A contact of mine who is associated with a company that has been selected to support the JSF if it does enter service with the ADF said that this aircraft is going to be the best value for money platform available at the right time to replace the F111/F18. It is being built using the best components that provide significant operational capability at the best price over the life of the aircraft type ie the aircraft is being built to a price so there shouldn't be any nasty surprises for the government after contracts have been signed.
