Missiles are powerful weapons that are designed to hit their intended targets accurately and with devastating impact. These weapons come in various sizes and shapes and have different modes of operation. Often, the target of the missile determines the type of missile that is launched. There are several synonyms for the word "missiles", which include rocket, projectile, shell, bomb, and warhead. Rockets are a type of missile that is typically powered by chemical propulsion and used for military or civilian purposes. Projectiles are another synonym for missiles that are propelled through the air or water by energy from an external source. In contrast, bombs are heavy explosive devices that are typically dropped from aircraft. Warheads are the explosive or toxic materials that are carried by missiles.
