MOL’s mysteries

The Air Force’s Manned Orbiting Laboratory (MOL) of the 1960s is finally being declassified. A significant document release this summer included hundreds of illustrations of the overall laboratory, many of its components and subsystems, and also proposed variants and upgrades. As a result, it is now possible to gain a good understanding of how MOL was configured and how it operated.

When MOL was cancelled in summer 1969, it was a major financial blow to McDonnell Douglas.
Nevertheless, many MOL questions remain unanswered and will have to await further document declassifications or former MOL personnel discussing the program and their role in it. For example, what contractors were involved in the development of MOL and what were their roles? How did they work together, especially when some parts of the project were unclassified and some were deep black.
Because MOL was an unusual program with both unclassified and classified elements, many details about it were released while it was under development, although this conveniently helped to distort the image of what MOL was actually for. Based upon the unclassified parts alone, it is clear that MOL was a large and expensive project. In 1967, the Air Force awarded fixed-price incentive-fee contracts to Douglas Aircraft for $674.7 million and McDonnell for over $180 million. Douglas was responsible for the laboratory module’s unpressurized and pressurized sections and McDonnell for the Gemini B spacecraft. Other sources indicate that McDonnell was supposed to provide four Gemini B spacecraft with options for two or more later. Douglas signed subcontracts for such components as the waste management system, attitude control, and life support. When Douglas and McDonnell merged later that year, the combined company was responsible for a very large Department of Defense space contract. Thus, when MOL was cancelled in summer 1969 it was a major financial blow to McDonnell Douglas.
