Last I read Israel had three German submarines that can be outfitted with nuclear tipped cruise missiles. Unfortunately their (missiles) range is only 90 miles. Plus only three nuclear warheads per submarine due to radiation concerns.
Well I think there's a bit of (deliberate) confusion on that.Some sources say that the nuclear tipped missile is a modification of the American Harpoon which is highly unlikely given it's range & small warhead.Most others say that the missile is a dedicated cruise missile,the Popeye Turbo(Popeye-3) which was testfired off India's coastline(Surprise!!) in 2000.Now lots of guesstimates of the range of the Popeye Turbo range from 350 kms to 1500kms.The size of the missile makes sense given that the Dolphins have around 4 650mm torpedo tubes,which are not exactly common on D/E subs.
