The UK Ministry of Defence (MOD) has developed five core AI Ethics Principles to guide the responsible use of Artificial Intelligence in defence. These principles—Human-Centricity, Responsibility, Understanding, Bias and Harm Mitigation, and Reliability—aim to ensure that AI systems align with democratic norms, societal values, and human rights. They serve as your guide for creating systems that are both operationally effective and ethically sound. These principles are applicable across the full spectrum of use cases for AI in Defence, from battlespace to back office, and across the entire lifecycle of these systems. By embedding these principles into defence operations, the MOD ensures ethical oversight while leveraging AI’s capabilities to enhance operational success. These principles are designed to ensure that AI technologies are developed and deployed in a manner that aligns with the MOD's core values of responsibility, transparency, and accountability.

Why do the AI Ethics Principles matter?
How do the AI Ethics Principles shape our work in Defence?
- Human Centricity: Assess and consider the impact of AI-enabled systems on humans throughout their entire lifecycle, ensuring both positive and negative effects are evaluated. See What does Human Centricity mean in the context of AI development for UK Defence?
- Responsibility: Clearly establish human responsibility for AI-enabled systems, ensuring accountability for their outcomes, with defined mechanisms for human control throughout their lifecycles. See What does Responsibility mean in the context of AI development for UK Defence?
- Understanding: Ensure that AI-enabled systems and their outputs are appropriately understood by relevant individuals, incorporating mechanisms to facilitate this understanding into system design. See What does Understanding mean in the context of AI development for UK Defence?
- Bias and Harm Mitigation: Proactively mitigate risks of unexpected or unintended biases or harms resulting from AI-enabled systems, both during initial deployment and as they learn, change, or are redeployed. See What does Bias and Harm Mitigation mean in the context of AI development for UK Defence?
- Reliability: Demonstrate that AI-enabled systems are safe, reliable, robust, and secure, with regular monitoring, auditing, and evaluation to maintain these qualities. See What does Reliability mean in the context of AI development for UK Defence?
1. Human-Centricity - AI must be designed and deployed with humans at the centre, ensuring human oversight and accountability.
- Courage: Supports the principle of making morally courageous decisions by ensuring humans remain accountable for AI actions, especially in high-stakes situations.
- Respect for others: Places human dignity and rights at the forefront of AI applications, aligning with treating individuals with respect and ensuring systems do not undermine this.
2. Responsibility - Clear accountability must be maintained for AI use, ensuring systems are used ethically and that individuals are responsible for their deployment and outcomes.
- Integrity: Reinforces personal responsibility and honesty in the deployment of AI technologies, ensuring ethical conduct is maintained.
- Discipline: Promotes the orderly and lawful implementation of AI, reflecting the MOD's commitment to adhering to rules and principles.
3. Understanding - AI systems must be transparent and explainable, allowing operators and decision-makers to understand how they work and make decisions.
- Excellence: Aligns with striving for clarity and understanding in the use of advanced technologies, ensuring personnel are well-informed and skilled in their use.
- Integrity: Ensures honest and transparent communication about system capabilities and limitations.
4. Bias Mitigation - AI systems must be designed and deployed to minimize bias and prevent unintended harm.
- Respect for Others: Reflects the commitment to fairness and equality, ensuring AI systems do not perpetuate or amplify biases.
- Integrity: Reinforces the ethical obligation to identify and mitigate biases, maintaining trust in AI-driven decisions.
5. Reliability - AI systems must be dependable and perform as intended in all circumstances, with robust testing and validation to ensure safety and accuracy.
- Discipline: Encourages adherence to rigorous protocols and standards, ensuring AI systems operate reliably and predictably.
- Courage and Excellence: Ensures AI supports decision-making with high reliability, enabling personnel to act with confidence in critical situations.
Why do the AI Ethics Principles matter?
When developing AI for defence, the ethical and operational implications of your work cannot be ignored. The MOD AI Ethics Principles are deeply rooted in the MOD Core Values, reflecting a shared commitment to ethical behaviour, accountability, and operational excellence. These principles ensure that the adoption of AI in defence aligns with the moral and ethical framework expected of MOD personnel, safeguarding both operational integrity and public trust. They can:
- Prevent misuse and reduce risks: Through careful design, you minimise risks of bias, misuse, or harm, ensuring systems behave predictably and responsibly in real-world scenarios.
- Safeguard human rights and values: As a developer, you ensure your systems protect human welfare by embedding safeguards that prioritise ethical outcomes and operate within democratic and legal frameworks.
- Enhance operational effectiveness: By focusing on reliability, explainability, and usability, your systems improve decision-making and operational success on the battlefield or in strategic contexts.
- Ensuring long-term viability: Ethical systems are more likely to remain legally compliant, operationally relevant, and publicly accepted, providing lasting value to defence capabilities.
- Build public and international trust: The transparency and accountability built into your systems strengthen confidence among users, the public, and international partners, making your work a trusted component of defence operations.
How do the AI Ethics Principles shape our work in Defence?
The AI Ethics Principles are here to guide and help individuals working in the defence sector to ensure that they are developing the best tech possible. They are here to:
- Guide developers through complex ethical dilemmas: The principles serve as a compass for navigating challenging ethical decisions, helping you resolve conflicts between innovation, operational needs, and moral responsibilities.
- Build systems that fully meet MOD standards: Use the principles to ensure your systems comply with MOD procurement criteria, ethical guidelines, and project management requirements from the outset, setting a solid foundation for success.
- Promote accountability through transparent processes: Document and openly share your methodologies, audit findings, and ethical considerations, reinforcing trust, collaboration, and accountability throughout the system's lifecycle.
- Foster collaborative development across disciplines: Partner with legal, ethical, and operational experts to create systems that adhere to robust, practical, and enforceable standards, ensuring multi-stakeholder alignment.
- Embed continuous improvement through feedback loops: Design your systems with built-in mechanisms for ongoing evaluation and enhancement, driven by real-world data and user feedback.
Taken together, these principles ensure that your AI systems are built to serve their intended purpose effectively while upholding moral and legal standards. As an AI developer for defence, your work goes beyond just coding and algorithms, it directly impacts the ethical and operational effectiveness of MOD initiatives.
Rather than being a barrier to innovation, considering ethics at the right stage of your development process can help to make your product more useful for the end customer. Being able to demonstrate that you have proactively anticipated and addressed such challenges would definitely be a “selling point”, but more importantly, is a necessary part of the management of ethical risk which you will need to engage with before your product can be considered viable for UK Defence.
Numerous countries besides the UK have developed and published ethical AI policies to guide the responsible development and deployment of artificial intelligence. These policies often align with international frameworks, such as the OECD
AI Principles, which emphasize inclusive growth, human-centred values, transparency, robustness, and accountability. It is easy to see the way that the UK principles align with such concerns, even if they may be articulated in a slightly different way. This demonstrates that it is possible to arrive at a similar place using different reasoning or processes. See
