This paper presents the means of improving the strength of LTV's FRP structure for resolve and prevent quality problems. LTV secures enough kerb weight by applying FRP materials at hood and rear van assembly. However, because of FRP's inherent limitations, many initial quality problems such as crack at connections have occurred. Moreover, hood assy' is concerned about fall of endurance, because hood assy' have operated in abnormal condition. Therefore, this study executes lamination structure optimizations of FRP structure for improving bending strength. As a results, hood and rear van's bending strength at connections is improved 8.1 times and 1.5 times, respectively. Also hood assy's plate secures endurance life and improve 1.7 times of critical load about abnormal operating conditions through 1.4 times improvement of bending strength.

Based on the characteristics of the weapon system, a government-funded research institute or a defense industry company is selected as the R&D supervision institution. On the other hand, research for the selection of a R&D supervision institution has not been conducted actively. This paper proposes a methodology for selecting R&D supervision institutions, such as procedure and indices. First, candidates of the index were obtained using data investigation and consulting, and five indices were deduced using Delphi. The weight of the indices was set using AHP. The high element consisted of 'Technical elements' and 'Business element'. The low element of 'Technical elements' consisted of 'Possession and readiness of critical technology' and 'Experience of similar R&D'. The low element of 'Business element' consisted of 'Base circumstance of the project', 'Risk management', and 'Will for the project'. The total weights of the indices were 'Possession and readiness of critical technology' 0.405, 'Experience of similar R&D' 0.297, 'Base circumstance of the project' 0.124, 'Risk management' 0.127, and 'Will for the project' 0.047. The indices were applied to the 00 weapon system and the result was deduced.

There are many demands for interoperability between weapon systems as the operational needs for joint and coalition based on network in modern and future warfare have been increasingly needed. In DoD, LISI has been applied throughout information system life cycle from the planning phase to the development phase to assess the level of interoperability. We also developed SITES which is a tool to assess the level of interoperability in information systems. But we should extend the assessment model from the previous information systems to the weapon systems to assess the level of interoperability including weapon systems as well as information systems. In this paper, we proposed the assessment model of interoperability, implemented the E-SITE based on the proposed model, applied 12 weapon systems and analyzed the experimental result.

미 안보지원역사는 좁은 의미로는 무기와 물품의 지원 및 판매 역사이며, 우리 의지와는 상관없이 세계정세 변화에 따라 국익을 극대화할 수 있도록 변화해 있다. 현 부시 행정부의 안보지원정책은 미래를 위한 "능력에 기초한(Capacity Based)" 모델을 추구하고 있다. 이를 뒷받침하기 위해 기존 NATO 위주에서 구매국 위주 정책으로 변환을 천명하고, 기동성이 떨어지고 유지비용이 많이 드는 무기는 과감히 도태시키고 있다. 이를 추진하기 위해 주요 핵심보직에는 전력기획 및 협상을 주도할 전문가를 보직하고, 대외 군사판매(FMS : Foreign Military Sales)를 자국 경제발전에 적극 활용하고 있다. 이러한 변화의 와중에서 미국은 어떤 특정국가를 챙겨 줄 여유가 없다. 우리 스스로 미국ㄱ의 전략변화와 안보지원관련 법규.제도와 업무수행 절차를 명확히 이해하여 미국의 변화 속에서 민첩히 대응하여 국가이익 차원에서 실리를 추구하는 방향으로 정책이 지향되어야 한다. 미국의 안보지원정책 변화를 정확히 이해하고 지혜롭게 활용함에 따라 국가의 위기가 될 수도 있고 도약의 기회가 될 수도 있다.

우리정부는 경제신장에 의한 국력배양만이 국방력 강화이며 통일에의 첩경이라는 사고아래 경제개발에 주력한 결과, 1961년 1인당 84$ 밖에 안되든 GNP가 1972년에는 302$까지 신장되었다. 그 신장율을 보면 세계 최고선에 이르게 되었을 뿐만 아니라, 금년에는 중.화학공업육성책으로써 80년대 100억불수출, 1,000$소득을 목표로 하는 계획을 작성, 실천에 옮기고 있다. 이에 즈음하여 우리 회원제위께 정부가 그 필요성과 가능성을 어떻게 참작하여 그와 같은 계획을 수립하였는가를 소개함과 아울러 이를 원자재, 자금, 인력, 기술, 동력등 여러면으로 검토, 시행에 있어 주의해야할 점을 열거하고, 그 겨로가에 따라 자본이 적게 소요되고 인력이 대량동원되면서도 부가가치가 높은 기계공업을 육성하고, 또 이에서 만들어진 기계로 공장을 건설한다음, 원자재와 소비재생산을 개발에 나가는것이 유리할 것이라는 판단을 내림과 동시에 정부기획안 가운데 전기공업이 너무나 소홀히 되어있다고 판단되어 이 중요성을 강조하게 되었다.

Since the weapon system project has a large ripple effect on the country by investing a huge budget, analysis of acquisition methods that secured economic feasibility is required in the planning stage to promote the weapon acquisition project. In response to this demand, economic analysis for acquisition method is preformed in the research stage of previous studies, but the analysis on economic analysis for acquisition alternative is imperfect at the present. In this research, we identify the limitations of the effect analysis and propose an additional cost-benefit analysis method to analyze the economic feasibility of the acquisition alternative. It is possible to present the universal results of economic feasibility analysis for not only multiple alternatives but also single alternatives by presenting benefit/cost ratio. It is applied to research on acquisition project of OO guided rocket, and the result of economic analysis for each alternative is presented.

It is an important role of a researcher to preserve the research process and results as a record in the overall R&D from the planning stage to completion. This can be used as a basis to support the objectivity of the R&D process and results. This can be used as a basis to support the objectivity of the R&D process and results. The necessity of writing research notes is raised in terms of research ethics, records management, intellectual property rights protection, and research results protection according to 「National Research And Development Innovation Act」. Therefore, in this paper, the results of the systematic and practical management method of research notebooks operated by government-funded institutions are described.

In order to prepare against the unpredictable provocation of nK on NWI, instead of the threat based force enhancement, sufficient capability based force planning is required in consideration to enemy capability, operations environment, and technological development. This thesis proposes a method on how to prioritize the required capabilities of NWI during the process of identifying capabilities and investing on the decided acquisition assets. Ambiguity in deciding the priority is eliminated and detailed planning is possible through instituting relationship of organization, operation and capability, and by designating weight based on the above relationship. This method identify the various operations and required capabilities, classify the order of priority clearly for NWI, when compare to other method of priority decision. Although capability based force planning requires more assets and faces limitations due to budget, this method will provide and efficient decision making procedure through precise prioritization.

LVC(Live-Virtual-Constructive) training system is drawing attention due to changes in battlefield situation and the development of advanced information and communication technologies. The ROKAF(Republic of Korea Air Force) plans to construct LVC training system capable of scientific training. This paper analyzes the results of V-C interoperability test with three fighter simulators as virtual systems and a theater-level wargame model as a constructive system. The F-15K, KF-16, and FA-50 fighter simulators, which have different interoperable methods, were converted into a standard for simulation interoperability. Using the integrated field environment simulator, the fighter simulators established a mutually interoperable environment. In addition, the Changgong model, which is the representative training model of the Air Force, was converted to the standard for simulation interoperability, and the integrated model was implemented with optimized interoperability performance. Throughput experiments, It was confirmed that the fighter simulators and the war game model of the ROKAF could be interoperable with each other. The results of this study are expected to be a good reference for the future study of the ROKAF LVC training system.
