Weather Documentation at Kwajalein Missile Range


Book Description

A WB-57F weather reconnaissance aircraft and a high-power radar (ALCOR) were used to document weather at Kwajalein Missile Range. Simultaneous measurements of cloud-reflectivity (Z) by radar, and water content (M) by aircraft were used to interpret measurements of reflectivity along the reentry trajectories close to the time of reentry. Techniques of obtaining and processing the data are described, and the results of the analysis for one mission are presented. These techniques permit the specification of the water content along the trajectory within a factor of 2, or plus or minus 3 dB. Observations from this case and from other days show the variability of the Z-M relation with altitude and cloud type. (Author).

Hydrometeor Data and Analytical-theoretical Investigations Pertaining to the SAMS Rain Erosion Program of the 1972-73 Season at Wallops Island, Virginia


Book Description

Radar, aircraft, and surface measurement information is presented concerning the liquid-water-content values and size distribution properties of the hydrometeors that existed along the trajectory paths of the four SAMS missiles that were fired into Wallops storm during the 1972-73 season.







Snow Characterization Instruments


Book Description

This report details the design, fabrication, and operation of three new instruments that were developed at AFGL to define some of the physical characteristics of naturally falling snow. Two are devices for the measurement of fall velocity and high-resolution snow rate. The other was conceived for the documentation of the ice-crystal composition of the prevailing snow. Problems that surfaced during the first year of operation are discussed along with the plans to correct the deficiencies. Examples of the data supplied by these instruments are shown.

Minuteman


Book Description

In Minuteman: A Technical History of the Missile That Defined American Nuclear Warfare, David K. Stumpf demystifies the intercontinental ballistic missile program that was conceived at the end of the Eisenhower administration as a key component of the US nuclear strategy of massive retaliation. Although its nuclear warhead may have lacked power relative to that of the Titan II, the Minuteman more than made up for this in terms of numbers and readiness to launch—making it the ultimate ICBM. Minuteman offers a fascinating look at the technological breakthroughs necessary to field this weapon system that has served as a powerful component of the strategic nuclear triad for more than half a century. With exacting detail, Stumpf examines the construction of launch and launch control facilities; innovations in solid propellant, lightweight inertial guidance systems, and lightweight reentry vehicle development; and key flight tests and operational flight programs—all while situating the Minuteman program in the context of world events. In doing so, the author reveals how the historic missile has adapted to changing defense strategies—from counterforce to mutually assured destruction to sufficiency.
