Which General purpose (GP) bombs weigh 500 pounds?

The 500-pound General Purpose bombs include the MK-82 and BLU-111. Both of these bombs are designed for a variety of tactical operations, providing versatility in combat scenarios. The MK-82 is a conventional bomb that has been widely used since its introduction, and the BLU-111, essentially a modern variant, retains the same weight and dimensions while often utilizing more advanced materials and designs for enhanced performance and safety in certain environments.

When considering the other options, the MK-83 and MK-84 are heavier, weighing 1,000 pounds and 2,000 pounds respectively. The GBU-12 and GBU-10 are laser-guided bombs that also do not fit the 500-pound classification; they typically refer to modified versions of the MK-82 and MK-84. Similarly, the MK-77 and BLU-109 are specialized munitions that exceed the 500-pound weight limit, highlighting that the specific designation of 500-pound bombs is distinctly held by the MK-82 and BLU-111. This clarifies why the selection of the MK-82 and BLU-111 is the correct identification for the 500-pound GP bombs.
