Abstract : In order to answer the question of the Royal Netherlands Navy, about the effectiveness of 120 mm mortargrenades, the Prins Maurits Laboratory (PML) started an investigation. As a part of that investigation the Ballistics Research Laboratory of PML carried out 15 experimental tests. The purpose of these tests was to determine the fragmentation parameters of two types of 120 nun shells: the cast iron 104C2 and the steel 104C5. PML-TNO developed a method for this named STAFDIP 1. With this method it is possible to detonate the shell statically and determine the fragment mass and velocity. In the same experiment the perforation capacity against several target materials can be obtained. The results show a much larger amount of fragments produced by the cast iron shell, while the steel one has bigger fragments in a smaller amount. This causes the steel shell to have a larger effect on the thicker target plates (10 mm St37 or more). But because of the large amount of small fragments the cast iron shell has more effect against the thinner targets.... Effectiveness, Tests, Fragmentation.
