From what I have seen The navy is not showing any harpoons being loaded on any of our subs. As for the tubes the are all the same 8-660mm torpedo tubes.But sea wolf was designed for
50
Tomahawk cruise missiles or
50
Harpoon antiship missiles or
50
Mark 48 ADCAP torpedoes or
up to 100
mines
as for the harpoon I haven't heard about it beeing able to launch from a VLS tube but I wouldn't see a problem. And remember your not being picky your paying attention to detail.
