1. MISSILE
CLASSIFICATION
DINESH BABU.V -AP/AERO-NIET

2. MISSILE DEFINITION
 Missiles differ from rockets by virtue of a guidance
system that steers them towards a pre-selected target.
 Missiles are generally classified on the basis of their
Type, Launch Mode, Range, Propulsion, Warhead and
Guidance Systems.

3. PORTRAIT OF
TIPU SULTAN
 Unlike contemporary rockets
whose combustion chamber was
made of wood (bamboo).
 Tipu's rockets (weighing between
2.2 to 5.5 kg) used iron cylinder
casings.
 The British were greatly
impressed by the Mysorean
rockets using iron tubes

7. ON THE BASIS OF TYPE
(i) Cruise Missile:
 A cruise missile is an unmanned self-propelled (till the time of impact)
guided vehicle that sustains flight through aerodynamic lift for most of its
flight path and whose primary mission is to place an ordnance or special
payload on a target.
 They fly within the earth’s atmosphere and use jet engine technology
 Depending upon the speed such missiles are classified as:
 1) Subsonic cruise missile
 2) Supersonic cruise missile (BRAHMOS)
 3) Hypersonic cruise missile (BRAHMOS II)

8. BASED ON MISSILE TYPE
(ii) Ballistic Missile:
 A ballistic missile is a missile that has a
ballistic trajectory over most of its flight
path, regardless of whether or not it is a
weapon-delivery vehicle.
 . The missile carry a huge payload. The
carriage of a deadly warhead is justified
by the distance the missile travels.
Ballistic missiles can be launched from
ships and land based facilities.
 example, Prithvi I, Prithvi II, Agni I, Agni
II and Dhanush ballistic missiles are
currently operational in the Indian
defence forces.

12. BASED ON WARHEAD
 A warhead is an explosive device used in military conflicts, used to destroy enemy
vehicles or buildings.
 Typically, a warhead is delivered by a missile , rocket or torpedo. It consists of the
explosive material, and a detonator.
Types of warhead :-
Explosive:
An explosive charge is used to disintegrate the target, and damage surrounding areas
with a shockwave.
Chemical:
A toxic chemical, such as nerve gas is dispersed, which is designed to injure or kill
human beings.
Biological:
An infectious agent, such as anthrax is dispersed, which is designed to sicken and kill
humans.
Nuclear:
A runaway nuclear fission or fusion reaction causes immense energy release.DINESH BABU.V -AP/AERO-NIET

13. GUIDANCE SYSTEMS
GUIDANCE SYSTEM:
Missiles may be targeted in a number of ways. The most common method is to use
some form of radiation , such as infrared , lasers or radio waves , to guide the missile
onto its target.
THERE ARE TWO TYPES OF GUIDANCE SYSTEM:
 fire-and-forget
 Another method is to use a TV camera—using either visible light or infra-red—
in order to see the target.
GUIDENCE CLSSIFICATION:
 Wire Guidance
 Command Guidance
 Terrain Comparison Guidance
 Terrestrial Guidance
 Inertial Guidance
 Beam Rider Guidance
 Laser Guidance

BEAM RIDER GUIDENCE:
The beam rider concept relies on an external
ground or ship-based radar station that
transmits a beam of radar energy towards the
target
LASER GUIDANCE: In laser guidance, a laser
beam is focused on the target and the laser
beam reflects off the target and gets scattered.
The missile has a laser seeker that can detect
even miniscule amount of radiation. The seeker
provides the direction of the laser scatters to the
guidance system. The missile is launched
towards the target.
TERRAIN CONTOUR MATCHING
(TERCOM)-
This method uses a ground scanning radar to
"match" topography against digital map data
to fix current position. Used by cruise missiles

15. WIRE GUIDENCE:
 A wire-guided missile is a missile that is
guided by signals sent to it
 via thin wires connected between the
missile and its guidance
 mechanism, which is located somewhere
near the launch site.
RF AND GPS REFERENCE:
 A missile uses GPS signal to
determine the location of the
target.
 Over the course of its flight, the
weapon uses this information to
send commands to control surfaces
and adjusts its trajectory.
 In a RF reference, the missile uses RF
waves to locate the target.
