What type of warhead does the GBU-39 utilize?

The GBU-39 utilizes a penetrating blast fragmentation warhead, which is specifically designed for precision strikes against fortified or hardened targets. This type of warhead combines the effects of both penetrating capabilities and blast fragmentation to maximize damage upon impact.

The design allows the warhead to penetrate certain surface structures before detonating, thereby increasing its effectiveness against targets such as bunkers and shelters. The blast fragmentation aspect enables the warhead to produce shrapnel upon detonation, which can damage surrounding equipment and personnel, expanding its overall lethality beyond just the direct impact point.

This characteristic aligns with the need for precision-guided munitions that can engage targets with minimum collateral damage, making the GBU-39 highly effective in a combat environment where accuracy is paramount.
