Several flight test key milestones were accomplished since the
The F-35 program flew the most flights ever recorded on one day
(May 6) when a combined total of eight test flights were completed
at all three of its flight test locations. (Edwards AFB, CA; Fort
Worth, TX, and Naval Air Station Patuxent River, MD.)
The U.S. Air Force accepted into its fleet the first of a
planned 1,763 production-model F-35 Lightning II stealth fighters
when AF-7 was delivered to Edwards Air Force Base, CA, on May

(LRIP) lot one delivered.
The first F-35A production aircraft that will be delivered to
Eglin Air Force Base, FL, accomplished its first flight on May 6.
Known as AF-8, the aircraft will be delivered to Eglin for pilot
and maintainer training later this year. This jet is the first
aircraft to fly from Low Rate Initial Production lot
The second F-35C carrier variant (CV), known as CF-2, completed
its first flight April 29. Later this month it is scheduled
to be delivered to the F-35 test fleet at Naval Air Station
Patuxent River, MD, (PAX).
