Significance: Eleven rammed earth revetments were constructed during World War II to provide shelter and cover for aircraft in case of an attack from the Pacific. The revetments are strongly associated with the war effort and are among only a few remaining World War II era buildings and structures at Edwards AFB. Two different designs were constructed, one for bombers and another for pursuit aircraft. The method of construction employed, utilizing layers of earth and aggregate tamped into a form, is unusual and may be unique. Although six of the revetments are extant, only two revetments were found to be eligible for listing in the National Register of Historic Places. AR-8, which retains the highest degree of integrity of the bomber revetments, and AR-9, which is the only extant pursuit aircraft revetment, are significant under Criteria A, C, and D.
