 Defence Nuclear Organisation

The Defence Nuclear Organisation (DNO) is typically a body that falls under the purview of a country's defense ministry or similar government department, responsible for overseeing nuclear weapons programs, nuclear policy, and related research and development. In the context of the United Kingdom, for example, the DNO is associated with the Ministry of Defence (MoD) and plays a critical role in managing the UK's nuclear deterrent capabilities, including the Trident missile system.
