The Pugliese system placed a large cylinder inside a fluid-filled protective space so that an underwater explosion could be absorbed before reaching the inner hull. Comparable British experiments used crush cylinders inside feed-water tanks. Both approaches separated an outer impact zone from the protected structure and managed energy through controlled deformation and dissipation. The same principles later appeared in civilian vehicle crumple zones, providing a compact example of military engineering ideas entering everyday safety design.

From torpedo defense to civilian crumple zones
Systems designed to absorb underwater blast energy illustrate principles that later appeared in automobile crumple-zone engineering.
