and AGM-84 Harpoonanti-ship missiles. Many air-to-surface missiles can be used against both ships and land targets, although some must be modified to perform a different role; for example, the AGM-84E Standoff Land Attack Missile is a land-attack version of the Harpoon.
A major advantage of air-to-surface missiles for ground attack by aircraft is the standoff distance they provide: missiles can be launched from a distance without coming within range of the target's air defences. Most air-to-surface missiles are

There have been examples of air-launched ballistic missiles ( Air Launched ICBM, GAM-87 Skybolt), but they are rare. Sometimes air-to-surface missiles are divided into the categories of ''tactical'' and ''strategic''. Typically missiles with chemical explosive or small nuclear warheads are classed as tactical, and large nuclear warheads as strategic.
