This technical paper presents future missile trends and propulsion technologies necessary for the missiles. The views are based on open literature briefings of the United States and internet informations. These informations let domestic incorporations prepare technologies for the future. Political and economical environment has been changing worldwidely. More extensive role is required for the incorporations to increase the economic growth of our country. The incorporations should establish the long term product development strategy of their own to compete with foreign countries.

In order to use missiles more effectively, assessing methodologies was advanced about weapon effects for various target types. We tried to find out the most effective analysis methodologies for missiles to attack 3 dimensional building target's and analyzed adaptedness as an assessing methodology. There are EFD (Expected Fractional Damage) and SSPD (Single Sortie Probability of Damage) methodologies to assess building target damage. In order to calculate effectiveness we used input parameter such as size of the target and CEP (Circular Error Probable), MAE_bldg (Mean Area of Effects for Building) of weapons and impact angle as encountering condition between the target and the missile. We compared EFD and SSPD, in order to analyze adaptedness as a effective methodology by CEP and MAE. The result was that EFD methodology was more adaptive to assess 3 dimensional building targets by missile systems than SSPD.

In the performance analysis of a weapon system, the combat effectiveness is difficult to go beyond the conceptual level in the early stages of development. This is especially true in the case of new concept of weapon system that has never existed before. In this study, with the aim of analyzing the effectiveness of small personal guided weapons, the design of the warhead and the detonation test were carried out and the results were analyzed. Afterwards, trajectory of fragments were calculated from the results, and it is applied to the anti-personnel effectiveness logic which is a part of combat simulation tool. At the same time, delivery accuracy logic was constructed from Monte-Carlo simulation with 6-DOF trajectory model. Subsequent simulated experiments were conducted with test scenarios to confirm the simulation logic reflecting the results of the warhead detonation tests for verifying the simulation approach of weapon systems, and it was confirmed that the simulation logic incorporating the results of the warhead detonation tests functioned properly.

In the defense field, weapon systems are increasing in importance, as well as the weight of the weapon system embedded software development as an advanced technology. As the development of a network-centric warfare has become important to secure the reliability and quality of embedded software in modern weapons systems in battlefield situations. Also, embedded software problems are transferred to the production stage in the development phase and the problem gives rise to an enormous loss at the national level. Furthermore, development companies have not systematically constructed a software reliability test. This study suggests that approaches about a qualityverification- system establishment of embedded software, based on a variety of source code reliability test verification case analysis.

In this study, we presented the periodic inspection method of the Certified Missile Round Concepts usuing M&S(Modeling and Simulation) techniques. Firstly, We drew up the scenario from the application concepts and the predicted dormant reliability Secondly, we performed the modeling for a simulation program based on the scenario. Lastly we embodied the simulation program. After comparing and examining the difference between the simulation results and the theoretical estimates, we present the best periodic inspection plan for achieving the probability of success.

This paper presents the study result on a realization of wireless umbilical device for missile systems. In general, a missile system is connected to a fire control equipment via an umbilical connector to get the electrical power for its internal equipment and communicate with each other. And these connectors inherently have many problems of mis-contact between pin and socket, and mis-separation during missile firing, etc. A wireless umbilical device using LC resonance is devised to solve these problems of the current technology. For hundreds of watts power transmission under the missile system environment of restricted space, we designed and made a prototype of wireless umbilical device. And we tested this wireless umbilical device with an aluminum cylinder having cutout windows which simulate missiles. We realized that the wireless technology can be used as a substitute for the conventional umbilical connectors, and EMI and environment tests should be followed further.

Verification, Validation & Accreditation (VV&A) process is widely applied in various disciplines as a method of acquiring the credibility for M&S tools. The guideline of VV&A states that the detailed process can be established flexibly according to the needs and the availability of resources. For example, DAPA (Defense Acquisition Program Administration) guideline suggests that the accreditation process in the VV&A can be omitted if necessary. On this study, we first introduce and describe V&V process. Accreditation process is omitted due to limited time and resources. However, the proposed V&V is sufficient for our needs. Finally, we apply the proposed process of V&V to the System-Integrated Simulator of "Raybolt", Medium-Range Infantry Missile System, for the acquisition of the M&S credibility.

Airfield pavements, such as runways and taxiways, are essential for smooth take-off and landing of fixed-wing aircraft and are the most important installation for the military to carry out air operations during wartime. Therefore, in wartime, it is necessary to reduce the damage to these installations and repair them in the shortest possible time. Recently, the pattern of attack is changing from the use of conventional high explosive which is to create large craters to the use of multiple warheads weapon system which is to effectively attack enemy's airfields but unrelated to accuracy. Hence in this study, through identifying the specification and composition of multiple warheads weapon system, we checked the protection performance and damage patterns of the pavement when explosion occurred on the installed military runway and taxiway by the multiple warheads weapon system. And The multiple warheads weapon systems is able to cause extensive damage but the destructive power of each warhead is not as great, so I would like to propose an airfield pavement design plan for minimal protection against such attacks.
