theoretically an SM-2 Block III may be able to fit in a Mk-13 launcher - within a few inches to spare.
Yes it can, but I haven't bashed one together, and as far as I know, the USN never deployed the SM-2MR in the manner. If someone wants to they could try and bash one together and it might make it to the sheet, I'd have to see what it looks like.
I enlarged the front views of Harpoon's launchers. Isn't more good according the others views in the drawing !?
Thanks for comments.
I'm not sure the change is in order. If you have some scale drawings of the Mk-141 then I'd consider it, but right now I'm going to stick with the recent version that has been drawn.
