Is the warship of Mary biblical?

Sort of.

A warship is, of course, a ship used primarily for military purposes. "Mary" is a name that can mean beloved but can also mean "the sea of bitterness." In Hebrew, "sea" is a metaphor for chaos, which is a primary characteristic of war.

The vast majority of the ships mentioned in the Bible were for trade while the boats were for fishing. The Greeks and Romans had warships between the end of the Old Testament and the end of the New, but they aren't mentioned.

Daniel 11:30 and 40 may be the only verses in the Bible that mention warships.

Daniel 11:30 talks of the "ships of Kittim," or Cyprus, which Daniel prophesied would attack Antiochus Epiphanes while he was trying to invade Egypt. Antiochus withdrew and desecrated the Temple, instead.

Daniel 11:40 is part of a passage that does not match Antiochus Epiphanes, so many think it is about the Antichrist. He is attacked by the king of the North who has many ships. The "king of the North" in Daniel typically refers to the king of Syria, but it's not clear who this will be during the Tribulation.

So, whether you mean a warship on the sea or a warship in the chaos of war, they can be found in the Bible, once in a prophecy that has already be fulfilled and once in a prophecy that apparently is yet to come to fruition.

Even so, the "warship of Mary" is not explicitly found in the Bible. The mother of Jesus does not have—and has never had—a literal warship of her own. It is not a good idea to depend on Jesus' mother when engaged in naval warfare. Do not depend on her, pray to her, or worship her.

That being said, the Brits did have an ocean liner named the RMS Queen Mary that was converted into a troop carrier during World War II. But that ship isn't in the Bible, either. And a troop carrier isn't, technically, a warship.
