This was a CH-47A converted in 1969 to the BV-347 prototype as an entry for the Heavy Lift Helicopter (HLH) requirement, first flying at Vertol's test facility at Eddystone, PA in May 1970. Phase I changes included upgrades to CH-47C standards, four blade rotors, fuselage stretch, Phase II adding variable incidence wings for extra lift. Hydro-mechanical rotor controls were later replaced with a fly-by-wire system integrating wing and rotor controls automatically. Although successful the Army could not feasibly modify its entire Chinook fleet, but some improvements carried over to the CH-47D

Delivered to the US Army as CH-47C 70-15026 in 1971. Rebuilt as CH-47D 91-0252 c/n M3401. To the Greek Army as ES-922 in 2016.

Stored on the undulating apron of Colmenar Viejo, this is one of the recently retired CH-47Ds of the Spanish Army, most of which were found in storage at the time. The type has been replaced by the CH-47F.

One of three Chinooks received by the Argentine Air Force in January 1980. One (H-92) was written off in January 1982 and both of the survivors are now in the care of the museum at Moron. H-91 is now restored and on display in Antarctic colours while H-93 remains under restoration and will ultimately be displayed in the green/brown camouflage worn during the early 1980s.
