巡航导弹
How to Understand
巡航导弹 (xún háng dǎo dàn) refers to a type of guided missile that flies at low altitude and maintains a nearly constant speed and altitude during its flight. Unlike ballistic missiles, which follow a high-arcing trajectory, cruise missiles are designed for precision strikes over long distances.
The character 巡 (xún) means 'to patrol' or 'to tour,' 航 (háng) means 'aviation' or 'navigation,' 导 (dǎo) means 'guide' or 'direct,' and 弹 (dàn) means 'shell' or 'missile.' Together, they form a term that describes a missile capable of navigating autonomously over long ranges.
Cruise missiles are widely used in modern warfare for their accuracy and ability to strike specific targets. They are often associated with strategic military capabilities and are a key component of many nations' defense systems. Understanding this term is important for discussions on military technology and international relations.
