Duras sisters' Bird-of-Prey

The Duras sisters' Bird-of-Prey was a D-12 class Klingon Bird-of-Prey operated by the House of Duras. It was destroyed in 2371 just after inflicting critical damage to the USS Enterprise (NCC-1701-D). 

Service record
This Bird-of-Prey was used by the Duras sisters from at least 2369 until 2371, in several missions.

In 2369, Lursa and B'Etor used the starship to provide Tahna Los with bilitrium. 

In 2370, Lursa and B'Etor used the Bird-of-Prey during their plot to steal magnesite in the Kalla system. 

While in orbit of Veridian III, Lursa and B'Etor staged a bold attack on the Enterprise-D in 2371. The Duras sisters had a considerable tactical advantage in knowing the Enterprises shield frequency, meaning that the Bird-of-Prey was able to render the Enterprises shields completely ineffective, allowing the Bird-of-Prey to score direct hits. The Bird-of-Prey was destroyed when the crew of the Enterprise exploited a design flaw in the D-12 class' plasma coils to force it to cloak and lower its shields in the process. Unfortunately, this proved to be a Pyrrhic victory, as the Bird-of-Prey was able to inflict critical damage to the Enterprise-D before being destroyed, resulting in a warp core breach and the eventual loss of the Enterprise. 

Background information
It is unknown if the ship seen in the episodes and the movie was the same Bird-of-Prey. Although differences in appearance of the ship's bridge - when comparing with  - suggest that the ship is actually two different vessels, it is also possible that the bridge underwent a radical redesign, as is implied as happening with the HMS Bounty between  and. Without direct evidence to confirm either possibility, this article assumes that it was the same starship.

Footage of the Bird-of-Prey being destroyed in Star Trek Generations was re-used from.
