What is PGM missile?

What is PGM missile?

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.

Do missiles have guidance systems?

Missiles and guided bombs generally use similar types of guidance system, the difference between the two being that missiles are powered by an onboard engine, whereas guided bombs rely on the speed and height of the launch aircraft for propulsion.

What are the two types of warheads that a guided missile can carry?

Strategic missiles usually carry nuclear warheads, while tactical missiles usually carry high explosives.

What is the difference b’n rocket and missile?

In other words, in a military context, a rocket is an unguided, rocket-powered weapon, with no steering ability. A missile is a self-propelled weapon, often rocket-powered (but not always), that has some kind of guidance system so that it can steer in flight, towards its target.

What is a PGM weapon?

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.

What is guidance system?

A guidance system is a virtual or physical device, or a group of devices implementing a controlling the movement of a ship, aircraft, missile, rocket, satellite, or any other moving object. One of the earliest examples of a true guidance system is that used in the German V-1 during World War II.

How does missile guidance system work?

The guidance system in a missile can be compared to the human pilot of an airplane. As a pilot guides his plane to the landing field, the guidance system “sees” its target. If the target is far away or otherwise obscured, radio or radar beams can be used to locate it and direct the missile to it.

What are different types of missiles?

There are five types, air-to-air, air-to-surface, surface-to-air, antiship, and antitank, or assault. Ballistic missiles are most often categorized as short-range, medium-range, intermediate-range, and intercontinental ballistic missiles (SRBMs, MRBMs, IRBMs, and ICBMs).

What are guided weapons systems?

The main objective of the Guided Weapon Systems course is to bring together the wide variety of disciplines constituting guided weapon systems technology and to present them in an integrated manner. The course structure is modular in nature with each module conducted at a postgraduate level.

What classifies a missile?

In military terminology, a missile, also known as a guided missile or guided rocket, is a guided airborne ranged weapon capable of self-propelled flight usually by a jet engine or rocket motor. Missiles have five system components: targeting, guidance system, flight system, engine and warhead.

What do you call an unguided jet propelled missile?

Airborne explosive devices without propulsion are referred to as shells if fired by an artillery piece and bombs if dropped by an aircraft. Unguided jet-propelled missiles are usually described as rocket artillery .

How are the aerodynamic characteristics of a missile determined?

The aerodynamic characteristics of a missile components such as body, wing and tail are calculated by using analytical methods to predict the drag and the normal forces of the missile. The total drag of the body is computed by using the parasite drag, wave drag, skin friction drag and base drag.

What kind of guidance system does a missile have?

Missiles have both propulsion systems and guidance systems. Most missiles also contain a payload (typically an explosive warhead), and also a proximity fuze*. Contrary to what you might expect, a missile does not have to hit its target to explode. Especially in the province of an air target.

What kind of missiles are used in aerial warfare?

Missiles come in types adapted for different purposes: surface-to-surface and air-to-surface missiles ( ballistic, cruise, anti-ship, anti-tank, etc.), surface-to-air missiles (and anti-ballistic ), air-to-air missiles, and anti-satellite weapons.
