Alternate timeline
(covers information from an alternate timeline)

In another quantum reality, a Bajoran ship was a type of starship utilized by the Bajorans during the late-24th century.

Following their overthrow of the Cardassian Union, they used these ships as they became more aggressive, even going as far as attacking Starfleet.

In 2370, a Bajoran ship destroyed the Federation's Argus Array, believing that it was being used to spy on them. A day later, the ship attacked the USS Enterprise-D, causing damage to its power systems.

The ship later disengaged after the appearance of approximately 285,000 near-duplicate Enterprises which appeared following a series of quantum incursions into that reality. (TNG: "Parallels")

The Star Trek Customizable Card Game Second Edition Fractured Time expansion names this ship the B'tanay and calls it an Ornathia-class" ship. The card displays an image of a modified Bajoran assault vessel.
