I am very concerned, about this possible window, that we don't have heavy-lift capability. I just am.

I think it is in our Nation's interest.

If the 1608 language was fixed so that we could use those additional 14 RD-180 engines, would it remedy the situation that you just all said was unacceptable?

Is that optimistic or is it practically realistic?

Is that an acceptable national security risk, in your opinion?

I just want you to understand--and I am not picking on you, because, Blue Origin has got all kind of optimistic promises out there, as does Aerojet.

Ms. Shotwell, you were recently quoted in the media stating that SpaceX is working on a higher-thrust engine.

What are the risks of this approach?

I love it when billionaires want to spend their own money to do cool things that help the country, but it's still a business.

Before I stop, I want to go to what Ms. McFarland just described as this potential gap of time when we won't have access, particularly on the heavy-lift...

Do you agree that there is the potential, as outlined by Ms. McFarland, that there could be a multi-year period where we would not have assured access to space for the heavy NRO platforms?

Do you plan to fund an entirely new launch vehicle and all new infrastructure? Do you know what it will, or could, cost the taxpayer?
