Probable Real World Program Costs of the “Poisoned Chalice”
• Funding the Afghan War, Iraq War, and GWOT in the outyears would require supplementals ranging from 5-15%.
• The real world cost of the expansion of military and civilian manpower, and sustaining the all-volunteer force structure will be at least 5-8%higher than DoD estimates.
• Future procurement costs are badly underestimated, as are the cost of reset and modernization due to program delays, cutbacks and possible cancellations.
• Program delays, cutbacks, and cancellations may limit cost growth to 10% over the DoD procurement and RDT&E estimate, but no prediction is really possible.
• O&M will probably be 5-8% higher that DoD estimates if war continues to create a major burden on O&M.
• These factors will create turmoil and instability in the National Security planning, programming, and budgeting process through the life of the coming administration.
