Cold Bay Airport (IATA: CDB, ICAO: PACD) is a public-use airport located in Cold Bay, Alaska, on the Alaska Peninsula near the tip of the Aleutian chain. It serves as an essential lifeline for this small, isolated community, which has no road connections to the broader Alaska highway system. The airport is notable for possessing one of the longest runways in Alaska, a legacy of its origins as a major World War II military airfield known as Fort Randall. This extensive infrastructure makes it a viable emergency diversion point for transpacific flights crossing the North Pacific. Petersen Field, as it is sometimes referenced historically, is owned by the State of Alaska and primarily serves general aviation and scheduled commuter service. It plays a critical role in the region's transportation network, providing the only reliable access to Cold Bay for residents, cargo, and emergency services.
