What is the meaning of precision guided munitions?
The Department of Defense (DOD) defines a precision- guided munition (PGM) as a “guided weapon intended to destroy a point target and minimize collateral damage.” This includes air- and ship-launched missiles, multiple launched rockets, and guided bombs.
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).
How do precision guided missiles work?
By definition, a Precision-Guided Munition (PGM) is an explosive missile, rocket, or bomb that is guided by a “seeker” control system using a laser guidance beam, a global positioning system (GPS), and/or an integrated inertial navigation system for highly-accurate acquisition of military targets.
How accurate are laser-guided missiles?
A laser-guided bomb (LGB) is a guided bomb that uses semi-active laser guidance to strike a designated target with greater accuracy than an unguided bomb. Unguided bombs had an accuracy rate of just 5.5% per mission, which usually included large numbers of the munitions.
What are smart munitions?
A precision-guided munition (PGM, smart weapon, smart munition, smart bomb) is a guided munition intended to precisely hit a specific target, to minimize collateral damage and increase lethality against intended targets.
What does munitions mean in English?
noun. Usually munitions. materials used in war, especially weapons and ammunition. material or equipment for carrying on any undertaking.
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).
What is tercom system?
Terrain Contour Matching, or TERCOM, is a navigation system used primarily by cruise missiles. It uses a pre-recorded contour map of the terrain that is compared with measurements made during flight by an on-board radar altimeter.

What are precision‐guided munitions (PGMs)?
Precision‐Guided Munitions (PGMs) are generally characterized as weapons with terminal guidance systems. In addition to “smart” bombs, the term is applied to a wide variety of weapons, from air‐to‐air and air‐to‐ground missiles to wire‐guided torpedoes.
What is the difference between laser-guided and precision-guided bombs?
BOLT-117, the world’s first laser-guided bomb. A precision-guided munition (PGM, smart weapon, smart munition, smart bomb) is a guided munition intended to precisely hit a specific target, to minimize collateral damage and increase lethality against intended targets.
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.
Why do we need pre-Cision munitions?
Precision munitions also enhance strategic agility. For example, just over three C-5 sorties per day could have supplied every PGM used by the Air Force during the Gulf War. But the types of weapons in the US inventory remained largely unchanged since the end of the Vietnam War.
