And still the US Navy denies any B-29 aircraft or parts are still there !

Looks like 3 hulks remain at or near China Lake. In addition to the lake and Echo range airframes sabrejet lists in post #8, there is one in the “museum” area, 44-70102 Here’s Hopin . Incomplete. Had the top cut open to retrieve the tunnels running through the bomb bay area for other museum aircraft (Seattle IIRC).

The Echo range aircraft was subject to severe overpressure from bomb blasts and is seriously “oil canned”. Incomplete.

I do know the Navy has gotten tired of dreamers and collectors asking if they can come and get a B-29, or parts thereof. The days of getting an intact airframe are long gone. If someone really had the money, I offer the airframes at Aero Trader, or several on outside display would be much better projects.
