The borough has a total area of 12,022 square miles (31,140 km2), of which 6,550 square miles (17,000 km2) is land and 5,472 square miles (14,170 km2) (45.5%) is water. Most of the land area belongs to Kodiak Island, but a thin strip of coastal area on the western part of the Alaska Peninsula and other nearby islands (Afognak Island, Shuyak Island, Marmot Island, Raspberry Island, Little Raspberry Island, Whale Island, Spruce Island, Woody Island, Uganik Island, Sitkalidak Island, Tugidak Island, Sitkinak Island, Chirikof Island, and the Semidi Islands) are also in the borough. The waterway between the island and mainland is known as the Shelikof Strait. South of the island are the open waters of the Pacific Ocean, so the site is considered good for launching certain types of satellites. The Kodiak Launch Complex is ideal for putting satellites in Molniya and polar orbits.
