The Air Force recently signed an addendum to the Eglin Base Realignment and Closure 2014 record of decision for two temporary actions – shifting the primary runway to Runway 01/19 and allowing a temporary increase in previously limited F-35 operations for the construction-related closure of Runway 12/30, and the Department of the Navy’s proposal to add 15 backup aircraft inventory (BAI) F-35C aircraft at Eglin AFB.
