Mirror Universe Ha'apax Advanced Warbird
 Ha'apax class
The Ha'apax class and its sister classes represent a notable design departure from such classes as the D'deridex and Mogai. The ship's main hull is much bulkier and more solid than preceding classes, with no internal space like the D'deridex. The enormous wings arch downwards (reminiscent of the Dhelan Warbird) to meet with the secondary wings (which, when the Dual-Vector Separation Universal Console is equipped, become the wings of the Assault Warbird component), and the "head" looks to be patterned somewhat after a Bird-of-Prey such as an eagle. Indeed, when viewed from directly above or below, it becomes obvious that the ship's shape and design are strongly reminiscent of a Bird-of-Prey in flight.
The Mirror Ha'apax performs (unsurprisingly) much like the Prime Universe Ha'apax Advanced Warbird in playstyle. The key difference is that the Mirror Version has a strong Science focus in its Console and Bridge Officer setup, detracting from its Tactical side. While this can lower the ship's offensive potential somewhat, the trade-off is access to more high-level Science abilities, something that can turn the Ha'apax from an ideal tanking ship to a great healing ship, something that is very useful in STF missions and other team play missions. This does come at the expense of Tactical focus in Bridge Officers and Consoles, so players should not expect great DPS potential.

 Standard Configuration
Romulan starships come with standard equipment and weapons of the lowest mark available at the ship's minimum rank. The items provided are appropriate to the type of vessel and its related playing style.
All Romulan Warbird vessels are equipped with an advanced version of the cloaking device, a battle cloak, that can be activated whilst at Red Alert, giving the Mirror Universe Ha'apax Advanced Warbird a significant advantage.
Romulan Warbird vessels come with built-in Singularity abilities. These abilities do not automatically rank up when acquiring higher tier Warbirds. These powers build in severity based on the charge built up by the ship's Singularity Core.
