Hegh'ta 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 Hegh'ta class heavy Bird of Prey brought everlasting death to foes of the Empire. The class 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 four forward-facing and two aft-facing weapons emplacements.[1]
