Recent years the world advanced countries developed about the weapon system "the critical technology ", namely related technical ability development of weapon system, subsystem and module, the production and the operating process had to satisfy the operations requirements and the system specification technology of ability request. It has regarded as affects defense acquisition quality of important attribute. Therefore, our country national defense research & development program and defense acquisition plans whether can carefully appraise maturity of its critical technology, guarantees the weapon system quality, and defense acquisition management promotes to attain the work result, will be an important topic. In defense acquisition process, the US military utilizes "Technology Readiness Assessment, TRA" comments key of critical technology maturity the quantity weapon system development, and is fast and effective shift the advanced technology to the weaponry; defense acquisition management promotes to attain the work achievements. Counter-view our country according to defense acquisition process way, utilizing operations requirements document and system specification book carries out defense acquisition works. How as for carries out weapon system "Critical Technology Maturity Assessment, CTMA", still at the fuzzy stage. So will be able to make defense acquisition process to be long, is unable to complete the weapon to deploy as soon as possible, as well as effectively will save shortcoming and defense appropriations. Therefore, this paper takes the US new defense acquisition system as an example, takes its merit, develop a set of our country defense acquisition process CTMA work way. It can improve defense acquisition management related shortcoming. The technical development is fast, defense acquisition process has to reduce, and strictly examines defense acquisition process, then obtains more advanced and better weapon system. Therefore the CTMA work way refers to the US defense acquisition process to carry out the TRA, that develops suit our country "Technology Readiness Level, TRL" of utilization opportunity. It covers the weapon system development to be supposed factors, the weapon system function assessment, the technological development plan work and other applications. It provides a good critical technology to comment the quantity target, the system function assessment and the technological development plan of basic work way. It regards the national defense research & development program to construct the document work, but effectively grasps the weapon system critical technology or maturity of the advanced technological development, military accelerates to attain the effectiveness for a period of time, and defense acquisition management promotes to attain the quality. This research institute quotes "the missile system" development program to explain defense acquisition process to carry out the CTMA work, after the questionnaire survey result analysis, knew from the result that experts regarding related defense acquisition process to induct the CTMA work way and its future develop the spirit and the way, approval still are good, only detail of method and the correlation this work way of the consideration factor still wait for strengthens. In addition, some experts is not very agree the result, its main reason for various experts thought researcher correlation factor which deduces regarding the missile each group of sections module insufficient. An item of weapon system development, the consideration factors too be many, only depends on the literature to make the outline to inquire into is incomplete. In brief, the defense acquisition management faces technical multiplicity, complex, variable and noble character danger, developed it to this research institute "defense acquisition process to induct the CTMA work way" to provide an executive program and the method information. It might provide the managers decision-making to issue the reference, also might provide the workers to excavate more questions, and tried to improve and the revision as soon as possible. On future if will be able to expand this work energy, and establishment related work criterion, then this research on obvious its value.
