The purpose of this investigation is to present the protection systems used against the low, slow, and small (LSS) unmanned aerial systems (UAS) capabilities. The results of a market survey are included that highlights potential commercial entities that could contribute some technology that assists in the detection, classification, and neutralization of a LSS UAS. In order to accurately select a protection system which will later be used by all Lithuanian Armed Forces units the nine existing protection systems were analyzed. The analysis was done under the technical specifications for acquisitions and the detailed requirements of the measures were set out on the basis of the Operational Requirements Document. This article provides the existing protection systems against unmanned aircraft vehicle (PSAUAV) technical conditions analysis with the aim to help to make the choices in defining a protection system that can be adaptive to contemporary and future needs for the Lithuanian Armed Forces. The numerous requirements and expectations for nine PSAUAV were analyzed by statistical software package SPSS version 20. There were used the experts’ evaluation methods based on experts’ surveyed sample analysis. The Kendall’s coefficient of concordance (W) was selected for quantitative assessments of experts’ decisions data analysis. In addition for PSAUAV technical conditions evaluation was used the hierarchical clustering.
Replacing chemical propellant and using electric power that generate the muzzle power to propel the rocket is done since 1846. There were productive research conducted to achieve velocity of 2000-3000 m/s, which cannot achieved using conventional propellant. These velocities are capable of penetrating the armor vehicles and high-density materials. Research is conducted to increase the velocity and stealth technology to penetrate missile defense system. However, the advanced technology capable of detecting from small drone to high velocity missile. This research give the conceptual design of the two-staged missile capable penetrating the defense shield using only kinetic energy by unconventional propulsion system. One stage act as the prey to the incoming missile and other system enter the shield with its velocity higher than any other interceptor missile. This missile uses Lorentz force to propel the projectile towards the target.
The defense budgets of the Member States of the European Union are rising due to the current economic situation and change in the level of security. The goal of approaching two percent of gross domestic product will probably be reached within one decade. However, the positive trend in the development of the defense budget w ill not allow small states to acquire the exact numbers of military techniques in the numbers that imply a continuous increase the capacity of national armies. Pooling and sharing is one of the approaches that will allow the required capabilities of national armies to benefit the European Union, or the North Atlantic Alliance. Deepening co-operation in the field of acquisitions will put pressure on coordination of activities, alignment of legislation and, above all, overcoming national and common. Obviously, given the current combat experience, the issue of armed forces has already been partly solved and pooling & sharing implementation is a political issue.
The protection of state security by the legal standards of the criminal law is one of the key, the legally protected interests including the cybersecurity in the sectors of critical infrastructure transport (road, air transport, ship, and rail), electronic communications, energy, information and communication technologies, post, industry, water and atmosphere, health. Today’s empirical empowerment confirms that the security is a significant multidimensional factor of the quality of society and citizen’s life, which we have to systematically examine, forecast and ensure. The contribution presents the defined security interests of the state in the framework of new strategic documents of the Slovak Republic in the comparison with the current standards of the criminal law for the protection of state security within the material and non-material components of the defence potential of the state.
Security management in the air transport is understood as an integral part of the activity and the decision-making process of the managers of the air operator and the security service, assigned to manage the security risks in the following dominant areas. The scientific cognition, investigation and complex education in the field of the situational security management within the range of a multidimensional relation “Human – Technique – Environment” in the transport that is perceived as a complex adaptive ergatic system within the context of available resources, it represents a creative activity in the field of security, quality and effectiveness of processes of the personnel education, performance and flight operation provision.
This contribution deals with modelling of military expenditure and its potential security and economic determinants by an Autoregressive Distributed Lag (ARDL) model. This approach is applied to several NATO member countries over the period 2001–2016, namely to Visegrad group countries and Baltic states. Time series of military expenditure (database SIPRI), the risk of inflation, GDP growth, terrorism, foreign pressure, cross-border conflict and ethnic tension (database of Political Risk Service Group) are used in analysis.
The knowledge of basic meteorological parameters is crucial in terms of understanding the atmospheric behavior for a given period and consequently also for creating the weather forecast. There are several ways of obtaining such data. A broadening of measurement techniques through the unmanned aerial vehicles (UAV) is one of the newest trends of today. Depending on the character of use of the unmanned platform, it could gather data from a significant part of low troposphere. Our experiences and problems with meteorological application of UAV is described in this paper.
Postmodernity as a concept of contemporary society together with technological progress and globalization caused changes in orientation of values as well as the transformation of individual and collective identity. Thus, increased vulnerability, both of individuals and society, caused the character of threats to national security. The aim of the article is to analyze the contemporary threats to national security as a phenomenon of a postmodern society, emphasizing the crisis of values as well as of the identity. Postmodern threats forced to revise traditional point of view on the concept of national security and demands to be based on comprehensive approach on the issues of security and defense. This article is an attempt to make an analysis on the topic of national security in an interdisciplinary context. After analyzing the actual threats to the security of the Republic of Lithuania, it was determined that the interaction of many of these threats with the crisis of values is evident. This allows to confirm the importance of further discussions and scientific research on the issues of values and identity in context of national security in postmodern society.
The problem of national security is relevant to all countries of the world as it is an important condition for the country’s economic growth. This is confirmed by the World Economic Forum (WEF) distinguished risks of economic development, their interactions, threats and dangers on the global level. The aim of the article is to characterize the internal factors of Lithuanian national security which are related to the possibilities of economic threats and dangers. The method of basic indicator comparison is used; where as the first year (e.g., year 2007) of the analyzed period is selected as the base year. Both absolute and relative quantities of analyzed indices are compared.
Significant changes to security environment make military operations more complex and demanding. Preparing military commanders to face future challenges has been vital for military success and national security. While the system of the Professional Military Education seems good, there are opportunities to make it more responsive and efficient. The article summarizes the ongoing discussion on the Professional Military Education, and identifies challenges related to preparation of future commanders. Based on recent developments some ideas on improving Professional Military Education are offered.
