Tiksi Airport — Tiksi, Russia

IKS is Tiksi Airport, an isolated facility in the Sakha Republic of Russia, located on the coast of the Laptev Sea well above the Arctic Circle. Tiksi has historically served as a strategic Arctic outpost, supporting Northern Sea Route logistics, scientific research stations, and military presence in the harsh polar environment. IKS provides an essential lifeline for the small settlement, since surface transport to the region is extremely limited given the permafrost terrain and long winters. The airport's infrastructure reflects Soviet-era Arctic development priorities, and it continues to support both civilian resupply flights and activities tied to Russia's ongoing strategic interest in Arctic shipping routes and resource access.
