The US Office of Naval Research successfully tested a new explosive substance that has five times the explosive power of materials available today. The revolutionary new High-Density Reactive Material (HDRM) is a mix of polymers and metals that is reported to have the density of mild steel but the strength of aluminum.
Traditional military projectiles, like missiles and shells, are built with a steel casing that houses explosive materials that explode on impact. The new method replaces the steel casing with HDRM, which combines with warhead explosives and only explodes once the target has been penetrated, explains Clifford Bedford, a scientist working for the Office of Naval Research (ONR) on the development of the new substance.
On impact, HDRM reacts with explosives and creates a chemical explosion. "In the case of a steel missile you explosively launch it, it goes through the target and all the kinetic energy is dissipated into the target," Bedford said in an ONR statement.
"With the reactive material missile, it disintegrates within the target and liberates chemical energy, and this chemical and kinetic energy combined gives you the enhanced effect."
Reduced Collateral Damage
In addition to augmented destructive capability, the ONR believes it could also lower civilian casualties in densely populated areas. Because HDRM reacts and is consumed once it hits the target, there is potential to control the explosion. “If this can be focused, which I know we can do, we can really reduce the collateral damage for these systems," said Bedford.
The HDRM could eventually be introduced into grenades and bullets for high-caliber machine guns and larger weapons, but researchers say it is likely to be used first in anti-missile warfare.
Currently anti-missile systems require three or four shots to be fired because the high amount of steel fragments in traditional warhead explosions make it difficult to determine if an incoming projectile has been destroyed.
HDRM’s increased explosive power would raise the probability of taking down incoming munitions faster and with fewer missiles. "Hopefully, with the reactive warhead, we fire once, look and can determine a catastrophic kill. We still have the option for a second fire. But it saves a great deal of cost if you can take out the target with one missile versus three,” said Dr Bedford.
More HDRM tests have been scheduled for September. But five times the explosive power costs up to four times as much to develop, which means budget may also be a factor with the eventual introduction of the new technology.
