Naval command and control system are very important for operation and their failures can be fatal for warfare. To prepare for these failures, we use feature selection method which is one of the data mining techniques. First, we analyzes failure data set of Navy from 2016 to 2018. And then We derive attributes that are associated with failure and to predict failure using feature selection method. We propose a method for prioritizing maintenance using the degree of association of attributes. This improves the efficiency and economics of command and control system maintenance.

The future warfare is changing to the NCW(Network Centric Warfare) from the platform-based warfare. Korea navy has been developing the KNCCS (Korea Naval Command and Control System) and the KNTDS (Korea Naval Tactical Data System) to prepare the NCW. Also, Korea navy has been using the ICS (Integraed Communication System) to transfer the command, control and tactical information on the naval ship. There is a lack of a systematic research and a reference material, although the ICS is a very important network on the naval ship. This paper is described the naval ICS. Also, a direction of the next Korea naval ICS is proposed.

한국의 해군력 건설 방향은 미래 해양 안보환경과 국가경제력에 상응함은 물론 주변국 해군에 대해 균형자적 역할을 담당할 수 있는 정예 해군력으로 건설해야 할 것이다. 이런 의미에서 수상 전투함은 높은 안정성, 고감도 탐지 장비와 함정 전투체계에 의한 성분작전 수행 능력 및 전역 탄도미사일 방어를 위한 탐지, 추적, 요격 및 실시간 지휘통제를 위한 함정 전투체계의 능력완비 등을 목표로 개발해 나가야 할 것이다.

The representative concept of the future war is NCW. The main point of NCW is that it is connected by networ ks and gathers the battlefield status in real time, managing and controlling it. This is most needed in the navy. Operations of the navy are carried out in wide areas, individually or together. During this process, sharing information between each warship should be essential. Furthermore in the case of the American navy, they see the entire world as the operation area so it is a representative example of NCW. The C4I system of the Korean army is separated a ccording to the difference of each army's tactics and weapon system, being developed and managed differently. The refore there is a problem of interoperability lacking in each system. This paper analyzes the developed C4I system of the American navy to analyze the problems of C4I system of the Korean army, and propose the future direction of its development.

Aegis Combat System(ACS) is a shipboard combat system developed by U.S. Navy. Its name, Aegis, came from a shield 'Aegis' in greek mythology, which Zeus gave to his daughter Athena. U.S. Navy uses Aegis ships(ships which mount ACS) as their main surface forces. It is known as one of the greatest anti-air warfare ship in the world by its ability to detect air threats with AN/SPY-1, phased array radar, superior Target management and command and control capabilities of the combat system, and SM series interceptors. After first Aegis cruiser USS Ticonderoga was deployed at 1983, U.S. Navy continuously put effort in developing Aegis Combat Systems and Aegis ships. They also improve old fashion existing ships by modernize them. In this Paper, to deduct a lesson which Korea Navy should benchmark, it is went through that a history of Aegis ships and development of ACS, and also its feature.

The Korean navy has been using the ICS(Integrated Communication System) to transfer a command, control and information on the naval ship. The major equipment for the ICS has been imported from abroad, so that there were some problems such as lack of logistics support, leaking military secrets. This paper describes considerations for the development and the key technology of the domestic ICS which is developed to solve the problems mentioned above and to integrate various future communication elements on the naval ship.

Naval battleships have systems to perform special purposes, such as the Command and Fire Control System (CFCS). Some of the this equipment should be equipped with an Uninterruptible Power System (UPS ) to ensure operational continuity and the backup of important data, even during unexpected power outages caused by problems with the ship's power generator. Heavy combat losses can occur if the equipment cannot satisfy the function. Therefore, it is important to design a stable UPS. The battery and Battery Management System (BMS) are two of the most important factors for designing a stable UPS. A power outage will be encountered if the battery and BMS are not stable. The customer will be exposed to abnormal situations, loss of important tactical data, and inability to operate some of the CFCS. As a result, an enhanced safety system should be designed. Thus, this study implemented and verified the improved system in terms of three methods, such as comparative analysis of the batteries, improvement about leakage current of the circuit, and tests of the aggressive environmental resistance to improve the UPS for CFCS.

In 2017, the U.S. DARPA coined 'mosaic warfare' as a new way of warfighting. According to the Timothy Grayson, director of DARPA's Strategic Technologies Office, mosaic warfare is a "system of system" approach to warfghting designed around compatible "tiles" of capabilities, rather than uniquely shaped "puzzle pieces" that must be fitted into a specific slot in a battle plan in order for it to work. Prior to cover mosaic warfare theory and recent development, it deals analyze its background and several premises for better understanding. The U.S. DoD officials might acknowledge the current its forces vulnerability to the China's A2/AD assets. Furthermore, the U.S. seeks to complete military superiority even in other nation's territorial domains including sea and air. Given its rapid combat restoration capability and less manpower casualty, the U.S. would be able to ready to endure war of attrition that requires massive resources. The core concept of mosaic warfare is a "decision centric warfare". To embody this idea, it create adaptability for U.S. forces and complexity or uncertainty for the enemy through the rapid composition and recomposition of a more disag g reg ated U.S. military force using human command and machine control. This allows providing more options to friendly forces and collapse adversary's OODA loop eventually. Adaptable kill web, composable force packages, A.I., and context-centric C3 architecture are crucial elements to implement and carry out mosaic warfare. Recently, CSBA showed an compelling assessment of mosaic warfare simulation. In this wargame, there was a significant differences between traditional and mosaic teams. Mosaic team was able to mount more simultaneous actions, creating additional complexity to adversaries and overwhelming their decision-making with less friendly force's human casualty. It increase the speed of the U.S. force's decision-making, enabling commanders to better employ tempo. Consequently, this article finds out and suggests implications for Korea armed forces. First of all, it needs to examine and develop 'mosaic warfare' in terms of our security circumstance. In response to future warfare, reviewing overall force structure and architecture is required which is able to compose force element regardless domain. In regards to insufficient defense resources and budget, "choice" and "concentration" are also essential. It needs to have eyes on the neighboring countries' development of future war concept carefully.
