Does anyone know any details concerning the Grumman Lunar Module-B/Space Tug that was part of the Integrated Man Space Flight Program? I have found information that says its diameter was 22 feet and other information that says it was 15 feet. Did earlier concepts of the space shuttle have a cargo bay that could accomodate payloads as wide as 22 feet? Did the dimensions of the Lunar Module-B/Space Tug change when the dimensions of the space shuttle cargo bay changed to 15 feet by 60 feet? Concept art suggests that the space tug is as wide as the space shuttle cargo bay.

Other information I have found states that the Lunar Module-B/Space Tug would have been lifted to LEO by Saturn V rocket.

So far i know it wend this way

1968 the "Integrated Man Space Flight Program"
make use of Saturn V to Launch the Tugs in space, later refuel by shuttle
so its diameter was 21.68 ft (6.61 m ø)

later with the Saturn V production was chancels
in 1970 the Space Shuttle became Launcher for Tug
So its diameter became 15 ft by 59 ft (4,5 meter ø by 18.0 m)

those picture show Grumman Lunar Module-B/Space Tug ?
i always thought that look more like LM, only with bigger Descent Stage and no legs...

Thanks for the response. With little snippets of information here and there its sometimes difficult to put the pieces together. A Bellcomm document talks about launching tugs using Saturn V INT-21 and then another talks about the space shuttle and so I thought that an earlier version of the shuttle had a wider cargo bay.

I presume what is depicted is the LM-B/Space Tug described in the documents. The Corbis image library said that it was a Grumman concept.

Mark Wades' Astronautix web site talks about a Boeing space tug, but its appearance is different.

So if anyone has any additional information, feel free to jump in.

oh there Zillion proposal for this Space Tug

Lockheed reusable Agena stage with stap on tanks
Grumman LM variants
Boeing
NASA Integral like MSFC
even ELDO was ask by NASA for Tug Proposal

by the way Wat source you got Triton ?

I don't have them with me right now, but they are some documents that I requested from David who runs the Beyond Apollo blog site, formerly Altair VI. One is a multiple page memo created by Bellcomm, one is a document titled Integrated Man Spaceflight Program, and then there is another whose title escapes me at the moment published in a magazine. Aeronautics and Astronautics, I believe is the name of the magazine.

Space Tug launch configuration found in

Pioneering In Outer Space
Heinemann Educational Books, London,
Shakespeare Head Press, Scientific Services Pty., and S. T. Butler, 1971

From the book
Significant improvements in lunar exploration would be introduced with the advent of the Space Tug. In delivering payloads to the Moon, the Space Tug would provide improved performance to the Saturn V launch vehicle by adding a fourth stage to the three-stage rocket. An unmanned launch would initiate this operating mode by transporting a Space Station Module to lunar polar orbit at approximately 60 miles altitude. Manned launches would deliver Command Modules, Space Tugs, and support cargo to the orbiting station. (Command Module portion skipped) For the lunar landing, the Space Tug propulsion module, crew module, landing legs and other appropriate support kits would descend to the lunar surface for missions of 14to 28 days.

Apparently, Space Tug propulsion modules were to be used as the landing platforms for the lunar base modules as well as for placing the orbital station modules in their intended orbits.

Yeah, that was one idea. There's some decent artwork around of tall, cylindrical lunar landers (see the second illustration in the first post--there's more like it).

But keep in mind that "Space Tug" was a concept, and a bunch of designs were proposed, but nothing was ever selected. So this is one of a bunch of concepts. Then the project was canceled.
