Which variant of the AGM-114 uses a thermobaric warhead?

The AGM-114N variant of the Hellfire missile is equipped with a thermobaric warhead. This type of warhead is designed to create a high-temperature, high-pressure explosion and is particularly effective against enclosed spaces and soft targets. Thermobaric weapons utilize atmospheric oxygen to create their explosive force, resulting in a prolonged blast wave and a significant increase in lethality within the target area. This capability makes the AGM-114N especially suited for engaging targets such as bunkers and buildings where conventional warheads might be less effective.

The other variants listed—AGM-114A, AGM-114K, and AGM-114P—are not equipped with thermobaric warheads. The AGM-114A originally featured a high-explosive warhead, while the AGM-114K and AGM-114P incorporate different types of warheads to achieve various tactical objectives, but none utilize the thermobaric design. Therefore, the AGM-114N is the correct choice for this specific question regarding thermobaric capabilities.
