Should the F-35 show up tomorrow, it would have the same capabilities as our F-18s have had for 28 years of their service life in the Arctic. We will have beyond line-of-sight communication on the F-35 by the time we reach our operating capabilities in 2020. The modifications for beyond line-of-sight will be integrated in the aircraft in what's called the block III series, which is beyond 2018 and 2019, and it will be retrofitted to all the other aircraft that have been produced beforehand.
We did 50 years in NORAD without having beyond line-of-sight communications. As I said, our F-18s have only had it for two years. So we know how to do the business. Beyond line-of-sight adds an additional flexibility factor that is certainly welcome, and it certainly would be part of our future fleets but I have no concern as to the F-35's ability to deliver NORAD mission tomorrow, should it have to.
