OVERVIEW: The 600kg m/50 High-Explosive General Purpose Bomb (GPB) is a Swedish unguided aerial munition developed for heavy strike missions. It is designed to destroy fortified targets, infrastructure, and area troop concentrations through extensive blast and fragmentation effects.

DETAILS: The m/50 600kg bomb is part of Sweden’s Cold War-era air ordnance inventory, featuring a thick steel casing filled with a large high-explosive charge—typically TNT or a similar compound. Developed in the early 1950s, it was used by Swedish strike aircraft such as the Saab 32 Lansen and later the Saab 37 Viggen in heavy-attack configurations. It is equipped with fixed tail fins for ballistic stability and supports both impact and delayed-action fuzes for flexible employment against above-ground or buried targets. Its significant weight gives it deep penetration and wide-area lethality, making it suitable for attacking hardened facilities, runways, and troop concentrations. Though unguided, it served as a strategic tool in Sweden's doctrine of national defense and deterrence.
