I'll start, and my colleague Rear-Admiral Waddell may wish to add.
There's interaction at numerous levels, regularly, just through relationships and the sharing of information that comes to our attention or to their attention that is relevant. We also talk a lot about innovation. We want to make sure we're collaborating and not duplicating. You will see collaboration among the researchers but also among air forces, navies, etc., to advance the cause there.
Admiral Waddell.
