I'm interested in the aviation capabilities of the Amphibs and not so much interested in the warfare capabilities of the destroyers and cruisers. I went to the Navy site and looked through each type of ship. The amphibs are what caught my attention. I also spent a week on an amphib in high school, which I know is not a full picture of what working on what would be like, but I enjoyed it.
If all you're interested in is aviation, I would try to get a CVN. I'd say their aviation capabilities put those of the amphibs to shame. They are letting SWOs go there in limited numbers now. The carrier nuke SWOs call the non-nuke SWO ship's company, "nuclear waste."
