Thank you, Mr. Chair.
Welcome to all our witnesses today. I thank you for your testimony.
I'm going to start with Mr. Perry.
Acknowledging that your opening remarks were focused on procurement, I'd like to focus on another aspect, which is investment. That's an area you've also been vocal on, specifically on NORAD and NORAD modernization. I'm hoping that you're comfortable answering some questions on that front.
Acknowledging that NORAD is a system of systems, and the fact that for its modernization there are two schools of thought or multiple venues for modernization, would you be comfortable making comments about these venues? Which one would you recommend?
