Only a small fraction of the roadside bombs used in Iraq are explosively formed penetrators.

According to one military official, reports of the "explosively formed penetrator," as the weapon is known, first surfaced in late 2003.

The most lethal development is the use of the "explosively formed penetrators," which pierce armor and stay intact when they explode.

A relatively new type of remotely-detonated mine, the explosively formed penetrator was used with some success against American armored vehicles.

The properties of metals under hypervelocity have been integrated with weapons, such as explosively formed penetrator.

Kill mechanism: Explosively formed penetrator and fragmentation.

Due to its high density, shaped charge and explosively formed penetrator liners have been constructed from tantalum.

The explosion will form a copper explosively formed penetrator hitting the asteroid with a velocity of 2 km/s.

The four men are suspected of helping shuttle into Iraq a deadly type of homemade bomb called an explosively formed penetrator, the military said.

Overtime, insurgency groups moved to more sophisticated methods of attack such as Explosively formed penetrators, and infrared lasers, which cannot be easily jammed.

By late 2006 these bombs, known as explosively formed penetrators, or E.F.P.'s, were killing a larger number of Americans.

American troops are increasingly being attacked by deadly hidden bombs, called explosively formed penetrators, or E.F.P.'s.

Inside the actual device is C4, and this is used to form the copper into an explosively formed penetrator and turn it into a weapon.

When a target is acquired, an explosively formed penetrator is fired from a top-down position, to exploit the weaker top armor of tanks.

Explosively formed penetrators (EFPs) can also defeat the armor kits, causing casualties.

Under the camouflage was a massive, six-array, explosively formed penetrator a deadly roadside bomb that cuts through the Humvees armor with ease.

Then, as now, those devices were the devastating roadside bombs currently called E.F.P.'s (explosively formed penetrators).

DARPA predicts the weapon will have greater efficiency, control, and precision than conventional explosively formed penetrators.

The canisters, called explosively formed penetrators or E.F.P.s, are perhaps the most feared weapon faced by American and Iraqi troops here.

At least eight of the recent attacks in the area have used explosively formed penetrators, or E.F.P.'s, powerful bombs able to pierce armored Humvees.

Modern guided submunitions, such as those found in the U.S. CBU-97, can use either a shaped charge or an explosively formed penetrator.

Small Carry-on Impactor (SCI) is a small drop off Explosively formed penetrator.

The concern intensified toward the end of 2006 as American casualties from the explosive devices, known as explosively formed penetrators, or E.F.P.'s, began to climb.

This armour kit is intended to provide increased protection against Improvised explosive device, Explosively formed penetrator and 30 mm caliber armour piercing rounds.
