Abstract
Numerical simulations were undertaken to investigate the possibility of effectiveness of using blast or fragment impacts as hard kill countermeasures against kinetic energy threats (tungsten rods at high velocity) and chemical energy threats (shaped charges). The results indicate that medium calibre (APFSDS-like) projectiles can be deflected or disrupted effectively by either blast or small fragment impact. Long rods (again APFSDS-like) are much harder to disrupt and the various approaches surveyed did not work. For shaped charge jets, premature detonation due to fragment impact is possible but there remains a non-negligible off-axis residual jet that must be stopped.
