A HILS(Hardware-In-the-Loop Simulation) technique for an IR guided weapon is proposed. The IR HILS facility functions as a testing unit for a missile guidance and control system to evaluate target acquisition, tracking, and countermeasure performance. The configuration of IR HILS facility, modeling technique of an IR environment including target, background and countermeasure, and test and evaluation procedure are included.

Maintenance equipments, tools, manuals and documents are needed to maintain the weapon systems. At the time, a lot of technical materials are maintained and used individually at a various places and organizations. Thus, maintenance engineers can not get the necessary informations quickly and the efficiency of maintenance was low. In this paper, first we analyze the maintenance processes in weapon systems and define the total measure to evaluate the maintenance efficiency of weapon systems. Second, we propose a implementation procedure to integrated maintenance system.

To obtain the requirements of capability and analyze mission loads for weapon systems which are in process of development, Operational Mode Summary/Mission Profile(OMS/MP) should be documented in advance. In this paper, we have proposed a systematic and practical OMS/MP model processes of a weapon mounted combat vehicle for analyzing power and energy strategy. The wartime and peacetime OMS/MP of a hybrid wheeled combat vehicle which is mounted with an anti-tank guided weapon(ATGW) is also presented as its application.

Recently, the increased use of anti-ship guided missiles, a weapon system that detects and attacks targets in naval engagement, has come to pose a major threat to the survivability of ships. In order to improve the survivability of ships in response to such anti-ship guided missiles, many studies of means to counteract them have been conducted in militarily advanced countries. The integrated survivability of a ship can be largely divided into susceptibility, vulnerability, and recoverability, and is expressed as the conditional probability, if the ship is hit, of damage and recovery. However, as research on susceptibility is a major military secret of each country, access to it is very limited and there are few publicly available data. Therefore, in this study, a possibility of estimating the susceptibility of ships using an anti-air defense system corresponding to anti-ship guided missiles was reviewed. To this, scenarios during engagement, weapon systems mounted to counter threats, and maximum detection/battle range according to the operational situation of the defense weapon system were defined. In addition, the effectiveness of the anti-air defense system and susceptibility was calculated based on the performance of the weapon system, the crew's ability to operate the weapon system, and the detection probability of the detection/defense system. To evaluate the susceptibility estimation feasibility, the sensitivity of the detailed variables was reviewed, and the usefulness of the established process was confirmed through sensitivity analysis.

High-Level Architecture(HLA)/Run-Time Infrastructure(RTI) are standards for distributed simulation systems and offer a technology to interconnect them and form one single simulation system. In defense domain, M&S is the only way to prove effectiveness of weapon systems except for Live Fire Testing (LFT). This paper focuses on guided missile simulations in weapon systems for engagement analyses and proposes the integrated flying vehicle model that is based on HLA/RTI. There are a lot of missiles in real world; therefore, we should develop each missile models in M&S in order to apply battlefield scenarios. To deal with the difficulties, in this paper, firstly, I classify these missiles into three models: ballastic, cruise, and surface-to-air missile models, and then I design each missile model and integrates them into a single model. This paper also offers a case study with my integrated flying vehicle model. At the conclusion, this paper presents contributions of this paper.

The private sector is currently reviewing the feasibility of the project or deciding economic policies by analyzing the economic ripple effects. However, the arms acquisition project focuses on the need for the national defense weapons system by analyzing the costs and the effectiveness of the analysis and reviewing the necessity and feasibility of the project. In order to analyze the economic ripple effects, KB (the Bank of Korea) prepares and publishes an analysis table of industrial associations in a given unit. IAAR (the industrial association analysis report) is difficult to apply directly to the defense weapons system. Therefore, research on the economic ripple effects applicable to the defense arms procurement project was needed. In this study, we propose the generic methodology for estimating economical and technical ripple effects resulted in acquiring new weapon systems. Based on the analysis of inter-industrial relations, economical ripple effects are estimated with production inducing effects, value-induced effects, employment-induced effects and export-induced effects. Also, the technological ripple effects are estimated with technological intensity represented by investment cost in research and development. To show the validity of proposed methodology, a case study of acquiring new weapon systems such as GR (guided rocket), destroyer, and helicopter is accomplished. From the case study, it is concluded that these economical & technological ripple effects can be used as a reference to decision making in the course of acquiring major future defense weapons systems.

The development of a guided weapon system, such as a tactical missile, requires a performance analysis of a nonlinear system. Generally, the Monte Carlo analysis method is used for this purpose. The limitation of this method, a large number of simulations, for a nonlinear system performance analysis strongly motivated the development of a more efficient analytic technique. In this paper, the statisfical linearization methods is used for the performance analysis to the guided weapon system with the help of covariance analysis technique. Because the statistical linearization methods cannot be used to the look-up table nonlinear form such as aerodynamic coefficients, the second order polynomial representations is obtained from the table using the Lagrange interpolating polynomial and linearized statistically. Simple simulations about initial state conditions and random component in guidance command shows the results of this technique.

무기체계에 첨단기술이 접목되고 연구개발에 많은 비용이 듦으로써 소요군은 수명주기 전 단계에서 무기체계의 높은 신뢰도를 요구하고 있다. 하지만 국방 무기체계의 신뢰도에 대한 연구는 관심 부족 또는 자료수집의 제한으로 실증적인 연구가 제한되고 있다. 본 연구에서는 무기체계 운용자인 함정, 작전 및 정비지원 부대를 직접 방문하여 수집한 경험 및 운용자료를 바탕으로 야전운용제원 수집 프로세스를 제안하였다. 또한 해성 유도탄 발사체계의 운용 MTBF를 도출한 후 개발 시 예측값과 비교 분석하여, 예측값 대비 운용값이 저조한 부품들을 식별하였다. 연구결과를 해군 내 정비지원 부대 및 체계 개발업체에 피드백 시 해성 유도무기 발사체계의 정격 성능 유지에 기여할 수 있을 것이다.
