Which type of bomb has an explosive weight of approximately 50 percent of the total weight?

The general purpose bomb is characterized by its explosive weight being approximately 50 percent of the total weight. This design allows for a balanced structure where the bulk of the weight contributes to the explosive material, making it effective for its intended use. General purpose bombs are versatile and used in various military operations, typically possessing a strong blast effect and the ability to cause significant damage to a broad area or target.

Guided bombs, smart bombs, and incendiary bombs each have different specifications and purposes that do not align with the characteristic of having around 50 percent of their weight as explosives. Guided and smart bombs are often designed with a focus on precision targeting and may include additional components like guidance systems, which can shift the ratio of explosive weight to total weight. Incendiary bombs, on the other hand, are crafted specifically for setting targets ablaze, leading to a different configuration and explosive weight that does not match the general purpose bomb's profile.
