Wartime demand for food, medical supplies, and essential military hardware, like circuit boards or munitions, would require navigating significant logistics challenges. It would involve surges in demand for products, requiring new sources of supply and global production. It would also require tracking billions of items through data-driven technologies, like radio-frequency identification tags, to better align inventory with demand. It’s also probable that wartime demands could lead to workforce shortages and the need to produce new products and services quickly. In a war with a peer adversary, logistics and maintenance activities would also be prone to attack by cyber and other more traditional military means.1 None of these assumptions would be trivial logistical tests, to say the least.
However, these challenges are not completely unprecedented. Setting aside adversary disruption, commercial food, health care, and technology companies dealt with each logistics challenge described above during the COVID-19 pandemic.2 While enemy attacks on logistics would be a driving factor influencing how militaries might adjust to these challenges, recent lessons from commercial companies suggest dealing with wartime demand for supplies likely doesn’t require entirely new or monolithic solutions. Additionally, improving logistics practices before a conflict can improve wartime resilience as well.3
Digital technologies are changing warfare, similar to how they have changed modern supply chains, maintenance, and logistics practices. Today’s hyperconnected digital world has changed the character of warfare in part by extending its reach and increasing its speed. Missiles travel farther and faster, while cyber and information capabilities have, in some ways, reduced the significance of distance.
These new features of warfare can give a military a significant advantage. While much of today’s digital battlefields will enable greater speed and reach, distance and geography still matter—people and supplies can’t be delivered over fiber optic cables, nor can factories be moved or duplicated quickly. Ultimately, the latent value of speed and reach in warfare only matters if a military can produce and deliver required military capabilities and supplies despite logistical disruptions.
To better optimize their operations, militaries need to develop practices predicated on the following:
Logistics is the life support of combat. Without the ability to supply troops and maintain equipment, it’s doubtful a military could sustain combat operations. In a peer fight, success may depend on which side can most effectively deprive their adversary of resupplying and maintaining forces beyond the initial outbreak of hostilities. Moreover, the longer a war between peers persists, the more costly it becomes for all sides. Consequently, it’s likely that in a war with a peer, the aggressor would try to win through quick, decisive actions that, among other objectives, would target logistics hubs and routes.4
Deterring such a fight, therefore, can require developing a logistics system that makes an adversary question their ability to starve its opposing force of supplies and maintenance. Figure 1 details a hypothetical scenario where logistics is contested from origin to destination. If a peer aggressor isn't confident that they can quickly and decisively win the conflict, they may question whether the war is worth the cost. Developing a deterrent logistics system during peacetime is crucial to enable better response and readiness in a crisis or competition. This way, the military can be prepared to respond in any situation.
After decades of changes predicated on cost savings and time efficiencies, commercial and military supply and logistics practices may not be that difficult to disrupt during a war with a peer.
The pandemic exposed the fragility of commercial practices that produce and move materials and products. Although militaries have their own logistics capabilities, there is overlap with the private sector in areas such as railways, airports, seaports, and the increasing significance of commercial technologies in modern warfare. Additionally, using automated inventory algorithms that prioritize inventory choices based on logistical normality rather than risk is an important industry practice that intersects with military operations.5 A war with a peer will likely require mobilizing the nation to respond, somewhat like the national responses to the pandemic. To be sure, militaries can make their own decisions to shore up logistics, but dependence on industry for many essential capabilities and resources will persist (and they should).
For militaries worldwide, the private sector is often an essential part of logistics. However, relying on the private sector can expose national supply chains and logistics to vulnerabilities that can also affect military operations. A vulnerability associated with supply chains and logistics practices optimized for efficiency is that minor disruptions can reverberate across industries and supply lines more easily. When the Suez Canal was blocked by a stuck ship, the logistics repercussions were felt around the world and cost tens of billions of dollars and weeks of delays.6 Similarly, when labor shortages slowed semiconductor production, numerous industries felt the consequences to the tune of approximately US$240 billion in a single calendar year (2021) in the United States alone.7
The disruptions from the pandemic or shipping accidents were unforeseen and resulted in considerable global ramifications. Given the fragility of many supply chains and logistics practices, the concerted effort to disrupt them during a war with a peer would likely result in greater disorder for industry and military logistics alike.
The pandemic has led governments to adopt innovative methods for developing and delivering resources. In the United States, Operation Warp Speed was the program coordinated by the United States Department of Health and Human Services and the Department of Defense to expedite the development and delivery of vaccines. This initiative involved producing a variety of vaccines, earlier ramp-up of production by vaccine companies, and faster data collection compared to standard vaccine development procedures.8
While Operation Warp Speed shows that there are alternative ways of producing and delivering critical items, military logistics face some unique challenges. For example, defense industrial capacity has shrunk in recent years (as noted in the companion article, Out with the defense industrial base, in with the defense industrial network). Due to a focus on cost savings, the military has shifted many of its supply sources offshore. As a result, many suppliers and parts of the industrial base only have enough capacity to meet the demand during peacetime, with little flexibility to rapidly increase production during times of crisis or warfare.9
Fragile commercial practices combined with limited military capacity to surge production may leave many militaries vulnerable to wartime disruptions. Sophisticated cyber and electronic warfare attacks reserved for the high stakes of warfare, striking logistics and maintenance facilities through air or maritime military operations, dis- and misinformation campaigns designed to impede workforces, and other means are likely to be persistent wartime threats capable of exploiting existing supply chain, logistics, and maintenance fragility. Blunting the consequences of military attacks on logistics requires thinking differently about logistics.
If supply chain and logistics fragility is caused by emphasizing efficiency, then shifting practices toward effectiveness can offer a solution. More effective practices would ideally prioritize resilience over cost-effectiveness and speed, and industries, governments, and militaries are already taking steps to develop more robust and effective approaches.
In the United States, the effort to modernize military logistics is underway. Joint warfare concepts describe the challenges of operating in “contested logistics” environments, and the US Army has created modernization teams to develop new logistics capabilities, and US military leaders are championing new logistics practices in public statements.10 These efforts are predicated on assumptions that logistics will be critical and a target in theater and at home.11 The solutions involve various elements, like a better use of data, anticipating requirements more quickly, building relationships with global sources of supply, and better integrating logistics capabilities.12
Similarly, Australia’s Department of Defence outlined in its National Defence: Defence Strategic Review 2023 that “optimal Defence logistics network must be resilient through disaggregated and dispersed mutually supporting nodes that enhance redundancy and survivability.”13 The document also notes the importance of integration at the national and global levels to access the “full range of logistics ... effects required by defence,” and to meet maintenance, manufacturing, and storage needs.14
India is also heavily investing in the coproduction of defense capabilities with friendly countries, which provides inherent advantages in building resilience through distributed production for both acquisition and sustainment. For example, the M777 Ultra-Light Howitzer is in service with the United States, Canada, Australia, and now India. The Indian Army’s procurement of Howitzer also includes private sector integration through shared industry assembly of the equipment in India.15 Similarly, the multirole C-295 aircraft used by the Indian Air Force is being manufactured in India through collaboration between industry partners.16 Aircraft engines are also part of coproduction efforts between the United States and industry partners.17
The US-India defense cooperation continues to expand with the implementation of the Logistics Exchange Memorandum of Agreement, Communications, Compatibility and Security Agreement, and the Industrial Security Agreement.18 These agreements allow for enhanced cooperation based on the exchange of information and data. India is also adopting more digitally defined and integrated logistics practices that offer increased efficiency over older, often industrial-age approaches.19 India’s efforts reflect an appreciation for a logistics system that is globally integrated and cooperative.20
The push to modernize sustainment practices, like logistics, isn’t unique to the United States, Australia, and India. Militaries recognize the need to adapt logistics practices toward effective, rather than purely efficient, approaches. These approaches have a similar theme: Effective logistics is predicated on reliable information. In today’s digital world, reliable information often comes from digital technologies that can produce, collect, understand, and even act on data better than humans. And this makes sense from a military perspective, given the increasingly digital nature of many combat capabilities. Better use of information in logistics can allow for optimization, where issues can be predicted or solved more quickly.
As an example, figure 2 below shows that digital tools are improving the combat effectiveness of troops and reducing the need for excess combat capability (the military personnel in traditional combat roles who aren’t being deployed for combat). In other words, digital tools can make combat personnel more effective, potentially reducing the need for more combat troops. So, rather than adding to overhead, investments in digital logistics may be important enablers to help make combat forces effective on an increasingly digital battlefield. This could change the familiar military criticism of ‘tooth-to-tail’ into a positive ‘digital tooth-to-digital tail’.
Information sits at the center of effective logistics, from combat capabilities being increasingly digitally defined to understating cyber vulnerabilities or finding the right global partner. The challenge is how to put reliable information at the center of a redefined military logistics enterprise.
The introduction provides examples that demonstrate how commercial companies are familiar with addressing supply chain and logistics disruptions short of direct military assaults. Indeed, in many instances, the digital capabilities and supply chain resilience practices being developed for businesses can help militaries, too. In fact, militaries are looking at industry to understand how to apply commercial leading practices to military logistics.21
Many of the tools and methods that underwrite the Fourth Industrial Revolution are central to improving commercial supply chain and logistics resilience.22 Commercial advances in digital supply networks are one example. The difference between digital supply networks and linear supply chains is that while linear supply chains are fixed, reactive, and hard to change, digital supply networks are connected to a larger ecosystem, intelligent, and nimble. With digital supply networks, responding to and limiting disruptions can be easier because they leverage more information to make educated physical supply chain and logistics choices, like production or transportation. Indeed, digital supply networks can offer great resilience because they offer the means to limit the duration of disruptions.
At the heart of a digital supply network is data.23 Greater connectivity afforded by a digital supply network comes from integrating existing and new data sets through sensors and visualizations. A digital supply network’s intelligence is, in part, a result of advanced analytics and machine learning to empower proactive operations. Whereas the agility of a digital supply network stems from improved decision-making using AI and optimization algorithms. Improvements afforded by digital supply networks come from tools and practices that allow for better use of data.
For example, an American automobile manufacturer used data sets, predictive models, and visualization tools to assess and mitigate supply chain and logistics risks for tens of billions of parts from thousands of suppliers necessary to produce millions of vehicles a year and protect billions of dollars in revenue.24 More than just diagnosing risk, data can also illuminate alternative sources of supply. Semiconductor production is a good example. Increasing concern over the supply chain concentration of semiconductors has led to calls for greater domestic production. However, market demand doesn’t justify every country producing semiconductors.25 Consequently, it can become important to use data to understand how to reorganize semiconductor production to account for market demand and risks. Ultimately, predictive logistics can help enable more precise and effective military sustainment.
Combining risk assessments with alternative options requires greater global integration and cooperation. That’s because sources of supply are expected to continue to be global, and, as the semiconductor example shows, market forces won’t permit each country to create completely insular supply chains. Global integration necessary to complement digital supply networks can require closer integration of manufacturing, too.
While digital supply networks can create more resilient methods for ensuring supplies get to where they are needed with limited disruption, those items should still be turned into a final product through manufacturing. Industries are leveraging smart manufacturing to integrate methods and protocols to empower how products are designed, manufactured, and serviced.26 Like digital supply networks, data sits at the center of smart manufacturing. Through smart manufacturing, businesses have reported increases in product speed, innovation, reduction in operational costs, faster access to new participants and use cases, and great digital maturity of their organizations.27
In one instance, a European car manufacturer leveraged a cloud-based platform supported by machine learning, Internet of Things, and analytics tools to process production information of the machines, plants, and systems across 122 of its facilities in real-time.28 The use of smart manufacturing technologies allowed the automaker to improve processes, and the platform has since been expanded with plans to connect many more locations and suppliers.29 Because of its benefits, the use of smart manufacturing techniques is on the rise across the commercial sector.30
Maintenance can also be aided by placing data at the center. For example, providing higher-level maintenance, like repairing a ship radar onsite rather than in a country’s shipyard, requires knowing what needs fixing, where the resources are to make repairs, and the means of connecting the two in real-time. It also requires tools, like augmented reality or additive manufacturing, that allow personnel to leverage telemaintenance. Depot facilities connected through data can also mitigate vulnerabilities by helping militaries understand where supplies are and distributing them to minimize the effects of an enemy attack. Advanced manufacturing, which is also predicated on data, can allow militaries to produce more of what they need and when and where they need it.
Smarter logistics practices and tools adopted by the commercial sector can offer some of the solutions militaries require, but not all. After all, military logistics face unique challenges that private logistics don’t. Still, both military and industrial logistics practices should be closely integrated, given the importance of commercial technology and services to militaries. Militaries may need to borrow what they can from the private sector while adjusting certain practices to accommodate what is unique about military logistics.
The military can improve its logistics by taking lessons from commercial practices and collaborating with industry. However, as military logistics has its own distinct characteristics, industry solutions should be customized to meet military needs. To accomplish this, the military should consider:
Steps to build a data-centric logistics enterprise:
For instance, aligning production processes for shared products can mean either partner can help the other produce during times of need without the added costs of installing new manufacturing facilities. Another area where shared incentives could add significant value is reserving industry or defense industrial base capacity, effectively providing militaries with the ability to surge production. Equally, aligning incentives to diversify suppliers, as the companion article, Out with the defense industrial base, in with the defense industrial network discusses, is another area worth considering. Through shared incentives, collaboration can become easier, and so can finding mutually beneficial ways of operating.
Adjusting logistics practices to prevent or win a war requires making important changes across the logistics enterprise. Despite the scale of necessary modifications, progress may not require monolithic solutions. Instead, evolving processes and adopting tools can happen incrementally if they are built around data. Indeed, with data at the center of logistics processes, changes don’t need to be seen as a finish line. Instead, it should be viewed as an evolution. Warfare has changed—it’s time to change how militaries conduct logistics, too.
