This report describes the development of an emplacement-retrieve mechanism which would be fast acting, lightweight, effective in all soils, and be simple to operate and maintain. The fact that the site chosen for erection is dictated by the tactical situation rather than soil conditions makes it necessary that the emplacement retrieve device be capable of operating where conventional techniques fail. This program was concerned with the selection of an approach which had the greatest potential to satisfy system requirements and then developing the item to demonstrate the feasibility of the approach selected. A wide range of devices such as explosive shaped charges, rocket devices, recoilless launchers, impact hammers, ballistic tools and vibratory drivers were evaluated and a ballistic hammer selected as having the greatest potential for development. A design for this device was evolved, based upon analytical considerations and results of tests with a firing mockup. A model was constructed. The performance of a ballistic hammer was evaluated in a series of tests.
