## Description

A single 1,524-metre runway (17/35) and military-only traffic define Henry Post Army Airfield (IATA: FSI, ICAO: KFSI) at Fort Sill, Oklahoma. Established as Post Field in 1917, it is the oldest continuously operating U.S. Army airfield and the birthplace of Army combat aviation. There is no commercial cargo handling or freight terminal here. Air freight for the Lawton area moves by road via Will Rogers World Airport in Oklahoma City (OKC), about 140 kilometres to the northeast.
