The three penetrators tested at Pendine contained accelerometers, a data acquisition system, a power system and sensors including a drill mechanism, seismometer and mass spectrometer.
Soon after the attacks of September 11, 2001, the Bush Administration made a push for new nuclear programs, the most conspicuous of which was the Robust Nuclear Earth Penetrator (RNEP), designed to destroy deeply buried bunkers.
Large numbers of corroding DU penetrators buried in the soil may also pose a long-term threat if the uranium leached to water supplies.
On contamination of the water supply, for instance: It is probable that many penetrators and jackets are hidden at some metres depth in the ground.
''However, the amount of transuranic isotopes found in the DU penetrators is very low that they do not have any significant impact on their overall radioactivity,'' Topfer said.
During tests conducted in November and December, however, the penetrators' circuits were disconnected due to damage to one part of the onboard equipment caused by defective adhesive.
diameter) ball penetrator that presses into the mold surface under a spring load of 980 g.

The Brigades is a group supported by Iran and its members are using missiles and explosively formed penetrators (EFPs) in civilian areas, the statement noted, not giving more details.
However, mountain caves and deep bunker targets support the continued development of penetrators. Penetration can be improved by increasing mass and impact velocity, by using a more slender shape, by having the warhead impact at 90 degrees to the surface, and (in the context of concrete or masonry) by using a shaped-charge precursor.
During tests, however, a liquid leaked from the battery for one of the probe's spear-shaped observation widgets called the penetrators, in which seismic instruments are kept.
