Recently, as weapon systems have been more diverse and complicated, the factors of risk increase in development. Consequently, demanding reduction of acquired costs and period increase. Under the acquisition environment, more efficiently to develop weapon system, the necessity of application of defense M&S from requirement phase is on the rise. As the importance of M&S is stressed under distributed environment, so the standard of M&S(HLA, SEDRIS, etc.) and the system engineering process, namely FEDEP(Federation Development & Execution Process) have been developed. In this paper using the 5 phase expression, we constructed underwater engagement simulation(UNES) that prototype to develop naval weapon system test bed which take up integrated architecture in HLA. we developed simulators according to FEDEP for expandability and described process applying FEDEP fur UNES development.

As a concept that commercial parts are applied to weapon systems, Commercial Off-The-Shelf(COTS) was not well-received at a time when defense technology led commercial technology. However, the exponential growth of IT and the rapid expansion of commercial industry have made possible to make the cost low through mass production system within a short period, and the benefit of cost and schedule has been highlighted, triggering commercial parts to be applied to weapon systems. In order for commercial technology to be used in defense weapon systems, its performance in an extremely restricted condition of combat environment should be guaranteed. Generally, commercial parts have fundamental limitation in that the design and production requirements for commercial parts are different from those for the military. Therefore, it is required to confirm that commercial parts can be used for weapon systems through the approach of system engineering. This study presents the process tailored to characteristics of marine defense system and the method of analyzing its restricted condition in order to apply COTS to marine defense system. The study classifies the restricted conditions into general and special environments, suggests detailed process, and suggests useful tools to select appropriate items adapted to these restricted conditions in the commercial market. Lastly, as a case study for COTS applied to marine defense system, the study finds out the analysis results of application of COTS and restricted conditions of the warship electric system.

From ancient times to the present day, naval warfare in history is deeply connected with the rise and fall of countries. This study examines which countries won wars by tracing naval warfare that they had carried out. Seven Cases are traced for the analysis including the battle of Salamis and the Poeni War in the ancient period, the battle of Calais in the medieval and modern periods, the Russo-Japanese War in the modern period, and the Falklands War in the present age. The results show three fundamental characteristics. First, countries that won naval warfare were armed with the state-of-the-art weapon systems and conducted joint operations effectively. Second, countries that fought in the usual ways were defeated by challengers. Third, countries such as Athens, Rome, Britain and the United States ascended to the hegemony by winning major naval warfare and then commanding or controlling the sea at their own free will. Countries defeated in these naval warfare, however, descended to the weak powers. In general, countries that won warfare have a tendency to make light of defeated countries, not to introduce new weapon systems from abroad, and to stick to their traditional ways of fighting. These lessons indicate that the ROK military needs to continue the development of new weapon systems at peacetime. In addition, they show that it needs to focus more on the articulation of military doctrines and training systems so that warriors on the battlefield can fight better.

The fourth industrial revolution based on the intelligent revolution has revolutionized the society as a whole, and it has also affected the defense sector. Various aspects of the war have been changing with the development of technology. In particular, various strategies such as research and development of core technology related to defense unmanned system field and infrastructure are being established based on the fourth industrial revolution technology. In this paper, we have conducted a study to select the technology required for maritime unmanned systems, which can be considered as a priority consideration for the future development of the core technology to be secured prior to the development of the weapon system. First, the core technology prioritization model for the marine unmanned system was established, and the technology fields of the unmanned robot were reclassified and integrated in the related literature such as the classification of the defense technology standard. For the empirical analysis, a questionnaire survey was conducted for 12 specialists who are engaged in the planning of weapons systems, and the importance of technical fields that require development in the development of marine unmanned systems was analyzed. As a result, it was possible to identify the key technology areas that should be considered in selecting the key technologies proposed by the military groups, research institutes, and companies. This could contribute to the establishment of the technology roadmap to develop the marine unmanned system from the future point of view.

This study proposes a new convergence weapon system that combines the covert placement and detection abilities of a self-propelled mobile mine with the rapid tracking and attack abilities of supercavitating rocket torpedoes. This innovative system has been designed to counter North Korea's new underwater weapon, 'Haeil'. The concept behind this convergence weapon system is to maximize the strengths and minimize the weaknesses of each weapon type. Self-propelled mobile mines, typically placed discreetly on the seabed or in the water, are designed to explode when a vessel or submarine passes near them. They are generally used to defend or control specific areas, like traditional sea mines, and can effectively limit enemy movement and guide them in a desired direction. The advantage that self-propelled mines have over traditional sea mines is their ability to move independently, ensuring the survivability of the platform responsible for placing the sea mines. This allows the mines to be discreetly placed even deeper into enemy lines, significantly reducing the time and cost of mine placement while ensuring the safety of the deployed platforms. However, to cause substantial damage to a target, the mine needs to detonate when the target is very close - typically within a few yards. This makes the timing of the explosion crucial. On the other hand, supercavitating rocket torpedoes are capable of traveling at groundbreaking speeds, many times faster than conventional torpedoes. This rapid movement leaves little room for the target to evade, a significant advantage. However, this comes with notable drawbacks - short range, high noise levels, and guidance issues. The high noise levels and short range is a serious disadvantage that can expose the platform that launched the torpedo. This research proposes the use of a convergence weapon system that leverages the strengths of both weapons while compensating for their weaknesses. This strategy can overcome the limitations of traditional underwater kill-chains, offering swift and precise responses. By adapting the weapon acquisition criteria from the Defense force development Service Order, the effectiveness of the proposed system was independently analyzed and proven in terms of underwater defense sustainability, survivability, and cost-efficiency. Furthermore, the utility of this system was demonstrated through simulated scenarios, revealing its potential to play a critical role in future underwater kill-chain scenarios. However, realizing this system presents significant technical challenges and requires further research.
