The Gun-Oreinted Anti-Air Warfare(GOAAW) which is still one of the important weapon systems of the vessel like the patrol killer to confront air threats comprises the components of the combat system - Command & Control(C2), Ballistic Calculation Unit, Sensors and Guns. In this paper, the GOAAW process of the patrol killer combat system is analyzed with probability and simulated to evaluate the effectiveness and capability of the GOAAW. As a result of the simulation, the performance measures of the GOAAW are discussed in the functional and operational aspects of the combat system.

This paper proposes a novel process which can develop the system requirements in defense R&D programs. As the weapon systems become more complicated, the success and effectiveness of R&D outcome heavily depend on the application and tailoring of systems engineering process and methods. And, the accuracy and quality of system requirements are essential prerequisite to leverage the systems engineering process. To produce the artifacts of systems engineering such as OCD, ORD, and the systems requirements, the system user can write out requirement document using the proposed implementation process and templates without expending heavy work loads.

Underwater radiated noise is an important characteristic in the naval weapon systems. It is difficult to measure the radiation efficiency of underwater vehicle, such as UUV(unmanned underwater vehicle) and underwater weapons in real operation environment. In this study, acoustic radiation efficiency of a circular cylindrical structure is measured in the laboratory-water tank. The radiation efficiency is compared with the numerical results and it is found that they are in a good agreement. Therefore, the measurement method can be applied effectively for predicting the underwater radiation noise and effectiveness of radiation reduction means.

최근 전장환경의 급격한 변화와 고도화된 과학기술로 인해 무기체계의 성능은 매우 발전되었으며 세계 각국은 고성능, 고효율의 최신 무기체계 개발에 역량을 집중하고 있다. 개별 무기체계에 대응하여 새롭게 개발된 무기체계는 기존 무기체계에 대한 패러다임을 뛰어넘어 새로운 개념과 운용방식을 요구하고 있다. 무기체계의 효과를 규명하고 검증하기 위한 수단으로 가장 적합한 것은 실제전장에 무기체계를 투입한 실기동 실험을 통해 효과를 분석하는 것이다. 그러나 무기체계 효과분석을 위해 실기동훈련을 계획하고 실시하는 것은 비용 뿐 아니라 군사력 동원면에 있어서 비효율적이고 부담이 높은 단점이 있으므로, 국방시뮬레이션 기술을 활용하여 저비용 고효율의 모의분석을 실시함으로써 계량적인 효과분석을 수행하고 수치화된 판단 근거를 제공하는 것이 보다 바람직하다고 할 수 있다. 본 고는 대대급 이하 소부대의 전장상황에서 지상군 단위무기체계의 효과 분석을 수행할 수 있는 국방 시뮬레이션 모형의 개발 방향을 제시한다.

향후 한국군의 전력발전을 위해 미래전 무기체계엔 대한 획득소요가 활발히 제기되고 있으며, 소요에 부응하기 위한 무기체계 효과분석이 요구되고 있다. 국내외적으로 이와 같은 미래전 무기체계 소요검증 및 효과분석을 위해 전투실험이 수행되고 있다. 현재 미래전 무기체계 분석수단으로 가상자료를 활용한 시뮬레이션이 널리 활용되고 있으며, 시뮬레이션을 활용한 전투실험은 향후 개발될 무기체계의 특성자료를 기준으로 실제 전장환경과 동일한 조건에서의 시뮬레이션을 통해, 각 무기체계의 효과를 정량적으로 분석할 수 있기 때문이다. 본 연구는 이와 같은 미래전 무기체계 효과분석시 활용될 수 있는 시뮬레이션 모형 활용기법을 제안하여 전투실험의 효과를 검증하고, 한국군의 미래 모의분석체계 발전에 기여하고자 한다.

Many different kinds of wargame models have been developed and used in training and analysis purpose. However, there has been few wargame model which analyze corps or division level operational analysis. Recently KIDA develops corps level operational analysis model based on START(simplified tool for analysis of regional treats) model developed by RAND. This model runs in a PC level with 2MB memory and provides one day combat results within 30 seconds. Only one or three person can operate this model and evaluate multiple corps level operational analysis including chemical effects, $C^3I$ capacity, new weapon system effectiveness and other qualitative effects. We tested this model and evaluated input and output data. We showed that this model can be applied in division level operational analysis also. As an example division level application procedure and sensitivity analysis data was provided. We also find some limitation and problems in the model and suggest application areas and improving methods.

Armed aircraft of a basic trainer class installs external stores under wing box by using pylon and performs an operation such as weapon delivery and jettison, and should be designed to withstand all kinds of loads applied to external stores. The static strength test of pylons and wing box was performed to assess the static strength of pylon and their support structures for substantiation. Based on the test, the structures were verified to fully satisfy a given design requirement. In this paper, methods of test load generation of wing box and pylon, evaluation of test result data and design result of test set-up were presented. Comparing the FEM analysis with the same test data can lead to good match and reasonable deviation between both. Finally, based on the test and the analysis, the static strength of test article was substantiated and the reliability and effectiveness of analysis math model were obtained.

This research studies an attrition rate considering terrain feature in a battlefield. Lanchester-type combat models for heterogeneous forces and the Weapon Effectiveness Index are used in this study. The various environments of the battlefield can be explained by the terrain feature. Attrition rates of heterogeneous model are estimated by applying the battle of Baek-Sek mountain during the Korean War. Estimated attrition rates are checked by the paired samples T-Test. Specific cases are shown in this paper as an example. If we study out the relative influence of the terrain feature upon the performance of individual weapons, these will be a possible alternative to analyze the military operations.

In this paper, we proposed verification methods to prove the effectiveness of automatic test equipment (ATE) for weapon systems. Since the test results from the unproven ATE is not reliable and its use is limited as objective data, it is essential to verify the test equipment in order to guarantee the quality level of the unit under test (UUT). Through the suggested methods, it is applied to the ATE of the tactical information communications network (TICN) system to confirm the verification results and to describe the validation results.

The survivability of a naval ship is the ability of the ship and its onboard systems to remain functional and continue a designated mission in man-made hostile environments. A passive decoy system is primarily used as a weapon system for improving the survivability of a naval ship. In this study, an engagement scenario-based simulation program was developed for decoy effectiveness assessments against an anti-ship missile (ASM), which tracks a target with sea-skimming and active radar homing. The program can explain the characteristics of a target ship, such as the radar cross section and evasive maneuvers, as well as the operational performance of the onboard decoy system, the guidance method of the ASM, and the engagement environment's wind speed and direction. This paper describes the theory and formulations, configuration, and user interface of the developed program. Numerical examples of a decoy effect assessment of a virtual naval ship against an ASM are presented.
