What is explosive reactive armor made of?

An element of explosive reactive armour is made out of a sheet or slab of high explosive sandwiched between two plates, typically metal, called the reactive or dynamic elements. On attack by a penetrating weapon, the explosive detonates, forcibly driving the metal plates apart to damage the penetrator.

How does non explosive reactive armor work?

NERA (Non-Explosive Reactive Armor) consist of an dense elastomer interlayer compressed between two metal plates, or flyer plates. On impact the elastic material will compress to the point of maximum compression, until expanding again and bouncing back, forcing the plates to bulge.

What will penetrate Level 4 armor?

That being said, in general, it will take at least a tungsten carbide (NOT just hardened tool steel or similar) AP 7.62×51 round (M993 or similar) within 300-400 meters to reliably penetrate a level 4 ceramic plates with just a single round.

What is explosive reactive armor (ERA)?

Explosive reactive armour (ERA) is widely used on modern armoured vehicles to protect them against attack from chemical energy warheads. Originally the ERA was developed to defeat shaped charge warheads [ 1

What type of armour is most effective against shaped charges?

It is most effective in protecting against shaped charges and specially hardened kinetic energy penetrators. The most common type is explosive reactive armour (ERA), but variants include self-limiting explosive reactive armour (SLERA), non-energetic reactive armour (NERA), non-explosive reactive armour (NxRA), and electric reactive armour.

How does plate tectonics affect reactive armor?

As the plates bulge, the point of jet impact shifts with the plate bulging, increasing the effective thickness of the armour. This is almost the same as the second mechanism that explosive reactive armour uses, but it uses energy from the shaped charge jet rather than from explosives.

What are the different types of reactive armour?

The most common type is explosive reactive armour (ERA), but variants include self-limiting explosive reactive armour (SLERA), non-energetic reactive armour (NERA), non-explosive reactive armour (NxRA), and electric reactive armour.
