Strategy Page looks at some interesting developments in the electronic weapons area:
A U.S. government report (from the National Ground Intelligence Center) indicates that China has developed useful weapons for disabling the electronics on American aircraft and warships. This is done using high-powered microwave (HPM) devices to create something like the EMP (Electromagnetic Pulse) put out by nuclear weapons, which damaged or destroys microelectronics.

Then there’s the EMP bomb, a legendary weapon that is much talked about, but has never actually been seen. Throughout the 1990s, information came out of Russia that a weapon had been developed that could generate a short range EMP (electromagnetic pulse) similar to that created by nuclear explosions. All computers within the range of the EMP bomb would be ruined. This is a truly devastating capability. Microprocessors are found everywhere these days; in automobiles, appliances, industrial equipment, medical devices and many other devices. Military microprocessors are often shielded to protect them against EMP, but the shielding is not thoroughly tested and even some military equipment will probably be disabled by an EMP attack.
A decade ago, a British military research team announced that they had duplicated the rumored Russian device and produced an EMP bomb that can fit in a 155mm artillery shell, small rockets or bombs. Such a device was supposed to be inexpensive and could be used to destroy civilian electronics that might be useful to nearby enemy troops. What is particularly worrisome about this new development is that, in the hands of terrorists, it could do a new kind of damage. While not killing people directly, the destruction of all electronics within an urban area could cause casualties and much economic loss. But none of these EMP bombs has ever actually reached the stage where they were actually ready to use. There was always some kind of flaw discovered in testing. Naturally, China is thought to have developed an EMP bomb.
