INTRODUCTION

•  SBL is a next generation directed energy

missile defence

•  Laser weapons, based in space and capable of

the global projection of power to attack a wide

range of targets.

 

NEED OF SBLD

 The laser offers the potential to destroy missilesduring the boost phase.

 

KILL MECHANISM

• Electronic circuits

• Detonate the fuel tanks

• Rupture the fuel tanks

 

ARCHITECTURE OF SBL

Four major subsystems:

• A laser device

• Optics and beam control system

•   Acquisition, tracking, pointing and fire control (atp/fc) system

•   Associated space systems

 

 Three laser systems are being considered for

space-based laser weapons. These are all

chemical lasers and involve mixing chemicals

together inside the laser cavities to create the

laser beam.

The competing lasers are hydrogen fluoride

(HF), deuterium fluoride (DF), and chemical

oxygen iodine (COI).

 A Laser Device 

 

Optics And Beam Control System

The optical components not only “direct”  the laser

 beam to its target, but they also relay the laser energy

and when required, correct for any atmospheric

turbulence that will distort the beam.

 

Adaptive Optics

These systems use sophisticated optics in order to

“pre-compensate”  the laser beam for atmospheric

turbulence.

Acquisition, Tracking, Pointing and Fire

Control System

A SBL needs to locate the missile (acquisition),track its motion (tracking), determine the laseraim point and maintain the laser energy on thetarget (pointing), and finally swing to a newtarget (fire control).

 

Associated Space Systems

The associated space systems provide the

necessary electrical power, command and

control, laser reactants, and on-board data

 processing.

 

 ARCHITECTURE EVALUAION

  The SBL concept has to overcome several significanttechnological and operational challenges.

  The operational concerns are related to its on-orbitlogistics.

  Since the laser is chemically fueled, the space-basedlaser is only capable of a limited number of shots(75)

 before its fuel is depleted.

 

CONCLUSION

• Space has provided a new dimension to

warfare with the domain of conflict extending

from Earth to Space.

• Therefore, to safeguard our territory and

 people, India must develop and integrate the

Space Based Laser Defence system with the

 National Air Defence network, desirably

under the functional control of IAF.
