Naval CMS(Combat Management System) is linked to various sensors and weapon equipment and use DDS(Data Distribution Service) for efficient data communication between ICU(Interface Control Unit) Node and IPN(Information Processing Node). In order to use DDS, software in the system communicates in an PUB/SUB(Publication/Subscribe) based on DDS topic. If the DDS messages structure in this PUB/SUB method does not match, problems such as incorrect command processing and wrong information delivery occur in sending and receiving application software. To improve this, this paper proposes a DDS message structure integrity verification method. To improve this, this paper proposes a DDS message structure integrity verification method using a hash tree. To verify the applicability of the proposed method to Naval CMS, the message integrity verification rate of the proposed method was measured, and the integrity verification method was applied to CMS and the initialization time of the existing combat management system was compared and the hash tree generation time of the message structures was measured to understand the effect on the operation and development process of CMS. Through this test, It was confirmed that the message structure verification method for system stability proposed in this paper can be applied to the Naval CMS.

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.

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.

In this paper, the virtual environment using rack server type HPC and 3U VPX server type HPC was applied and tested to the basic functions of the Jangbogo-III class submarine combat system developed for the first time in Korea. Based on this test results, the possibility of applying virtualization to the domestic submarine combat system to be developed in the future is confirmed. Existing studies have been limited to deriving applicable virtualization solutions through simple performance analysis of virtualization solutions or applying virtualization to some functions of the surface ship combat system, but in this paper, the application of virtualization is expanded to the submarine combat system through testing.

미래의 해전은, 현재와 같은 추세로 살펴본다면 무기 체계의 첨단 기술이 개발이 되었을 경우, 미사일 전쟁화가 될 것으로 추정이 된다. 본 연구에서는 현재 미 해군이 차세대 구축함으로 개발하고 있는 DD2l함을 근거로 해서 전투효율과 경제성에 기초를 둔, 차세대 함정이 갖추어야 할 필요 충분 조건이 무엇인가를 고찰하기로 하였다. 하나의 임무를 갖춘 함정의 여러 척수와 다종 임무를 갖춘 한 척의 함정간의 전투 효율과 경제성에 대한 비교로 부터, 다종 임무를 갖춘 한 척이 양측면에서 우수하다는 사실이 전술과 전략 측면에 관한 각종 연구를 통해 평가되고 있다.

The IISS(Integrated Interface Storage System) software performs the function of transmitting tactical domain messages of Combat Management System for interface analysis of Naval Combat System. The source code is relatively large because the IISS software handles most messages. The modifications of source code of the IISS software occur frequently due to changes in interconnected equipment and messages. Therefore, additional effort and cost are required during the development process. In this paper, we studied standardization of the IISS software to improve reusability. Through the feature model, the components of the IISS software were divided by function and modification elements were separated. And the structure of the IISS software was improved by applying design patterns. As a result, it was possible to minimize modifications of the IISS software by changes in interconnected equipment and messages and a reduction in development costs could be expected.

Most battleship warfare M&S systems run relatively slow and the simulation results are often unfair since the system should interact with human operators(controller and/or gamer). To deal with these problems, we have proposed the agent-based battleship warfare M&S system which interact with multiple agent systems instead of human operators. Agent-based M&S system may be able to efficiently support the analysis of effectiveness and/or the operational tactics development of given warfare by providing autonomous reasoning capabilities without the intervention of human controller. To do this, the paper propose the design concept and methodology using the advanced modeling and simulation framework as well as autonomous agent design principle. Several simulation tests performed on the battleship warfare case study on Korea Yellow sea will illustrate our techniques.

Since 1993, Successfully localized naval combat System has made steady development on various domestic and foreign ships. On the other hand, Engineering Control System(ECS) is dependent on foreign companies. Therefore, there is a lot of interest and research in the localization of ECS in the navy defense industry. As one of various studies, a preliminary study of domestic ECS software that can be commonly applied to naval ships is in progress. This paper propose Ecs Obts Scalable Platform(EOSPA) as the standard architecture of ECS On-Board Training System(OBTS) software by applying object-oriented programming and standardization. And this introduces EOSPA's structure, function, and features of each component. Furthermore, high reusability and maintainability are expected in the development of ECS OBTS software applying EOSPA in various naval ships.

In this paper, the combat effectiveness of ship guidance rockets to counter the threat of multiple USV(Unmanned Surface Vehicle) was analyzed in three cases. The probability of sinking a number of USVs approaching by distance was compared using various weapon systems and guided rocket systems installed on the naval vessels. As a result of the analysis, it was found that the combat effectiveness of the guided rocket was improved compared to the close defense system of the anti-ship missile installed on the naval vessels.

It is very important for the combat system to process extensive data exactly at short time for the better situation awareness compared with the threats in these days. This paper suggests to add radial velocity on the decision factor of sensor data fusion in the existing algorithm for the accuracy enhancement of the sensor data fusion in the combat system.
