Every country of the world have made their desirable future by improving the methodology of technology forecasting with priority, selection and concentration, despite the limited budget. About 20 years have passed since Defense S&T forecasting has been initiated but supplier-centered technology forecasting has caused the lack of usefulness for the customers. Therefore, we will search and offer technologies that customers need, based on the methodology of technology foresight that has started in England. It is a real value of Defense S&T forecasting that will help our nation, a smaller and weaker country compared to our neighboring countries, has a secure future and prosperity. For this consideration, 8 directions of the development for Defense S&T forecasting are suggested.

Global Positioning System(hereafter; GPS) is recently an essential element in the various navigation and weapon delivery systems of military aircraft. However, GPS is vulnerable to the jamming threats since its signal power is very weak. Therefore, ROK defense has been concerning how to resolve this issue and how to integrate these systems needed, and is trying to acquire the proper anti-jamming GPS system. This study is to provide several schemes against the jamming threats effectively. We propose the several processes to analyze the required capability and demonstrate the result's of modeling and simulations(hereafter; M&S) for this integration of military aircraft, and the mathematical programming model for system optimization of military aircraft anti-jamming GPS system on the basis analysis of M&S results which could be considered available budget and the project characteristic. These schemes will be helpful on proper acquisition of these systems and. We are looking forward to contributing to the integration of anti-jamming GPS system of ROK military aircraft.

The existing CSP systems is inefficient and brings about waste of budget in some operating aspects which show accumulation of unnecessary items, omitted or running short items and limitation of timely use of them. The purpose of this study is to analyze the actual situation of existing CSP(calculation and estimation of CSP requirements), and to suggest a few methods (post control system by activating buy-back system, and middle and long term operating system itself in relation to budget) to improve the CSP operating systems in order to maximize the effectiveness of combat strength and to contribute to the economic efficiency of defense management. The results show that improved method is efficient and effective by comparing with some actual data.

The Cost has been much emphasized in inside of an army because of the promotion of reconciliation atmosphere between South and North Korea and the reduction of defense budget since 1990. So we are now faced with the problem that we should consider a cost above all besides the performance and arrangement for such a restriction of budget in time of developing new generation weapon systems. In this research we are suggested following two methodologies. One is the develop a weapon system with optimum cost considering a Life Cycle Cost from the first stage of design and the other is the cost control and management with the establishment of Target cost.

The Ministry of National Defense has developed MND-AF and Defense-CBD methodology to make the integration and management of standardization effective through enhancing the interoperability and reusability of information systems. Yet no explicit guidelines or procedures have not been developed for the applying range and mutual relationship of the artifacts between MND-AF and Defense-CBD methodology. Thus, the development time is unnecessarily extended and budget also is increasing because both methodologies produce the artifacts respectively. This paper presents a reusability enhancement scheme for producing MND-AF artifacts according to Defense-CBD process by analyzing artifacts of two methodology les at each element level, so that it will reduce the overhead of producing the artifacts and enhance the completeness of the artifacts. In result, in the case of applying Defense-CBD methodology for developing a information system34 artifacts out of 37 MND-AF artifacts can be reusable.

So far, the main threat to South Korea was North Korea. That is why South Korea established a strategy based on the threat of North Korea and most of the budget on defense was used to deter North Korea. Even though the neighboring countries(China, Japan, and Russia) are growing as a real threat with abilities and intentions based on their powerful naval forces, South Korea has not yet been able to establish a strategy that regards neighboring countries as a threat. But the decades-old structural mechanism of the Korean security environment is undergoing a radical change on April 27, 2018, through the South-North summit and the Panmunjom Declaration. Under the changing security environment, South Korea was placed in a complicated dilemma that had to deal with threats of two axes(China), three axes(China, Japan), and four axes(Japan, Russia). If the one axis threat(North Korea) is dominated by land threats, the second, third and fourth axis threats are threats from the sea. This paper analyzed the maritime strategy of Korea within the framework of maritime-geopolitics, in other words recognition and expansion of the sphere of maritime. I have designed that the maritime defense space that we can deny from threats is divided into three lines of defense: 1 line (radius 3,000km), 2 lines (2,000km), and 3 lines (1,000km). The three defense zones of the three lines were defined as an active defense(1 line), defensive offense(2 line), active offense(3 line). The three defense zones of the three lines were defined as the sphere of core maritime, As a power to deny the sphere of core maritime, it was analyzed as a maneuvering unit, a nuclear-powered submarine, the establishment of missile strategy, and the fortification of islands station. The marine strategy of South Korea with these concepts and means was defined as 'Offensive Maritime Denial Strategy'.

Reliability evaluation of One-Shot system which flies at speed of Mach must be evaluated as the result of many firing tests. But many firing tests are impossible because of budget deficit. Consequently the reliability prediction which substitutes firing tests is used. The accuracy of reliability prediction is decided according to a quantity of accumulated test data. If the test data is insufficient, the direction of prediction can not be set. So we propose the reliability prediction method which applies MIL-HDBK-217 Plus. MIL-HDBK-217 Plus is described about reliability prediction method without sufficient test data. So we apply MIL-HDBK-217 Plus to the rocket motor system, and we accomplish a modeling and a reliability prediction about the system.

Recently, request far application of advanced commercial technology to the defense acquisition process, to reduce the budget and shorten development time, has been increased. To accomplish these goals, the Advanced Concept Technology Demonstration(ACTD) is used for the defense acquisition process in Korea. And User Utility Assessment is tested to make a decision for transition to acquisition process. But this process does not include measurement of technology maturity and impacts of interface and interaction among the technologies. In this research, we propose the needs of measurement of TRL and IRL and application of SRL to reduce the risk during development phase, to understand the relations of technologies, and to fulfill the requirement far transition of the ACTD project to system development and demonstration process.

Impatience characteristics are an important factor to be considered in the defense field, which is sensitive to time, but there are not many cases applied. In addition, due to the difficulty of analysis that must consider various probabilistic factors (breakdown/maintenance distribution, impatience characteristics, etc.), military decision makers consider only simple data (number of occurrences per year, maintenance time, etc.) Therefore, in this study, a model capable of analyzing the performance of the emergency maintenance system for determining the appropriate size and organization of military and civilian maintenance personnel was presented in consideration of impatience characteristics and probabilistic factors. And through numerical analysis, the appropriate size of the military and civilian emergency maintenance teams was analyzed. This study is significant in that it can improve readiness of operational power and prevent waste of defense budget through efficient operation of the military's emergency maintenance system.
