Well, I’d start with there Ron is that, we’re got and our experiencing significant growth in our classified portfolio already. It’s a bright spot for the company. I think recently, we’ve been when we aggregate all of our classified programs together sort of a 7% growth rate. So it is a place where because of Skunk Works, our space operations, some segments of RMS and MSC even where we have significant talent and capability to work in those kinds of really advanced spaces. I’d basically said in the prepared remarks, there are areas of this company where we are endeavoring to move into areas beyond known science to address what our customers kind of challenges are that they are facing. And so we have the capability to take advantage of a larger classified program growth rate on the part of government spending if that’s what happens. So we’re in good shape to do that. There are missions that you need to differentiate though when it comes to aircraft, right. There’s the reconnaissance and surveillance mission, right, which can a lot of it can be done with unmanned system. And that’s one of the strengths of Skunk Works for example. So that mission we have a real strength in unmanned surveillance ISR systems are called. Then you’ve got the air superiority type of aircraft, right? So you can think about F-15, for example, F-22. NGAD is the next generation air dominance aircraft that is classified. It’s the Air Force recently said that there is competition. Now beginning for that are in train for that air dominance aircraft that it was very old aircraft. And then there’s the kind of all-purpose strike aircraft, right, so that's F-16, F-35. Those kind of airplanes, again, where we have the advantage in F-35 is volume, right. We’ve got the committed volume for the strike mission. And basically all three variants, right, so it’s Air Force, which is a land base, long runway solution, it’s for the Marines, which is the B model, which is a land base, short runway, so a solution [Indiscernible] take-off and landing or carrier take-off or landing solution. And then you’ve got the C-model, which is the pure Navy, big carrier, tail hook type of landing aircraft. So the capacity for the strike mission, can and will be pursued through the F-35 and large part for the near future. So those are the ways to think about aircraft. So the classified programs are going to be largely in air superiority and ISR for the most part, and then there’s the bomber mission, which is largely going to be carried out by the B-21 Going forward. So hopefully, that’s a bit helpful to your question there.
