In order to improve damage effect of standard high explosive fragment projectile, high fragmentation rate of steel was used to replace common D60 steel in application of bomb body material. The theoretical contrast calculation results between the steel performed fragments projectile and standard bomb shows that lethality power of the steel performed fragments projectile is improved 70% than that of standard bomb. The result of the static detonation shows that lethality power of the steel performed fragments projectile was improved 73% than that of standard bomb. The damage capacity is strong to 8mm armor plate. The theoretical calculations and static burst test results are consistent. The damage efficiency of performed fragments projectile in high fragmentation rate is stronger than that of standard bomb.
