Abstract Effectiveness of a honeycomb shield assembled of gas-filled containments is discussed. A numerical tool is developed aimed at investigating hypervelocity impact of a spherical projectile on thin-walled metallic containment filled in with gas or fluid. Variation of gas density inside the containment essentially affects perforation scenario and successive fragmentation of the projectile, while variation of gas properties – adiabatic index – does not affect fragmentation, but has a strong influence on shock wave generated by fragments in the containment.
