  3. 3. Introduction The most recent war operations relied on air power and precision guided ammunitions. Future campaigns will require more suitable weapons to achieve shock effect over large targets with small attacking forces. Electromagnetic bombs (E-Bombs) can perform such a role. 6/13/2013 3
  4. 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 field sufficiently strong to produce short lived transient voltages of thousands of volts on exposed electrical conductors like wires, printed circuit boards etc. This can cause irreversible damage to wide range of electrical and electronic equipments particularly computers and radio or radar devices. 6/13/2013 4
  5. 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. 6. Flux Compression Generators(FCG) FCG can produce tens of Mega Joules in tens to hundreds of microseconds. Main parts of FCG include: Armature(copper tube). Stator(helical heavy wire coil). Initiator(plane wave explosion lens) and 6/13/2013 6
  7. 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. 8. Virtual Cathode Oscillator 6/13/2013 8
  9. 9. Contd….. Electron beam is accelerated through foil or mesh anode. Electrons passing through anode will form a bubble of space charge around anode. Under proper conditions this space charge will oscillate at micro frequencies. Peak power of tens of GW for 100s of sec. Cheap and simple to manufacture. 6/13/2013 9
  10. 10. Coupling Modes: Front Door Coupling through antennas. Destroys RF semiconductor devices in transmitters and receivers. Back Door Coupling through power /data cabling, telephone wiring. Destroys exposed semiconductor devices. Punches through isolation transfomers. 6/13/2013 10
  11. 11. E-Bomb Targets: Fixed installations(buildings,radars etc.). Radiating mobileshidden targets(ships,mobiles). Non radiating mobileshidden targets. 6/13/2013 11
  12. 12. Firing of E-Bombs: Warhead comprises of priming current source,FCG(cascade) and Vircator tube. Missile installations must supply 100% of weapon priming energy from own supply. Bomb installation-weapon can be precharged before release from aircraft. A free fall E-Bomb is more lethal. 6/13/2013 12
  13. 13. Firing of E-Bomb 6/13/2013 13
  14. 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. 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 “air lock”. 6/13/2013 15
  16. 16. Hardening 6/13/2013 16
  17. 17. Military applications of E-Bomb: Electronic combat: The E-Bomb enables rapid attrition of enemy electronic assets over large areas. The E-Bomb offers important force multiplication effects compared to conventional weapons. Strategic warfare: Economic vitals-finance and stock markets,manufacturing,petroleum are highly vulnerable. 6/13/2013 17
  18. 18. Contd….. Transport infrastructure-signalling and vehicle ignition systems are vulnerable. Population-radio and TV receivers. Military equipments are vulnerable. Theatre Warfare Offensive Counter Air operations-disable aircraft in flight,on ground and destroy their supporting infrastructure. 6/13/2013 18
  19. 19. Contd….. Sea Control-disable surface combatants prior to attack with conventional weapons. Punitive Missions: The E-Bomb is a punitive weapon as it can cause much economic and military damage with no loss of civilian life. E-Bombs could be profitably used against countries which sponser terrorism and info-terrorism. 6/13/2013 19
  20. 20. Advantages: Not lethal to humans. Negligible collateral damage. No mass media coverage of bombing casualities(broadcast equipment destroyed)will reduce threshold for the use of strategic air power and missile forces. 6/13/2013 20
  21. 21. Disadvantages: Means of delivering E-Bombs are difficult. Difficulty in kill assessment. Atmospheric propagation of pulse. 6/13/2013 21
  22. 22. Conclusion: E-Bombs are weapons of electrical mass destruction. High payoff in using E-Bombs against fundemental infrastructure results 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
