This paper provides an empirical assessment of the development of North Korea's Anti-Ship Ballistic Missile (ASBM), and its influence on South Korea's maritime strategy. While research studies on North Korea's ballistic-missile capabilities and South Korea's ballistic-missile defense systems are proliferating, less analytical attention has been given to the way that the strengthening of North Korea's ballistic-missile capacities presents a critical threat to the ROK's navy and lines of communication. The authors of this paper identify the continuing development of unique ASBM capabilities by China and Iran, and determine that such processes are mutually interactive and in accordance with threat perceptions; furthermore, North Korea can enact the same process by learning lessons from these nations. The findings of this paper provide an implication for the formulation of South Korea's maritime strategy and the related assets in consideration of the ASBM as a future threat.

Today, Kim Jong-un, the third-hereditary regime in North Korea, is committing Nuclear Provocation more aggressively than the past when Kim Il-sung and Kim Jong-il dominated. Past South Korea government had suggested plans to restrain the provocation from North Korea and bring stabilization in the Korean Peninsula. However, consequentially it was limited to the primary role of the President. When President Trump takes over the government in February 2017, it has attracted the expectation about the issues occurred on the Korean Peninsula due to the pledge that he promised during the presidential election and his govern style. However, various speeches about the Korean Peninsula that he spoke recently made situations depressed about what South Korean currently encounters. Furthermore, previous regime in North Korea has laid the foundation for Kim Jong-un to be obsessed more on the nuclear and missile which has led him to provoke more imprudently by highlighting the light weight, advanced, and various kinds of nuclear and missiles. Thus, we would like to propose counter measures in order for South Korean government to handle and solve the issues that they encounters by themselves based on North Korea's Nuclear Provocation instead of relying on other countries to get involved and help.

The purpose of this article is to analyze the progress of North Korea's SLBM threat, and to assess the technological capacity and threat level of its SLBMs. Currently, North Korea has approximately 1000 ballistic missiles, such as the SCUD, Musudan, and Nodong, in stock. This article pays close attention to the background and strategical implication behind North Korea's obsession with developing SLBMs despite possessing sufficient means to launch provocations with its current arsenal of ground based ballistic missiles and conventional weapons. Based on the abovementioned analysis, this article will recommend possible response directions for the ROK Armed Forces to North Korea's SLBM threat. It is highly difficult to detect SLBMs due to its stealthy nature, as it is launched underwater after covert infiltration. North Korea's SLBM is considered a game changer in that even one SLBM can significantly change the strategic balance of North East Asia. North Korea's SLBM test launch in August has made a 500km flight, landing 80km inside the JADIZ (Japan Air Defense Identification Zone), and as such, it is assessed that North Korea already possesses underwater ejection and cold launch capabilities. The most realistic response to North Korea's imminent SLBM threat is bolstering anti-submarine capabilities. ROK Armed Forces need to upgrade its underwater kill-chain by modernizing and introducing new airborne anti-submarine assets and nuclear-powered submarines, among many options. Moreover, we should integrate SM-3 missiles with the Aegis Combat system that possess strong detection capabilities and flexibility, thereby establishing a sea-based Ballistic Missle Defense (BMD) system centered around the Aegis Combat System, as sea-based ballistic missile threats are best countered out in the seas. Finally, the capabilities gap that could arise as a result of budgetary concerns and timing of fielding new assets should be filled by establishing firm ROK-US-Japan combined defense posture.

The North Korean regime, Kim Jungun's foreign policy is changed frequently. And their military policy has no gravity. North Korea has developed nuclear weapons and long range missile. Now they have Inter-Continental Ballistic Missile. These activities redound a great threat in Korean peninsula. There are a no possibilities to give up its nuclear weapons and missile development. For the peace in Korean peninsula, we should make North Korea to abandon its nuclear himself through effective sanctions. Now China should effort to control North Korea. To reduce the threat we should coordinate the strategic interests of China and US. This study is to predict the North Korea military activities to analyze "military policies."

The balance of power in conventional forces between the two Koreas works in favor of the South Korea in the Korea peninsula. But, the balancing mechanism between the two Koreas in asymmetric forces like nuclear and missile forces works absolutely in favor of the North Korea. That's why it should be timely for the ROK military to review existing strategy and revise a new counter strategy against the threat posed by the North Korea's nuclear and missile forces. The ROK military is now developing 4D, KAMD, KILL Chain strategies as means to cope with the North Korea's nuclear and missile threats. Considering efforts and resources invested now, the strategies are expected to be in place in next five or more years. However, approaches to those strategies seem to be rather fragmentary and conceptual than comprehensive and pragmatic. The types of strategies against the North Korea's military threats need to be a deterrence in peace time and a fighting and winning in war time in the Korean theater. But, the most important element in the deterrence strategy is the credibility. This study concludes with an new strategic concept titled "ADAD(Assured Defense, Assured Destruction)" as an alternative to existing strategies to deal with the North Korea's nuclear and missile threats.

This paper presents research on predicting the possible intercept time for a Nodong missile based on its flight trajectory. North Korea possesses ballistic missiles of various ranges, and nuclear warhead miniaturization tests and ballistic missile launch tests conducted last year and in previous years have made these missiles into a serious security threat for the international community. With North Korea's current miniaturization skills, the range of the nuclear capable Nodong missiles can be adjusted according to their use goals and operating environment by using a variety of adjustment methods such as payload, fuel mass, Isp, loft angle, cut-off, etc., and therefore precise flight trajectory prediction is difficult. In this regards, this research performs model simulations of the flight trajectory of North Korea's domestically developed Nodong missiles and uses these as a basis for predicting the possible intercept times for major ballistic missile defense systems such as PAC-3, THAAD, and SM-3.

After the yield of North Korea conducted underground the first nuclear test in 2006, which was less than a kiloton, it launched a vehicle on this April 9 again, which is believed to be a Taepo-dong 2 missile, defying international warnings that the move would violate U.N. resolutions, from Musudan-ni, North Korea. Its development and proliferation of ballistic missile and nuclear bomb technology pose a threat to the northeast Asian region and to international peace and security. In the other launching the missile, a newspaper reported that "While the launch was dubbed a failure by the U.S., it was an improvement over the North Koreans' July 2006 test of the Taepodong-2, said Green of the Center for Strategic and International Studies. "It was definitely better than last time, but it's still not an operational system," Green said.

The ballistic missile is very threatening weapon system because it is difficult to detect and intercept due to fast speed. Recently, many countries worry about North Korea's ballistic missile launching tests especially the success of launching Kwangmyongsong-3 satellite by Eunha-3 long range rocket at 2012. This event means announcement of North Korea have capability to develop ICBM(Intercontinental Ballistic Missile) to all over the world. In this paper, it is surveyed and described that history, types and threat of ballistic missiles.

North Korea has continued developing ballistic missiles with various ranges. Even through the recent launch long-range missiles, it can be inferred that North Korea's Missile technology has reached a level where it can even threaten the US. moreover, through the three times nuclear tests, North Korea is known to have succeeded at gaining 10~20KT of explosive power as well as the minimization and lightening of nuclear warhead. Considering the short length of war zone in Korean peninsula and the possibility of nuclear equipment, if be the most severe threat across the whole peninsula. Since the midcourse phase flight takes the longest time, ROK should establish the ability to intercept at this middle phase. From this perspective, this paper describes mission effect of a sea-based BMD system through empirical threat and flight characteristic analysis using MIT model that was not suggested in original research.

South Korea should correspond to the primary threat to North Korea's nuclear weapons. It is necessary to have countermeasures to solve the realistic problems of North Korea's nuclear weapons. We can intensify military pact between the United States and Korea and at the same time strengthening the current military power. Currently, we take note the threat North Korea's missile. We can not control the development of a nuclear weapon and there are possibilities that North Korea have successfully miniaturized nuclear enough to carry by the missile. We should overview and check the Korea's missile defenses system. While the direction of the overall missile defense system deployment with a focus on lower and upper air defense network. And discuss defense research should be to build a system that can be protected with a key strategic facilities and cities. While North Korea have nuclear weapon, the main issues related to North Korea's nuclear threat. The six party talks countries try to solve the problem by the international and diplomatic approach. At the same time we should make somewhat to defend measures such as military defenses of Kill chain system to protect our country. Kill Chain is on of the effective defense system. We know that North Korea do not abandon to develop nuclear weapons by diplomatic efforts. We should performed in fact by a variety of military suppression method.
