In this paper, air-defense simulation model, called "DADSim", will be introduced. DADSim(Distributed Air Defense Simulation Model) was developed by Modeling&Simulation Lab of K.N.D.U.(Korea National Defence Univ) Weapon Systems Department. This model is an analysis-purpose model in the engagement-level. DADSim can simulate not only the global air-defense or Korean Peninsula but also the local air-defense or a battle field. DADSim uses the DTED(digital terrain elevation data) LeveII it for the representation of peninsula terrain characteristics. The weapon systems cooperated in the model are low/medium-range missile systems such as HAWK, NIKE, SAM. DADSim was designed in the way of object-oriented development method, implemented by C++ language. The simulation view is an event-sequenced object-orientation. For the convenience of input, output analysis, GUI(Graphic User Interface) of menu, window, dialog box, etc. are provided to the user, For the execution of DADSim, Silicon Graphic IRIX 6.3 or high version is required. DADSim can be used for the effectiveness analysis of­defence systems. Some illustrative examples will be shown in this paper.

Submarines are weapons systems that have been proven to be useful in battle since World War I and have continued to improve the efficiency of propulsion systems in order to be used efficiently on the battlefield. In particular, countries that unable to utilize nuclear propulsion systems make efforts to increase the efficiency of Air Independent Propulsion systems, and typical examples are fuel cells, Stirling engines and MESMA. It is also expected that the development of new propulsion systems such as hydrogen-reformer fuel cells, metal-air fuel cell and direct combustion propulsion systems will continue, so the characteristics of these will be examined and the performance based on the published data be checked in this thesis.

This paper considers the allocation and engagement scheduling of air defense missiles by using MIP (mixed integer programming). Specifically, it focuses on developing a realistic MIP model for a real battle situation where multiple enemy missiles are headed toward valuable defended assets and there exist multiple air defense missiles to counteract the threats. In addition to the conventional objective such as the minimization of surviving target value, the maximization of total intercept altitude is introduced as a new objective. The intercept altitude of incoming missiles is important in order to minimize damages from debris of the intercepted missiles and moreover it can be critical if the enemy warhead contains an atomic or chemical bomb. The concept of so called the time window is used to model the engagement situation and a continuous time is assumed for flying times of the both missiles. Lastly, the model is extended to simulate the situation where the guidance radar, which guides a defense missile to its target, has the maximum guidance capacity. The initial mathematical model developed contains several non-linear constraints and a non-linear objective function. Hence, the linearization of those terms is performed before it is solved by a commercially available software. Then to thoroughly examine the MIP model, the model is empirically evaluated with several test problems. Specifically, the models with different objective functions are compared and several battle scenarios are generated to evaluate performance of the models including the extended one. The results indicate that the new model consistently presents better and more realistic results than the compared models.

As observed in the recent war, suppression of enemy air defense operation is one of the major tactics, simultaneously conducted with high payoff target. Specifically, our air defense operation should be properly constructed, since the operating environment of our forces mostly consists with mountainous terrain, which makes detections of the enemy difficult. The effective arrangements of low altitude air defense radars can be suggested as a way of improving the detection capability of our forces. In this paper, we consider the location problem of low altitude air defense radar, and formulate it as an Integer Programming. Specifically, we surveyed the previous researches on facility location problems and applied two particularly relevant models(MCLP, MEXCLP) to our problem. The terrain factor was represented as demand points in the models. We verified the optimal radar locations for operational situations through simulation model which depicts simple battle field. In the simulation model, the performance of optimal radar locations are measured by the enemy detection rate. With a series of experiments, we may conclude that when locating low altitude air defense radars, it is important to consider the detection probability of radar. We expect that this finding may be helpful to make a more effective air defense plan.

The Military Tactical Communication technology for effective network-centric warfare is developing. Targeting broadband wireless transmission, core technology for connection, and Transmission technology that secure survivability under High-speed Movement environment. On the one hand, Tactical data communication system that reflects military characteristic is developing on the base of Legacy communication equipment which is used in the field. Because almost every military units in the field have used voice to communicate which lower efficiency of operation, they have made effort to Substitute voice communication which delays military Operation Tempo to digital communication. The Communications environment of troops in Forward edge of battle field area is very poor. Especially in terms of limited frequency allocation and bandwidth. Therefore, improving the efficiency of frequency is essential for Military Tactical Communication. This paper is about The Data Compression Method for increase of Efficiency in Tactical Data Communication over Legacy Radios which are UHF, VHF, HF Radio. I proposed and proved the most efficient Data Compression Method that reflects military characteristic, after analyzing the experimentation, which simulate CAS(Close Air Support mission) data transmission between Pilot and TACP.

This article is focused how the maritime strategy between continental powered country(the Soviet, the China) and maritime powered country(the U.S.) interact with attack and defense theory. We will know, what is the maritime strategy that the U.S. of military superiority has pursued with the point of view of attack, on the other hand, relatively what is the maritime strategy that the Soviet-Sino of military inferiority has pursued with the point of view of defense. In cold war, the Soviet has counteracted to 'blue belt defense' in active defense as to the U.S. 'sea strike' and in post cold war, the China counteract to 'A2/AD' as to the U.S. 'Air-Sea Battle'. The difference between the Soviet-Sino maritime strategy is that the China has emerged the second an economic power and their leadership has a strong's will to strengthen their navy's power. although the U.S. declare the pivot to Asia, the influence on Asia of the U.S. tend to decrease because of sequest. therefore, the China will seek to the more active defense beyond the first island chain. Meanwhile, the U.S. has reinforced of 'hub and spoke strategy' to solidify the U.S. formal allies to band together regional powers and to overcome the A2/AD challenge, the U.S. has been developed that the Air-Sea Battle concept meshes with Washington's 'rebalancing' policy toward the Asia-Pacific as its vital missions to safeguard core island or semi-island allies-namely, Korea and Japan-and crucial sea lanes of communication in the region are conducted mostly from or over the sea.

본 연구는 첨단과학 기술이 전투개념에 미치는 영향과 AICBM 기술을 접목한 미래 육군의 전투를 새롭게 개념화 하는데 목적이 있다. '전투개념'은 시대 상황에 따라 변화하고, 다음 두 가지 사례를 통해 볼 수 있다. 첫째, 적을 분석 하여 상대적 우위를 달성하는 개념이다. 이러한 대표적인 사례가 미군이 '공지합동전투'를 '다영역작전(Multi-Domain Operations)'으로 발전시킨 경우를 들 수 있다. 둘째, 전투개념의 변화를 이끄는 '과학기술'이다. 세계 1차 대전시 육상과 해상에서의 화력전이 항공기의 출현으로 인해 세계 2차 대전에서 '공중전'으로 발전된 것이 대표적 사례이다. 이와 관련하여 미군은 '미래사령부' 창설 등을 통해 첨단과학기술을 기반으로 미래 작전환경에 부합한 싸우는 개념과 미래 군 건설에 집중하고 있다. 따라서 우리 군도 4차 산업혁명의 주요기술을 기회로 활용하여 미래 전투개념을 발전시킬 필요가 있으며, 미래의 전쟁은 첨단과학기술이 전쟁을 수행하는 개념 발전에 영향을 크게 미칠 것이며, 이는 4차 산업혁명을 근간으로 한 AICBM 기술이 초연결·초지능·초융합의 형태로 국방운영에서의 혁신을 촉진할 것이기 때문이다. 따라서 본 연구는 첨단과학 기술이 전투개념에 미치는 영향과 AICBM 기술을 접목한 미래 육군의 전투개념을 제시할 것이다.

2014년 돈바스 분쟁과 2022년 우크라이나-러시아 전쟁 사례를 통해 제공권은 더 이상 공군에 의해서만 확보할 수 있는 것이 아님을 경험하고 있다. 기존의 공군이 수행하던 원거리 감시정찰과 타격은 드론과 미사일로 대체할 수 있으며 적의 공중공격은 판치르와 휴대형 대공미사일 같은 방공무기체계로 국지제공권을 장악하여 지상군의 자유로운 기동 작전을 수행할 수 있다. 즉, 지금처럼 공군과 해군이 원거리 작전을 통해 제공권을 장악하는 것이 훨씬 유리하며 지상군은 이들을 지원해주는 작전개념이 더욱 적절하다. 따라서 본 연구는 이러한 제공권 작전 수행체계에 대해 값비싼 전투기에 집중하기보다 비용 대 효과성 측면을 고려하여 방공무기체계, 드론, 미사일, 정밀유도 포탄 등을 병행 발전시켜 적의 공중공격에 신속히 역공할 수 있도록 제공권 작전 수행체계에 대한 시사점을 제공하는 것이다.
