Creation in the modern terms of perspective types of armament, and, especially, based on new physical principles of action, is related to the considerable military-technical and financial risks. Classic approach, based on the "cascade" model of life cycle, does not allow to reduce these risks. There is a necessity of passing to more flexible systems development of armaments. In this article one of adaptive models life cycle is considered is a "evolutional" model with the planned changes, based on stage-bystage working off "critical" technologies and clarifications of requirements to the standard on the whole.
