An internal investigation by the publisher of the International Journal of Intelligent Unmanned Systems into a series of submissions uncovered evidence that the peer review process had been compromised across multiple articles. As a result of these concerns, the findings of those articles cannot be relied upon. As trust in the content is central to the integrity of the publication process, the editor and publisher have taken the decision to retract all of the articles listed below; these notices are being published as a group within this online-only supplement. This decision has been taken in accordance with Emerald's publishing ethics and the COPE guidelines on retractions. The journal is committed to identifying and addressing research concerns, fraud, misconduct and unethical activity and will continue to correct the scientific record with transparency, ensuring that readers are alerted to concerns and can rely on its published output. The publisher of the journal sincerely pledges to maintain and strengthen its commitment to research integrity so that authors and readers can continue to have confidence in the quality of the published material.
