Nobody doubts you can do it on a ship - that's self evident. It's the amount of emb8ggerance you cause to the deck park and subsequent operations in doing so.....
That raises the question of why you'd want to do it operationally, if you have to clear the entire aft end of an LHD, or reduce the safe parking area on a CVN. That's why statements like "The MROL technique was validated in the shipboard environment" are a little disingenuous and ought probably to say something like "validated in a shipboard trial environment".....
