Krymsk Air Base — Krymsk, Russia

NOI is the code for Krymsk Air Base, a Russian military airfield located near Krymsk in Krasnodar Krai. The base has historically supported Russian air force operations in the North Caucasus and Black Sea region, including fighter and bomber squadrons at various points in its history. As a military facility, NOI does not offer commercial passenger service, and public information about its current operational units is limited, consistent with the restricted nature of Russian defense installations. The surrounding Krymsk area is otherwise known for agriculture, and the base's presence has periodically drawn attention during regional military exercises and geopolitical tensions.
