Which type of bomb has a capacity of 60000lbs?

The semi-trailer or tractor trailer bomb is recognized for its substantial capacity, making it capable of holding up to 60,000 pounds of explosive material. This type of bomb typically involves using large vehicles that can transport a significant amount of explosives, thereby maximizing the potential impact of the detonation. Such vehicles are often used in high-profile attacks due to their ability to carry a considerable payload, resulting in a devastating explosion when detonated.

In contrast, the other options have much smaller capacities. Car bombs and small delivery truck bombs have limited space for explosives compared to a semi-trailer. Briefcase bombs are designed for portability and are only capable of holding a small amount of explosive material, making them unsuitable for such high explosive capacities.
