Abstract:

An engineering test of the overhead cover for foxholes was conducted at Aberdeen Proving Ground from 14 April to 23 June 1969. The test was divided into three phases an overpressure evaluation, an emplacement life test, and an artillery air burst test. The overpressure evaluation was based on results obtained with prototype covers in Operation Prairie Flat conducted by the Canadian Defense Research Board in August 1968. Forty covers were used in the emplacement life test. Thirty covers were emplaced for 48 or - 2 hours and ten for 168 or - 2 hours. Emplacement was in accordance with the instruction sheet provided with each item. After the emplacement life test, each cover installation and ten timber installations were subjected to the artillery air burst test. A 105-mm projectile was statically detonated over each timber installation and each of 30 cover installations. A 155-mm projectile was statically detonated over each of ten cover nstallations. The projectile heights varied between 2.5 and 13.0 feet.
