We reconsider the notion of technological trajectories by means of a detailed case-study of the evolution of tank technology between 1915 and 1945. We use principal component analysis to analyze the distribution of technical characteristics and how they map into specific service characteristics. We find that, despite the existence of differences in technical leadership, tank designs of different countries show a high degree of overlap and closeness along a common technological trajectory. In… 
Dominant design and evolution of technological trajectories: The case of tank technology, 1915–1998
It is argued that the interaction between science, technology, and the social element is responsible for product evolution and that the product evolution process follows continuous changes in the technological trajectory resulting from technological advances in the case of tanks.
Civilian Structures as Military Restrictions
The military community is a secluded part of society and normally has to act on the conditions offered by its civilian surroundings. When heavy vehicles were developed for war, the civilian
Evolution in military affairs in the battlespace of Syria and Iraq
This paper will consider developments in the Syrian and Iraqi battlespaces that may be conceptualised as relevant to the broader evolution in military affairs. A brief discussion of different notions
Dependency of Military Capabilities on Technological Development
This study supplements the previous research and presents a model for the whole process of capability modelling, defined as the probability of a successful task or operation or proper functioning of a system.
The Evolution of Technologies: An Assessment of the State-of-the-Art
Scholars from a wide variety of disciplines who have studied technological advance in some detail have converged on the proposition that technological advance needs to be understood as proceeding
Mapping extended technological trajectories: integration of main path, derivative paths, and technology junctures
An extended technological trajectory method that identifies not only the single main path, but derivative paths emanating from technology junctures on the main path can help researchers better identify technologically related opportunities, thereby triggering the process from well-focused technology portfolio to technological advantages.
Selecting Technological Paradigms: Beyond Push-Pull Dynamics. The Case Of The Artificial Disc
Giovanni Dosi’s technological paradigm theory was developed in part to correct the then dominant practice to focus on either “demand-pull” or “technology push” when explaining technical change. In
Engines of Power: Electricity, AI, and General-Purpose Military Transformations
Major theories of military innovation focus on relatively narrow technological developments, such as nuclear weapons or aircraft carriers. Arguably the most profound military implications of
Evolutionary approaches to technological complexity tend to ignore the role of invention. In this paper, we follow the theory of invention developed by Brian Arthur to trace the emergence of


The Evolution of Helicopter Technology, 1940–1986
The evolution of helicopter technology was analysed by means of the characteristics of helicopter models introduced in the period 1940–1986. An improvement took place in some dimensions of
The Early Development of the Steam Engine: An Evolutionary Interpretation using Complexity Theory
In this paper we analyse the early development of the steam engine as a search process in a multidimensional design space. This perspective allows us to make use of recent insights coming from
The Machines of War: Western Military Technology 1850–2000
From the standpoint of military technology, the 20th century divides between two eras. The first half of the century saw the culmination of the mechanization of armed forces that had begun midway
A Model for Technological Change Applied to the Turbojet Revolution
During the four decades following the Wright brothers' flight, the combination of propeller and piston engine constituted the normal means of aircraft propulsion. In those years, tremendous progress
Military Innovation in the Interwar Period: Armored warfare: The British, French, and German experiences
Tanks had appeared in large numbers only at the end of the Great War. Their first success had come in the Battle of Cambrai in fall 1917. They had also played a major role in the Australian success
Variety and the evolution of refinery processing
A measure of variety, based on Weitzman's maximum likelihood procedure, which indicates the degree of differentiation of a product population, is developed and applied to process characteristics of oil refining.
From innovation to use: Ten eclectic theses on the historiography of technology
Abstract The paper argues that most (Anglo‐Saxon) historiography of technology, including recent sociologically‐oriented work, is concerned with innovation rather than technology, and that there has
Rationality, Agency, Contingency: Recent Trends in the History of Technology
When the Society for the History of Technology (SHOT) launched itself in the late 1950s, many U.S. historians found a compelling postwar framework for organizing research around an American
