Norgh class (STO)
From Trekipedia
Birds-of-Prey were small, fast, and filled a variety of roles for the Klingon Empire. They could be used as scouts, raiders, or patrol ships. The Norgh class vessels were as deadly as the predator for which they were named. They featured a battle cloaking device, which could more rapidly cloak the ship than a standard cloaking device, including during combat. They were vulnerable when cloaked, but their speed and maneuverability made them hard to hit. The class mounted three forward-facing and two aft-facing weapons emplacements.[1]
