Which missile has an inert warhead and inert rocket motor, specifically meant for pilot training?

The correct answer is a missile designated as a CATM. This type of missile, which stands for Captive Air Training Missile, is specifically designed to be used in training scenarios for pilots. It features an inert warhead and an inert rocket motor, allowing pilots to practice handling and deploying the missile without the risk and consequences associated with live munitions.

This training system provides a realistic experience for pilots by simulating the weight and handling characteristics of a live missile, thereby enhancing their proficiency and readiness for actual combat situations. The use of inert components further ensures safety and compliance with training protocols. Other options, like DATM or operational missiles such as AGM-88 HARM and AGM-114 Hellfire, do not serve this specific purpose, as they are either variations of training missiles used for design testing or actual combat munitions designed with live warheads and capabilities ideal for targeting.
