This mod adds a giant multifunctional aircraft carrier (for planes, helicopters, and much more), 4 times larger and bigger than the original aircraft carrier of SF.
This one is situated in the bay of San Fierro, and you can use it to land with larger airplanes.
It is enterable with many rooms and a large amount of objects used and available. This is not only an aircraft carrier : it also serves as container ship, cruise ship and more.
There's some surprises inside, but you can watch a video to have a "survey" of the aircraft-heli carrier : https://www.youtube.com/edit?o=U&video_id=-JVueFRg3pU
