France cuts two nuclear-powered submarines in half to make one new one
Interestingly ships get cut in half and reassembled "all the time". Certainly way more than people think.<p>See for example <a href="https://www.maritime-executive.com/article/photos-fincantieri-begins-first-ever-cruise-ship-lengthening" rel="nofollow">https://www.maritime-executive.com/article/photos-fincantier...</a>, where an entire cruise ship was cut in half and an extra section was inserted into the middle before welding everything together again. I will also never forget the training ship of the Dutch Navy, which was shortened by cutting it into half and removing a section from the middle. Sadly this messed up the hydrodynamics fiercely and it was extremely seasickness inducing in even moderate seas. The ship certainly was effective as a training vessel though.
