Explosively formed jets (EFJ) and fragments and self-forging penetrators (SFP) are used for precision strike against targets such as armored vehicles and reinforced structures. Current technology uses chemical explosive energy to form the jets and fragments. This is highly inefficient and requires precise machining of the metal liners from which the fragments and jets are formed. The Magneto Hydrodynamic Explosive Munition (MAHEM) program offers the potential for higher efficiency, greater control, and the ability to generate and accurately time multiple jets and fragments from a single charge.

The MAHEM program will demonstrate compressed magnetic flux generator (CMFG)-driven magneto hydrodynamically formed metal jets and SFP with significantly improved performance over EFJ. Generating multiple jets or fragments from a single explosive is difficult, and the timing of the multiple jets or fragments cannot be controlled. MAHEM offers the potential for multiple targeted warheads with a much higher EFJ velocity, than conventional EFJ/SFP. This will increase lethality precision. MAHEM could also be packaged into a missile, projectile or other platform, and delivered close to target for final engagement.
