Director Warhead Capability Strategy

​Sustaining the UK's nuclear deterrent is the Ministry of Defence's highest priority, and the Director Warhead Capability Strategy plays a pivotal leadership role in ensuring the long-term resilience, coherence and effectiveness of the warhead enterprise that underpins that mission.​ As one of three Directors within the Warhead Group (WHG), and a member of the Defence Nuclear Organisation (DNO) Senior Leadership Team, you will work closely with the Director General Warhead and Chief of Defence Nuclear to shape the future of the UK's warhead capability. The role was established following the transformation of the warhead operating model and the return of Atomic Weapons Establishment (AWE) to government ownership, with a particular focus on strengthening strategic coherence, enterprise integration and informed decision-making across the Defence Nuclear Enterprise (DNE).​

You will be leading the Capability Strategy Directorate, which provides the strategic centre of gravity for Warhead Group, ensuring a clear “golden thread” from policy and capability requirements through to portfolio decisions, investment priorities and delivery outcomes. The Directorate is responsible for developing the strategies, capabilities, user requirements, technologies and strategic options to sustain and evolve the UK's warhead stockpile and Nuclear Threat Reduction (NTR) capabilities, ensuring they remain aligned to Government policy, Defence priorities and future national security requirements.​
