The Mark VI warp drive was a version of warp drive engines installed on the older Excelsior-class starships.

In 2369, this drive was named on the chart "Sector Ipai Relay Log – Relay Message Flow 1293" in Relay Station 47 Ops. The USS Hood was assigned a mission where the ship would perform warp power testing on its engines. (TNG: "Aquiel", production art)
