59 -- M439 FUZE INTEGRATED CIRCUIT (IC) AND TESTING OF THE FUZE WITH THE IC DUE 022500 POC Mary Lou Desseaux, Contract Specialist, 973-724-3217 WEB: US ARMY TACOM-ARDEC Procurement Network, http://procnet.pica.army.mil/cbd/SRCSgt/011020000/011020000.htm. E-MAIL: Mary Lou Desseaux, mdess@pica.army.mil. The U.S. Government is seeking to fabricate a state of the art IC to replace the discrete components of the M439 remote set fuze for the 2.75-Inch Rocket System. This effort will involve fabrication of the M439 fuze Molded Electronics Module (MEM) with the new IC, complete prototype testing and First Article Testing (FAT). The M439 fuze is a remote set fuze for the 2.75-Inch Rocket System cargo warheads. The MEM of the fuze contains the time delay circuitry and the timing and firing capacitors. The circuit contains various transistors, diodes, resistors and capacitors. The IC will replace most of the current discrete components, which are becoming increasingly difficult to procure. After fabrication of the IC, prototype testing will be performed. Subsequently the IC will be incorporated into the MEM and timing tests will be performed according to the M439 fuze specification, MIL-F-48877. After the MEM passes the laboratory testing, ballistic FAT will be conducted to verify that all timing requirements are met with the new IC under live fire conditions. The IC will not affect the form, fit or function of the current M439 MEM. Complete specification control drawings for the IC will be generated allowing it to be procured in the future from various semiconductor suppliers. A final report and the drawing package of the fuze circuit will also be generated. The contractor will be responsible for all the above work including the design and fabrication of the IC, MEMs and all the testing including the FAT. The contractor will be responsible for acquiring M439 fuzes, assembling MEMs, with the new IC into the fuzes and passing government conducted ballistic testing. Posted 01/10/00 (D-SN414495). (0010)
