FMU-160/B

“Approved for Public Release by AMSTA-AR Form 3002 dated 01 July 96.”

KDI Precision Products, Inc. is recognized worldwide as a technology leader in the development of highly sophisticated systems for Radio Frequency (RF) proximity and sensing applications.  Whether it is today’s most advanced FM proximity system or a simple continuous wave (CW) system, KDI has the knowledge, expertise, and facilities to design, develop, manufacture, and test a high-reliability, low cost solution to meet customer needs. The FMU-160/B was developed by KDI under an IRAD program. This design is based on a simplified version of the M734A1 Multi-Option Fuze for Mortar (MOFM).

The fuze has been optimized for ground targets with a Height of Burst (HOB) of 15 feet and includes an impact backup function. The FMU-160/B has excellent immunity to RF noise sources. This is a low cost fuze for 105 MM ammunition and can be used on 76 MM, 5”, and 155 MM applications.

KDI has produced in excess of 20,000 fuzes to date with a near perfect ballistic firing reliability record in Lot Acceptance Testing. KDI’s engineering capabilities are  fully demonstrated where unique, cutting-edge sensor technology is combined with modern electronic components to provide a fully integrated munition device. Production of this assembly in our modern high quality manufacturing facility has yielded excellent field results.

The High Fragmentation Fuze electronics employ microprocessor- based logic together with state-of-the-art Gallium Arsenide (GaAs) RF technology packaged into a Flex Cable  assembly using modern surface mount technologies. This new design provides more accurate height of burst and is ECM hardened. KDI’s development expertise is an outgrowth of many years of experience in the design and development of RF proximity fuzing systems for its valued Department of Defense customers. Design and developmental  activities are centered in the new, well-equipped KDI laboratories which efficiently accommodate the various technical disciplines embodied in KDI products. These facilities include mechanical laboratories for the development of precision mechanisms and electromechanical devices; electronics laboratories for the development of electronic circuits, systems, and equipment; a surface mount technology laboratory, including pick-and-place equipment; a RF anechoic chamber, and range simulators for proximity sensor R & D.

KDI houses and utilizes a full range of standard electronic test equipment. The KDI calibration system was designed and implemented to meet MIL-STD-45662. The system employs a computerized recall of gauges and test equipment which contains data that defines calibration item status, recall frequency, location, related program usage, and a historical  calibration file of the last 10 calibration results. For applications from DC to gigahertz to optical wave length, KDI has an effective, efficient solution.
