This Defense Intelligence Reference Document, prepared by the Defense Intelligence Agency and dated 8 March 2010, was produced under the Advanced Aerospace Weapon System Applications (AAWSA) Program. It gives a historical and technical review of how to reach space and return. It covers hypersonic gliders, air-breathing and rocket propulsion, thermodynamics and materials, and launch options. It argues that reliable, schedulable access to low Earth orbit is mainly a hardware and propulsion problem rather than a technology one.

UNCLASSIFIED/ /PS"-. 9PPl!ltllt t!l91!! 9HLY but we believed new launch complexes would be required to achieve the desired launch rates and to accommodate sustained-use vehicles. This all seems impossible given today's launch operations and preparation time, but in 1964 it was considered possible both in the United States and in the former Soviet Union. It appears that two known companies proposed on the MOL support system, as shown in Figure 38. The Model 176 preliminary launches were to be on a Martin Titan IIIC. This was adequate for testing, but the minimum launches for one year of support of MOL was 74 launches. That 74 Titan IIICs could achieve a sustained manufacturing rate or a sustained launch rate was not considered. So both Lockheed Aircraft and McDonnell Douglas proposed a self-sustained operational system using recoverable lateral propellant tanks. There were no engines on the lateral tanks as there were in the aircraft since they were simply drop tanks. Lockheed Star Clipper circa 1964 ~ McDonnell Douglas Model 176 circa 1964 Figure 38. A 1964 MDC Astronautics, St. Louis, Briefing Defined a MOL Support System With 10 Launchers That Could Fly 100 Missions a Year for 15 Years. Lockheed Aircraft and McDonnell Douglas both had candidates. Atmospheric Variations The published approach to determining glide range is to assume the global atmosphere definition is a series of concentric, constant-density shells. The 1962 standard atmosphere follows the 1959 standard atmosphere and previous standards. NAVAIR-5- lC-59, Harold Crutchner, 28 details the Northern Hemisphere by month for every 10 degrees of longitude from 1931 to 1964. According to Crutchner, these atmosphere descriptions were not intended to be engineering atmospheres but to be standards to ensure that aircraft flying globally would have adequate altitude clearance. The 1962 atmosphere represents the average of all daily reports by the worldwide reporting stations between +30 and +60 degrees latitude for the spring and fall equinox minus one month to plus one month represented as a +45 degree average atmosphere. 35 UNCLASSIFIED/ ,era~ 8FFIIIAL ~:!II!! 8HLY
