The Klingon escape pod was a type of emergency escape craft installed aboard warships in the Klingon Imperial Fleet during the mid-22nd century. Some Klingon vessel types, such as the Raptor-class scout ships, were not equipped with escape pods. (ENT: "Sleeping Dogs")
In 2153, Captain Jonathan Archer, after being captured by the Tellarite bounty hunter Skalaar and subsequently handed over to Klingon captain Goroth, used this type of Klingon escape pod to leave Goroth's starship. He was later rescued from the pod by Enterprise NX-01. (ENT: "Bounty")
In 2154, Doctor Arik Soong used a Klingon escape pod to leave his captured Bird-of-Prey following Malik's attempt to claim the ship for himself. Doctor Soong was later picked up by the crew of Enterprise NX-01. (ENT: "The Augments")
