Fruitful cooperation
After undertaking parallel studies for a successor to the similar Harrier
GR.Mk 3 and AV-8A in service with the Royal Air Force and U.S. Marine Corps.
McDonnell Douglas and British Aerospace decided to join forces for the
design of an advanced version of the Harrier, and the resulting YAV-8B
prototype first flew in November 1978.
Much enhanced Harrier
The AV-8B Harrier II entered USMC service in October 1983. By comparison
with the basic Harrier, it has a more powerful engine aspirated via larger
inlets, a revised fuselage with a fighter-type cockpit, a completely new
and larger wing of supercritical section and graphite epoxy construction
(with larger flaps, drooping ailerons, and leading-edge root extensions
for improved maneuverability), better underfuselage life-improvement
devices, and seven hardpoints for weapon carriage. From 1989 new aircraft
have had improved night attack capability through provision of night vision
goggles, a moving map display, and a head-up display accommodating FLIR
imaging.
Principal versions
AV-8B Harrier II (production model, of which the USMC needs 328), and TAV-8B
Harrier II (two-seat version with full combat capability).
Principal user
