It depends on the state, and which one you're buying, and how much lead time you have. I mean, typically we can have a process such that the contract can be signed within a matter of a couple of years from the time, or probably less than that, once the military requirements are met.
So it's a question of the state of those jets. Are they operational jets today? Because if that's the case, maybe we can get them sooner. If they're in the developmental stage, we'll have to wait a few more years.
