Kobe Steel, Ltd. formerly developed a new process for producing powdered rubber and constructed an actual plant with a capacity of 7,000 ton per year in Osaka in 1976 (l, 2). The powdered rubber is used as shock absorbing material for railway beds or as a filler for rubber products.

Objective Meet with representatives of Kobe Steel, Ltd., and GEOMET Technologies, LLC, to obtain information about Kobe Steel s DAVINCH controlled detonation munitions demilitarization process.

Various DAVINCH models, corresponding to various NEWs of the munition and its donor charge, have been built by Kobe Steel, Ltd., under the corporate mark KOBELCO, and used in Japan and Belgium to destroy chemical weapons. The technology has not been used in the United States.

Kobe Steel, Ltd., is also developing a transportable version of a DAVINCH whereby the vessel and offgas processing equipment would be carried on two flatbed trailers. Although a scale model of the unit exists, the committee does not know the status of design and fabrication of such a unit nor does it know about the unit s explosion containment, processing rate, or the range of items it can process. 

In tests, Kobe Steel, Ltd., has used linear shaped charges on the SFT of a simulated overpacked M55 rocket to demonstrate the ability to cut open the overpack and aluminum rocket body and to access and initiate the explosion of the simulated rocket warhead... 

Demonstration of the ability of the DAVINCH to destroy munitions in multiple overpacks and with packing materials placed between the overpacks. Kobe Steel, Ltd., has demonstrated the ability to access and destroy simulated overpacked M55 rockets using shaped charges. Similar demonstrations using simulated overpacked projectiles would be an extension of this activity. 

If, as proposed by Kobe Steel, Ltd., a DV65 were used to destroy four rocket motors per shot, then 17,500 shots (detonation events) would be required. The loading would be lairly high 35.2 kg energetics and 8.8 kg propellant per rocket. The associated donor charge would have to be sufficient to destroy the propellant but not so large as to exceed the 65 kg explosive con-tainment capacity of the DV65. The DAVINCH may well be able to process this number of shots. The iimer vessel is replaceable it can be rotated to distribute wear around its surface and is reinforced with four layers of steel around its outer perimeter.
