      • 러시아의 군사전략: 위협 인식과 군사력 건설 동향

        김규철 ( Kyuchul Kim ) 한국군사학회 2020 군사논단 Vol.100 No.1

        본 논문의 목적은 군사 측면에서 러시아의 생각과 논리를 정확히 읽기 위해 러시아 군사전략의 본질을 규명하는 것이다. 이에 따라 러시아 군사전략 구성요소 중 러시아의 위협인식이 무엇인지 파악하고 그러한 위협에 대응하기 위해 어떻게 군사력을 건설했으며, 유사시에는 어떻게 사용했는지 고찰했다. 러시아 위협인식은 첫째, 크림 합병 이후 더욱 강화된 외국의 대러 압박을 중요한 위협으로 보고 있으며, 이는 강대국 정체성 유지와 관련된다. 둘째, 러시아는 미국 및 NATO를 지대한 위협으로 보고 있으며, 이는 전략균형 유지와 관련된다. 셋째, 미국의 MD, 우주공간 무기화, 글로벌신속타격(PGS) 개념의 현실화는 러시아의 미래전 대비와 관련된 위협이다. 러시아는 위협에 대비하기 위해 병력 충원, 무기 현대화, 주요 전략방향 전투준비, 실전적 훈련 등으로 군사력을 증강하였다. 또한, 크림반도 합병, 시리아 대테러작전 개입 간 실제 군사력 운용 사례를 분석한 결과 강대국 정체성, 전략균형, 미래전 대비 등 3개 요인이 작용한 것을 알 수 있었다. 이와 같은 러시아 군사전략을 고려하여 한국의 군사안보를 위해 전쟁억제 방법, 위협 대응 위주 군사력 건설, 군사협력 확대 방안을 발전시킬 필요가 있다. The purpose of this study is to find out the essence of Russia's military strategy in order to accurately read Russia's ideas and logic in the military affairs. In this study the author examined how russian military forces were built and used to respond to such threats in times of emergency. Russia, first of all, considers stronger foreign pressure on Russia since the introduction of Crimea to be a major threat, which is related to maintaining the identity of a superpower. Secondly, Russia regards the United States and NATO as the greatest threats and this will involve maintaining a strategic balance. Third, the U.S. MD, the weaponization of outer space, and the realization of the concept ‘Prompt Global Strike(PGS)’ pose a threat to Russia's future war rediness. To prepare for the threats, Russia has stepped up its military strength by replenishing its forces, modernizing its weapons, preparing for war in key strategic directions, and conducting practical training. In addition, the analysis of actual military operations involving the merger of the Crimean Peninsula and the intervention of the Syrian counterterrorism operation showed that three factos were working such as identity of the superpower, the balance of strategy, and the preparation for a future war. Considering Russia's military strategy, South Korea needs to develop ways to deter war, build military forces centered on threats, and expand military cooperation with Russia to ensure military security.

      • 일본의 군사전략과 우리의 대응

        권태환 ( Kwon Tae Whan ) 한국군사학회 2020 군사논단 Vol.100 No.1

        최근 일본은 인도-태평양 전략을 토대로 미일 동맹을 강화하는 한편, 집단적 자위권 행사 용인과 해병대와 항모 전력 배비 등 새로운 군사전략을 추진하면서 보통국가 행보를 지속하고 있다. 이러한 움직임은 일대일로 구상을 통해 역내 패권을 추구하는 중국의 군사력 증강과 해양진출, 북한의 핵 및 미사일 발사 등 군사적 위협 증대와 맞물리며 역내 군비경쟁을 가속화시키고 있다. 일본은 전후 냉전 해체 등 급변하는 국내외 안보환경 변화 가운데 「적극적 평화주의」를 내세우면서, 미일 동맹을 중심으로 보통국가를 적극 추진하고 있다. 지난 1960년 미일 상호안보조약을 체결하고, 미일 동맹에 의존하는 국가안보를 추진해 왔던 일본은 1976년 방위계획대강과 1978년 미일 가이드라인을 채택한다. 이후 방위계획대강은 2018년 5번째, 미일 가이드라인은 2015년 2번째 개정하고, 2013년 국가안보전략을 발표하며 국가안보체계를 갖춘다. 이러한 관점에서 본다면 일본의 군사전략은 안정된 미일 동맹을 토대로 일관성을 유지하면서도, 정세변화 등 다양한 변화를 반영하여 발전되어 왔다. 일본의 군사전략 분석을 위해 ① 국가안보전략 차원에서 방위계획대강과 미일 가이드라인, 안보법제, 미일 인도-태평양 전략 ② 자위대의 편성과 배치, 방위비 운용, 육해공 전력평가, 방위산업 측면을 대상으로 분석하였다. 도출된 일본의 군사전략은 ① 미일 일체화 전략 ② 미래 선점 군사전략 ③ 독자적 원거리 전력투사가 가능한 자기완결 군사전략 ④ 동맹 네트웍 군사전략 ⑤ 다차원 통합 군사전략이며, 향후 전망과 과제로서 ① 미중 관계의 변화 ② 동북아 군비경쟁의 가속화 ③ 일본 국민들의 안보의식 변화 ④ 한반도 통일 한국의 가능성이다. 결론적으로 우리의 대응을 한일 및 한미일 안보협력 관점에서 제시한다면 ① 한미 동맹 차원에서 한미일 안보협력을 적극 추진 ② 한반도 유사 억제와 대처를 위한 실효적 한일 및 한미일 안보협력 추진 ③ 한일 국방장관 상호방문 등 협력증진 추진 ④ 유엔을 비롯한 우방국과의 연합작전 능력 확대 ⑤ 한일 국민적 공감대 확산이다. 한일 관계는 만들어 지는 것이 아니라 만들어 나가는 것이다. 전쟁은 준비하는 자에게만 승리를 보장한다. 최근 동북아 지역 내 군사적 긴장 고조와 불확실성이 우려되는 상황 가운데 위기를 기회로 만들기 위해 일본 군사전략 분석이 한일은 물론 한미일 안보협력 개선 노력에 도움이 될 수 있기를 기대한다. In recent years, Japan has continued its normal state by strengthening the US-Japan alliance based on the Indo-Pacific strategy, while promoting new military strategies such as concession of collective self-defense rights, and the distribution of marine Corps and aircraft carrier forces. These activities accelerate the arms race in the region, coupled with increased military threats such as China's 「one belt-one road」 for pursuit of regional hegemony and sea-going North Korean nuclear and missile launches. Japan is actively pursuing normal nations based on the USJapan alliance, with [active pacifism] among the rapidly changing domestic and international security environments, such as the dissolution of the Cold War. Japan, which signed the US-Japan Security Treaty in 1960, and has pursued national security that relies on the US-Japan alliance, adopts the 1976 National Defense Prom Guideline, and the 1978 US-Japan guidelines. Afterwards, the defense plan outline was revised five times in 2018, and the USJapan guideline was revised two times in 2015, and 2013 announced a national security strategy and equipped with a national security system. From this point of view, Japan's military strategy has been developed to reflect various changes, including changes in the situation, while maintaining consistency based on a stable USJapan alliance. To analyze Japan's military strategy 1) At the national security strategy level, defense plan outline, US-Japan guideline, security legislation, Japan-India-Pacific strategy. 2) Performance Deployment of Self-Defense Forces Defense Cost Management Analysis of the defense industry by land and air power evaluation. Japan's military strategy was: 1) US-Japan unification strategy; 2) future-first military strategy; 3) self-contained military strategy capable of independent remote power projection; 4) alliance network military strategy; 5) multidimensional integrated military strategy. The future prospects and challenges are: 1) changes in USChina relations, 2) accelerated arms competition in Northeast Asia, 3) changes in security awareness among Japanese people, and 4) the possibility of Korean Peninsula unification. In conclusion, if we present our response from the perspective of Korea-Japan and Korea-US-Japan security cooperation, 1) actively promote Korea-US security cooperation at the ROK-US alliance level. 2) Promote effective Korea-Japan and Korea-USJapan security cooperation in order to suppress and cope with the Korean peninsula. 3) Promote cooperation, including mutual visits by the defense ministers. 4) Expanding capacity for allied operations with the United Nations and other allies. 5) Korea-Japan national consensus spreads Korean-Japanese relations are not just created, but to be created. War guarantees victory only to those who prepare. It is hoped that the analysis of Japan's military strategy will help not only the perspective of Korea and Japan but also Korea-US-Japan security cooperation actually improve their relations in order to turn the crisis into an opportunity amid rising military tensions and uncertainties in Northeast Asia.

        이병길,이재천,Lee, Byoung-Gil,Lee, Jae-Chon 한국군사과학기술학회 2010 한국군사과학기술학회지 Vol.13 No.2

        The necessity of the new system development arises in both defence and commercial systems industry either when a breakthrough in technology needs to be realized in the form of a brand-new system or when the existing product already in operation needs to be upgraded to satisfy the increasing stakeholder's requirements. In the latter case, it is not rare that specific system technical specifications on the existing products are not available. The purpose of this study is to investigate how to handle the difficulty when an upgraded system is required to be developed based on the existing product whose detailed technical specifications cannot be obtained. A step-by-step process is described based on the reverse engineering of the existing product. As a result, a logical system model is obtained for the product. The process developed is further enhanced and evaluated by the computer-aided system engineering tool. The resulting logical system model should be helpful in the next phase of the new product development.

        기존 전술 무전기를 이용한 전술 데이터 통신 성능 실험

        심동섭,강경성,김기형,Sim, Dong-Sub,Kang, Kyeong-Sung,Kim, Ki-Hyung 한국군사과학기술학회 2010 한국군사과학기술학회지 Vol.13 No.2

        The military has been putting great efforts into applying data communication on existing voice communication systems being used in NCW(Network Centric Warfare). Data communication will be an effective choice in one of many effort to yield a minimum kill chain, comparing to legacy voice communications, when tactical units conduct their missions. However, the required budget will be enormous, in case of the replacement of a lot of legacy communication systems with new one. As a cost-effective alternative, the tactical data communication systems using the conventional radio systems instead of the development of new radio systems has been proposed. It is mandatory, though, to ensure QoS while maintaining data communication by making use of legacy radio systems already in use. This paper focuses on the performance issues experimented and analyzed for tactical data communication through the legacy radio systems as the first step towards guaranteed QoS. We have conducted various experiments such as the transmission error rate on certain tactical messages, performance evaluation of redundant transfers, the relationship between the transmission frame size and rate of error, the identification of error points in the transmission frame, and techniques to reduce the errors in both hopping and non-hopping modes. As a result of the performance experiments, The adaptive communication module which decides the redundant transmission or the Forward Error Correction(FEC) technique by analyzing channel status and current transmission status(hopping/non-hopping) of the legacy radio should be designed. the FEC technique in non-hopping, and the redundant transmission technique in hopping mode was recommended from the result of experiment with the frame size is 20bytes in non-hopping and 10Bytes frame size in hopping mode.

        어뢰대항전술 영향을 고려한 수상함의 대잠탐색패턴 연구

        이민규,Lee, Min-Kyu 한국군사과학기술학회 2010 한국군사과학기술학회지 Vol.13 No.2

        The tactical effectiveness, which is the result of applying decision-making algorithms to respond a specific situation with weapons and sensors, is required to analyze according to the integrated combat situation, because each situation, which is intimately involved with each other, influences the surface ship to complete missions successfully. However, the tactical effectiveness have been analyzed in separation of each tactical situation due to the complexity of the integrated tactical situation. This paper is originated from the needs for analyzing the anti-submarine search region of the surface ship after it evades the torpedo by operation of the torpedo countermeasure tactics. It also describes simulation results of effectiveness analysis for the search patterns in the search region.

        임세한,한윤후,장찬주,Lim, Se-Han,Han, Yun-Hoo,Jang, Chan-Joo 한국군사과학기술학회 2010 한국군사과학기술학회지 Vol.13 No.2

        This paper introduces the Hull Mounted Sonar Vertical Scanning(HMS Verscan) technique to overcome the limitation of target detection in short range shadow zone. Numerical experiments were done with the HMS Verscan taking advantage of the vertical beamforming technique for two-dimension hydrospace(range-depth). For numerical experiments, ray model and high-frequency monostatic reverberation model were used. HMS Verscan increased a sound pressure level at the short range shadow zone through reflections at the sea surface and seafloor. Inclusion of the boundary scattering improved target detection due to the sound reflected into the shadow zone.
