In the late 50's Douglas was working on a 500000 lb cargo plane call the C-132 Globemaster 3. It was power by (get this) four 15000 hp T57 turboprops, yes the turboprop version of the J57. Thought you guys my want to know about this plane.

I don't know that it officially got the Globemaster III name, but it was a proposal that ultimately wasn't accepted. I believe the Air Force thought it was too much airplane for the airlift mission at the time. Ultimately the Air Force bought the C-133 and got those in relatively limited numbers.
The C-132 would have looked like a scaled down C-5 but with turboprop power instead of the huge turbofans the Galaxy has. Incidentally, the C-17 is now called Globemaster III. The C-124 was officially the Globemaster II but the military types never called her that.

Then I go some wrong information from the net. After looking in the 1958 Jane aircraft book about the T57 which was going to power the plane. I looked it up on yahoo and the it wass called the Globemaster III and they said it was 500000 lb. So this time it is that web site mistake for once.

I believe the T57 was an entirely different engine and wasn't based on the J57 engine at all. It just happened to be the 57th turboprop engine given a military designation.

Incorrect information on the internet? Say it ain't so, Joe.

KC135, your reference site suggest a MTOW of more than 460,000 lbs with growth potential to 560,000, so it indeed sounds like a 500,000 lbs class airplane.
Now if you are talking about useful load or payload...

There is a photograph in Phil Chinnery's 'Desert Boneyard' book of a C-124C Globemaster II 52-1069 in MASDC which had been converted into a turbo-prop engine test bed. It had a massive conical fairing grafted to the nose which gave some idea of the size of the engines it tested in its career. Did the T-57 get as far as flight testing?

You are right! I made a mistake the J-57 was base on the T45 not the T57. Please for give my mistake?

While doing research for the C-124 book I wrote, which was published by Steve Ginter, I got a package of photos from Harry Gann and among them was a photo of the C-124 you mentioned, in flight with the T57 engine running. The full extent of the test program is unknown to me.
