General Purpose bombs are characterized by their explosive weight being approximately what fraction of the total weight?

• A. 25%
• B. 50%
• C. 75%
• D. 100%

Answer: (B)

The main idea is the ratio of explosive fill to the total bomb weight. General Purpose bombs are designed so that about half of their total weight is the explosive payload, with the remaining half being the steel casing and other components like the fuse and inert hardware. This balance provides effective blast and fragmentation while keeping the bomb structurally strong, aerodynamically stable, and easier to handle and release.

Choosing half as the typical fraction reflects the need for a solid casing to shape the explosion and to produce fragmentation, without making the bomb too light or too fragile. If the explosive portion were only a quarter, the blast and fragmentation would be insufficient for wide-area effects; if it were three-quarters or all explosive, the bomb would lack the necessary casing mass for stability and would be impractical to manufacture and deliver safely.
