Meet The F-35 Developmental Test Fleet At Edwards AFB
With the F-35 development program 60% complete and two years to go, the test program is operating at a high pace.
Among the test aircraft at Edwards AFB are five added since the
development started in 2001 to boost a focus on mission-systems flight
trials, largely associated with the aircraft’s complex software. Several aircraft are being outfitted
with the so-called 2B Engineering Test Build (ETB) software patch
designed to correct deficiencies in the platform’s ship-to-ship data
fusion performance. Testers hope to validate this patch in time to
deploy it when the U.S. Marine Corps declares initial operational capability in July.
