In government procurement programs, cost estimation and analysis support funding decisions and are the basis for other major decisions, too. Such estimating and analyzing the cost of the weapon systems are crucial in execution of the defense budget. However, existing cost estimations and analyses have focused on domestic R&D projects, thus those are not valid in application to foreign weapon acquisitions. This study aims at foreign weapon systems that are acquired from Direct Commercial Sales. Because the data for price estimation of a foreign weapon is usually not available, we suggest a price estimation model based on performance factors of the weapon. In this study, the proper price of the weapon system is estimated using the parametric cost estimating model. Using the data of helicopter-launched anti-tank guided missiles worldwide, we analyze the effect of each performance factor on the weapon system price by regression analysis, and use step-wise and ridge regression analysis to remove multi-collinearity. This study hopefully contributes to more reasonable decision making on proper price of weapons.

최근 국방부는 무기체계를 사이버보안의 영역에서 무기체계를 포함하였다. 기존 정보화영역에 한정되었던 사이버보안의 대상에서 확대되고 진화된 개념이 적용되었다. 무기체계는 소프트웨어의 비중이 점차 늘어나고 있고, 사이버위협의 대상임에는 분명하다. 따라서, 사이버보안 측면에서 무기체계 수명주기간 문제점을 진단하여 무기체계 사이버보안 발전방향을 제시하고자 한다. 무기체계 사이버보안 발전을 위해서는 무기체계 소프트웨어 관리제도를 포함하여 종합적인 정책수립이 이루어져야 하고, 이와 관련된 이해관계자들의 적극적인 참여가 필요하다.

Weapon target assignment problem is an essential technology for automating the operator's rapid decision-making support in a battlefield situation. Weapon target assignment problem is a kind of the optimization problem that can build up an objective function by maximizing the number of threat target destructed or maximizing the survival rate of the protected assets. Weapon target assignment problem is known as the NP-Complete, and various studies have been conducted on it. Among them, a greedy heuristic algorithm which guarantees (1-1/e) approximation has been considered a very practical method in order to enhance the applicability of the real weapon system. In this paper, we formulated the weapon target assignment problem for supporting decision-making at the level of artillery. The lazy strategy based on hierarchical structure is proposed to accelerate the greedy algorithm. By experimental results, we show that our algorithm is more efficient in processing time and support the same level of the objective function value with the basic greedy algorithm.

무장정확도는 무기체계 획득의 기본 지표가 되는 성능으로 이에 대한 정확한 개념 정립과 시험평가 방법의 설정이 요구된다. 기존의 항공무장의 정확도 시험평가 방법은 무장의 탄착형태를 정확하게 고려하지 않았다. 본 연구는 확률 및 통계기법을 이용하여 최적 CEP 계산법과 각 시험평가 단계별 평가방안을 제시하였다. 먼저, 알려진 여러 무장정확도 계산법 중 항공무장의 탄착형태를 반영하는 최적 CEP 계산법으로 록히드마틴 CEP법과 존슨 CEP법을 추천하며, 시험평가 단계별 최적의 시험평가 방법을 제시하였다. 본 연구결과는 항공무장의 정확도 평가에 유용하게 사용될 수 있을 것이다.

Purpose: Recent weapon systems in defense have increased the complexity and importance of software when developing multifunctional equipment. In this study, we analyze the accuracy of the proposed software reliability model when applied to weapon systems. Methods: Determine the similarity between software reliability analysis results (prediction/estimation) utilizing data from developing weapon systems and system failures data during operation of weapon systems. Results: In case of a software reliability prediction model, the predicted failure rate was higher than the actual failure rate, and the estimation model was consistent with actual failure history data. Conclusion: The software prediction model needs to adjust the variables that are appropriate for the domestic weapon system environment. As the reliability of software is increasingly important in the defense industry, continuous efforts are needed to ensure accurate reliability analysis in the development of weapon systems.

The Network-Centric warfare over weapon data link networks has been developed for the recent decade. Since the US navy had begun to develop tactical digital information chain, it has gradually transformed into weapon data link technology. As data link network system and its protocol have been advanced into high-technology, focusing and targeting on moving targets become possible in net-enabled environments. However, it is difficult to identify the primary information from numerous battlefields and understanding approaches to damage a target in a timely manner. In this paper, to better understand the targeting assessment, we suggest a specific solution: Bomb Hit Indication(BHI) using information in weapon data link messages. In order to prove our suggestion, we implement the BHI solution and apply it into the weapon data link integrating system.

스마트무장은 종말 유도조종을 통해 정밀타격 임무를 수행하는 초소형 유도무기로 미래 전장환경의 신무기체계이다. 하지만 크기로 인한 구조적 제한으로 인해 압전구동 방식의 조종날개를 이용해 제어를 수행하기 때문에 기동력이 작아 유도범위가 제한적이다. 본 논문에서는 스마트무장의 효과도를 높이기 위한 비 표준조건 사격제원 산출 알고리즘을 제안한다. 제안된 알고리즘은 획득한 전장환경 정보를 이용해 표준조건에서의 사격제원을 보정해 비 표준조건의 사격제원을 산출한다. 다양한 조건에서의 수치 시뮬레이션을 통해 제안된 알고리즘의 성능을 검증하였다.

In this paper, we have proposed hardware and software architecture of a launch control unit for the compatibility between air defense weapon systems loaded on shipboard. Until now, there is no compatibility between weapon systems loaded in battleships of korean navy. In the case of HaeGung system recently completed the test and evaluations, although it will be deployed on several kinds of shipboards, it has no compatibility and flexibility with other air defense weapon systems. Recently it reports that a long range air defense weapon system will be carried on future korean destroyer KDDX. Because the HaeGung and a long range air defense system will be operated together in KDDX, it is necessary to provide the compatibility between two weapon systems. So we have proposed architecture to provide the compatibility of the launch control unit that controls the launching system and the missile interface unit, and the missile in each weapon systems.

교전 초기에 높은 위협도를 가진 다수의 표적에 대해 적을 신속하게 제압하기 위해서는 단 시간 내에 가능한 많은 무장을 발사할 수 있도록 적시에 효과적인 무장 할당을 수립하여 교전 효과를 극대화하는 것이 중요하다. 본 논문에서는 다표적 다무장 환경에서 신속 대응 무기 체계를 위한 무장 할당 알고리즘을 제안한다. 제안하는 알고리즘에서는 무장군 별 방위각 크기 기준으로 표적을 정렬하여 방위각 기준으로 표적군-무장군 간 집단 할당을 수행한 후, 산출된 표적의 위협도 기준으로 표적-무장 간 개별 할당을 수행하여 복잡도 낮은 연산으로 신속 대응이 가능한 사격 계획을 수립하여 교전 효과를 극대화한다. 본 논문에서는 제안하는 알고리즘의 시뮬레이션 및 가시화를 통해 성능 평가 및 검증을 수행하였다. 성능 평가 결과, 제안하는 알고리즘은 대규모의 전장 환경에서도 빠른 시간 내에 높은 표적 할당률을 보이는 효과적인 무장할당을 수행함으로써 신속 발사 무기 체계에 적용할 시에 높은 효용성 및 효과가 기대된다.

A missile defense system is composed of radars detecting incoming missiles aiming at defense assets, command control units making the decisions on weapon target assignment, and artillery batteries firing of defensive weapons to the incoming missiles. Although, the technology behind the development of radars and weapons is very important, effective assignment of the weapons against missile threats is much more crucial. When incoming missile targets toward valuable assets in the defense area are detected, the asset-based weapon target assignment model addresses the issue of weapon assignment to these missiles so as to maximize the total value of surviving assets threatened by them. In this paper, we present a model for an asset-based weapon assignment problem with shoot-look-shoot engagement policy and fixed set-up time between each anti-missile launch from each defense unit. Then, we show detailed linear approximation process for nonlinear portions of the model and propose final linear approximation model. After that, the proposed model is applied to several ballistic missile defense scenarios. In each defense scenario, the number of incoming missiles, the speed and the position of each missile, the number of defense artillery battery, the number of anti-missile in each artillery battery, single shot kill probability of each weapon to each target, value of assets, the air defense coverage are given. After running lpSolveAPI package of R language with the given data in each scenario in a personal computer, we summarize its weapon target assignment results specified with launch order time for each artillery battery. We also show computer processing time to get the result for each scenario.
