  • The assessment found that the program has a clear and unique purpose and is well-managed in its efforts to adapt to evolving threats.
  • The program has demonstrated good progress in achieving its long-term and annual goals, including improving its capability/capacity to meet an increasing percentage of customer's annual transport needs. In fiscal year 2007, the program completed 113 convoys vs. only 60 in fiscal year 2002.
  • Funds were spent for their intended purpose but the unique nature of the program results in it carrying over its appropriations into the next fiscal year.
