good question...
wiki shows a picture of it. it looks like an old-timey aircraft carrier...they are calling it a light aircraft carrier...

Ah, yes. When it is not covered with smoke it is obvious. I thought maybe it might be more of a helicopter assault base. Makes sense. I didn't think to look at Wiki - always a good quick source despite some shortcomings. Thanks.
