Storm Shadow and SCALP are both 250km (the one Ukraine is using) but Taurus has a range of supposedly 500km. Storm Shadow's export version has always been less than the 500km internal version, I wonder if the hold up with Germany is that they are thinking about sending the 500km version so they want America to send ATACMS which is 300km...But that would be stupid because that's only 50km more than the Storm Shadow/SCALP they currently have.
Likely I'm wrong though and Taurus will be nerfed like Storm Shadow/SCALP down to 250km..
