K'Draq, daughter of Sangra was a female Klingon in the Klingon Defense Force in the 24th century. In 2376, she was first officer of the IKS Sturka under Captain Gatrell, during its mission of exploration and conquest of the Kavrot sector.
When the Sturka discovered several apparently pre-industrial worlds in the system Kavrot javmaH jav (Kavrot 66), K'Draq and and second officer, Grokla, theorized that the natives had some kind of organic technology instead. Gatrell ignored these warnings, which proved to be true, and forced the Sturka to retreat from the battle for conquest.
Gatrell blamed Grokla for this failure and had him put to death. When K'Draq then challenged Gatrell, the captain refused and had his bodyguards keep any other potential challengers away. K'Draq then made a report directly to KDF Command contesting Gatrell's formal record of battle. Her account was corroborated by other Sturka officers, and when General Kriz removed Gatrell from his command, he promoted K'Draq to Captain and made her commander of the Sturka.

K'Draq was still in command of the Sturka in 2381, when the Borg Collective launched an all out invasion. Captain Krogan and the IKS veScharg'a led a fleet including the Sturka against the Borg at Morska; although they were victorious over the Borg cubes, thanks to Starfleet's transphasic torpedoes, K'Draq reported that her ship had taken heavy damage, including loss of warp drive, and would not be able to join a fleet amassing to intercept an attack fleet heading for Qo'noS.
