How accurate are precision-guided missiles?
These munitions typically use radio signals from the global positioning system (GPS), laser guidance, and inertial navigation systems (INS)—using gyroscopes—to improve a weapon’s accuracy to reportedly less than 3 meters (approximately 10 feet).
What is JDAM bomb?
The Joint Direct Attack Munition (JDAM) is a guidance kit that converts unguided bombs, or “dumb bombs”, into all-weather precision-guided munitions. The JDAM is not a stand-alone weapon; rather it is a “bolt-on” guidance package that converts unguided gravity bombs into precision-guided munitions (PGMs).
How do GPS guided bombs work?
Put simply, a jammer broadcasts noise such that GPS receivers in their vicinity — which rely on weak signals from distant satellites — are overwhelmed and lose the actual GPS signal. If a precision-guided bomb, a minute away from hitting its target, loses the lock, the results could be disastrous.
How much does a JDAM cost?
Joint Direct Attack Munition

What is the difference between the two types of laser-guided bombs?
There are two basic families of laser-guided bombs in American (and American-sphere) service: the Paveway II and the Paveway III. The Paveway III guidance system is more aerodynamically efficient and so has a longer range, however it is more expensive.
How many rounds does it take to hit a target?
One Excalibur projectile can accurately hit an intended target that would require the use of between 10 and 50 unguided artillery rounds. Initial combat experience with Excalibur in Iraq in the summer of 2007 was highly successful, with 92\% of rounds falling within 4 metres (13 ft) of the target.
How do you extend the range of a missile?
The extended range is achieved through the use of folding glide fins, which allow the projectile to glide from the top of a ballistic arc towards the target. The munition was co-developed by United States-based Raytheon Missile Systems (guidance system) and the Swedish BAE Systems Bofors (body, base, ballistics and payload).
What was the first successful electro optical guided munition?
The first successful electro optical guided munition was the AGM-62 Walleye during the Vietnam war. It was a family of large glide bombs which could automatically track targets using contrast differences in the video feed.
