Networked Warfare

Military Doctrine: From Network-Centric Warfare to Joint All-Domain Operations

Origins of Network-Centric Thinking

The concept of network-centric warfare emerged formally in 1998, when Vice Admiral Arthur K. Cebrowski and John Garstka articulated the idea that networking sensors, commanders, and shooters could compress decision cycles and amplify combat power. The foundational tenets were straightforward: robustly networked forces improve information sharing, better information sharing enhances shared situational awareness, and shared situational awareness enables self-synchronization among distributed units. These principles drew from the broader Revolution in Military Affairs of the 1990s, which recognized that information technology was transforming not just civilian economies but the character of warfare itself.

The United States Navy's Cooperative Engagement Capability became one of the earliest operational implementations, allowing warships to share radar tracks and coordinate air defense across an entire carrier strike group. The Army followed with its own Force XXI experiments and later the Brigade Combat Team Network, while the Air Force invested in the Joint Tactical Radio System to create software-defined communications that could bridge incompatible legacy radios. Each service pursued network-centric capabilities through its own lens, a pattern that would create significant interoperability challenges in the decades ahead.

Combined Joint All-Domain Command and Control

By the late 2010s, the Department of Defense recognized that service-specific networking programs were insufficient for the multi-domain battlespace envisioned by the 2018 National Defense Strategy. The result was Combined Joint All-Domain Command and Control, or CJADC2, a concept intended to connect sensors and decision-makers across all military branches and allied partners into a unified information architecture. Each service contributes a component program: the Air Force developed the Advanced Battle Management System, the Army stood up Project Convergence, the Navy launched Project Overmatch, and the Space Force is building the National Defense Space Architecture through the Space Development Agency.

The scale of this undertaking is substantial. The Joint Warfighting Cloud Capability, awarded in late 2022 to Google, Amazon, Microsoft, and Oracle for approximately $9 billion, provides the cloud infrastructure layer. The Army's Integrated Tactical Network Capability Set 25 is intended to deliver JADC2-ready networking at the brigade level. A 2025 Government Accountability Office report found, however, that six years into the initiative, the military services were still pursuing projects largely in isolation and without a comprehensive framework to guide investments or measure progress. The GAO recommended that the Department of Defense develop clear metrics and establish organizational accountability to prevent the effort from stalling.

Multi-Domain Task Forces and Operational Implementation

On the ground, the Army's Multi-Domain Task Forces represent the organizational expression of networked warfare thinking. First established in 2019, these units integrate air defense, long-range precision fires, cyber and electronic warfare, space, and intelligence capabilities within a single formation designed to operate across all domains simultaneously. The concept reflects a shift from the sequential, domain-specific operations of earlier decades toward simultaneous, networked effects that can overwhelm an adversary's ability to respond.

NATO allies are pursuing parallel efforts. The Alliance's concept development community convenes annually to align multi-domain operations frameworks across member states, with the 2024 conference in Vilnius bringing together 230 experts from 27 member and five partner nations. European defense planners have emphasized that network-centric approaches should exploit the technological advantages of free societies rather than replicate the attritional, lower-technology warfare observed in the Ukraine conflict. The challenge lies in creating interoperable networks that function seamlessly across national boundaries, classification levels, and vastly different legacy equipment.

Cyber Operations: Networked Warfare in the Digital Domain

The Convergence of Cyber and Kinetic Warfare

Modern military doctrine increasingly treats cyberspace not as a supporting function but as an integral component of combat power. The U.S. Army's updated field manuals condition commanders to think of information as part of, rather than merely supporting, the total means of destructive and disruptive force available to a formation. This doctrinal shift reflects hard lessons from the Ukraine-Russia conflict, where both belligerents have employed cyber capabilities alongside kinetic strikes to degrade command networks, disrupt logistics, and shape the information environment.

U.S. Cyber Command, established in 2009 following the Buckshot Yankee breach of classified military networks, has grown into a unified combatant command with an estimated annual budget approaching $17 billion when accounting for all cyber-related activities across the services. The 2025 edition of The Cyber Defense Review highlights an ongoing debate about whether the United States should establish a dedicated Cyber Force as a sixth military branch, mirroring the creation of the Space Force in 2019. Proponents argue that the current model -- where each service generates its own cyber capabilities -- creates duplication and inconsistency. A congressionally mandated National Academies study found that the status quo is increasingly inadequate for the scale and complexity of cyber threats facing the nation.

Enterprise Cyber Defense as Networked Warfare

Outside the military context, the language of networked warfare has permeated enterprise cybersecurity. Organizations deploying zero-trust architectures, security information and event management platforms, and extended detection and response systems are engaged in a form of networked defense where sensors distributed across endpoints, cloud workloads, and network segments feed into centralized analysis engines that correlate threats in real time. The Defense Information Systems Agency is working toward full zero-trust implementation across the Department of Defense by 2027, an effort that has implications for how the entire federal government approaches network security.

The threat landscape reinforces the urgency. CrowdStrike's 2024 threat report documented a 60 percent increase in interactive intrusion campaigns by adversaries globally, with North America experiencing the sharpest rise. Nation-state actors, particularly those attributed to the People's Republic of China under campaigns designated Volt Typhoon, have demonstrated the ability to pre-position access within critical infrastructure networks for potential disruption during a geopolitical crisis. Former NSA and Cyber Command leader General Paul Nakasone warned publicly in early 2025 that the United States is falling increasingly behind its adversaries in cyberspace, citing the nation's inability to adequately secure its own networks against persistent, sophisticated intrusions.

Cognitive Warfare and Information Operations

An emerging dimension of networked warfare extends beyond technical networks into the cognitive domain. China's People's Liberation Army has evolved its doctrine from psychological warfare to what it terms Cognitive Domain Operations, combining cyber capabilities with influence operations to shape adversary behavior and decision-making. The U.S. intelligence community's 2024 threat assessment noted the PLA's growing interest in using generative AI to produce synthetic media, including deepfakes, as instruments of cognitive warfare. NATO has begun developing frameworks for Cognitive Domain Operations within existing joint doctrine, though researchers caution that the terminological landscape remains crowded with overlapping concepts including information warfare, influence operations, and hybrid warfare.

Critical Infrastructure: The Industrial Dimension of Networked Conflict

SCADA Systems and the Expanding Attack Surface

Supervisory Control and Data Acquisition systems have managed large-scale industrial processes for over fifty years, providing the networked backbone for energy grids, water treatment plants, manufacturing facilities, and transportation networks. The global SCADA market was valued at approximately $39 billion in 2023 and is projected to reach $66 billion by 2030, reflecting both the essential nature of these systems and the growing investment in modernizing them. Historically, SCADA environments operated in isolation with minimal external connectivity. The integration of Internet of Things devices and cloud-based analytics has brought significant operational benefits -- including predictive maintenance, remote monitoring, and real-time optimization -- but has simultaneously introduced cybersecurity vulnerabilities that transform industrial infrastructure into potential targets of networked warfare.

The Cybersecurity and Infrastructure Security Agency maintains that legacy industrial control systems represent one of the most challenging areas of national cyber defense. Many facilities still run outdated operating systems and communication protocols that lack encryption or authentication mechanisms. The brownfield challenge -- layering modern IoT devices and cloud connectivity onto decades-old industrial infrastructure -- creates complex hybrid environments where a vulnerability in a single sensor or programmable logic controller can provide a pathway into systems that manage physical processes with life-safety implications.

State-Sponsored Threats to Networked Infrastructure

The weaponization of access to industrial networks represents a strategic dimension of networked warfare that extends well beyond traditional military targeting. The Stuxnet operation, which damaged Iranian uranium enrichment centrifuges through malicious code injected into Siemens industrial controllers, demonstrated that cyber capabilities could achieve physical destruction of networked industrial systems. Since that 2010 disclosure, the number of publicly reported vulnerabilities in industrial control systems has expanded dramatically, with more than 400 ICS-specific vulnerabilities disclosed in a single recent year, over 100 of which were zero-day flaws with no available patch at the time of discovery.

The convergence of operational technology and information technology has made network segmentation a foundational defense principle. CISA recommends separating ICS networks from corporate environments using physical or virtual segmentation, implementing continuous monitoring and anomaly detection, and maintaining comprehensive asset inventories that track every device across SCADA architectures. The agency's Controls Environment Laboratory Resource at Idaho National Laboratories allows government and industry partners to simulate kinetic cyber-physical attacks, providing hands-on experience with the cascading effects that compromised industrial networks can produce across interconnected systems.

Resilience as a Strategic Imperative

The recognition that networked warfare encompasses attacks on civilian infrastructure has driven a broader rethinking of national resilience. The 2023 Department of Defense Strategy for Operations in the Information Environment situates infrastructure defense within the context of integrated deterrence, acknowledging that adversaries may target energy grids, water systems, and communications networks below the threshold of armed conflict. The Department of Energy, the Environmental Protection Agency, and sector-specific agencies are each developing cybersecurity requirements tailored to the industrial control systems under their regulatory purview. The challenge is coordination: networked warfare against infrastructure crosses bureaucratic boundaries just as it crosses the boundaries between physical and digital domains.
