Activities and Results of IRMP 59/60 in Operation Big Army.
Abstract
Data were collected and evaluated on missiles fired by the Russians on 20 and 31 Jan 1960 intoA DESIGNATED TARGET AREA OF THE Pacific Ocean. The data were collected by 4 interservice radiation measurement program groups with various types of photographic and radiometric equipment on board a KC-135 plane. Preliminary conclusions were reached on the first missile: (1) the range between KC-135 and impact was about 220 naut-mi; (2) the radiative intensities of the re-entering afterbody in the PbS region were about 1 million w/steradian/micron; (3) the visible nose cone intensities lie in the order of 100,000 w/steradian; (4) the nose cone temperature was assumed to be about 3000 K; (5) the re-entry angle was 18 to 21 degrees; (6) the nose cone is a highperformance ablative-type; (7) the radiative energy would be consistent with the radiation from a hemisphere with a diameter of 2 m; (8) the re-entering body could have weighed about 3500 lbs; (9) only aluminum oxide was definitely established in the afterbody; and (10) no indication was observed of a multiple warhead or decoys.
