign.
