This handbook is approved for use by the Department of the Army and is available for use by all Departments and Agencies of the Department of Defense. 2. This handbook is for guidance only. Do not cite this document as a requirement. If it is, the contractor does not have to comply. 3. This handbook was developed to provide guidance and general approaches to the develop- ment of fire control systems. In particular, the handbook has been prepared to aid the designers of Army fire control equipment and to serve as a reference guide for all military and civilian person- nel who may be interested in the design aspects of such materiel. The guidance in this handbook is based on the fundamental parameters of the fire control problem and its solution. Primary emphasis is placed on the systematic approach required in the design of present-day fire control equipment and systems. This approach involves thorough analysis of the particular fire control problem at hand, establishment of the most suitable mathematical model, and computerization and mechanization of the mathematical model. 4. This handbook was developed under the auspices of the US Army Materiel Command’s Engineering Design Handbook Program, which is under the direction of the US Army Industrial Engineering Activity. Research Triangle Institute was the prime contractor for this handbook under Contract No. DAAA09-86-D-0009. The development of this handbook was guided by a technical working group chaired by Ms. Robin Gullifer of the Fire Support Armament Center of the US Army Armament Research, Development, and Engineering Center. 5. Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to Commander, US Army Arma- ment Research, Development, and Engineering Center, ATTN: AMSTA-AR-EDE-S, Picatinny Arsenal, NJ 07806-5000, by using the Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter. ii Thi d t t d ith F M k 4 0 4 Downloaded from http://www.everyspec.com MIL-HDBK-799 (AR) CONTENTS FOREWORD
