Thanks.

I don't think the fleet would make the best target. Ukrainian territory or not, the Sevastopol military base was always Russian (initially on rented ground, then in annexed Crimea). NATO has no real interest in attacking Russia itself, and will probably avoid even appearing to.

If it intervenes directly (still a big if), I'd mostly guess strikes against Russian bases inside Ukraine - that's the least interpretable action, and technically it's even an obligation for US under the Budapest Memorandum. The George Bush carrier strike group is currently in the Adriatic Sea, with eastern Ukraine barely within Tomahawk range, flying over NATO countries only.
