Atlas International Group Deliver And Supply 100mm Round With A High Explosive Shell.


The T-12 and MT-12 smooth bore anti-tank guns have a long and storied history in modern warfare. But even a legendary weapon such as this is only so much heavy metal when it is not paired with the right ammunition. If you need serious anti-tank stopping power, you need an ammunition supply that will really turn up the HEAT.


HEAT or High Explosive Anti-Tank warheads can provide the stopping power that’s necessary for heavily armored enemy tanks. These rounds use the Munroe effect to penetrate even the thickest armor. Let’s take a look at what makes these powerful warheads so effective as well as detailing some common military applications for them.


The Munroe Effect


The Munroe effect (also known as the Neumann effect) is at the heart of the HEAT round’s stopping power and superior “fist to finger” armor penetration. It is named after Charles E. Munroe, who discovered it in 1888 while working as a civilian chemist at a U.S. Naval Torpedo Station. The principle maximizes the explosive power of the payload while allowing for a relatively light round. These rounds are designed to concentrate blast energy to a fixed point using a conical liner within the shell’s nose containing an air filled cavity. Beneath this is the detonator attached to the explosive payload with a Piezo-electric trigger within the nose. These elements all combine to create a focused force capable of penetrating steel armor many times thicker than the charge depth.


Despite the popular acronym HEAT, the shell relies on kinetic energy for its devastating stopping power rather than burning or melting through steel armor.


Potential applications


The 100mm round with a high explosive shell is a traditionally anti-tank ammunition, its applications do not stop there. These rounds are sometimes paired with the KS-19 anti-aircraft gun. Its relatively light weight (16.74kg per shell) make it a devastating air defense weapon. This ammunition has also historically been used for;


  • Demolishing enemy encampments.
  • Penetrating enemy bunkers.
  • Disabling heavily armored enemy artillery such as mortars.
  • Disabling enemy field equipment.
  • Disabling enemy manpower both in the open and in shelters.
  • Breaching defensive wirings.
  • Facilitating safe passage through enemy minefields.


Over the years they have also had non military applications including large scale demolition, boring holes, cutting through rock and ice and clearing log jams.


As you can see, these rounds are both powerful, agile and precise yet have a robust and diverse array of applications.


Ballistic characteristics


These 100mm rounds are manufactured by Dunarit and use a B-429 fuse. They have a muzzle velocity of 700 meters per second.


100mm rounds with a high explosive shell have been a mainstay of modern warfare for decades for a reason. They combine prodigious power with direct focus and enormous tactical versatility. Whether you seek to disable your enemy’s armored vehicles, devastate their field equipment or fire devices or deliver targeted anti-personnel stopping power, these rounds will go a long way towards securing your victory.
