Junglie,
Fortunately in this regard, air defence is aguably not the main JSF acquisition driver; the balance is on the side of Strike. Hopefully, after the period you suggest, we will be sufficiently far down the investment road that cancellation would be v.difficult. That is not to say that the project will not be prone to 'kin bean-counters messing about with total numbers, support, weapons, kit upgrades etc. etc.
Navaleye,
Thanks for the phots - suggest you keep one or two in your back pocket for future caption competitions!!
