The present invention is directed to a hard target incendiary projectile that includes a penetrator casing filled with an incendiary and having a rear opening sealed with a closure. When the projectile hits a target and penetrates, a fuze ignites the incendiary. Hot gasses from the burning incendiary increase pressure within the casing so that within milliseconds of the fuze firing, pressure within the casing ejects the closure out of the rear opening with a vigorous pressure pulse that expels burning fragments of incendiary into the interior of the target. The projectile can also carry additional payloads such as chemicals, radioactive materials, and electric/electronic devices that can be ejected from within the casing into the target. The projectile can also be configured so that pressure within the casing opens vents in the closure but does not eject the closure. As the incendiary combusts or reacts within the casing, hot reaction products are vented through the vents into the target. The incendiary can be a non-detonable insensitive solid rocket propellant that burns well at ambient pressure and that can be ignited with a standard fuze having an explosive booster. The casing can be a standard casing that is used in commercially available hard target, high explosive projectiles such as the BLU-109/B or BLU-109A/B currently in service with the U.S. Air Force and the U.S. Navy.

[ What is claimed is:] [1.] A method for attacking a target using an incendiary projectile, the projectile comprising a casing having a rear opening, an incendiary within the casing, a fuze for igniting the incendiary, and a closure occluding the rear opening, the method comprising the sequential steps of:causing the projectile to collide with and penetrate the target;igniting the incendiary using the fuze;expelling the closure from the rear opening using gas pressure developed by incendiary reacting within the projectile; anddynamically ejecting at least a portion of reacting incendiary from the casing through the rear opening using gas pressure from the incendiary reacting within the casing, wherein the ejection disperses the ejected incendiary within the target.
