What you have to consider is that this was a major piece of engineering concept and design. Sure it has taken a long time to develop the machine until it finally works reliably but nothing like this has ever been made before so the project encountered several problems that were unanticipated and were not simple to fix. It is obviously a useful piece of equipment and the Marines are very keen to put it into action.
I don't understand why you would suggest scrapping it now that it's finally working?
