The World’s Largest Air Forces By Budget

What are the largest air forces in the world by budget? Short answer: no one really knows. No matter the criteria used, it is clear that the United States Air Force has the world’s largest such budget, but beyond that, it gets murky. Many countries, like the UK, China, and Russia, do not provide breakdowns in their military budgets for how much is spent specifically on the air force. Other big issues include converting currencies, and the different expenses are included or excluded between air force budgets. For example, the US Air Force budget includes nuclear expenses.
