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 enemys

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

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 lensefired to initiate explosive burn.

l Explosive pressure expands armature and

creates moving shortl Moving armature compresses magnetic

field

Coupling Modes:

Front Door Coupling through antennas.

l Destroys RF semiconductor devices in

transmitters and receiversBack Door Coupling through power/data

cabling, telephone wiring

l Destroys exposed semiconductor devicesl Punches through isolation transformers.

Damage Mechanisms:

l Low frequency pulses produced by FCGcreate high voltage spikes on fixed wiring

infrastructure.

l Microwave radiation from HPM devicescan couple directly through ventilation

grilles, gaps between panels, poor interface

shielding - producing a spatial standingwave inside the equipment cavity.

Maximising Bomb Lethality:

Lethality is maximized by maximizing thepower coupled into the target set.

l Maximize peak power and duration ofwarhead 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.

E-bomb Advantages in

Strategic Warfarel 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

7/30/2019 e-bomb_ppt

18/20

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.
