 We're very very proud to be here with two of the F-15EX is the only two in the world right now Now it's Air Force Base offers the best air-to-air and surface-to-air training range that we currently have to offer So what we're doing is we're building on that primary objective is to evaluate the the air-to-air superiority of the F-15EX platform to meet the initial goal for the platform in the F-15C model replacement So kind of the big thing. We're trying to take away is really showing the the differences between the EX and the C model And when we're looking at a replacement aircraft, you're not only looking at just new long-drawns on the airplane But you're also looking at new capabilities and then really not necessarily new but improved capabilities More situations that we can put this airplane in the better information We learn because they're all just slightly different and then integration is for the key thing in the Air Force to be able to get multiple different kinds of fighters to work together to be a more formidable force and getting the situations is the best way to test that
