Jonathan J. O'Neill's Al'kesh was an Al'kesh stolen by Colonel Jack O'Neill and Teal'c and used to repair the Prometheus.


During a meeting with the leaders of the Jaffa Rebellion on P3C-249 in 2003, Colonel Jack O'Neill and Teal'c were stranded due to problems with the Stargate network at the hands of the Avenger virus. While communicating with Stargate Command, the camp was attacked by the Goa'uld. O'Neill and Teal'c survived and were able to steal this Al'kesh and travel to P5S-117, where Major Samantha Carter and Dr. Jay Felger were attempting to repair the Stargate network. When they arrived, the two were under fire from a Jaffa patrol. O'Neill and Teal'c used the Al'kesh to drive off the Jaffa. After Carter and Felger were finished repairing the Stargate network, O'Neill and Teal'c flew the ship to Earth. (SG1: "Avenger 2.0")

A few months later, the Al'kesh was taken to the planet Tagrea and the hyperdrive was transferred to the Prometheus in order to get it back to Earth. Despite the hyperdrive being designed for a ship much smaller than the Prometheus it was able to get the ship home. What happened to the remainder of the ship is unknown. (SG1: "Grace")
