I kind of had to wince at some early episodes like where they were supposed to on an Arleigh Burke, but the ship's crew wore hats for a DD (AB are DDG class ships), and then they were supposed to be firing a SAM from the Mk 41 launcher and they showed a Mk. 13 firing.
They got better the longer the series lasted, but a few of those early gaffs had me wincing miserably.
