Cape Romanzof LRRS Airport — Cape Romanzof, United States

CZF marks Cape Romanzof LRRS Airport, a remote airstrip on a coastal headland in western Alaska overlooking the Bering Sea, near the Yukon-Kuskokwim Delta. LRRS stands for Long Range Radar Site, and this facility is part of the Alaska Radar System built during the Cold War to provide early-warning air defense coverage across the state's remote northern and western coastline. The airfield supports personnel and supply flights to the radar installation, which today operates largely unmanned with periodic maintenance visits, and it also serves nearby Yup'ik communities such as Scammon Bay for essential transportation. CZF's isolated location, harsh weather, and gravel runway are typical of Alaska's network of bush and military support airstrips.
