Which statement about IR guided missiles is true?

The statement that "They do not produce emissions during targeting" is accurate because infrared (IR) guided missiles rely on detecting the heat signatures of targets, such as engines or other heat-producing components. This targeting process uses passive detection methods, meaning that the missile does not emit any signals during the targeting phase, thus maintaining a lower profile and reducing the likelihood of detection by enemy radar systems.

Infrared guidance systems are especially effective in engaging targets without revealing their position or compromising stealth. This passive approach is a critical advantage in a combat environment, allowing for greater tactical flexibility. Other types of guided systems, such as those relying on radar, would typically generate emissions that could potentially disclose their location to adversaries.
