Over a 6-year period, US defense expenditures are set to increase by over 1.5 times, rising from $162 billion to $278 billion. The aviation sector, the largest category, sees a minor increase from $57 billion to $68 billion. However, other categories witness substantial changes: expenses for the navy nearly double, reaching a level close to aviation, missile defense systems experience a fourfold increase, and spending on space systems triples. Command/communication/intelligence systems see a bit more than a twofold rise, while missile system development funding maintains an average growth rate. Conversely, ground systems face a decrease in funding, indicating a decline in popularity.
