Formation of an EFP warhead. USAF Research Laboratory.. An explosively formed penetrator (EFP), also known as an explosively formed projectile, a self-forging warhead, or a self-forging fragment, is a special type of shaped charge designed to penetrate armor effectively, from a much greater standoff range than standard shaped charges, which are more limited by standoff distance.
Frag Kit 6 is a vehicular armor upgrade kit developed by the U.S. Army Research Laboratory to defeat explosively formed projectiles (EFP), a type of armor penetrator often utilized in improvised explosive devices (IED). It is designed to be added on armored vehicles such as the MRAP and unarmored Humvee. [1]
In July 2018, Czechia provided EFP Lithuania the 1st Company Task Force consisting of a mechanized company with Pandur armored vehicles reinforced by an engineer platoon, a logistics unit and a medical element reaching a total of 230 people. [42] After six months, they were replaced by the 2nd Task Force for the next half-year. [42]
The EFP is relatively unaffected by first-generation reactive armor and can travel up to perhaps 1000 charge diameters (CD)s before its velocity becomes ineffective at penetrating armor due to aerodynamic drag, or successfully hitting the target becomes a problem. The impact of a ball or slug EFP normally causes a large-diameter but relatively ...
The M303 Special Operations Forces demolition kit is a kit containing various metal and plastic parts which the SOF operator packs with C4 explosive to produce a shaped charge or an explosively formed penetrator.
An EFP, on the other hand, has a liner in the shape of a shallow dish." The purpose of the metal liner inside the conical cavity of the shaped charge is to add greater mass to the "jet" enabling greater penetration. It should be noted that these liners are far thinner than the disk found on EFP/SFF's.
In manual laying. a clod is cut, larger by one half than the mine diameter and a well is dug so that the clod of 2–3 cm is protruding by 2 cm above the ground. The mine is laid in the well, the safety element is taken off, safety is set at 1 or 4 minutes the starter is pressed (the fuze bar is fitted) and the mine camouflaged.
Electronic field production (EFP) is a television industry term referring to a video production which takes place in the field, outside of a formal television studio, in a practical location, special venue or fitting environment. Zettl [1] defines EFP as using "both ENG (electronic news gathering) and studio techniques. From ENG it borrows its ...
