This package, aicarriers2.zip, uses the same carriers that FSX Acceleration uses. It allows you to place them ( or a fleet ) where ever you like. Note the cruisers and destroyers have hard decks, which I believe means you can land a helo on them!

Another package by the same author, aicarriers1.zip, allows placement of the FSX carriers in 20 different locations with their routes shown via an included Google Earth KML file.

And on the authors ( lco277 ) web site ( http://lc0277.nerim.net ) you can find his "AI Boat Utility" that lets you create your own moving fleets anywhere you wish and define their sailing routes with Google Earth.

Very nice!
