It appears that the $Billions that Australia has given the US is not enough to lift US submarine construction out of the doldrums and they need another injection from Congress. I believe that the shipbuilders are having to offer significantly higher wages to attract workers and this is blowing out the budgets.
They have a lot of work to do to free up 3 Virginia’s for the RAN to acquire.
