"Sailor" is still commonly used (even in official contexts) to describe personnel on modern naval vessels.

Sailors aren't on deck during a battle any more, so are unlikely to be suffering laser reflections (!) from tiny projectiles thousands of yards away.

Most warships (of the non-submersible variety) have windows, last I checked. In fairness, though, that does make it easier to mitigate that issue.
