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.

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.

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

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

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

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.

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.

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.

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