  • 1. ELECTROMAGNETIC BOMB6/13/2013 1
  • 2. Contents:Introduction.Basic Principle of E-Bomb.Technology Base for E-Bomb.Coupling Modes.E-Bomb Targets.Firing of E-Bombs.Defences Against E-Bombs.Military Applications of E-Bomb.Advantages and disadvantages.Conclusions.References.6/13/2013 2
  • 3. IntroductionThe most recent war operations relied on air power and precisionguided ammunitions.Future campaigns will require more suitable weapons to achieveshock effect over large targets with small attacking forces.Electromagnetic bombs (E-Bombs) can perform such a role.6/13/2013 3
  • 4. Basic Principle of E-BombThe Electro Magnetic Pulse (EMP) effect .The Electromagnetic Pulse is an electromagnetic shock wave.This pulse of energy produces a powerful electromagnetic fieldsufficiently strong to produce short lived transient voltages ofthousands of volts on exposed electrical conductors likewires, printed circuit boards etc.This can cause irreversible damage to wide range of electrical andelectronic equipments particularly computers and radio or radardevices.6/13/2013 4
  • 5. Technology Base for E-BombThere are two widely used technologies:Flux Compression Generators(FCG),andVirtual Cathode Oscillator or Vircator.6/13/2013 5
  • 6. Flux Compression Generators(FCG)FCG can produce tens of Mega Joules in tens to hundreds ofmicroseconds.Main parts of FCG include:Armature(copper tube).Stator(helical heavy wire coil).Initiator(plane wave explosion lens) and6/13/2013 6
  • 7. Contd…..Jacket(prevents disintegration due to magnetic field).FCG start current is provided by an external source.When start current peaks initiator is fired to initiate explosive burn.Explosive pressure expands armature and creates moving short.Moving armature compressses a magnetic field.6/13/2013 7
  • 8. Virtual Cathode Oscillator6/13/2013 8
  • 9. Contd…..Electron beam is accelerated through foil or mesh anode.Electrons passing through anode will form a bubble of space chargearound anode.Under proper conditions this space charge will oscillate at microfrequencies.Peak power of tens of GW for 100s of sec.Cheap and simple to manufacture.6/13/2013 9
  • 10. Coupling Modes:Front Door Coupling through antennas.Destroys RF semiconductor devices in transmitters and receivers.Back Door Coupling through power /datacabling, telephone wiring.Destroys exposed semiconductor devices.Punches through isolation transfomers.6/13/2013 10
  • 11. E-Bomb Targets:Fixed installations(buildings,radars etc.).Radiating mobileshidden targets(ships,mobiles).Non radiating mobileshidden targets.6/13/2013 11
  • 12. Firing of E-Bombs:Warhead comprises of priming current source,FCG(cascade) andVircator tube.Missile installations must supply 100% of weapon priming energyfrom own supply.Bomb installation-weapon can be precharged before release fromaircraft.A free fall E-Bomb is more lethal.6/13/2013 12
  • 13. Firing of E-Bomb6/13/2013 13
  • 14. Firing options:Aircraft Dumb bombs (free fall delivery).GPS or satellite guided bombs.standoff missiles.Cruise Missiles(weight restricted to 340kg).6/13/2013 14
  • 15. Defence and HardeningDestroy the delivery vehicle.Electromagnetically harden/hide important assets.Use optical fibres for data transfer and comprehensive shielding.Isolate power feeds with transient arrrestors.Use non-electromagnetic power feed and electromagnetic “airlock”.6/13/2013 15
  • 16. Hardening6/13/2013 16
  • 17. Military applications of E-Bomb:Electronic combat:The E-Bomb enables rapid attrition of enemy electronic assets overlarge areas.The E-Bomb offers important force multiplication effects comparedto conventional weapons.Strategic warfare:Economic vitals-finance and stockmarkets,manufacturing,petroleum are highly vulnerable.6/13/2013 17
  • 18. Contd…..Transport infrastructure-signalling and vehicle ignition systems arevulnerable.Population-radio and TV receivers.Military equipments are vulnerable.Theatre WarfareOffensive Counter Air operations-disable aircraft in flight,onground and destroy their supporting infrastructure.6/13/2013 18
  • 19. Contd…..Sea Control-disable surface combatants prior to attack withconventional weapons.Punitive Missions:The E-Bomb is a punitive weapon as it can cause much economicand military damage with no loss of civilian life.E-Bombs could be profitably used against countries which sponserterrorism and info-terrorism.6/13/2013 19
  • 20. Advantages:Not lethal to humans.Negligible collateral damage.No mass media coverage of bombing casualities(broadcastequipment destroyed)will reduce threshold for the use of strategicair power and missile forces.6/13/2013 20
  • 21. Disadvantages:Means of delivering E-Bombs are difficult.Difficulty in kill assessment.Atmospheric propagation of pulse.6/13/2013 21
  • 22. Conclusion:E-Bombs are weapons of electrical mass destruction.High payoff in using E-Bombs against fundemental infrastructureresults in substantial paralysis.Decisive advantage in the conduct of electronic combat.E-Bombs are non lethal weapon.The critical issues for next decade are the devolopment of E-Bombs and hardening of infrastructure.6/13/2013 22
