The advanced Kontakt-5 explosive reactive armour on this T-90S is arranged in pairs of plates, giving the turret its prominent triangular profile.. An element of explosive reactive armour (ERA) is made of either a sheet or slab of high explosive sandwiched between two metal plates, or multiple "banana shaped" rods filled with high explosive which are referred to as shaped charges.
An RPG-29 and its PG-29V rocket with a tandem-charge warhead The self-guided FGM-148 Javelin missile has a tandem-charge warhead. Tandem charges are effective against reactive armour, which is designed to protect an armoured vehicle (mostly tanks) against anti-tank munitions. [1]
The advanced Kontakt-5 explosive reactive armour on this Indian Army T-90S is arranged in pairs of plates with a triangular profile. Kontakt-5 is a type of second-generation [1] explosive reactive armour (ERA) originating in the Soviet Union. Due to the shortcomings of Kontakt-1, NII Stali developed a new type of reactive armor, Kontakt-5, so ...
The first, smaller warhead initiates the reactive armor, while the second (or other), larger warhead penetrates the armor below. This approach requires highly sophisticated fuzing electronics to set off the two warheads the correct time apart, and also special barriers between the warheads to stop unwanted interactions; this makes them cost ...
The tandem warhead is fitted with two shaped charges: a precursor warhead to detonate any explosive reactive armor and a primary warhead to penetrate base armor. In what is known as a "soft launch arrangement," the missile is ejected from the launcher to a safe distance from the operator before the main rocket motors ignite. [17]
With a tandem-charge, an initial small charge detonates any reactive armor. If explosive reactive armor (ERA) or cage armor is absent, this charge strikes the main armor. Behind the primary charge, a much larger secondary shaped charge bursts at the rear of the initial warhead and projects a thin, high-speed-jet of metal into the armour ...
Kontakt-1 (Russian: Контакт-1; GRAU indice: 4S20) is an explosive reactive armour (ERA) created in 1982 by Soviet NII Stali to protect tanks from shaped charges. The first tank with Kontakt-1 put into service was T-64BV in 1985. The system is still widely used by different countries within T-55, T-62, T-64, T-72, T-80 tank families among ...
Tandem-charge missiles attempt to defeat explosive reactive armour (ERA): the small initial charge sets off the ERA while the follow-up main charge attempts to penetrate the main armor. Top-attack weapons such as the US Javelin , the Swedish Bill and the Indian Nag and MPATGM are designed to strike vehicles from above, where their armor is ...
