Bagram Airfield — Bagram, Afghanistan

OAI is the code for Bagram Airfield in Afghanistan, historically one of the most significant military airbases in the world due to its central role during the Soviet occupation and later as the primary hub for United States and NATO forces during the war in Afghanistan from 2001 onward. Bagram featured extensive military infrastructure, including large runways capable of handling heavy transport and combat aircraft, and served as a logistics, detention, and operations center for coalition forces. The United States withdrew from Bagram in July 2021 as part of the broader American military withdrawal from Afghanistan, and the airfield subsequently came under the control of the Taliban following their takeover of the country. Its current operational status and use are administered by Afghanistan's Taliban authorities rather than by NATO or coalition forces.
