Saab has developed a brand new anti-tank spherical that is designed to tackle the trendy high-tech armor of the twenty first century. Constructed for Saab’s Carl-Gustaf 84-mm (3.31-in) recoilless rifle system, the HEAT 758 munition may even defeat fashionable reactive armor.
Individuals whose data of armor and the weapons to penetrate it come from standard leisure are inclined to underestimate the complicated battle between offense and protection that has performed out over the previous century – particularly on the subject of growing handheld weapons that may tackle predominant battle tanks. It is much more than giant, fiery explosions hitting slabs of recalcitrant steel.
When the primary tanks emerged in the course of the First World Battle, they have been protected by riveted plates of delicate metal that could possibly be penetrated by a high-powered rifle. By the Second World Battle, the metal alloys had improved in composition, steel fabrication strategies made armor extra homogeneous, and the thickness was elevated to create a lot harder plating. This was improved much more by studying the right way to slope the armor to deflect incoming shells and dissipate the affect.

This was countered by new anti-armored weapons just like the German Panzerfaust and Panzerschreck, the American. Bazooka, and the British PIAT, all of which used formed fees to pay attention the explosive drive of the warhead right into a jet of white-hot steel that burned by means of thick plating. This counter was counter-countered then counter-counter-countered as composite armors have been invented that consisted of metal, ceramics, and composites, which then later to take care of high-velocity darts fabricated from depleted uranium.
One notably efficient advance was Explosive Reactive Armor (ERA), the place the tank’s hull is roofed with metal packing containers full of excessive explosives. These packing containers are designed to detonate if hit by a formed cost, producing a counter-explosion that disrupts and deflects the incoming projectile or blast.
This reactive armor has grow to be more and more subtle, so Saab and different protection contractors have needed to grow to be more and more subtle as effectively.

Demonstrated on Might 7 in Karlskoga, Sweden , the HEAT 758 is that newest spherical made for the Chilly Battle-vintage Carl-Gustaf household of recoilless rifles. It is particularly engineered to tackle heavy armored autos protected by fashionable reactive armor, together with the Kontakt-1, Kontakt-5, and Relikt techniques.
The HEAT 758 is what is named a tandem-charge anti-tank munition consisting of two levels. Earlier variations of such tandem-charge rounds defeat the reactive armor by having the primary cost hit the explosive field, setting it off. This permits the second stage to penetrate to the now unprotected metal plate and blast by means of it with a formed cost.
It is a sound idea, however that first explosion may be counterproductive because it interferes with the secondary predominant cost jet. The HEAT 758 tries to beat this with a Non-Initiating Precursor (NIP) within the second stage that takes benefit of a weak point of reactive armor.
Opposite to standard perception, explosives aren’t straightforward to set off. Dynamite will not go BOOM for those who drop it, you’ll be able to toss gelignite prefer it’s putty, and I’ve really seen TNT burn in a camp hearth. To make any of those explode, you want a series of more and more delicate explosives added to the primary cost main again to a detonator to set off the massive present.
That is necessary on the subject of reactive armor as a result of having it sitting on a tank means it must be delicate sufficient to blow up if hit by hostile hearth, however not if the car occurs to rear-end a Honda, which might make folks speak. What the HEAT 758 does is to use the candy spot by hitting the reactive armor onerous sufficient to penetrate it and open up a path for the formed cost, however not onerous sufficient to detonate it.
In accordance with Saab, that is the results of utilizing AI to run 50,000 digital simulations of how the HEAT 758 hits its goal. As well as, the spherical makes use of Firebolt know-how, which employs a digital communication hyperlink between the munition, the Carl-Gustaf M4 launcher, and the Fireplace Management System 558 to retrieve knowledge concerning the particular ammunition kind and propellant temperature to calculate the optimum ballistic trajectory for optimum impact.

The HEAT 758 can penetrate Rolled Homogeneous Armor as much as 100 mm thick at an efficient vary of as much as 700 m (766 yd) with a muzzle velocity of 255 m/s (570 mph). Every spherical weighs about 7 kg (16 lb) and is lower than 1 m (39 in) lengthy, with a sleeve fabricated from carbon composites and a titanium barrel liner.
In accordance with the corporate, the HEAT 758 is already below manufacturing for an undisclosed buyer.
“This spherical is our response to developments on the battlefield the place reactive explosive armor has grow to be a serious drawback for normal munitions attempting to defeat armored autos,” mentioned Michael Höglund, head of Saab’s enterprise unit Floor Fight. “HEAT 758 is an instance of how Saab continues to generate ever extra succesful merchandise whereas lowering the armored car menace to the operator.”
