Which statement best describes the primary difference between BLU-series and MK-series General Purpose bombs?

• A. MK-series bombs are Insensitive Munitions (IM) with less sensitive explosive fillers.
• B. BLU-series bombs are Insensitive Munitions (IM) with less sensitive explosive fillers.
• C. BLU-series bombs are more sensitive than MK-series bombs.
• D. MK-series bombs are Insensitive Munitions (IM) with more sensitive fillers.

Answer: (B)

Insensitive Munition (IM) guidelines drive a key safety difference between these GP bomb families. BLU-series bombs are designed as IM devices, using less sensitive explosive fillers to reduce the chance of unintended detonation from heat, shock, or impact. This makes them safer to handle, store, and transport compared with MK-series bombs, which use conventional, more sensitive fillers and are not IM. So the statement that BLU-series bombs are IM with less sensitive fillers best captures the primary difference. The other options would imply MK-series are IM or that BLU bombs are more sensitive, which isn’t correct given the IM safety emphasis.
