How much, roughly, do we buy from Russia? I know we buy more from Russia than just these engines.

The idea that we can be challenged in terms of technological superiority is something that people don't take very seriously initially.

With threats around the world ranging from ISIL and rogue nations on one end, to increasingly assertive near-peer competitors on the other, it is an important time to focus on innovation and investments in our advanced capabilities.

We found out in 1945 that the Germans were, overall, much farther advanced than we were, dealing with missiles and so forth.

We want to get through it, but we don't want to jeopardize anything for American security to do that.

We all want to get rid of the dependence to some extent on the Russian engine. I think that is a given.

What's going on with sue and settle is a violation of State rights and, I think, private property rights.

We can't defend this Nation with yesterday's weapons when you have potential competitors or adversaries moving to the next level.

Shouldn't you have let the committee decide whether or not they wanted to have information about everyone? I mean, everyone is everyone.

I doubt seriously that Judge Williams or Pollak or Scalia would have had the patience that this committee has had in this process.

You've been delaying.

Do you agree with this assessment?

Are there program gaps in ballistic missile defense? Are there gaps you have not yet focused on?

Please detail any exercises, table top exercises, or war games you have participated in concerning left-of-launch ballistic missile defeat.

What is left-of-launch capability? In other words, you're talking about destroying ballistic missiles on the ground before they're launched at us?

Please identify and summarize the studies MDA has conducted or participated in evaluating missile defense options and limitations against boost-glide systems and maneuvering systems.

How much longer would it take and how much more would it cost to develop, test and field Poland Aegis Ashore site on the planned timeline in the normal 5000 series rules and regulations? Would MDA be able to meet the President's 2018 goal?

Am I correct that under the current plan for the ground-based midcourse defense system, there are no operational spares GBIs for, is it 5 or 6 years?
