Although the reform initiative will help, Kendall said the key to maintaining the U.S. military's dominance was spending more money on research and development and attracting talented workers to oversee weapons programs.
"But at the end of the day, the fundamental driver on how fast we can modernize is how much money we spend and on the quality of the people out there doing the work . . .," he said.
And if the government failed to adequately fund research and development, "you will not have a future weapons system."
Potential automatic budget cuts, which Congress has imposed on the entire federal budget, could severely undermine vital research and the time lost carried its own cost, Kendall said.
In the meantime, adversaries were investing in new weapons.
"Time is not recoverable. And if I don't do research, I have to do it later and take the time to do it," he said.
