SSS is the airport code for the airstrip at Siassi, on Umboi Island in the Morobe Province of Papua New Guinea, in the Bismarck Sea. Umboi, known locally as Siassi, is the largest of the volcanic islands lying between the Papua New Guinean mainland and the island of New Britain, separated from them by the Dampier and Vitiaz Straits. It is a rugged, forested volcanic island of mountains, villages and coast, ringed by smaller islands and reefs, home to communities with their own traditions. Siassi is a remote local centre rather than a tourist destination, of interest for its dramatic island scenery and the seafaring cultures of the Siassi islands, long known as traders across these waters. Siassi is reached by small aircraft to its airstrip and by boat across the straits, with connections through Lae and other centres. The climate is hot, humid and tropical, with heavy rainfall.
