Mr. Chair, that's absolutely correct.
The challenge we have is that while our roles will continue in both air-to-air and air-to-ground, the adversary and the capabilities of the adversary continue to evolve. What we need to do is put ourselves in a situation where we can evolve our capability to stay ahead of the adversary, and what we have determined is that only the F-35 gives us that opportunity to stay ahead, such that our men and women who fly these aircraft will survive the mission, perform the mission exactly correctly, and be able to conduct another mission the next day.
