Armored vehicles now roll out with thick layers of explosive reactive armor that detonate on contact and blunt older anti-tank munitions. Saab created the HEAT 758 to cut straight through that problem. The round slides into the familiar 84-millimeter Carl-Gustaf recoilless rifle and carries two shaped charges arranged in sequence. The lead charge strikes first and clears a path by disrupting the reactive plates. Moments later the main charge jets forward and bores into the vehicle’s base armor.
Engineers optimized the design so that the entire package can defeat up to 700 millimeters of armor. That depth is comparable to the heaviest tanks currently in service. The range extends to 600 meters while keeping the round around the same size and weight as the previous HEAT 751. Soldiers bear no additional burden while gaining increased distance and power with each shot.

Firebolt technology is at the heart of the advancement. The round chambers in the Carl-Gustaf M4 communicate data with the launcher and the connected fire control unit. The aiming system receives data on propellant temperature, ammunition type, and ambient variables directly. Gunners avoid the archaic manual dials and settings. The weapon handles the computations, resulting in a cleaner ballistic solution. Accuracy improves as fewer variables slip through under stress.
Years of battlefield reports served as the basis for development. Ukrainian crews have already proved the HEAT 751’s effectiveness against Russian T-90 tanks fitted with Kontakt-5 and Relikt armor. Saab examined probable outcomes, ran tens of thousands of numerical simulations, and meticulously refined every aspect of the new round. Carbon-composite sleeves and a titanium liner keep the ammunition light and durable inside the barrel. The muzzle velocity is 255 meters per second, which is enough to cover the extra range without sacrificing punch.
Live demonstrations in Karlskoga, Sweden, ended only a few days ago. Customers saw the round perform exactly as expected against representative targets. An anonymous buyer has already placed an order, and production lines are moving. The date corresponds to a significant shift in how modern armies think about spread firepower. A single squad with a Carl-Gustaf and these bullets can pose a danger to vehicles that previously required coordinated heavy weapons.
