Grievous' DH-Omni Support Vessel

During the Clone Wars, specifically in 19 BBY, a DH-Omni Support Vessel was under the command of Separatist General Grievous during the mission that took place on Utapau.

Grievous acquired a substantial kyber crystal during the aforementioned mission, which he then transported onto the Dual Hemisphere-Omni Support Vessel. Galactic Republic Jedi Generals Anakin Skywalker and Obi-Wan Kenobi pursued Grievous using a hijacked freighter, ultimately boarding the Support Vessel via the freighter's escape pods. As the Jedi escaped the freighter, they set the doomed ship on a course to ram the Vessel's hyperdrive, with the goal of preventing Grievous from escaping.

Once aboard, Grievous captured Kenobi, making him a prisoner. Two OOM-series security droids informed Kenobi that they were escorting him from his [prison](/article/prison] cell to the "execution room," prompting the Jedi Master to express surprise that they possessed an entire room dedicated to capital punishment. Kenobi then stalled for time by informing the droids that the Yavin Code mandated that all prisoners be blindfolded before execution, as Anakin was on his way to rescue him. Skywalker then came to the Jedi Master's rescue and destroyed the droids.

Kenobi and Skywalker engaged Separatist battle droids in combat throughout the Vessel, eventually encountering a group of Armored Assault Tanks. General Kenobi seized control of an AAT and fired its laser cannon at the massive kyber crystal. This action triggered a significant explosion that ultimately consumed the Omni Support Vessel and a large portion of the Separatist fleet positioned above Utapau. Skywalker and Kenobi made their escape aboard a Neimoidian shuttle, while Grievous fled into hyperspace aboard his starfighter, the Soulless One.
