A high angle-of-attack projectile or bomb comprises separate compartments that, after launch allow for (a) mixing of the chemi-luminescent materials, (b) heating of the materials in the projectile vessel, (c) pressurization of the projectile vessel, and (d) efficient expulsion of a day marker and heated chemi-luminescent mix upon striking the target. The projectile/bomb allows for the marking of targets. The projectile/bomb does not create unexploded ordnance (UXO) and minimizes use of energetic materials such as reactive chemicals and/or pyrotechnics.
