3. Missile is a weapon or object that is thrown
at a target
OR
A projectile that is, something thrown or
otherwise propelled

4. There are two types of missiles.
UNGUIDED OR BALLISTIC MISSILES which
moves freely to the target and can’t be
controlled after launching e.g. missiles of
tank
GUIDED MISSILES which are guided through
some remote controls e.g. Cruise missile

5. A cruise missile is basically a small
unmanned aircraft.
They are also called as unmanned aerial
vehicles (UAV).
Cruise missiles are designed to deliver a
large warhead over long distance with high
accuracy.
Modern cruise missiles can travel at
supersonic or high subsonic speeds, are
self-navigating .

6. Tomahawk Cruise missile

7. Cruise missiles:
1. have 8.5-foot (2.61-meter) wingspan
2. powered by turbofan engines
3. can fly 500 to 1,000 miles (805 to 1,610
km) depending on the configuration.
4. deliver a 1,000-pound (450-kg) high-explosive
bomb to a precise location of
the target.

10. Cruise missile generally consist of
1. Guidance system,
2. Payload, and
3. Propulsion system,
housed in an airframe with small wings.
Payload usually consist of a conventional
warhead or a nuclear warhead.
Cruise missile is propelled by a jet engine.

11. Cruise missiles can be categorized by
1. size
2. speed(subsonic/supersonic),
3. range,
or
4. whether launched from:
i. land,
ii. air,
iii. ship,
iv. submarine.

12. Air and submarine launched versions are a
little lighter and smaller than land- and ship-launched
versions.
Larger missiles can carry either a
conventional or a nuclear warhead, while
smaller ones can carry only conventional
warhead .

15. The purpose of a guidance system is to direct the
missile to target .
Use of an automatic target recognition (ATR)
algorithm/device in the guidance system increases
accuracy of the missile.

16. Inertial navigation system
TERCOM (Terrain Contour Matching)
DSMAC (Digital Scene-Mapping Area Correlator)
Satellite navigation

17. An inertial navigation system includes
1. a computer and a platform containing
accelerometers,
2. gyroscopes,
or
3. other motion-sensing devices.
Accelerometers measure the vertical, lateral, and
longitudinal accelerations of the controlled
missile .
Gyroscopes measure the angular velocity of the
system.

18. INTERNAL NAVIGATION SYSTEM

19. It uses a pre-recorded contour map of the terrain
that is compared to measurements made during
flight by an on-board radar altimeter.
The missile's radar altimeter feeds measurements
into a smaller buffer, and averages them out to
produce a single measurement.
The series of such numbers a strip of
measurements similar to those held in the maps.
The two are compared to overlay the strip on the
known map, and the positioning of the strip within
the map produces a location and direction.

20. TERCOM (Terrain Contour Matching)

21. A series of photographs are taken from
surveillance aircraft and are put into a carousel in
the missile.
Another camera takes pictures out of the bottom
of the missile.
A computer compares the two images and
attempts to line up areas of high contrast.
This system is very slow and its role is being
taken up by TERCOM.

22. DSMAC (Digital Scene-Mapping Area Correlator)

23. Using a satellite positioning system, such as GPS.
Satellite navigation systems are precise and
cheap.
If the satellites are interfered ten, the satellite
navigation system becomes inoperable.
The GPS-based navigation is useful in a conflict
with a technologically unsophisticated adversary.

24. Satellite navigation

25. The big advantage of the cruise missile is its
smallness and cost.
Its small size also improved the weapon’s chances
of penetration.
The map matching system (TERCOM) is combined
with an inertial navigational system in a system
called TAINS. This not only gets the cruise missile
to its target but also with an high accuracy.

26. The lack of a human pilot means you can't re-use
the thing, whereas you can get multiple missions
out of a piloted aircraft.
Their low and slow flight means they can be
engaged by a much wider variety of systems.
The missiles aren't always accurate, they're
expensive..

28. On June 12/2001, the BrahMos cruise missile took off from
its launched at Chandipur-on-a- Sea, Orissa, and reached a
speed of up to mach 2, it becomes the first ever supersonic
cruise missile that used liquid ram jet technology.
The missile, with range of 280 k, weighted three tones.
The BeahMos will not carry nuclear warhead because it is an
anti ship missile that can be launched from ships,
submarines, aircrafts and land
The BrahMos is a product of an INDO-RASSIAN joint venture
known by the same name.

29. The BrahMos missile,
1. Travelling at 2.8 to 3 times the speed of sound
(mach2.8to3)
2. Is three times faster than a subsonic cruise
missile such as the Tomahawk of the U.S.
3. Has 9 times the killing power because the killing
power is proportional to the square of the
velocity.

30. In most recent attacks on Afghanistan and
Iraq, America depended mostly on cruise
missiles to attack different target.
Success rates for both strikes were above
90%.
In all ,cruise missiles firing power shows a
greater tan 85% accuracy rate

31. Currently cruise missiles are among the most
expensive of single-use weapons, up to several
million dollars apiece. However, they are cheaper
than human pilots when total training and
infrastructure costs are taken into account.
Guidance System used in cruise missile is a
complex system which involves several systems
working in random. it is essential that guidance
system is properly designed for accurate
interception of targets.
