Other Completed Mine/Vegetation

Enhanced Tele-Operated Ordnance
Disposal System (ETODS). The ETODS is an integrated system
operated via remote control to help deminers safely clear vegetation and
excavate and neutralize landmines. The ETODS can accommodate a
number of attachments for specific missions. A commercial boom may be
attached for grass and vegetation mowing and the clearing of small trees.
A flail may be used for direct mine neutralization. Mines or suspicious
objects already marked or identified with GPS coordinates can be re-located
with an on-board commercial detector, then excavated with a modified commercial
backhoe, an air knife, excavation bucket, or gripper attachment. The ETODS
can be configured with a commercial GPS with less than one meter accuracy.
With the proper combination of tools, an AP mine can be excavated in 5
minutes, an AT mine in 10. This equipment has withstood AT and bounding
fragmentation AP mines with reparable damage. This device completed
operational field evaluations in Jordan and Egypt, where it was found
to have several significant limitations which make it less than suitable
for humanitarian demining operations. These include the tendency to become
mired in mud or desert sand conditions, as well as the requirement for
significant training to develop tele-operation skills.

Mini-Flail. The Mini-Flail
is a remotely controlled flailing system designed to detonate bounding,
tripwire fuzed and simple pressure activated antipersonnel mines. It has
been used for vegetation clearance, quality assurance, and perimeter reduction.
The Mini-Flail has undergone successful field evaluations in
Bosnia, Kuwait, and Jordan.

| Berm Processing Assembly (BPA).
The BPA was developed during FY 1995-1996. The system sifts mines from
earthen berms created by mine clearing equipment during large area clearance
operations. The FY1995 test results identified the need for more power to
effectively reduce berms. The BPA was redesigned in FY1996. A prototype
was sent to Namibia for an operational evaluation. The system was subsequently
converted into a stationary sifting system. The BPA continues
to be used in Namibia. |

Commercial Shaped Charges (Oil
Well Perforators). Commercial shaped charges are an alternative
to conventional means for neutralization of landmines. In FY1995, small,
inexpensive commercially available shaped charges were evaluated as a
mine neutralization alternative. The shaped charges detonated all AT
and AP mines during testing with significantly less explosive than standard
demolition charges. The shaped charges are available from several
commercial sources, including Western Atlas International, Shaped Charge
Specialists Inc., Accurate Arms Company Inc., and Guiberson AVA Dresser.

Seismic Countermine Vehicle. In
FY1997, this project explored the use of oil well exploration equipment
to aid in the detection and neutralization of landmines. The system was
intended to induce horizontal shear waves into the ground, causing the
rupture of the hard packed surface of mined areas. It was intended to
loosen the soil, and potentially expose mines to infrared and other optical
detection sensors. This technique proved ineffective in field tests
and the project was terminated.

Swedish Mine Fighter. The
Swedish Mine Fighter is an AP mine clearance device. It consists
of an assembly of spikes attached to a commercial forklift. A hydraulic
system is used to extend and retract each set of twenty-five spikes into
the ground. It functions by hydraulically pressing each set of spikes
into the soil, spearing and detonating whatever mines it encounters. Though
it has proven effective against most pressure-fuzed blast AP mines and
can withstand blasts from large AP mines (PMN, M16), too frequently it
spears mines without detonating them, thus rendering the mines unstable
and very dangerous. The Swedish Mine Fighter failed to meet certain
mission effectiveness criteria. Specifically, a sixty-four percent clearance
rate is unacceptable, as is the glaring inability of the system to neutralize
such commonly found mines as the VS-50 and TS-50. Therefore, based
on its performance, the Swedish Mine Fighter cannot be recommended
for demining at this time. Future potential of this system is recognized
if neutralization capability and robustness are increased.
