The goal of tactical war-gaming is to create an environment for two opposing teams allowing them to make tactical decisions that would correlate with the decision which they would make under the same circumstances while at sea. Therefore the real time war-gaming methodology should be developed to achieve the goal of tactical war-gaming. Surface to surface engagement models for the real time war-gaming such as maneuvering, tracking and damage assessment models were discussed in this paper. Concurrently system flow diagram to aid war-gaming effort was suggested in appendix.

After successful nuclear tests Pakistan launched a more severe surprise attack toward India than before. It is highly possible that North Korea will adopt this Pakistan military strategy if it is armed with nuclear weapons. The North Korean forces armed, with nuclear bombs could make double its war capability through strengthening aggressive force structure and come into effect on blocking reinforcement of the US forces at the initial phase of war time. Therefore we may regard that Pyongyang's nuclear arming is a major one of various factors which increase possibility of waging a conventional warfare or a nuclear war. North Korea's high self-confidence after nuclear arming will heighten tension on the Korean Peninsula via aggressive military threat or terror toward South Korea, and endeavor to accomplish its political purpose via low-intensity conflicts. For instance, nuclear arming of the Pyongyang regime enforces the North Korean forces to invade the Northern Limit Line(NLL), provoke naval battles at the West Sea, and occupy one or two among the Five Islands at the West Sea. In that case, the South Korean forces will be faced with a serious dilemma. In order to recapture the islands, Seoul should be ready for escalating a war. However it is hard to imagine that South Korea fights with North Korea armed with nuclear weapons. This paper concludes that the Pyongyang regime after nuclear arming strongly tends to occupy superiority of military strategy and wage military provocations on the Korean Peninsula.

The Republic of Korean Navy (ROKN) started from scratch. However, ROKN demonstrated its Blue Navy capabilities successfully to the entire world by conducting "Operation Early Dawn" at the Aden Bay, Yemen in Jan 2011. On the event of the 70th anniversary of the ROKN, I would like to retrospect past gleaning from voyages and challenges we had in the past. At the very inception of the ROKN, Korean government as well as senior military leaders recognized that it had no time to spare to clean up military those were insinuated deeply by communist agents. It was the top priority of the government. The Mongumpo Operation which was not well known, conducted by ROKN was one of the clean-up drive. The Korean War sometimes called as "a fire from land put-off at the sea". The world famous "Incheon Landing" which reversed war situation from the Nakdong Perimeter also done by Sea Power. ROKN conducted various maritime operations including not only Incheon Landing, but amphibious operation at Hungnam, mine sweeping, sea convoy, Wonsan Withdrawal. On the same day of the Korean War started, 25th June 1950, unless the victory of the ROKNS Baekdusan (PC 701) at the Korean Strait, the waning lamp light of Korea could not be rekindled by the participation of the U.N. The ROKN rescued the 17th regiment of Korean Army from the isolation at the Ongjin Peninsular and transported gold and silver bars stored at the Bank of Korea to the Navy supply deposit in Jinhae safely. ROKN special intelligence unit conducted critical HUMINT which led Incheon Landing success. One of important mission ROKN conducted successfully was not only transporting war fighting materials but also U.S. provided grains to starving Koreans. ROKN participated Vietnam campaign from 1960s and conducted numerous maritime transportation operations supplying materials to Vietnam military forces along the long coastal lines. Experienced Naval Officers and enlisted men who discharged and acquired as merchant marine certificate supported most of the U.S. sea lift operations throughout the Vietnam campaign. ROK-US Combined Forces which had been honed and improved its war fighting capabilities through the Korean War and out of Vietnam jungle playing key deterrent against threat from north Korea. However, those threat level will be completely different when north Korea finish its nuclear weapon ambition. In order to stand firm against north Korean nuclear threat, I would like to expect strong political leadership supporting nuclear submarine for ROKN.

Purpose of the War history's study is getting instruction by analyzing victory and defeat factor. This study is studied by qualitative form in war study mainly. In case recording literature is full, victory and defeat factor analysis is easy, but occasionally definite analysis that recording literature is feeble is difficult. Also, when it is battle result that escape common sense, about victory and defeat factor, various estimations are brought. As such example, there is Myeong-Ryang sea-battle at Japanese Invasion of Korea in 1592 and Korea(Cho-Sun) naval forces did big victory in 13 vs. 133 numerical inferiorities. This study presented method of study that using agent based simulation model for quantitative analysis of these victory and defeat factor.

The longing for submarine manufacture and the fear of her power had exited for a long time, but submarine that could submerge and attack was built from 20th century by science technology development. The question, 'Submarine can exercise her power in naval warfare?' had exited before World War I, but the effective value of submarine was shown in the procedure of a chain of naval warfare during World War I and World War II. Germany and the United States made the best use of submarines at that time. The submarines of these nations mounted fierce attack on the enemy's battleships and merchant ships and blocked the sea lanes for war material. These fierce attack on ships became impossible After World War II, and the major powers reduced and coordinated the defence budget, so they considered the role of submarine. However, submarine is still powerful weapon system because she can secretly navigate under the water, and one of the most important force in the navy. The aim of this thesis is analyzing submarine roles in each naval warfare and integrating maritime strategy and weapon system technology into her roles. First, the research about represent submarine roles like anti-surfaceship warfare, anti-submarine warfare, intelligence gathering, land attack, supporting special operation and mine landing warfare will be presented, then the major naval warfare where submarine participated(during ex-World War I, World War I, World War II, The Cold War Era and post Cold War) and the analyzing of submarine roles by time will be presented. Submarine was developed for anti-surfaceship warfare during ex-World War I but could not make remarkable military gain in naval warfare because her performance and weapon was inadequate. However, the effective value of submarine in the procedure of a chain of naval warfare was shown during World War I and World War II. The major powers put battleships into naval warfare undiscriminatingly to command the sea power and submarines did massive damage to enemy navy power, so put a restraint the maritime power of enemy, and blocked the sea lanes for war material. After World War II, the battlefield situation changed rapidly and the concept of preemption became difficult to apply in naval warfare. Therefore, the submarine was unable to concentrate on anti-surfaceship mission. Especially during the Cold War era, nuclear submarine came to appear and her weapon system developed rapidly. These development gave submarines special missions: anti-submarine warfare and intelligence gathering. At that time, United States and Soviet submarines tracked other nation's submarines loaded with nuclear weapons and departing from naval their base. The submarines also collected information on the volume of ships and a coastal missile launching site in company with this mission. After Cold War, the major powers despatched forces to major troubled regions to maintain world peace, their submarines approached the shores of these regions and attacked key enemy installations with cruise missiles. At that time, the United States eased the concept of preemption and made the concept of Bush doctrine because of possible 911 terrorism. The missiles fired from submarines and surface battleships accurately attacked key enemy installations. Many nations be strategically successful depending on what kind of mission a submarine is assigned. The patterns of future naval warfare that my country will provide against will be military power projection and coalition/joint operations. These suggest much more about what future missions we should assign to submarines.

1883 년에 진수된 러시아 순양함 드미트리 돈스코이(Dmitri Donskoi ; 6,200톤)호는 러일전쟁에 참전하여 1905년 5 월 29 일 동해 울릉도 근해에서 침몰되었다고 알려져 있다. 이 침몰선을 찾기 위해 1999 년부터 2003 년까지 5 년간 탐사를 수행하였다. 러시아와 일본의 해전사 자료를 토대로 침몰 예상 위치를 파악하여 탐사해역을 설정하였다. 3 차원 해저 지형 조사, 해상 자력 탐사, 천부지층조사, 해저면 영상 조사 등의 기록을 종합 분석하여 침몰선으로 추정되는 이상체를 확인하였다. 지구물리탐사를 통해 확인된 이상체에 대해 심해카메라와 무인잠수정(remotely operated vehicle) 및 유인잠수정 Pathfinder 를 이용한 정밀조사를 수행함으로써 울릉도 저동항에서 약 2 km 떨어진 해역, 수심 400 m 지점의 심해 계곡 중턱에 걸쳐진 돈스코이호를 발견하였다. 침몰선체에는 152 mm 함포 등이 그대로 장착되어 있고 선체 주변에는 전쟁 시 불에 탄 조타기 등의 잔해가 놓여있었다. 조사 지역은 강자성을 띤 대규모 화산암 지대이기 때문에 자력탐사로 침몰선을 식별하기가 어렵다. 천부지층탐사와 해저면 영상조사는 심해 계곡의 심한 지형 변화에 따라 음파의 난반사가 일어났으며 자력탐사 역시 자력이상도의 왜곡으로 인하여 이상체 식별이 곤란하였다. 그러나 중천해용 다중빔 음향 측심기의 경우 탐사선을 최대한 저속으로 운항하고 수심 및 지형에 따라 빔 각도를 조절하여 획득한 해저영상은 침몰선 확인에 매우 유용하였다.

Samuel Eliot Morison (1887-1976) was one of the pre-eminent historians of his generation. He was not only a famous historian at that time, but also was promoted to the rank of Admiral in U.S. Navy Reserve. Fifteen volume History of United States Naval Operations in World War II was published between 1947 and 1962, was not only a comprehensive report on the Navy's projection of power over two oceans, but a classic of historical literature that stands as the definitive treatment of it subject. Although he was fifty-five when war come to America in December 1941. Samuel Eliot Morison was determined to play a role. A professor at Harvard at the time, he joined volunteering for duty in the Navy. An experienced sailor, Professor Morison had earlier sailed that same routes taken by Christopher Columbus while researching his biography, Admiral of the Ocean Sea, which appeared in January 1942 th much acclaim and later got a Pulitzer Prize. Thus Morison plunged into the war, crossing the Atlantic aboard a destroyer. He assumed himself as "Parkman on the sea", tried to follow Parkman's historiographic method, not only participatory history but also literary style. And during writing History of United States Naval Operations in World War II, He emphasized two principles, publicity and objectivity. In terms of publicity, he always worried about who read history and why. In his pamphlet, "History as a Literary Art", he asserted it is useless if readers do not read a history which historians wrote. So he thought historians have forgotten that there is an art of writing of history. Therefore, he built his narratives around brightly rendered visuals and used the present tense to describe actions he witnessed firsthand, he wrote of the U.S. combat in very vividly. But strongly driven by publicity, he sometimes lost his balance in writing the naval history. For instance, the naval history became the focus of criticism for its prejudiced comments about the commanders. Also some reviewers asserted he did not secure the objectivity on writing the naval history. Although he sometimes deliberately torpedoed the objectivity of his work for strengthening publicity, by writing an extensive U.S. naval history, he introduced maritime history and naval history to the public widely. Until in early twentieth century, U.S. historians usually had been focusing their effort to the traditional areas, for example politic, economy, and etc. His intensive effort on the operations of U.S. Navy in World War II aroused a public interest in maritime and naval history. In conclusion, through using literary style and realistic narratives, historian Morison wrote a naval history for all the people which could appealed to the public.

Thanks to the fact that the 1953 Korea Armistice Agreement does not have any clear provisions on the sea demarcation line, the North Korea insists that the sea demarcation line in the Yellow Sea Area should not be the NLL designated by the Commander in Chief. UN Command, unilaterally, but the hypothetical extention of the Latitude Parallel from the end of the provincial boundary line between Whanghae-do and Kyongki-do In those unique situations at the end of the Korean War, the cease-fire line on the part of the western sea area, a logically indispensable element of the contents of an armistice agreement, however has formed and crystallized by the act of the UN Command designating the NLL. In implementing the South-North Korean Basic Relations Agreement, a fair and clear common consent on the sea demarcation line in the western sea area should be deliberated.

임진왜란 해상전투에 사용된 이순신의 거북선 복원에 대한 논쟁은 계속되고 있다. 그 이유는 임진왜란에 사용된 거북선의 외부, 내부구조와 형태를 구체적으로 파악할 수 있는 사료(史料)가 현재까지 남아있지 않기 때문이다. 현재 복원된 거북선은 정조 19년(1795)에 왕명으로 편찬된 이충무공전서의 전라좌수영, 통제영 거북선의 목판화 그림과 설명문, 사료의 내용을 토대로 복원되었으나 두 거북선은 임진왜란 후 203년 뒤인 정조대의 거북선으로 임진왜란 당시의 거북선과는 같지 않고, 현재 복원된 임진왜란 이순신의 거북선은 임진왜란 당시의 문헌의 기록과 일치하지 않는 구조적, 형태적인 많은 문제점을 가지고 있다. 문헌에 나타난 최초의 거북선 그림인 1593년 이덕홍 귀갑선도는 그동안 거북선의 연구에서 중요시 되지 않았으나 임진왜란과 시기적으로 일치하고 그림 해석을 통한 구조분석과 판옥선, 전라좌수영, 통제영 거북선과의 관계를 분석하면 개판 윗면의 중앙부분은 평면구조이고, 전후좌우로 창검이 꽂혀있는 구조로 임진왜란 당시 기록의 내용에 접근된 거북선의 구조와 형태를 도출할 수 있다.
