KARLSKOGA, Sweden -- Swedish defense manufacturer Saab has introduced a new anti-tank munition for its Carl-Gustaf weapon system following a live-fire demonstration for international customers. The ammunition, designated HEAT 758, is specifically engineered to neutralize modern heavy armored vehicles.
The development of the HEAT 758 addresses the increasing prevalence of explosive reactive armor (ERA) on the modern battlefield. To counter these defensive systems, the round utilizes a tandem warhead configuration. The initial charge is designed to detonate the reactive plates on the exterior of a target, clearing a path for the secondary main charge to strike the hull. According to technical specifications, the main charge is capable of penetrating up to 700mm of conventional armor.
The munition incorporates Firebolt technology, which enables digital communication between the round and the Carl-Gustaf M4 weapon system. This integration allows the projectile to share data with the Fire Control Device 558, automating certain ballistic calculations to improve accuracy and reduce the technical burden on the operator during engagement.
Saab confirmed that production of the HEAT 758 has already commenced. While the company did not name the specific buyer, it stated that an undisclosed Carl-Gustaf operator has placed an initial order for the new ammunition.
This development restores the tactical viability of shoulder-fired recoilless rifles against frontline main battle tanks. As reactive armor became a standard upgrade for aging vehicle fleets and a baseline feature for new ones, older single-stage munitions lost their effectiveness. By integrating tandem-charge technology and digital fire control into a portable platform, defense forces can maintain a credible anti-armor threat without relying solely on more expensive guided missile systems.
