"Warfare could be transformed by hypersonic missiles able to search for, identify and lock on to targets based on heat signature.”

"Have you ever seen a heat seeking missile in-flight as it flies toward its target? The nose of the missile shifts back-and-forth, back-and-forth, back-and-forth; slightly moving to the right, recalibrating to move slightly to the left, recalibrating to move slightly back to the right, recalibrating to move slightly back to the left. It continues this back-and-forth, this right and left dance until it finally locks in on the target, and strikes."

"These missiles consist of a seeker head mounted at the tip of the missile, you can compare it to the ‘Nose’ in our previous analogy. The seeker head is technically a suite of extremely sensitive and expensive sensors that pick up on infrared light.
The missile in itself cannot really ‘See’ its target – it can’t differentiate between a hot air balloon and an F-35, it just sees the track that the target it has locked on makes."

"It is estimated that 90 percent of all the aircraft lost by the US Air Force since the 1980s have been shot down by heat-seeking missiles, and stealth fighters such as the F-22 may be targeted because their coating materials easily heat up in flight. A Chinese military researcher told an academic conference in 2020 that an F-22 could be destroyed in a matter of seconds by a ground-to-air hypersonic missile"
