The Republic of Singapore Air Force (RSAF) is the aerial service branch of the Singapore Armed Forces (SAF) responsible for controlling and defending the airspace of the country, and providing air support to the Army and Navy. It was established in 1968 as the Singapore Air Defence Command (SADC) before renaming to its current name in 1975. As the most powerful air force in Southeast Asia, the RSAF has undertaken a significant role in Singapore's military defence strategy since its formation. The RSAF has been considered by various analysts as being the most technologically advanced air force in the region, with the ability to act as a strong deterrence from potential hostile nations as well as defending the airspace of the island city-state. In the event of national exigencies or a full-scale war, the RSAF will be the first leading the charge when conflict arises, in combat situations. As of 2021, the RSAF uses four air bases domestically, Paya Lebar, Changi, Sembawang, and Tengah, as well as at civilian airport Seletar. The RSAF has overseas detachments in various countries, most notably in Australia, the United States and France. As of 2021, the RSAF has a strength of 8,000 active personnel. From Wikipedia
