OVERVIEW: The 120kg m/61 High-Explosive General Purpose Bomb (GPB) is an unguided aerial bomb developed by Sweden for use in tactical strike roles. It is intended for use against light infrastructure, troop concentrations, and soft targets through blast and fragmentation.

DETAILS: The m/61 HE GPB is a Swedish-manufactured general-purpose bomb featuring a forged steel casing filled with high explosive, typically TNT or similar compounds. Weighing approximately 120 kg, it was designed for use by Swedish Air Force aircraft such as the Saab 32 Lansen and Saab 35 Draken. The bomb is fitted with fixed tail fins for stabilization and may be equipped with contact or delayed-action fuzes, depending on mission requirements. Its explosive yield is optimized for maximum effect against personnel, unarmored vehicles, and structures, making it versatile for both close air support and interdiction missions. The m/61 was intended to fulfill NATO-standard ordnance roles within Sweden's non-aligned doctrine during the Cold War.
