Or go with the flow? Peter Rowan was at the Railway Institute Hall Thirroul a few years back. You should'a been there. (His bass player is a nuclear engineer with a proper day job)
Not sure what we are worried about. In 20 or so years when the first one arrives we'll already have come to the conclusion that we really don't need any more and we'll cancel the contract, that's if Donald hasn't already done so when he comes back (?) to the White House. We can then go for satellites which we will be able to buy from Amazon or the local Tesla's corner store, team them up with the latest drone system and be able to do all the 'great' things that submarines once were able to do - what ever that was?
