Abstract: The evolution of Military Specifications for Airplane Strength and Rigidity of USAF and USN is presented. The common Military Specifications-MIL-A-8860 (ASG) was applied in the procurement of USAF and UAN in the 1960's, but USAF and USN promulgated MIL-A-87221 (USAF) and MIL-A-8860B (AS) for the procurement of airplanes in the mid of the 1980' s, separately. The revisions of Military Specifications during the twenty five years are presented. The changes in the requirements such as life, loads spectra, fatigue test articles, test schedule, fatigue scatter factors and management are analysed in detail. Finally, the concept of economic life (durability technques), which is only used by USAF, is reviewed.

Key words: Military Specifications, life, loads/environment spectra, scatter factors, force management
