The US Air Force has warned the Bush Administration that a decade of defense cuts has left it with an aging fleet of aircraft that must be replaced. The Air Force wants an extra 20ドル billion per year (or more) in order to cover its current shortfall (7ドル billion by next year) and buy 150+ new aircraft every year for the next decade. And they have warned the incoming administration that any missile defense program must come from new funding, not be taken out of existing budgets. The Air Force wants to move toward new methods of warfare, finding ways to attack an enemy beyond a show of force but short of bombing targets. Possibilities include information warfare, non-lethal attacks (e.g., shutting down power generators for a few days by bombing the site with non-lethal materials that cause short circuits), and directed energy weapons which might disable some sensors or destroy offensive missiles before they can launch.-Stephen V Cole
