Sevastopol International Airport / Belbek Air Base — Sevastopol, Ukraine

Sevastopol International Airport, also referenced as Belbek, uses the code UKS and is located on the Crimean Peninsula, a territory whose sovereignty status remains disputed following Russia's 2014 annexation, an action not internationally recognized by most countries, which continue to regard Crimea as part of Ukraine. Belbek has historically functioned as a military airbase alongside limited civilian operations. Since 2014, and further amid the ongoing Russia-Ukraine conflict, the facility's operational status has been significantly affected, and independent verification of any current civilian flight activity is difficult to obtain. UKS should not be assumed to support normal commercial air travel under present conditions.
