Military research and development has long been one of the main drivers of technological change, especially in industrial countries. The U.S. Department of Defense and NATO countries invest in research and development, pushing the wheel of technological progress in both military and civilian sectors. This article discusses this topic in detail in light of the theoretical concepts, mechanisms, and historical contexts that express this connection. It addresses how military-driven innovations have shaped the fate of industries related to semiconductors, commercial aviation, and information technology, through somewhat detailed case studies alongside quantitative estimates. The article also discusses the more general effects of military research and development on national innovation structures, due to the displacement of private industry innovations and their impact on productivity growth.
The influence of military institutions on technological progress is immense, dating back to the Industrial Revolution. The research and development (R&D) activities sponsored by military institutions, particularly after World War II, have affected numerous civilian industries through generating knowledge spillovers, secondary products, and cost reductions due to military procurement (Mowery, 2010). Several authors, including Nelson (1959) and Arrow (1962), have highlighted the need for public investment in research and development, particularly in mission-oriented research that includes military research. The following details discuss the complex relationship between military R&D and technological innovation, focusing on the U.S. experience and drawing relevant comparisons with other major industrial economies such as France and the United Kingdom.
There is a need for mission-oriented research and development programs that can stimulate innovation in areas characterized by market failures. Both foundational works by Nelson 1959 and Arrow 1962 emphasize that in a world characterized by high uncertainty and long lead times, government-funded R&D projects found to be risky by private firms should be financed. A good example of this is military R&D, as defense inventions are long-term investments typically aimed at achieving specific public welfare objectives such as national security. In other words, military funding is essential to ensure the implementation of long-term research projects that do not typically receive good funding from the private sector (Mowery, 2010).
For instance, the U.S. Department of Defense led mission-oriented research and development. The department's strong focus on development at the expense of basic research shows how military R&D is coordinated to target national defense goals. By facilitating interaction between industry and government, military R&D has become a crucial factor in driving technical improvement in most fields. (Mowery, 2010).
A recurring debate in the field of military technological innovation relates to the effectiveness of military innovation during wartime compared to innovation during peacetime. Both historians and economists cite the idea that war drives rapid technological gains due to necessity (Kaempffert, 1941), while more systematic and expansive research occurs in peacetime. Innovations during wartime often narrowly aim to replicate existing technologies for deployment, thus allowing only minimal room for exploring and implementing revolutionary technological improvements. In contrast, peacetime provides a favorable environment for experimental R&D to flourish in delivering radically new innovations that restructure entire industries (Milward, 1977; Mowery, 2010).
Military-driven innovation became more formalized during the Industrial Revolution. For example, the naval rivalry between Great Britain and Germany led to the production of advanced naval technologies that had significantly strong civilian impacts (Mowery, 2010). During the post-World War II period, military research and development programs in the United States became more institutionalized, meaning that the Department of Defense's activities dominated large-scale R&D projects related to both defense and civilian technologies (Lichtenberg, 1995). Over the centuries, the historical rise of organized military R&D has been emphasized as one of the cornerstones in the development of major technologies, many of which found civilian applications.
The pattern of defense-related R&D spending by major OECD economies, particularly the United States, France, and the United Kingdom, during the period 1981-2005 highlights significant military expenditure. In the United States, an unusually high percentage of the R&D budget is allocated to defense, with more than half of the R&D funded by the Department of Defense performed by industry (Mowery, 2010). For the United States throughout the period covered by the study, the dominance of military R&D within the broader national innovation system gives it weight in shaping civilian technologies. In France and the United Kingdom, there has also been high industrial engagement in defense R&D, with minimal university involvement compared to industrial sectors (Mowery, 2010).
Military R&D affects civilian innovation through the following main channels:
While military R&D has undoubtedly made significant contributions to technological advancement, critics argue that such programs often focus more on performance than on cost-effectiveness, with many leading to inefficiencies outside of civilian markets (Mowery, 2010). Moreover, the focus on high-performance technologies in military R&D may limit their diffusion into cost-sensitive sectors of civilian industry. What is required is a broader economic impact of defense-related innovations, whether the investments in these innovations lead to widespread technological spillover.
Case studies related to military R&D in the post-war U.S. economy provide the best opportunity for understanding the impact on civilian sectors.
The concept of Revolution in Military Affairs illustrates how revolutionary technologies, such as precision-guided munitions and stealth, have changed the nature of warfare. The United States, for its part, developed the RMA model and contributed significantly to advances in military R&D in those technological breakthroughs (Murawiec, 1998). However, several challenges impeded the implementation of the RMA, as some military sectors resisted these changes due to their potential to challenge traditional models of warfare (Murawiec, 1998).
The overall economic impact of defense-related R&D has been fiercely debated. Some researchers argue that defense R&D enhances productivity in the private sector; while others contend that it crowds out private R&D by raising costs for skilled labor and inputs in general (Mowery, 2010). Meanwhile, evidence suggests that military R&D does not necessarily lead to increased productivity, especially when targeting high-performance technologies that have only limited or no commercial potential (Lichtenberg, 1995).
Most military R&D programs are designed for dynamic improvement, meaning that firms increase their spending on R&D as the project progresses. This certainly applies to long-term defense projects where firms change their approach to meet the military's changing needs and the availability of government funding (Rogerson 1995). This type of approach helps maintain the flexibility of military R&D programs and keeps pace with technological developments while committing to achieving national defense objectives.
Indeed, military R&D has been among the strongest drivers of technological innovation in this century - in the United States, defense-related research has shaped entire industries, from information technology to commercial aviation. However, military R&D represents an influential force on civilian innovation, and its impacts on the economy as a whole - such as the crowding out of private R&D - are highly controversial. Nevertheless, military-driven innovation processes have yielded significant technological breakthroughs, many of which have transformed civilian industries. As governments continue to invest in military R&D, understanding how military technologies transfer to civilian markets is crucial for maximizing the benefits of these investments.
