Wonsan Kalma Airport — Wonsan, North Korea

Wonsan Kalma Airport, coded WOS, is located near the city of Wonsan on North Korea's east coast and is associated with the Kalma peninsula beach resort development promoted by state authorities in recent years. North Korea's aviation sector operates under tight state control, and independent verification of civilian operations, schedules, or passenger volumes at this facility is very limited. Publicly available information about Wonsan Kalma Airport is scarce and often unconfirmed by independent sources, reflecting the broader information restrictions surrounding North Korean infrastructure. The airport is understood to serve both aviation and tourism-related purposes tied to the nearby resort area, though details remain difficult to substantiate.
