Klingon bird-of-prey (22nd century)

The Bird-of-Prey was a Klingon type of starship used by the Empire's Defense Force in the 22nd century, one of the early ships in the long line of Klingon Birds-of-Prey. 

Design
Nimble bird-like craft known as birds-of-prey had been an essential part of the fleet since the Klingons achieved spaceflight. While the design was adapted to become more and more powerful, the basic layout of an engineering hull with a pair of wings and a bridge module connected by a long neck to the primary hull remained consistent. Like their precursors, the Bird-of-Prey of the 22nd century served as scouts and raiders. ( #35)

In the early 25th century, the - and Birds-of-Prey designs harked back to their earlier counterpart. The pointed bridge module and the dorsal superstructure on the engineering hull were reminiscent of their precursor. 

Size
At a length of 145.36 meters, the Bird-of-Prey was smaller than the - and battlecruisers and often served as escorts to them. ( #35)

The Birds-of-Prey came to perform the roles of patrol ships and scouts and eventually supplanted the smaller in the 2150s. ( #41)

22nd century Birds-of-Prey have a substantially higher number of disruptor banks compared to their later relatives however one assumes the disruptor cannons of later variations would be somewhat more powerful.

The Bird-of-Prey is a formidable opponent, but does possess one Achilles-heel: a direct hit on the main plasma junction above the sensor array can disable the entire power grid, at which point the vessel can be easily neutralized. 

History
The Birds-of-Prey in operation in the 22nd century are the earliest Birds-of-Prey known to be used by the Klingon Empire. Birds-of-Prey have been used in a number of engagements with Humans and one was even stolen by a group of Human Augments in the year 2154.
