A cloaking device is a form of stealth technology to render a starship or other object completely invisible.
This is a classic Star Trek characteristic for plot and an enemie's strategy & tactics.
(TOS: "Balance of Terror") in 2236 a Romulan bird-of-prey used the device
By 2269, the cloaking device had spread to the Klingon Empire
The classes and ships that have cloaking capability in Canon are:

* B'rel-class (Klingon Defense Force)

Will Orci & Kurtzman use a cloaking device on a ship in Trek XII?
If so will the Klingons use it or Romulans?
I think Trek XII will move on from the Romulans as the villian enemy.
