The primary considerations in the design and development of a recovery system applicable to present expendable first stage launch vehicles are discussed. The general requirements that define the essential characteristics of a feasible recovery system are derived from three critical phases during flight. The degree of criticalness is primarily influenced by the conditions at stage cutoff and separation.
