And if you look at the contract of Australia in 2006, they must pay around 780 million US dollar and additional fee for sustainment program about 80,7 million US dollar for 4 unit C 17 Globe master. And the deal was done in 2006, in which inflation rate and time of delivery will be put into consideration for new price tag.
I had a calculation about price tag per unit, training session, simulator, spares and maintenance equipment in which USA like their partner to put all of it into contract for all of their arms sales will be going around 450 millions US dollar to 550 millions US dollar for a unit of C 17 Globemaster in 2013. The cost purchasing per unit will decrease if you purchasing more units from USA and this was the standard pattern when you do a business with them.
