Thank you very much, Mr. Robertson.
Before we go to the next questioner, the chair has asked two previous witnesses a very similar question. It has to do with an issue that was brought up by Mr. Robertson around the angst concerning procurement.
As a nation we are about to replace a very expensive piece of equipment called the F-18. I think you are familiar with that so I won't go into it. We have a choice. We can purchase aircraft other than the current consortium that we belong to, the F-35, and we'll get some regional benefits on each of the purchased aircraft. However, we could go to the F-35 and have an opportunity to have some economic advantage by every single aircraft that is produced, I believe it's in the hundreds. One of the other advantages is the ability of interoperability because that consortium composes many of our NATO allies.
I would appreciate it if you would both get back to the committee in writing on that question because I do not want to usurp much more time from the members.
Mr. Opitz, for five minutes.
