Policy Briefing — U.S. DoD AI Ethical Principles
The U.S. Department of Defense formally adopted five ethical principles governing the design, development, and use of artificial intelligence across defense missions.
Executive briefing: On , U.S. Secretary of Defense Mark Esper approved the Department of Defense (DoD) AI Ethical Principles, following recommendations from the Defense Innovation Board. The principles mandate that AI capabilities must be responsible, equitable, traceable, reliable, and governable. They apply to all DoD components and contractors involved in AI development, deployment, and sustainment.

Principle overview
Responsible: DoD personnel must exercise appropriate judgment and care in AI development and use. Equitable: DoD will minimise unintended bias and ensure equitable outcomes. Traceable: AI capabilities must be transparent and auditable, with documentation of methodologies, data sources, and design procedures. Reliable: AI must have explicit, well-defined uses that undergo testing and assurance. Governable: DoD will design systems to detect and avoid unintended consequences, including the ability to disengage or deactivate systems that demonstrate unintended behavior.
The principles align with international norms such as OECD AI principles and NATO’s work on AI adoption. They also complement the DoD AI Strategy (2018) and guidance from the Joint Artificial Intelligence Center (JAIC), now transitioning to the Chief Digital and Artificial Intelligence Office (CDAO).
Implementation guidance
The DoD AI Education Strategy and the JAIC’s Responsible AI Champions pilot provide training and governance frameworks. Components must embed ethical considerations into acquisition processes, using tools like the Responsible AI Toolkit (released later in 2020) and the DoD Responsible AI Guidelines for Projects (RAI Guidelines). Program managers are instructed to identify responsible AI leads, conduct impact assessments, and document risk mitigations throughout the lifecycle.
The DoD is establishing governance bodies, including the DoD AI Executive Steering Group and component-level AI councils, to oversee compliance. Contractors must demonstrate adherence to ethical principles during procurement evaluations. The Defense Acquisition University provides updated curricula on AI ethics, while the DoD Inspector General has authority to review compliance.
Operational and technical implications
Programs must integrate testing, evaluation, verification, and validation (TEVV) processes tailored to AI. The DoD’s Director of Operational Test and Evaluation emphasised the need for mission-focused testing that considers adversarial conditions, dataset shift, and system resilience. Developers should implement model explainability techniques, data versioning, and bias detection tools (e.g., IBM AI Fairness 360, Microsoft Fairlearn). Systems deployed in contested environments must include fallback modes and human-machine teaming concepts that respect human oversight requirements.
Cybersecurity remains critical: AI pipelines must be protected against poisoning, evasion, and model theft. Programs should align with DoD Cloud Computing Security Requirements Guide (SRG) impact levels and FedRAMP authorisations. Supply chain risk management processes under the Cybersecurity Maturity Model Certification (CMMC) and Section 889 prohibitions should encompass AI components and data sources.
Contracting and industry engagement
Contracting officers are expected to incorporate AI ethical obligations into solicitations, evaluation factors, and performance metrics. Requests for Proposals (RFPs) may require bidders to provide responsible AI plans, documentation of bias mitigation, and governance structures. Vendors should prepare to demonstrate compliance with DoD Instruction 5000 series acquisition policies and integrate ethical checkpoints into DevSecOps pipelines.
Industry partnerships such as the Joint Common Foundation and Tradewind initiative encourage responsible AI solutions and testing environments. Contractors should collaborate with the Defense Industrial Base to share best practices, participate in JAIC outreach, and align with the National Defense Authorization Act (NDAA) provisions on AI reporting.
Compliance, oversight, and reporting
DoD components must develop implementation plans, establish metrics, and report progress to the CDAO. Oversight includes inspector general reviews, audits by the Government Accountability Office, and congressional reporting. The principles intersect with existing legal frameworks, including the Law of Armed Conflict, Department of Defense Directive 3000.09 (Autonomy in Weapon Systems), and privacy requirements under the Privacy Act.
Programs must document decisions about AI system deployment, monitoring, and disengagement. Lessons learned should be shared across components to build institutional knowledge. Ethical incident reporting mechanisms are necessary to capture unintended outcomes or harms.
Action plan
- Immediate: Review ongoing AI initiatives for alignment with the five ethical principles. Assign responsible AI leads and integrate ethical checkpoints into program governance.
- 30–60 days: Update acquisition documentation, system engineering plans, and test strategies to include bias mitigation, explainability, and oversight requirements. Engage contractors to confirm responsible AI practices.
- 60–90 days: Deliver training to program managers, engineers, and operators on DoD ethical principles. Conduct gap analyses against TEVV expectations and develop remediation roadmaps.
- Continuous: Monitor updates from the CDAO, JAIC, and Defense Innovation Board. Participate in DoD responsible AI forums, share lessons learned, and adjust governance as policy evolves.
Implementing the DoD AI Ethical Principles embeds trust and accountability in military AI deployments, ensuring mission effectiveness while safeguarding legal and moral obligations.
International coordination and allied alignment
The DoD principles influence allied defense policies. NATO launched its AI strategy in 2021, reflecting similar values of lawfulness, responsibility, explainability, reliability, and bias mitigation. The U.K. Ministry of Defence, Canada’s Department of National Defence, and Australia’s Defence Science and Technology Group have referenced U.S. principles while crafting national frameworks. Contractors operating across allied markets should harmonise compliance documentation to satisfy multiple defence customers.
International human rights bodies, including the OECD and the Global Partnership on AI, monitor defence AI ethics. Transparency about safeguards can help counter narratives that militaries deploy AI irresponsibly. Companies should engage in multilateral fora and public consultations to shape interoperable standards.
Industry readiness and workforce development
Contractors must invest in governance structures, including ethics review boards, model risk management teams, and data stewardship roles. Workforce programmes should cover the NICE framework roles most relevant to AI, complemented by DoD’s Responsible AI training modules. Documentation practices should capture dataset provenance, feature engineering decisions, and explainability reports to withstand audits.
Smaller suppliers may require support to meet DoD expectations. Partnerships with primes, academia, and federally funded research and development centres (FFRDCs) can provide access to testing environments and governance expertise. Companies should evaluate insurance coverage, liability clauses, and export controls (ITAR/EAR) when delivering AI-enabled systems.
Metrics and continuous improvement
Programs should define key performance indicators (KPIs) to measure responsible AI adoption: percentage of projects with completed ethical assessments, bias testing frequency, incident reports addressed, and time to deploy corrective actions. Continuous monitoring is essential; telemetry from deployed systems should feed back into model retraining pipelines with safeguards against data drift.
The DoD encourages iterative learning through pilot projects and after-action reviews. Organisations should maintain lessons-learned repositories, integrate findings into acquisition guidance, and adjust engineering standards accordingly. External oversight, including congressional interest and civil society scrutiny, underscores the need for transparency and responsiveness.
Follow-up: The Department of Defense issued its Responsible AI Strategy and Implementation Pathway in 2022, stood up the Chief Digital and Artificial Intelligence Office, and updated Directive 3000.09 on autonomy in weapon systems in January 2023 to embed the principles in acquisition and operations.
