Department of the Air Force Report, 1996

U.S. Department of War · 1996-09-10 · 181 pages · text from the file's own layer

This final report, dated September 10, 1996, was prepared by the Research Triangle Institute for the Department of the Air Force's 45th and 30th Space Wing safety offices. Titled Modeling Unlikely Space-Booster Failures in Risk Calculations, it shows how rare Mode-5 failures, in which a rocket veers well off its intended flight line, are modeled in the DAMP risk-analysis program. An appendix lists Atlas, Delta, Titan and Thor launch and failure histories through August 1996.

From the source:Release of 2026-05-08 Incident: 9/10/96, N/A. This report describes the Modeling of Unlikely Space-Booster Failures in Risk Calculations, documenting historical launch failure modes and recommending corrective actions to address them using novel modelling techniques.

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

thrust and 6.5 seconds lsp increase from extendible RL-10 nozzles
Same as IIA except 4 Castor IVA strap-on SRMs added
Atlas A, B, and C were developmental ICBMs. Atlas D, E, and F configurations were
deployed as operational ICBMs during the 1960s. 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.
