Revocation of Class D and E Airspace; Fort Sill; and Amendment of Class D and E Airspace; Lawton, OK

This action removes Class D airspace, Class E airspace designated as a surface area, and Class E airspace designated as an extension to a Class D and Class E airspace at Henry Post Army Air Field (AAF), Fort Sill, OK; amends Class D airspace and Class E airspace designated as a surface area at Lawton-Fort Sill Regional Airport, Lawton, OK; and amends Class E airspace extending upward from 700 feet above the surface at Lawton-Fort Sill Regional Airport and Henry Post AAF. This action is due to the closure of the air traffic control tower (ATCT) at Henry Post AAF. The name of Lawton-Fort Sill Regional Airport and the geographic coordinates of Henry Post AAF are also being updated to coincide with the FAA's aeronautical database, and the outdated term "Airport/Facility Directory" is replaced with the term "Chart Supplement."
