The AGM-154 Joint Standoff Weapon (JSOW) is a glide bomb that resulted from a joint venture between the United States Navy and Air Force to deploy a standardized medium range precision guided weapon, especially for engagement of defended targets from outside the range of standard anti-aircraft defenses, thereby increasing aircraft survivability and minimizing friendly losses. It is intended to be used against soft targets such as parked aircraft, trucks, armored personnel carriers (APCs), and surface-to-air missile sites (SAMs). Prior to launch, it is given a destination through either a predesignated waypoint or a point marked through a targeting pod. It glides, using two wings that pop out for added lift, to the marked destination and dispenses submunitions in a short, roughly linear pattern. The designation of the Joint Standoff Weapon as an "air-to-ground missile" is a misnomer, as it is an unpowered bomb with guidance avionics, similar to the older GBU-15.

A glide bomb or stand-off bomb is a standoff weapon with flight control surfaces to give it a flatter, gliding flight path than that of a conventional bomb without such surfaces. This allows it to be released at a distance from the target rather than right over it, allowing a successful attack without exposing the launching aircraft to anti-aircraft defenses near the target. Glide bombs can accurately deliver warheads in a manner comparable to cruise missiles at a fraction of the cost—sometimes by installing flight control kits on simple unguided bombs—and they are very difficult for surface-to-air missiles to intercept due to their tiny radar signatures and short flight times. The only effective countermeasure in most cases is to shoot down enemy aircraft before they approach within launching range, making glide bombs very potent weapons where wartime exigencies prevent this.
