Defence is organised, resourced and managed on a UK basis to provide high levels of protection and security for all parts of the UK and its citizens at home and abroad. Decisions on spending are based on meeting defence requirements and ensuring value for money. As part of the UK, Scotland benefits from billions of pounds of MOD contracts placed directly and indirectly with hundreds of companies, which sustain thousands of skilled jobs. The Treasury does not produce estimates of defence expenditure in the nations and regions or assessments of its economic impact.
