About Mantle – www.mantleresilience.com

Mantle exists to build and connect the critical sovereign capabilities the UK's security and resilience require. The UK remains dependent on supply chains it does not control and on industrial capacity it cannot always scale at pace. The Company's work is to shorten those chains, to put manufacturing and systems integration onshore, and to give the resulting businesses a credible route into defence, national security and other strategically important markets.

The strategy aligns with the Strategic Defence Review 2025 and supports the UK Government's Critical Minerals Strategy (Vision 2035), including its objectives for greater domestic production and recycling and reduced reliance on single-country supply.
