1. The E-bomb - A Weapon of Electrical Mass Destruction

2. l Introduction.
l E-bomb technology base. l Physics of the FCG. l External sources. l FCG internals. l FCG operations. l Coupling modes. l Damage mechanism.
l Advantages over ordinary bomb. l Conclusion.

3. Introduction:
l It is a Future weapon i.e. they are a more suitable weapon than conventional weapon to achieve shock effect over large target sets with small attacking forces.
l Electromagnetic bombs (E-bombs) can perform such a role.
l The objective is to paralyze the enemy’s communication systems as quickly as possible.

4. Power supply
co-axial Pulse capacitor FCGs shaping battery bank Electromag netic pulses
network Vircator tube Microwave antenna

5. E-bomb Technology Base:
l Power source - Explosively pumped Flux Compression Generator (FCG).
l FCG invented by Los Alamos Labs during the 1950s.
l Peak current of an FCG is 1000 X that of a typical lightning stroke.

6. The Physics of the FCG:
- FCG transfers mechanical energy into the magnetic field
- Peak currents of Mega Amperes demonstrated in many experiments

7. FCG start current is provided by an external source:
l High voltage capacitor bank
l MHD (magneto hydrodynamic) device
l Any device that generate mega amperes current pulse.

8. FCG Internals:
l Armature - Copper tube / fast explosive l Stator - Helical heavy wire coil
l Initiator - Plane wave explosive lense
l Jacket -Prevents disintegration due to magnetic forces

9. FCG Operation:
l External power source pumps FCG winding with start current.
l When start current peaks, explosive lense fired to initiate explosive burn.
l Explosive pressure expands armature and creates moving short
l Moving armature compresses magnetic field

10. Coupling Modes:
Front Door Coupling through antennas. l Destroys RF semiconductor devices in transmitters and receivers
Back Door Coupling through power/data cabling, telephone wiring
l Destroys exposed semiconductor devices l Punches through isolation transformers.

11. Damage Mechanisms:
l Low frequency pulses produced by FCG create high voltage spikes on fixed wiring infrastructure.
l Microwave radiation from HPM devices can couple directly through ventilation grilles, gaps between panels, poor interface shielding - producing a spatial standing wave inside the equipment cavity.

12. Maximising Bomb Lethality:
Lethality is maximized by maximizing the power coupled into the target set.
l Maximize peak power and duration of warhead emission (using powerful FCG).
l Maximize coupling efficiency into target set.

13. Defenses Against E-bombs:
l Destroy the delivery vehicle or launch platform
l Electromagnetically harden important assets.

14. E-bomb Advantages in Strategic Warfare
l Not lethal to humans.
l Negligible collateral damage.
l No mass media coverage of bombing casualties (broadcast equipment destroyed) will reduce the threshold for the use of strategic air power and missile forces

15. Conclusions:
l High payoff in using E-bombs against fundamental infrastructure, resulting in substantial paralysis.
l E-bombs will become a decisive capability in Strategic Warfare and Electronic Combat.
l E-bombs are a non-lethal weapon.
l The critical issues for the next decade are the deployment of E-bombs and the hardening of fundamental infrastructure.
