IKS Bortas (Vor'cha class)

The IKS Bortas was a Klingon Vor'cha-class attack cruiser in service during the 2360s.

In 2366, the USS Enterprise-D was contacted by the Bortas when Captain Picard requested reinforcements prior to entering the Romulan Neutral Zone to investigate a potential Romulan military base on Nelvana III. (TNG: "The Defector")

The Bortas was later Gowron's flagship during the Klingon Civil War in 2367-68. It took heavy damage during a surprise attack by ships loyal to the House of Duras at the beginning of the war, but drove off the attackers with assistance from the IKS Hegh'ta. (TNG: "Redemption")

In late 2369, Gowron traveled aboard the Bortas to rendezvous with the Enterprise-D when the latter ship was transporting the Kahless reincarnation to Qo'noS. (TNG: "Rightful Heir")
