We introduce our software capability in what we call blocks. In 2014, the United States Marine Corps will go to operational capability with what we call a block II airplane. That block II airplane is fully capable of going into combat and is an operationally acceptable airplane for any air force, navy, or marine corps that wants to fly it.
At that point in time, the next block of software will be in flight tests. As soon as it completes flight tests, the software is dropped back to the other airplane, which instantly becomes a block III aircraft. There are no hardware changes: there's no mod and no retrofit associated with that. Canada's airplanes come in 2016. We will be completing flight tests in early 2016, and your airplanes will either have that software capability in them or they'll get it very shortly after they get here.
By the way, the reason the Marine Corps is taking that airplane to IOC is that it's so much better than the airplanes they're operating today.
