I will just comment briefly, Mr. Chair.
The public announcement is formally announcing that we're beginning to define solutions. The first public announcement is never the contract award or the beginning of spending money. It is we will formally be able to go and talk to companies, send out price and availability requests, letters of interest requests, and have a formal exchange.
For a multi-billion-dollar program it normally is at least a couple of years prior to effective project approval and a contract award. The actual contract award is tied to the cash phasing in the investment plan, which is all phased. For example, the F-18 is phased 2016-17. It's not phased sooner because I don't need a new fighter aircraft before 2016-17.
