The gravity of Paleolithic hunting

Topographic relief potentially played an important role in Stone Age hunting from the Middle Paleolithic onwards. Natural physical features like arroyos and cliffs, among many others, likely served as traps to stop or hinder animal movement. Yet, the presence of elevation and slope variation on a landscape means that hunters also may have been able to use terrain to hunt from on high. Here, we explored via archaeological experiment how an elevated position would have interacted with projectile weaponry via the force of gravity to influence a missile’s functional efficacy. We assessed the velocity and kinetic impact energy of two Paleolithic projectile weapon systems, the thrown javelin and the atlatl (spearthrower) and dart, at ground level and then at three-, six-, and nine-meter launch heights. The experimental results of the javelin supported our predictions. Velocity and kinetic impact energy increased as launch height increased. Unexpectedly, however, atlatl-propelled darts did not conform to our predictions, not only failing to increase dart velocity or kinetic impact energy as launch height increased but also decreasing both variables’ values. These results suggest that Paleolithic hunting with an atlatl in certain contexts likely came with consequential, and previously undocumented, opportunity costs. Our results also have implications for several aspects of archaeological interpretation in Paleolithic and post-Paleolithic contexts.

Operating itself safely: merging the concepts of ‘safe to operate’ and ‘operate safely’ for lethal autonomous weapons systems containing artificial intelligence

ABSTRACT The Ministry of Defence, specifically the Royal Navy, uses the ‘Duty Holder Structure’ to manage how it complies with deviations to maritime laws and health and safety regulations where military necessity requires it. The output statements ensuring compliance are ‘safe to operate’ certification for all platforms and equipment, and the ‘operate safely’ declaration for people who are suitably trained within the organisation. Together this forms the Safety Case. Consider a handgun; the weapon has calibration, design and maintenance certification to prove it is safe to operate, and the soldier is trained to be qualified competent to make predictable judgement calls on how and when to pull the trigger (operate safely). Picture those statements as separate circles drawn on a Venn diagram. As levels of autonomy and complexity are dialled up the two circles converge. Should autonomy increase to the point that the decision to fire be under the control of an Artificial Intelligence within the weapon’s software then the two circles will overlap. This paper details research conclusions within the overlap, and proposes a new methodology able to certify that an AI based autonomous weapons system is “safe to operate itself safely” when in an autonomous state.

Responsibility Gaps and Retributive Dispositions: Evidence from the US, Japan and Germany

Danaher (2016) has argued that increasing robotization can lead to retribution gaps: Situations in which the normative fact that nobody can be justly held responsible for a harmful outcome stands in conflict with our retributivist moral dispositions. In this paper, we report a cross-cultural empirical study based on Sparrow’s (2007) famous example of an autonomous weapon system committing a war crime, which was conducted with participants from the US, Japan and Germany. We find that (1) people manifest a considerable willingness to hold autonomous systems morally responsible, (2) partially exculpate human agents when interacting with such systems, and that more generally (3) the possibility of normative responsibility gaps is indeed at odds with people’s pronounced retributivist inclinations. We discuss what these results mean for potential implications of the retribution gap and other positions in the responsibility gap literature.

The Asymmetries Generated by New Weapon Systems and Their Role in Achieving Success on the Battlefield. The Impact of HIMARS on the Conflict in Ukraine

The advent of new weapon systems, which integrate the latest technologies, is transforming the battlefield and redefining the character of contemporary modern warfare. The recent armed conflicts in Syria, Yemen, Nagorno-Karabakh, and Ukraine, by their complexity, serve to illustrate the diversification of threats and the adaptation of military capabilities to counter them. Regardless of the type of conflict, success on the battlefield depends on the ability to gain an advantage over the enemy and exploit it. Such an advantage may be derived from the realization of asymmetries on the battlefield, which may be generated at all levels of military operations. The equipping of the Ukrainian forces with the HIMARS system in the summer of 2022 has given them a significant position of advantage, creating a number of tactical and operational asymmetries. In this context, the objective of this research is to identify the asymmetries generated by the HIMARS system and to determine how they contributed to the battlefield success. The key findings are of significant value due to the fact that most NATO member states, including Romania, are making efforts to strengthen their HIMARS capabilities.

On the Growth of Small Cracks in 2024‐T3 and Boeing Space, Intelligence and Weapon Systems AM LPBF Scalmalloy®

ABSTRACTThe desire to use additively manufactured (AM) parts to ensure the availability of military aircraft, and to build limited‐life unmanned aerial vehicles (drones), coupled with the United States Air Force (USAF) approach to the airworthiness certification of AM parts has focused attention on durability analysis/assessment, and hence on the growth of small cracks in AM parts. Previous studies have shown that laser powder fusion built (LPBF) Scalmalloy® has: i) A yield stress and an ultimate strength that are greater than that of AA2024‐T3 and comparable to that of AA7075‐T6; ii) A resistance to crack growth that is better than that of AA7075‐T6 and comparable to that of AA2024‐T3. However, since the ability to predict the durability of a part is essential for its airworthiness certification, the present paper illustrates how to perform a linear elastic fracture mechanics (LEFM)‐based durability assessment of Boeing Space, Intelligence and Weapon System (BSIWS) LPBF Scalmalloy®. The durability study includes specimens with both machined surfaces and surfaces left in the as‐built condition. As a result, it would appear that BISWS AM LPBF Scalmalloy® is an ideal candidate for building limited‐life AM replacement parts for fixed and rotary wing aircraft and drones.

Особенности военно-технического сотрудничества России и Индии: динамика, риски и перспективы партнерства

This article analyzes the specifics of military-technical cooperation between Russia and India, as well as the dynamics, risks and prospects of the partnership in the first quarter of the twenty-first century. In their inter-state relations, the Russian Federation and the Republic of India adhere to the concept of a long-term privileged strategic partnership in the field of security and defense that dates back to the Cold War years. Despite high competition on the military equipment market and a significant increase in military-industrial capabilities in New Delhi, Moscow remains the main supplier of military products to India. The range of Russian military products is quite broad and includes a variety of weapons and equipment to meet the growing needs of India's army and navy. However, there are risks associated with the current dynamics of military-technical cooperation and the increasingly complex geopolitical situation in the region and the world. The article presents the main problems, threats and challenges to bilateral relations in the field of military-technical cooperation, which are associated with India's desire to diversify arms supplies, growth of political and economic risks caused by the sanctions policy against Russia from the collective West, changes in the intensity of geopolitical processes and increased competition from other military suppliers. In addition, prospects for future military-technical cooperation between the two countries are examined, including technological advances, opportunities related to India's Make-in-India program, and potential strategic areas of cooperation between Russian Federation and Republic of India, such as unmanned systems, cybersecurity, and joint research to develop more advanced weapons systems. The bottom line is thatproductive military-technical cooperation between Russia and India can be achieved in the future if a number of measures are taken, mostly related to eliminating risks and creating good conditions for both sides. Such measures could include expanding the boundaries of military-technical cooperation, ensuring mutually beneficial economic conditions, strengthening institutional ties, and bringing together scientific and technical experts in the field.

MAIN TRENDS IN THE USE OF UNMANNED AIRCRAFT IN THE RUSSIAN-UKRAINIAN WAR

One of the features of the russian-ukrainian war was the widespread and rapid use of unmanned aerial vehicles (UAVs). Today, the range of tasks solved with their help is constantly expanding. Mainly – during independent combat work with the possible use of them both in automated troop control systems and autonomously as means of reconnaissance, conducting radio-electronic warfare or for air strikes, as well as means of targeting for high-precision weapons systems, relaying in communication systems "link". The article reviews the development of technologies for the use of UAVs during the large-scale invasion of the armed forces of the russian federation on the territory of Ukraine. A brief description of some Ukrainian-made UAVs has been determined. The most important parameters that must be taken into account before flying a multi- rotor UAV and the methods of their calculation are specified. The further course of events on the battlefield is predicted, taking into account the development of both UAVs and means of radio-electronic warfare. It is suggested that when choosing a rational option for the use of UAVs by the Defense Forces, they should use suitability criteria and mathematical expectation of loss of the combat potential of the enemy's group of troops (forces), taking into account complex radio-electronic conditions. Further research should be directed to the solution of practical tasks of implementing group control in the management of UAVs, which leads to an increase in the efficiency of UAV use. The application of swarms of unmanned systems has extremely high potential for effective execution of reconnaissance and reconnaissance-strike tasks on the battlefield. An important issue in the practical application of UAV swarms is the creation of specialized software for management and control.

Prestige and punishment: Status symbols and the danger of white elephants

This article identifies and unpacks the intrinsic potential for backlash in the pursuit of status symbols. While status loss has been associated with domestic pushback and reduced legitimacy for ruling governments, the literature on status is yet to examine how status-seeking can backfire even when a state can successfully claim to have acquired a status symbol. We contend that status backlashes are an inherent risk of status-seeking due to the multivocality of costly status symbols. Our heuristic framework for studying status backlashes proposes examining modes of critique that construe status symbols as irrational or unjustified costly endeavours, undermining their legitimating capacity and potentially even transforming them into a marker of stigma. Empirically, we identify three modes of critique present in reactions to Brazil’s hosting of the World Cup in 2014 and the Olympics in 2016. There, despite recognizing the symbolic value of hosting these mega-events, Brazilian audiences also criticized the government for the opportunity costs, vested interests and subservience that it entailed. Undertaking two shadow case studies – on the backlash against the United Kingdom’s renewal of its Trident nuclear weapons system and Norway’s engagement in military interventions between 1999 and 2012 – we document how these modes of critique associated with status symbols can travel across contexts.

Lethal Autonomous Weapon Systems: Ethical Dilemmas and Legal Compliance in the Era of Military Disruptive Technologies

Lethal Autonomous Weapon Systems (LAWS) have emerged as one of the most significant advancements in military technology, leveraging artificial intelligence (AI) and machine learning to execute missions without direct human control. As these systems become central to modern warfare, they raise critical questions about their compliance with International Humanitarian Law (IHL) and International Human Rights Law (IHRL). This paper delves into the legal and ethical debates surrounding LAWS with particular attention to the discussions within the Group of Governmental Experts on LAWS (GGE on LAWS). We analyze whether these technologies can adhere to fundamental human rights while maintaining their operational efficacy. Through the application of the Autonomy Spectrum Framework to real-world scenarios, the study highlights both the strategic advantages of LAWS and the risks of dehumanizing warfare. The need for robust legal frameworks to ensure accountability and human oversight remains paramount.

Rectangular Slot based Beam Focusing Dual-Band Phase Gradient Metasurface

This study proposes method for enhancing the performance of previously developed or produced weapon systems without developing new detection equipment by using Phase Gradient Metasurfaces(PGMS). Metasurface has been studied and utilized a lot to improve the detection performance of inorganic systems, but its utilization is low due to its narrow bandwidth and complex structure. To address some of these limitations, dual-band power focusing PGMS is proposed. Its frequency independent unit cell characteristic enables creating metasurface that concentrates signals in dual-band. The designed PGMS was validated through near-field and far-field measurement, confirming signal concentration at the specified focal length and improved gain in the dual bands.

Artificial Intelligence, Warfare and Ethics in India

ABSTRACT In the second decade of the new millennium, artificial intelligence (AI) became a catchword among senior politicians and the military officers of India. Indian military officers have raised concerns about the potential use of AI-enabled weapon systems by China and by insurgents supported by Pakistan in the subcontinent. This article portrays the complex interlinkages between AI, strategic planning about future warfare and the role of ethics in India. The article, divided into three sections, deals with the role of AI and ethics in India’s grand strategy, in military strategy and in command culture. Finally, the article also offers some policy recommendations. For cultural reasons, India follows a defensive strategy. India is attempting to integrate the AI weapons within its dharmayuddha (just war) format. Indian military strategy emphasises that on no account should these intelligent machines be autonomous. Atman (self-consciousness) must not be subordinated to yantras (machines).

How AI Systems Can Be Blameworthy

AbstractAI systems, like self-driving cars, healthcare robots, or Autonomous Weapon Systems, already play an increasingly important role in our lives and will do so to an even greater extent in the near future. This raises a fundamental philosophical question: who is morally responsible when such systems cause unjustified harm? In the paper, we argue for the admittedly surprising claim that some of these systems can themselves be morally responsible for their conduct in an important and everyday sense of the term—the attributability sense. More specifically, relying on work by Nomy Arpaly and Timothy Schroeder (In Praise of Desire, OUP 2014), we propose that the behavior of these systems can manifest their ‘quality of will’ and thus be regarded as something they can be blameworthy for. We develop this position in detail, justify some of its crucial presuppositions, and defend it against potential objections.

Research on Multiphysics-Driven MEMS Safety and Arming Devices.

As the core component of energy transfer in weapon system, safety and arming (S&A) devices affect the safety, reliability, and damage ability of the weapon. Micro-electromechanical systems (MEMS) S&A devices have been widely investigated for their smaller structure size, higher functional integration, and better smart functionality. This paper proposes the design of a multi-physics field-driven MEMS S&A device. The S&A mechanism is composed of a setback mechanism, a spin mechanism, and an electrothermal mechanism, achieving multiphysics-arming. With the coordination of the three mechanisms, the S&A device can produce a 1 mm displacement. The displacement generated allows the S&A device to switch between safety status and arming status. The unlock conditions and overload resistance of each mechanism are obtained by finite element simulation. Based on SOI wafers and silicon oxide wafers, the chips were fabricated and packaged. Several tests were carried out to verify the working condition and overload resistance of the S&A device. The result shows that under a voltage of 11 V and a rotation speed of 8000 r/min, with a size no more than 10 mm × 10 mm × 1.5 mm, the device works smoothly and can withstand an overload of 25,000 g.

Lethal Autonomous Weapon Systems and Automation Bias

Autonomy in weapon systems is already a genuine concern. States try to come up with their own definitions of these systems and pay utmost effort to impose their own understanding of these systems upon other states. For a fairly high number of states barring a total ban on such weapons would be the ideal solution; however, such states that are anxious about the increase in autonomy in war-making capabilities, as adopts a second-best scenario to contain risks created by the deployment of such systems. To this end, placing them under meaningful human control emerges as an important political and legal objective. The author believes that placing autonomous weapons under human supervision, despite its initial promise, will yield negative results. This is due to the fact that humans tend rather to be too willing to follow the solutions generated by autonomous systems. First observed in other industries of civilian nature like aviation or health, automation bias has the potential to negate most if not all of supervision measures expected to ensure proper implementation of international humanitarian law.

National and International Perspectives of the Hungarian Ground-Based Air Defence Forces (2)

Based on the findings of part 1 of my article series, analysing the strategic environment and considering first ideas of multinational capability development options for the Hungarian ground-based air defence forces, the present force structure and already initiated next steps are assessed and remaining capability gaps are identified. It is encouraging to see that prudent procurement decisions can systematically lead the way from a Soviet dominated weapon system landscape to swiftly being on track to becoming one of the most capable ground-based air defence forces nations in Europe and NATO.

Hunting with poisoned arrows during the Terminal Pleistocene in Northern Europe? A tip cross-sectional area assessment and list of potential arrow poison ingredients

The lithic projectile points of the Late Upper Palaeolithic (∼14.7–11.7 ka BP) in Northern Europe display a marked variation in size and design. The small tanged points characteristic of the latest phase in the sequence can be directly associated with finds of arrow-shafts and bow fragments, benchmarking the presence of archery. In the absence of such organic evidence during the older phases, size differences between tip designs may be used, with reference to ballistic principles, to derive hypotheses about ancient weapon systems. By calculating tip cross-sectional area values for a large sample of shouldered, backed, and tanged points from sites across the Northern Europe, we here explore likely changes in weapon use through time. In this context we specifically investigate the likelihood of the smallest of these tips as having been used with poison to increase hunting success. Our results show that: (i) bow-and-arrow technology most likely was in use already during the earliest phases of human occupation in the region; (ii) later on, different weapon systems equipped with different tip designs were used in parallel; and (iii) the smallest of lithic armatures align well with ethnographically documented poisoned arrows. To assist with future studies in the use of arrow poisons in Europe, we provide a list of potential poison sources, where they are currently distributed in the context of our study area.

Feasibility and foundational elements of CBM+ technology application in weapon systems

The maintenance strategies of weapon systems have evolved from corrective maintenance post-failure to time-based preventive maintenance, driven by the growing adoption of diagnostic technologies and data utilization. Currently, there is a transition to Condition-Based Maintenance (CBM) and, where applicable, Condition-Based Maintenance Plus (CBM+). This study investigated the feasibility of applying CBM+ technology using sensor data from weapon systems and explored methods for implementing the related foundational elements. First, the feasibility of CBM+ technology was confirmed by integrating data collection devices into the engine components of selected weapon systems, enabling sensor data collection and monitoring. Second, empirical evidence was gathered on the foundational elements necessary for the broader adoption of CBM+ technology. Practical application methods were proposed based on this evidence, including criteria for implementing CBM+ technology in major operational weapon systems, estimation of sensor data capacity, network methods for data transmission and collection, and the standardization of sensor data. The study’s findings are expected to provide reference points for selecting target weapon systems for the development and application of CBM+ technology, as well as outline essential foundational elements, such as security, networking, and data standardization, critical for leveraging related technologies.
