Due to recent changes in the maritime traffic environment, naval warship accidents are constantly occurring. Especially in 2017, serious loss of life was caused by a US navy destroyer accident. The purpose of this study is to analyze the characteristics of naval warship accident cases and construct an accident scenario by using naval training materials, adjudication of naval warship accidents and US navy destroyer accident reports. Based on the surveyed data, the status of accidents was identified and cases were analyzed. We reproduced 17 accident cases in accordance with accident reproduction procedure and constructed naval warship accident scenarios. As a result of analyzing the CPA, TCPA and PARK model for risk, reproducing 17 naval ship accident cases, collision risk increased on average 5-6 minutes before an accident. The result of this study represents basic data for naval and simulation education materials, contributing to the prevention of marine accidents.

Since the first Aegis Cruiser USS Ticonderoga was constructed, Arleigh Burke class destroyers are being mass constructed as U.S. Naval capital surface ships and consistently improved the performance. In recent years, the newest aegis combat system, Baseline 9, was deployed. Aegis BMD, aegis ships which have BMD capability, is participated BMDS(Ballistic Missile Defense System) as a sea based BMD. And AN/SPY-1D will be replaced by AMDR(Air & Missile Defense Radar), advanced anti-air radar system to defend effectively against increased ballistic missiles threat from DDG-51 Flight III. In this paper, development status and technical characteristics of each type of aegis ships are researched and characteristics of AMDR are surveyed and described.

To response quickly rapidly changing threats, and to reduce development and operational maintenance budget, U.S. Navy has been significantly applied commercial communication equipments instead of MIL-SPEC equipments. Starting from Aegis Baseline 7 combat system, components of systems were replaced to COTS-based system, and Littoral Combat Ships(LCS) and Zumwalt class destroyers have fully COTS-based combat system. In this paper, it is surveyed and analyzed that cases of COTS-based systems were applied and is compared difference from each type of ships.

Purpose: In order to enhance safety, the Korea Navy is making efforts to introduce a safety and health management system and to develop a risk assessment system, while safety accidents keeps occurring. A development plan was proposed through an inspection of the Safety Management System(SMS). Method: To diagnose the Korea Navy's safety management system, changes in the safety environment, documentation system, and safety and health management system operation were reviewed, points to be improved were found, and improvement directions were derived. Result: There is a need for an SMS standard that can present the Korea Navy's safety policy and safety management direction, and a safety program that provides guidelines for implementing it in a standardized manner. To this end, we were able to confirm the feasibility of linking the requirements of the US Navy's SMS and the international standard ISO 45001 standard together with the Korea Navy's safety management system. Conclusion: The Korea Navy's safety management system needs to clearly present safety policies and standards, and have public confidence and effectiveness in safety work through a standard program that can implement them, and for this, the development of a Navy SMS is necessary.
