What is the launch weight of a GP bomb?

The correct answer reflects the typical launch weight of a GP (General Purpose) bomb, specifically referring to the most commonly used variants. The 505 kg weight signifies a standard configuration for a certain class of GP bombs employed in military operations, optimal for delivering destructive payloads while maintaining a balance between explosive power and aircraft carry capacity.

This weight also aligns with the characteristics and requirements of modern aerial munitions, which are designed to be effective against a variety of target types while being manageable for aircraft in terms of handling and deployment. Understanding the specifications of GP bombs and their weights is crucial for effective mission planning, aircraft load calculations, and adherence to operational guidelines, as it directly impacts the aircraft's performance and the effectiveness of air-to-ground strike capabilities.

Other weights listed in the options may refer to different types or configurations of munitions but do not represent the standard launch weight for the commonly utilized GP bomb in the military context.
