Advanced military nations have developed anti-tank smart munitions to maximize the effectiveness of the tank combat. In this paper we introduced new munition models (KSTAM) for arrack on the top of the tank and analyzed those operation research. To understand the adaptation to the future tank munition we have performed a trade-off study using the proposed models for smart tank munitions which have been developed or are being developed in advanced nations.

In this study, insensitive munitions(IM) policies and technologies of advanced countries for solid rocket motor were investigated. Development trends and caseworks of each part such as propellant and motor case of rocket motor for IM were also studied. Based on these investigation and analysis for IM rocket motor, directions of the development for IM rocket motor in our country were suggested.

A roll rate estimation method is proposed using the GPS measurement for spinning vehicles such as guided munitions and smart bombs. Before designing the roll rate estimator, the carrier phase and the carrier frequency deviation caused by spinning have been observed. Based on the observation, the spinning frequency is estimated using I and Q value from the correlator. The proposed method is evaluated through computer simulations using a software defined receiver and a GPS IF signal generator.

예기치 않은 외부의 자극으로 인한 유도무기의 사고에 의해 인명 및 무기체계의 피해를 최소화하기 위하여 유도무기 둔감화 연구가 미국과 NATO를 중심으로 80년대 초반부터 활발히 수행되어 오고 있다. IM(insensitive munitions)은 예기치 않은 외부 자극에 노출되었을 때 성능과 작동요구조건을 충분히 만족시키면서 격렬한 반응을 최소화하는 무기로 정의된다. 1995년도까지 미 해군에서 사용하는 모든 전술 유도무기를 MIL-STD-2105B의 요구 조건에 부합하도록 둔감화 하기 위하여 1984년 미 해군에서 IM 프로그램이 만들어졌고, 1991년에 NATO의 NIMIC(NATO Insensitive Munitions Information Center)이 만들어져서 현재까지 둔감화약, 둔감 추진제, 복합재연소관 및 완화장치 등에 연구가 활발히 이루어지고 있다.

This paper proposes a new guidance law for increasing the lethality of munitions. The well known PNG (Proportional Navigation Guidance) is inadequate for the munitions because of some weaknesses. Even if the munition does not have the impact point error, the acceleration command is non zero because the line-of-sight changes at all times in flight. Therefore, we use a difference between a target and an impact point. This proposed guidance law is similar to PNG in the form, but this guidance law concentrates a correction rate of flight path angle instead of the LOS (Line of Sight) rate. The correction of flight path angle is defined as the amount of impact point error. This impact point error can be calculated by neural networks rapidly. Finally, we show that the simulation results prove the suitability of this law.

Until now it has had the limitation of the target in the US JMEM to calculate the Pk with the existing method by our study. In this study, we focused on deriving a method to calculate the Pk of the actual targets except JMEM targets using ANN. We study the initial predictive model of ANN(Artificial Neural Network) from the targets data of the specification and the vulnerable area in the US JMEM(Joint Munitions Effectiveness Manuals), and calculate the actual targets vulnerable area by using this method. Finally, we propose a method to calculate the Pk by applying those data to the existing method of us.

Currently, the Defense Agency for Technology and Quality (DTaQ), which is responsible for the quality assurance of military supplies, divides munitions into four categories, in order to conduct its governmental quality assurance activities, including product examination, process review and system audit. However, these 4 categories may differ depending on the related organizations' (e.g. Defense Acquisition Program Administration, munitions manufacturing) military requirements. Therefore, in this study, appropriate classification criteria for munitions are suggested for the sake of the efficient procurement, production and quality assurance of military supplies. We investigated the item classification system of the Public Procurement Service, which is a similar organization to the DTaQ. We also compared the appropriate classification criteria with those of related organizations and identified the current status of munitions classification data according to the current standard. In addition, application samples are presented using the proposed quality assurance classification criteria. Finally, the classification criteria of military supplies proposed in this paper will contribute to improving the efficiency of government quality assurance activities.

Insensitive Munitions(IM) of solid propulsion system are defined as munitions that fulfil the performance and operational requirements, but will minimize the violence of a reaction when subjected to inadvertant stimuli. It should be clear that the reaction violence of rocket motor subjected to thermal stimuli can be mitigated by reducing confinement prior to propellant reaction. Devices designed to do this by venting the rocket motor case are commonly referred to as mitigation devices. The objective of this paper is to introduce the technical information related to the pyrotechnic mitigation devices for insensitive munition of solid rocket motor.

Insensitive Munitions(IM) test methods and passing criteria of MIL-STS-2105D revised in April 2011 were studied since MIL-STD-2105(NAVY) had been created in 1982. Passing criteria of each IM tests has not been established because domestic database of IM tests for rocket motors was not enough, even though IM test and evaluation methods were well established with the same level of advanced countries. In this study, direction of the development for IM of our country was suggested through investigation and analysis of revised test methods and passing criteria.

This study aims to improve methodology for a Defense Simulation which is to calculate wartime stockpile requirement of artillery munitions for K-9 against armored vehicles. Due to incorrect data input and distortion in simulation logic, the expected occupancy ratio for each weapon system obtained from applying a traditional method using an analytical Defense Simulation shows considerable discrepancies from what we expect from a war in the future. This study analyzes causes for incorrect data input and phenomena of distortion in simulation logic. By taking measures to control these phenomena, the study aims to present trustworthy methodology for a Hybrid Defense Simulation which is to calculate wartime stockpile requirement of munitions for ground forces by interaction between a controlled training Defense Simulation model and a analytical Defense Simulation model
