Oberon-class Battleship - Notable Oberon-class Battleships: Justus Dominus - The Justus Dominus was accompanying fourteen transports alongside the Devastation-class Cruiser Righteous Fury and six escorts in the 37th Millennium, during the Mordian Incident. The Righteous Fury reported a presence on its long-range surveyors and launched its fighters and bombers to intercept. This was a devious ploy for the Righteous Fury to launch all of its bomber wings. As they passed alongside the Justus Dominus, the attack craft suddenly altered course, perpetrating a devastating bombing run on the powerful warship. Crippled by this surprise attack, the Justus Dominus was unable to assist as the Righteous Fury turned its guns on the smaller escorts, destroying four and forcing the two survivors to withdraw. The transports were helpless against the traitorous cruiser and after 13 hours of successive attack runs from its bombers, the Righteous Fury had destroyed all fourteen transports. The Righteous Fury was renamed the Unforgivable by its Traitor crew.Green Lake - The Green Lake was an Oberon-class Battleship that fought in the Third War for Armageddon. It scored several victories over Ork ships, including destroying the space hulk Skullbanga before itself being destroyed by a teleporter attack by the Ork Battleship Dethdeala.Light of Truth - The Light of Truth is an Oberon-class Battleship recently commandeered by Inquisitor Tane Massata of the Ordo Malleus. It served as his flagship on his mission to the Knight World of Adrastapol. For several Terran years, the Light of Truth and her fleet lurked outside the Majestis System while the Inquisitor conducted his covert missions to retrieve an artefact of Chaos. His plans foiled, Inquisitor Massata ordered the Light of Truth to conduct a hit-and-run campaign on the vessels of WAAAGH! Killfist, rerouting the Ork invasion to Adrastapol as a cover for his own expedition. Before he departed, the Inquisitor left standing orders for the Light of Truth to enact Exterminatus-protocols. Having changed his mind regarding the culpability of the Knight Houses of Adrastapol while planetside, Inquisitor Massata contacted his flagship, aborted his previous orders and ordered the Light of Truth to join the fight against the Orks. In the subsequent void battle, the WAAAGH's naval elements were hunted down and destroyed, ending the Battleship's mission with a resounding victory.Thunder of Heaven - An Oberon-class Battleship of Battlefleet Tempestus that fought in the Dark Marches Crusade of the 36th Millennium.Tomioka - The Tomioka was the flagship of the lost Magos Telok who vanished behind the Halo Scar in the 36th Millennium, never to be seen again until the venerable Oberon-class Battleship was found mysteriously abandoned on a dying planet that orbited an end-sequence star beyond the galactic fringes.Execution Eternal - The Execution Eternal is an ancient Oberon-class Battleship lost to a crew mutiny in the early ninth century of the 41st Millennium while on a mission to reinforce Imperial armies fighting on the Achilus Crusade's Greyhell Front. The ship's officers were murdered, but not before they could sabotage the Warp-Drives, preventing the mutineers from fleeing with the ship. T'au forces learned of the ship's plight and sent a Hunter Cadre to capture it, but the Imperial Navy sent its own mission to recover it and the resulting battle raged through the countless decks of the starship. It is still going on, with the T'au holding the cavernous engine chambers and the Imperial Navy troops holding the bridge and crew decks.Precept Magnificat - The flagship of the Indomitus Crusade Fleet Tertius, under command of Cassandra VanLeskus, chosen by Roboute Guilliman himself to serve as its fleetmaster.
