Weapon effect is a key issue throughout the life cycle of weapon systems. Only when weapon effect is considered properly, Effects Based Operation(EBO), Effects Based Acquisition(EBA), and Effects Based Development(EBD) could be possible. Because the transfer of weapon effect technologies is restricted in most foreign counties, independent development is necessary. In this paper, framework of weapon effects calculator for hardened targets is proposed to meet the own development needs. It is designed focusing on running time, validation and expandibility by adoption of modular architecture. Required technologies for each module are identified, and unclassified ones are summarized.

This paper presents global and optimal solution for weapon assignment problems using the Munkres assignment algorithm. We propose a new modeling method of weapon assignment problems concerning some constraints of weapon systems. In this paper, we compares the Munkres weapon assignment algorithm with two other algorithms employing a search tree model in terms of computational complexity and performance. One is an optimal algorithm using exhausted search and the other is a greedy algorithm which selects the first search result as a solution. The experiment results show that the Munkres weapon assignment algorithm has better performance and less computational complexity in comparison with the two other algorithms.

This note suggests three approaches to improve reliability in developing weapon systems. The high complexity of the weapon systems make it hard to analyze and predict of those reliability. Current situations of the reliability have been reviewed in terms of logistics support analysis (LSA), warranty policy, maintenance and development. Three suggestions are notified to improve the reliability considering the complexity of the weapon systems.

Weapon System effectiveness indices are a key factor to the cost-effectiveness analysis in the process of allocating national resources in an optimal fashion. First part of this paper reviews the need of weapon -effectiveness indices, historical development of methodologies on military strength evaluation with various models of indices, and the interrelation-ship between weapon effectiveness indices and war-game. Second part of this paper analyzes the concepts and usage of the already developed methodologies, i .e., index of power, weapon lethality index (W.L.I.), index of fire power potential (I.F.P), fire power potential (F. P. P), and weapon effectiveness indices/weighted unit value (W. E. I/W. U. V.). Finally, weaknesses and limits of these methodologies are compared and evaluated. Result of this research shows that the W. L. I, I. F. P, and F. P. P seem to possess many non-scientific or ambiguous facets, but the W. E. I/W. U. V method produces more detailed, inclusive, and reasonable indices. The paper concludes with the emphasis on the importance of the provision of the theoretical bases to develop effectiveness indices which can be used to evaluate Korean weapon systems, and the early establishment of a specialized research group to manage and develop methodologies on the weapon effectiveness indices.

Various methods have been developed to predict the flight path of an air-launched weapon to intercept a fast-moving target in the air. However, it is also getting more challenging to predict the optimal firing zone and provide it to a pilot in real-time during engagements for advanced weapons having new complicated guidance and thrust control. In this study, a method is proposed to develop an optimized weapon engagement zone by the SCG (Scaled Conjugate Gradient) algorithm to achieve both accurate and fast estimates and provide an optimized launch display to a pilot during combat engagement. SCG algorithm is fully automated, includes no critical user-dependent parameters, and avoids an exhaustive search used repeatedly to determine the appropriate stage and size of machine learning. Compared with real data, this study showed that the development of a machine learning-based weapon aiming algorithm can provide proper output for optimum weapon launch zones that can be used for operational fighters. This study also established a process to develop one of the critical aircraft-weapon integration software, which can be commonly used for aircraft integration of air-launched weapons.

In this paper, we have proposed novel technique to improve maintainability for training vehicle of underwater weapon system. In case of under water weapon, the fire procedure is related with operation of expulsion system in submarines. So the submarine crews should practice the complex fire procedure of weapon system by using training vehicle, which is safer and cheaper than operational weapon. After emitted from submarine, the training vehicle rise to the surface and should be withdrawn from the sea. The recovered training vehicle is transported to maintenance depot and pass through the recycling procedure including disassembling the vehicle, data acquisition & analysis, battery charge, replacing expandable components, testing the captive equipment, and assembling the vehicle. The disassembling & assembling of training vehicle which is composed of watertight section or airframe, is time-consuming work. So in this paper, we have studied the elements of recycling procedure and propose the method to exclude the assembling & disassembling work for maintainability improvement.

The Core in Weapon system R&D is to realize the user required capabilities in limited schedule and cost. Therefore, the design of weapon system focuses to functional design for realization of requirement capabilities. However, the weapon system should not only basically bring the confidence to friendly forces bring fear to enemy forces to maximize the operational effectiveness of weapon systems and we consider the exterior design as the important factor to compete with foreign systems in international defense market besides capabilities and cost. For that reason, we made study case about the visual design decision process applied to the LVT(light tactical vehicle) project which was recent successful deployment among the many R&D projects of auto industry. Based on this case, this study suggests the necessity of the exterior design decision process the maneuver weapon system is developed.

Integrated Logistic Support (ILS) is a management and technical process whereby all the diverse elements needed to fully operate, maintain, and totally support a materiel system in the field are identified, developed, and deployed simultaneously and on an equal priority with the item of materiel being supported. The test and evaluation (T＆E)of ILS act the important role of reduction of life-cycle cost and keeping of good performance for weapon system. In this article, we suggest the alternatives for improvement in the test and evaluation of ILS during weapon system acquisition. It is hoped that this research is valuable and beneficial to persons related weapon system acquisition, in order to maximize the efficiency of defense acquisition management by reducing the life-cycle cost and enhancing the quality of weapon system.

Due to the population of the Republic of Korea is getting less, the shortage of available troops has become a big issue. In response to this, the need for Unmanned weapon systems is rising. To operate an Unmanned weapon system near borderlines or low altitude, it is necessary to protect not only the system itself but also operational information communicated between the Unmanned system and control station, so that they should be safe using Cybersecurity measures. Besides, it is critical to protect a few core technologies applied to Unmanned weapon systems throughout the Anti-Tamper measures. As the precedent studies only focus partially, Cybersecurity or Anti-Tamper, it is acknowledged that comprehensive studies are needed to be conducted. This study is to incorporate both concepts into Korea's defense acquisition process. Specifically, we will outline the concepts and needs of Cybersecurity and Anti-Tamper, and briefly present ways to apply them simultaneously.

Naval combat system is total management system integrating a ship and several weapon system functions. For the mission of a ship, naval combat system manages features and constraints of each weapon system. Proper treats of each weapon system's conditions guarantee effective performances of naval combat system. In this paper, the relationship of anti-air weapon system's on board position and self-defence effectiveness against anti-surface missiles is studied
