A study on the application of RMF for weapon systems in Korea

With the advent of the Fourth Revolution, military weapon systems are also being advanced. In particular, as the proportion of software embedded in these weapon systems increases, the cyber vulnerabilities of advanced weapon systems also gradually increase. If cutting-edge weapons stop abruptly or malfunction owing to software defects or cyberattacks, they will adversely affect defense security as well as combat power and economic losses. The U.S. DoD is implementing the risk management framework (RMF) to cope with cyber vulnerabilities and threats. RMF is a risk management (RM)-based framework that classifies the cyber vulnerabilities of weapon systems based on data and evaluates them according to confidentiality, integrity, and availability. The application of RMF to the Korean military's weapon-system acquisition procedure is still in its infancy. In this study, we studied the application of the RMF to weapon acquisition processors in the U.S. DoD and suggested that measures of availability, reliability, and safety that can affect weapon performance should be managed with security, and that security systems should be applied to reliability, availability, and maintenance (RAM).

Experimental Study of Automatic Weapon Vibrations when Burst Firing

The article presents a new approach to finding the dynamic characteristics of automatic weapons, mainly in case of burst firing. The experiments were tested out on a 30 mm AGS-17 grenade launcher mounted on a tripod in the event of a shot. The obtained results are the basis for evaluating the firing stability of an automatic weapon when burst firing, which allows modernising the existing weapons and evaluating similar weapon systems. Furthermore, the outputs can be used to validate a dynamic model of an automatic weapon system mounted on the tripod. The procedure can be used as an example of practical technique and methodology for other weapon systems.

A Conversion Protocol for 2W Telephone Signal over Ethernet in a Private PSTN

In this paper, we proposed a protocol to convert 2W telephone analog signals to Ethernet data in a private PSTN 2W tactical voice system. There are several kinds of operational problems in the tactical telephone network where 2W telephone copper lines are installed hundreds of meters away from the PBX in a headquarter site. The reason is that it is difficult to install and maintain the 2W telephone copper cable in severe operational fields and to meet safety and stability operational requirements of the telephone line under lighting and electromagnetic environments. In order to solve these challenging demands, we proposed an efficient method that the 2W analog interface signals between a private PBX system and a 2W telephone is converted to Ethernet messages using the optical Ethernet data communication network already deployed in the tactical weapon system. Thus, it is not necessary to install an additional optic cable for the ethernet telephone line and to maintain the private PSTN 2W telephone network. Also it provides safe and secure telecommunication operation under lightning and electromagnetic environments. This paper presents the conversion protocol from 2W telephone signals over Ethernet interface between PBX systems and 2W telephones, the mutual exchange protocol of ethernet messages between two converters, and the rule to process analog signal interface. Finally, we demonstrate that the proposed technique can provide a feasible solution in the tactical weapon system by analyzing its performance and experimental results such as the bandwidth of 2W telephone ethernet network and the transmission latency of voice signal, and the stability of optic ethernet voice network along with the ethernet data network.

Autonomous Weapon Systems In International Humanitarian Law – Simply Just Another Weapon System

<p>This paper reviews the arguments made by the opponents of the utilization at all of so called autonomous weapons (killer robots), on the basis of alleged inherent non compliance with certain cardinal principles of IHL, against the argument that said weapons or systems, and their use, can be satisfactorily accommodated under existing IHL. It gives an overview of the issues identified by the opponents and the main arguments made in favour of banning autonomous weapons. The author looks at the characteristics of two weapon systems and concludes there are already fully autonomous weapon systems in non contentious use. The author submits that the concerns of the banning authors are not rational, the purported distinctions made between certain weapon systems cannot factually and consistently be maintained and are based on the averred existence of categories of weapons that do not exist. Finally, the author argues that the opponents’ concerns and arguments are in the main and based on the normal uncertainties, inherent in all factually to be determined situations and also on slippery slope reasoning. The author emphasises the established rules of IHL and opines that the same are adequate to regulate the so called autonomous weapons and weapon systems and any liability arising from their use.</p>

Modeling and Simulation of Ship-Borne Weapon Stabilization System Based On Double Position Loop Control

In order to solve the problem of increasing system cost and low control accuracy by adding gyroscope or inertial navigation system, a dual position loop control ship-borne stabilization system is proposed in the paper. The mathematical model is established to analyze the influence of ship rolling factors on the space pointing of single position loop weapon system. On this basis, the control strategy of double position loop is proposed, and the simulation structure and control method of inner position loop and double position loop are described respectively. The simulation results show that the method can isolate the factors of ship rolling, realize the closed-loop stabilization control of weapon system in geodetic coordinate without adding system hardware cost, and have good control effect as well.
