OVERVIEW: 500kg General-Purpose Bomb (GPB) is a standard unguided aerial munition designed to destroy a wide range of ground targets through blast and fragmentation effects. It balances payload weight and explosive power for maximum battlefield utility in tactical and strategic bombing missions.

DETAILS: This bomb typically features a steel casing filled with high-explosive material and employs impact or delay fuzes for flexible detonation timing. Effective against enemy troop concentrations, buildings, light vehicles, and infrastructure. It is typically released from fast jets or multirole aircraft and is often used in both high- and low-altitude bombing profiles. Its weight class allows a significant destructive footprint while still enabling aircraft to carry multiple munitions per sortie.
