 So it's an FNA, which means it's both a fighter and an attack aircraft. So it does air-to-air missions, and it also can attack targets on the surface, whether it's a hostile fleet or whether it's forces on land. So, again, it's been sort of the standard platform for quite some time. It's starting to give way to stealth aircraft. The F-35C is a stealth platform. It looks like we'll have sort of a hybrid fleet.
