OVERVIEW: 125kg General-Purpose Bombs (GPBs) are conventional free-fall unguided munitions designed for use against a wide range of ground targets including troop formations, supply depots, infrastructure, and light fortifications. They offer a balance between blast, fragmentation, and penetration effects for tactical strike missions.

DETAILS: The 125kg class of general-purpose bombs is used by a variety of fixed-wing combat aircraft. These bombs typically feature a steel casing filled with high explosive and may be equipped with nose or tail fuzes (impact or delayed action) depending on mission requirements. Their relatively light weight allows for carriage in large numbers and deployment in precision attack profiles. Some variants may be retrofitted with tail kits or guidance modules to enhance accuracy, though the base design remains an unguided, gravity-dropped munition.
