Military conflicts and the performance of state-owned enterprises: a study of Ukraine’s aerospace, defense, and electro-engineering industries before and after the 2014 Crimea and Donbas occupation

Abstract This study addresses the under-researched role of state-owned-enterprises (SOEs) in global value chains/production networks (GVCs/GPNs). It examines how the economic performance, foreign trade, and value capture of Ukrainian firms – classified by ownership, position in GVCs/GPNs, size, and diversification of their customer base – have evolved following the Russia’s occupation of Crimea and parts of Donbas in 2014. The study reveals significant differences in the distribution of SOEs, private, and foreign enterprises between the aerospace/defence and electro-engineering industries. Overall, since the Russian aggression in 2014, the aerospace and defence industries have outperformed electro-engineering firms, largely due to strong state support. The study concludes with broader observations that while even intensive mutual trade could not prevent the war, the war does not necessarily lead to a complete cessation of mutual trade.

THE ROLE OF MILITARY TRIBUNALS IN THE FIGHT AGAINST LABOUR DESERTION AT TEXTILE ENTERPRISES OF IVANOVO REGION IN 1942–1943

This article examines the punitive practice of military tribunals against textile workers who committed unauthorised departure from enterprises, as well as production disrupters influential among workers, from November 1942 to November 1943. It became possible after the adoption by the Presidium of the Supreme Soviet of the USSR on October 11, 1942, of Decree ‟On the extension of the Decree of the Presidium of the Supreme Soviet of the USSR” dated December 26, 1941, to workers and employees of enterprises of the People’s Commissariat of the Textile Industry of the USSR. ‟On the responsibility of workers and employees of enterprises of the military industry for unauthorised withdrawal from enterprises.” As a result, textile workers were equated with workers in the defence industry; they were considered mobilised for the period of the war and assigned to permanent work at the textile factories and factories where they worked. The unauthorised departure of workers and employees from work was considered as desertion, and those guilty of committing them (deserters) were sentenced by military tribunals to imprisonment for a term of 5 to 8 years. The article reflects the dynamics of this process, provides data on deserters by profession and sex; we call preventive measures on labour collectives, etc. Attention is paid to such positive practice of the tribunals as conditional conviction with the obligation to return to the enterprise. It was prepared on the materials of the State Archive of Ivanovo Region, which had first been introduced into scientific circulation. It is addressed to specialists in the field of the history of Soviet textile industry, to graduate students, undergraduates and students of higher educational institutions.

Healable, Recyclable, and Ultra-Tough Waterborne Polyurethane Elastomer Achieved through High-Density Hydrogen Bonding Cross-Linking Strategy.

With the increasing popularity of elastomers in industry and daily life, their high performance and functionality have attracted widespread attention. However, it is a great challenge for them to possess both high mechanical properties and excellent healing and recovery capabilities due to the limitations of the preparation methods and the intrinsic microstructure of the elastomers. In this study, a strategy of ice-controlled interfacial stepwise cross-linking was proposed to prepare the waterborne polyurethane-based elastomers with ultrahigh-density hydrogen bonding interaction achieved by enhancing the utilization rate of phenol hydroxyl groups of tannic acid to the maximum extent. The elastomers have incredible mechanical properties, including ultrahigh toughness of 1.03 GJ m-3 (which represents the highest level among polyurethane elastomers prepared through common processing techniques to date), extremely high true fracture stress of ∼1.9 GPa, world-record fracture energy of 520 kJ m-2, and exciting multiple functional characteristics, such as highly efficient self-healing ability of 10 min, high resistance to physical damage and chemical corrosion, broad temperature and frequency damping effects, good shape memory effect, and excellent melt-processing recyclability and solvent recyclability. These robust multifunctional elastomers represent considerable potential in various fields, from defense and military industry and civil transportation to precision manufacturing, etc.

Enhancing aviation safety: Multifunctional graphene nanostructured foams for lightweight fire suppression materials

Fuel tank fires and explosions are the primary causes of military and civilian aircraft losses and have been a major concern for the aviation and defense industries. Passive protection systems with explosion-suppression materials generate a protected environment within fuel tanks before ignition can occur and help prevent catastrophic failures. To minimize these concerns, open-cell reticulated polyurethane foams are extensively used in passive protection systems. However, fire- and explosion-related incidents are still taking place and need to be urgently addressed for aviation safety. This study investigates the effects of graphene nanostructured foams for redesigning the next-generation lightweight fire-retardant materials in aviation. Graphene foams have a unique open-cell morphology with three dimensional (3D) continuous and interconnected network structures and hollow features, which can be suitable for aircraft and defense applications. In this study, mechanical and thermal characterizations tests were conducted on graphene nanostructured foams for a better evaluation. Mechanical loading-unloading studies highlighted their outstanding mechanical energy-absorption capabilities against external loads. The thermogravimetric analysis revealed that the graphene foams provided excellent thermal properties against fire and high-temperature degradation. It was also confirmed that graphene foams uniquely manifested self-extinguishing characteristics during burning tests without catching fire or dripping for secondary fire formations. According to the tube explosion experiments, the graphene foams kept their appearance and strength after blast impacts and elevated explosion temperatures and shock waves. As a result, the proposed multifunctional graphene micro- and nanofoams offer significant potential for the next-generation fire- and explosion-suppression materials in various critical industries, such as aircraft, defense, space, drone, energy, and automotive.

3D printing of cordierite glass-ceramics

Compared to traditional ceramic materials, glass-ceramics can also exhibit superior properties and are now widely used in cutting-edge national defense industries technology, aerospace, electronics, construction, and other fields. In this study, it is for the first time reported that novel photopolymerization 3D printable slurries using cordierite glass ceramic powder were prepared. The effects of slurry properties and printing process parameters on the warpage of the printed samples were studied. Cordierite glass-ceramic parts fabricated using photopolymerization 3D printing and heat treatment processes were studied to evaluate the effects of sintering parameters on the properties of the samples. The obtained additively manufactured cordierite glass-ceramics exhibit excellent microstructural and mechanical properties, with a maximum bending strength of 181 MPa, an increase of 95.66 % compared to that of the previously reported 3D printed cordierite ceramics. The underlying mechanisms of the glass and ceramic phase characteristics influence the density and the mechanical properties during and after the courses of sintering were also investigated and unveiled in detail. This study provides a viable method for manufacturing complex-shaped cordierite glass-ceramic components using 3D printing.

A Review on the Gas‐Phase Modeling Study of Aluminum Combustion in Various Environments

AbstractAluminum combustion is an area of intense research due to its wide‐ranging applications in the aerospace, automotive, energy storage carrier and defense industries. Gas‐phase reaction mechanism plays an important role on the prediction of the combustion intermediates and final products, which can significantly affect the combustion heat releases and combustion organization forms. In recent years, researchers have developed some gas‐phase reaction mechanisms to predict the combustion phenomenon and behavior of aluminum in different environments. This review aims to provide an overview of the current state of the art in gas‐phase modeling study on aluminum combustion with various oxidizers, including oxygen, steam, carbon dioxide and so on. The primary oxidation reactions of aluminum were concluded, and the rate coefficients of these reactions were also reviewed and compared in this work. Besides, the simulations by using the gas‐phase reaction mechanisms were reviewed and the main oxidation reaction pathways of aluminum with various oxidizers were analyzed based on modeling analysis results. Combining phase change reactions and surface reactions, gas‐phase reaction mechanism will become more important for prediction the combustion speed, combustion temperature and combustion mode of aluminum in future.

Analysing the European Defence Fund’s financing distribution across EU countries: what drives national participation in defence-industrial integration projects?

The establishment of the European Defence Fund (EDF) marks a significant shift in how EU Member States approach the integration of the defence industry as it aims to systematically promote inter-European defence-industrial cooperation across national defence sectors. However, there is a lack of empirical evidence of the actual dynamics regarding EDF implementation. While there are accounts of EU countries’ varying political positions on defence integration, including its industrial aspect, it remains unclear whether Member States’ actual participation in integration projects aligns with these positions. Are national motives consistent once effective defenceindustrial integration is underway? The findings, based on Masson’s (2024) data on by-country distribution of EDF project financing (2021–2022), present a more nuanced picture of EU countries’ effective engagement with defence-industrial integration than anticipated by the political perspective. While there is a positive relationship between participation in the EDF and defence market size, strategic culture does not influence EU members’ involvement in the Fund. Furthermore, while liberal economicindustrial governance is negatively associated with national participation in EDF projects, a country’s institutional quality has a significant positive relationship with it. This article reveals more complex dynamics of EDF implementation than suggested by the political perspective on defence-industrial integration pre-EDF.

Effect of Drilling Parameters and Tool Diameter on Delamination and Thrust Force in the Drilling of High-Performance Glass/Epoxy Composites for Aerospace Structures with a New Design Drill.

Real service requirements of the assembly performance and joining properties of design components are critical for composite usage in the aerospace industry. This experimental study offers a novel and comprehensive analysis of dry drilling optimization for glass-reinforced, high-performance epoxy matrix composites used in aerospace structures, focusing on thrust force and delamination. The study presents a first-time investigation into the combined effects of spindle speed (1000, 2250, 4000 and 5750 rpm), feed rate (0.2, 0.4, 0.6 and 0.8 mm/rev) and tool diameter (3 and 5 mm) using a custom-designed drill tool specifically developed for this application, filling a gap in the current literature. By employing the Taguchi design of experiments, the study identified that medium spindle speeds (2250-4000 rpm), lower feed rates (0.2 mm/rev) and smaller tool diameters (3 mm) provided optimal conditions for minimizing thrust force and delamination. These results present actionable insights into improving the structural integrity and performance of drilled aerospace-grade composite components, offering innovative advancements in both the aerospace and defense industries.

Assessing the Diffusion of Military Power Capacity of Middle Powers: The Case of Turkey

ABSTRACT Great powers’ military power diffusion (MPD) is superior to Middle Powers (M.P.) in technology acquisition, military innovation, and state & financial capacity. However, M.P.s have started to enhance their MPD thanks to their growing impact on international politics. In this vein, this paper aims to offer an alternative explanation of MPD by introducing a novel theoretical framework, Military Power Diffusion Capacity (hereafter MPDC), to assess how M.P.s’ MPD influences the balance of power and warfare at both regional and international levels. In doing so, this article is structured into three sections. First, we investigate the existing theoretical frameworks on military power diffusion and the spread of military power by middle-ranking states. Second, we examine the historical evolution of Turkey’s defence industry. Third, we introduce our MPDC framework and test it to the Turkey’s case. Here, we propose a five-layered MPDC framework based on the following determining factors: 1) Sustainable Financial & State Capacity, 2) Geopolitical and strategic rivalries, 3) Domestic conditions, 4) Civil-Military bargaining levels, and 5) regional and global power status-driven aspirations. Then, we scrutinize Turkey’s MPDC since the 1990s within our five-layered framework to assess the implications of its MPD on the changing international security environment.

Translating agile management practices into a traditional industry context

AbstractThis study explores the translation of agile management practices (agile) into a traditional industry context. Using a case study of agile adoption in a development project in a large traditional company of the aerospace and defense industry, this research investigates how the translation process unfolds by studying how both idea and context are adapted to create shared meaning. This research makes two main contributions. First, this research introduces translation theory to the innovation management literature and details its applicability in explaining variations in outcomes of applying management practices in new organizational contexts. Our research suggests that this constitutes a complementary theoretical lens to diffusion theory, enabling the explanation of the process to create shared meaning when idea and recipient context have a low level of compatibility. Second, this research shows the process of translating agile into a traditional context through a non‐linear joint creation of meaning. The process was shaped largely by the experience and resolution of project‐external (i.e., with the surrounding organization) and project‐internal conflicts, which in turn motivated the idea or context to adapt. The study identifies two central concepts, namely isolation, and shielding, which determine how the translation process unfolds and how meaning is created. Managerial implications based on these contributions are presented and discussed.

Recovery of Low-Concentration Tungsten from Acidic Solution Using D318 Macroporous Resin.

Tungsten is a crucial strategic metal that plays a significant role in various fields, such as the defense industry, fine chemicals, and the preparation of new materials. During the practice of numerous tungsten smelting processes, a large amount of acidic wastewater containing low concentrations of WO3 is generated. The adsorption method, known for its simplicity, effectiveness, and ease of operation, represents the most promising approach for tungsten recovery and is vital for the sustainable development of the tungsten industry. In this study, D318 macroporous resin was used as an adsorbent to investigate its effectiveness in adsorbing WO3 from acidic solutions. Static adsorption experiments revealed that the adsorption capacity of D318 resin for WO3 was 683 mg·g-1. Kinetic analysis indicated that the controlling step for the adsorption of WO3 from acidic solutions by D318 resin was intraparticle diffusion. Thermodynamic analysis demonstrated that the adsorption process was endothermic and could occur spontaneously. By fitting the isothermal adsorption equation, it was found that the Langmuir model was more suitable for describing the adsorption process of WO3 on D318 resin in acidic solutions. The results of dynamic adsorption experiments showed that under optimized conditions, the dynamic adsorption capacity for WO3 was 529 mg·g-1; when using NaOH as the desorbent for cyclic desorption, the desorption rate for WO3 was 98.21%. XPS and SEM-EDS testing and analysis confirmed that D318 macroporous resin exhibited excellent adsorption performance for tungsten in acidic solutions.

The Beowulf Group: Taking the lead to defend Europe

Russia’s full-scale invasion of Ukraine has exposed divisions in European strategic culture and threat perception. The search for a lowest-common-denominator response to the threat has hampered the European reply to the Russian aggression, often forcing the EU to move at the speed of its slowest member, whether in supplying ammunition and equipment to Ukraine or setting up the defence industry needed to accelerate such a supply in the future. Notwithstanding the importance of keeping a broad coalition together, this article argues that it is now time to create a vanguard of like-minded European nations, led by France, Poland and, though not an EU member, the UK, but open to other states, which can force the creation of a new strategic culture able to meet the Russian threat. This ‘Beowulf Group’, named after the Danish hero from the Anglo-Saxon epic who stood up to the marauding monster Grendel, could establish a Strategic College for Europe, a joint Elite European Reserve Legion and a strategic communications centre, to move European policy in a more active direction.

Maverick or Front-runner? Army Modernization in Hungary in the Light of the Other Visegrad Countries

This article compares Hungary's defence modernisation policy with that of the other Visegrad countries and finds that Poland has invested the most in developing its military capabilities and, together with the Czech Republic, has benefited considerably from rising international demand stimulated by the war. Both combined the purchase of modern equipment with the award of government contracts to local suppliers. Slovakia followed the same pattern, but without significant export capacity. Hungary, on the other hand, was unable to prevent the collapse of its former defence industry. As a result, its current development programme uniquely integrates the goals of army modernisation with the plan for rebuilding the sector, which relies heavily on the participation of large European companies, whose role is less important in the other countries. Two other distinctive features of the Hungarian modernisation policy are its embeddedness in broader economic and regional policies, and the creation of six distinct territorial clusters where the reorganisation of the sector is taking place.

Implementation Of Indonesia's Defence Economy Through The Defence Budget Sector

The implementation of military spending through the Indonesian defense industry has shown gradual positive development, driven by efforts to establish an independent defense sector. This study examines the role of Indonesia's defense budget in supporting national security and fostering economic growth, focusing on the collaboration between state-owned enterprises (BUMN) and private companies (BUMS). The defense budget is applied progressively to balance the country's limited resources and the relatively low level of external threats. Using a qualitative research method, this study analyzes data from relevant literature, reports, and policies to evaluate the impact of the defense budget on the Indonesian economy. The research explores key aspects such as the gradual development of defense equipment, the role of research and development (R&D) in driving innovation, and the partnership between public and private sectors to strengthen the local defense industry. The results indicate that Indonesia's defense budget has steadily increased over the past decade, contributing to economic growth, particularly in the manufacturing and technology sectors. However, the overall impact on the economy remains mixed due to challenges such as bureaucratic inefficiencies and dependence on imported materials. The discussion highlights the potential for defense R&D investments to generate spillover effects into civilian industries and recommends strategies to enhance the efficiency of defense spending. In conclusion, the implementation of defense economic policies has laid a strong foundation for the development of an independent defense industry in Indonesia. The study suggests that a gradual increase in defense spending, combined with strategic partnerships and innovation, can support both national security and economic stability in the long term

Novel Bis(4-aminophenoxy) Benzene-Based Aramid Copolymers with Enhanced Solution Processability.

Aramid copolymers have garnered significant interest due to their potential applications in extreme environments such as the aerospace, defense, and automotive industries. Recent developments in aramid copolymers have moved beyond their traditional use in high-strength, high-temperature resistant fibers. There is now a demand for new polymers that can easily be processed into thin films for applications such as electrical insulation films and membranes, utilizing the inherent properties of aramid copolymers. In this work, we demonstrate two novel aramid copolymers that are capable of polymerizing in polar organic solvents with a high degree of polymerization, achieved by incorporating flexible bis(4-aminophenoxy) benzene moieties into the chain backbone. The synthesized MBAB-aramid and PBAB-aramid have enabled the fabrication of exceptionally thin, clear films, with an average molecular weight exceeding 150 kDa and a thickness ranging from 3 to 10 μm. The dynamic mechanical analysis (DMA) and thermogravimetric analysis (TGA) reveal that the thin films of MBAB-aramid and PBAB-aramid exhibited glass transition temperatures of 270.1 °C and 292.7 °C, respectively, and thermal decomposition temperatures of 449.6 °C and 465.5 °C, respectively. The mechanical tensile analysis of the 5 μm thick films confirmed that the tensile strengths, with elongation at break, are 107.1 MPa (50.7%) for MBAB-aramid and 113.5 MPa (58.4%) for PBAB-aramid, respectively. The thermal and mechanical properties consistently differ between the two polymers, which is attributed to variations in the linearity of the polymer structures and the resulting differences in the density of intermolecular hydrogen bonding and pi-pi interactions. The resulting high-strength, ultra-thin aramid materials offer numerous potential applications in thin films, membranes, and functional coatings across various industries.

The Concept of Building an Integrated Digital Ecosystem to Improve the Quality of Products and Services of Defense Industry Enterprises

Research and development of systems for managing material, technical, and intellectual resources are key directions for improving manufacturing processes in the modern world. In recent years, the question of integrating various management systems has become particularly relevant due to the widespread adoption of quality management systems and their certification to meet current regulatory requirements. This study attempts to merge the advantages of using product lifecycle information support technologies, such as data and information management, with the concept of digital twins, including virtual design, digital product modeling, and real-time analysis. The analysis covers the constituent elements of the generalized product design and manufacturing process, addressing the construction of an integrated digital ecosystem to enhance the quality of products and services in the defense-industrial complex. This ecosystem is based on the integration of technologies for continuous product information support using their digital twins and an integrated quality management system. It is shown that the approach to evaluating the effectiveness of purposeful processes should be complemented by a risk-oriented model, which includes response scenarios to potential adverse effects of the operation of the purposeful organizational-technical system. A structural scheme and formalized description of a generalized product information support model are presented, allowing for the integration of specific quality indicators into a unified strategic outcome. Ultimately, a concept for building an integrated digital ecosystem for defense-industrial enterprises is proposed, aimed at enhancing the overall quality of products and services.
