Defensive missiles are weapons that are designed to intercept and destroy incoming enemy missiles or aircraft. These types of missiles come in many different shapes and sizes, and are often referred to by a variety of different names. Some common synonyms for defensive missile include interceptor missile, anti-aircraft missile, surface-to-air missile, and air defense missile. These missiles are typically used to protect important military targets such as airfields, naval vessels, and strategic installations. While defensive missiles are an important part of modern military strategy, they are also a controversial weapon, as they can be seen as destabilizing and threatening to other countries and regions.
