Please forgive me if this has been posted. I thought I read somewhere, that Lockheed was proposing a "Connie" equipped with turbo prop-jet engines. Are there any pictures of this prototype. And, would it have had faster crusing speeds than the Elecktra?

Actually the US Navy was test flying it. I think it had the same motors that the C-133 had.
Anyway from what I remember reading in "Tiger Tales' the two Navy frames where aquired by the Flying Tiger lines because they where built with cargo doors. The Navy when they surplused them had cut the wings off outboard of the MLG. So tigers aquired to other Connie wings and put those one the fuselages to create two relatively inexpensive cargo birds with normal plants.
OBAMA-WORST PRESIDENT EVER....Even SKOORB would be better.

I think you will find that Lockheed built 4 of these aircraft, with the P & W engines each having 6,000 Shaft H.P. They were built so that both the USN and Lockheed could gain experience of operating large aircraft with Turbo Props. Two were transferred to the USAF as YC-121Fs and first flew in September 1954
The USN put their R7V-2s through many test achieving a max dive speed of 479 MPH and a max Take Off weight of 166,400 pounds
The fourth R7V-2 was loaned back to Lockheed and fitted with an
Alison 501 Turbo Prop engine in the No 4 position so as to develope the engine for the 188 Electra aircraft. When refitted with it's normal P&W engine it was one of the two transferred to the USAF.
L-188, the story I heard was that Flying Tigers had damaged one of their aircraft up in Alaska and the fuselage was beyond repair so they used one of these Turbo Connies which had become surplus to Requirements to get a cheap fuselage and bolted it onto their wings. Mind you that is only the story I heard.

As I recall, in that TWA exec's book he explains the turboprop conversion was the whole point of the new wing that eventually appeared on the 1649. When P&W (?) dropped the civil T34, Lockheed wanted to drop the development of the new wing, but TWA wouldn't let them.

Quoting NorthStarDC4M (Reply 6): the Turbine powered Connie was offered to airlines as the L1249 Turbo-Constellation. Very little if any interest...

Great thread! I never knew there was a turboprop Connie or that it was offered to airlines and rejected. These are the kind of threads that I joined a.net for - to learn! Thanks a million to everyone on this thread. Appreciate it!
I do quite enjoy a spot of flying - more so when it's not in Economy!

It looks a little strange with turboprops, although still a beautiful aeroplane... and the turboprops do give it even more grace in a weird sort of way.
But it was a piston design, meant to remain that way; the best three engined airliner in the world I'd love to fly on one but I doubt I'd get the opportunity.
