D.2 Atlas Launch and Performance History Atlas space-launch vehicles, originally manufactured by General Dynamics and currently by Lockheed Martin, derived from the Atlas ICBM series developed in the 1950s. The primary one-and-one-half-stage vehicle played a major role in early lunar exploration activities (the unmanned Ranger, Lunar Orbiter, and Surveyor programs), and planetary probes (Mariner and Pioneer). Table 40 shows a summary of Atlas configurations since the beginning of the program.[1°1 Table 40.

During that time, some Atlas Ds were modified as space-launch vehicles in the LV series: LV-3A, 3B, and· 3C. The Standardized Launch Vehicle (SLV) series derived from a need to reduce lead times in transforming Atlas missiles to space-launch vehicles. The SLV series began with the SLV-3 vehicle, which used an Agena upper stage. The G and H vehicles evolved from the SLV series. Eventually the I, II, IIA, and IIAS configurations were developed with the aim of also supporting commercial launches. 9/10/96 101 RT!
Vision Description (EN)
Page 101 of a technical report on Atlas launch vehicles. The page begins with section D.2 heading and a paragraph describing the history and development of Atlas space-launch vehicles derived from the Atlas ICBM series. The primary visual element is Table 40 (Summary of Atlas Vehicle Configurations), which occupies the central portion of the page. The table lists approximately 17 Atlas configurations (A through IIAS) with their technical descriptions, including staging arrangements, upper stages, and avionics modifications. Below the table is a continuation paragraph explaining the developmental and operational history of these configurations, from early ICBMs through standardized launch vehicles to commercial variants. Footer markings show date "9/10/96", page number "101", and document identifier "RTI".
