There is a 'default ' carrier located just off Hawaii that you can land on.
Go to PHOG (Kahului - Hawaii), line up on runway 20 & fly on a heading of 194 degrees for 32nm.
In front of you, you will see a small island & there is a fleet of about 6 or 7 ships sitting just behind it.
Once you have landed on the carrier, you can use some of the 'ramps' to go down to the next deck & refuel.

Hope this is of some help to you.
Have fun.........................
