WHAT IS SMART BOMB…?
Highly accurate bomb,
equipped with Laser seeking guidance unit, computer and control fins;
Guided to its target by means of laser, infra- red or electro-optical system.
SMART BOMBS BASICS…
An electronic sensor system
A built in control system
( onboard computer )
A set of adjustable flight fins
A battery
HISTORY OF SMART BOMBS
WWI:
Kettering Aerial Torpedo- a small propeller driven aircraft.
1924:
Pilotless airplanes (guided by radio control)
WWII:
Germany develops 1st guided missile used in combat (V-1 & V-2)
AMERICA’S SECRET GUIDED WEAPONS
A standard bomb fitted with steering controls
GB-4: A TV camera to assist the controller with targeting
B-17: remote controlled weapon
PRECISION GUIDED AMMUNITION
TV/IR- Guided Weapons
1. Laser Guided Weapons
2. Joint Direct Attack Munition
3. Electro-optical Guided Weapons
4. Satellite- Guided Weapons
1) TV/IR- GUIDED BOMB
Conventional Television video camera
Infra red camera for night vision
Two Modes Of Operation:
1. Remote- Operation Mode
2. Automatic Mode
2. LASER GUIDED BOMB
Most common and wide-spread PGM’s
Use A Laser Designator :
to mark or illuminate a target
Strikes with greater accuracy than free-fall bombs
Generally unpowered
LIMITATIONS OF LGB’S
Designation
Vulnerable to Environmental Conditions
Accurate attack against a small target
A separate designator
Limited weapon basket
Problem of picking up wrong targets
3) JOINT DIRECT ATTACK AMMUNITION
Why JOINT…?
Meant to improve upon LGB’s and Infra-red technology
JDAM is a Guidance kit that converts unguided bombs into all-weather
“Smart Ammunition”
Uses Global Positioning System (GPS)
ADVANTAGES OF USING GPS:
A real all-weather capability
Expanded Launch Acceptance Region (LAR)
A true “ fire-and-forget” capability
Ability to completely tailor a flight trajectory
Accurate time source common to all systems
LIMITATIONS OF JDAM BOMBS
Not full-proof
If GPS guided weapon loses touch with the guiding satellite signals, it falls back on inertial navigation and calculates its position in relation to its last fixed position.
In such a situation the inaccuracy of JDAM rises to about 30 meters.
Since GPS-guided weapons aim at preprogrammed coordinates of the target. Coordinates of the target have to be precisely known.
CONCLUSION
Smart weapons have made bombing truly strategic. No longer a country needs to send hundreds of bombers to destroy one target.
As technology continues to advance, the face of warfare will continue to change.
