Klingon Bird of Prey
Second version - The Bird of Prey was first seen in the movie Star Trek III: The Search for Spock. This has become perhaps the most common Klingon ship design in modern Star Trek. It is much smaller than the D7 and K't'inga class cruisers. Standard crew complement is a dozen officers and men (stated by Hikaru Sulu in STIII).
Birds of Prey are fast and agile warships. They are the ship of choice for espionage and spy missions, and many Klingon commanders prefer to command them over the larger vessels in the fleet. The wings are movable and have three main positions: slanted down for battle, raised slightly above 180 degrees for cruising, and raised very high for landing (the Bird of Prey is one of the few starships that enter a planet's atmosphere and land on its surface; Federation Intrepid-class ships are another). Some designs incorporate a submarine-like periscope for the captain that also has weapon controls on the handles, allowing him to aim and operate the weapons himself; this design also featured movable disruptor cannons (this design was shown in Star Trek V: The Final Frontier and Star Trek Generations).
