Sojourner-class dreadnought

Forerunner Ship

These Unnamed Forerunner Starships are warships used by the Forerunner Navy.

Complement
Not much is known about the weaponry or combat capabilities of these ships. The planetside docking towers for the ships can detach from the ground, and hover above the surface of a planet. In space combat, the ships are capable of arranging themselves into a hexagonal formation, and can then combine their energy weapons into a single blade-like beam. This beam has been shown to effortlessly slice other ships in two.

History
These warships were common during the Forerunner-Flood War, used widely in combat operations. Among numerous other docking facilities around Forerunner-controlled space, these ships were docked at the Apex Installation, located on the Flood-Controlled Shield World.

During the Human-Covenant War in 2531, the High Prophet of Regret and the Arbiter went to the Apex to gather a massive and powerful invasion fleet for the Covenant Navy. In order to release the locking mechanisms holding the ships in place, they needed a Reclaimer. Thus, they abducted Professor Anders to activate it for them. The ships were destroyed when the artificial star inside the Shield World went Supernova.

Trivia

 * Parts of these ships can be seen on the outer surface of the Shield World, suggesting that a battle may have occurred between the Forerunners and the Flood on the Shield World during the Forerunner-Flood War, resulting in the installation's infestation by the Flood.
 * These ships have a slight resemblance to some large structures found on the Ark.
 * When the cutscene "Judgment Day" is highlighted in Halo Wars theater, the ships are described as Forerunner Dreadnoughts. While the only remaining Keyship is widely referred to as the Forerunner Dreadnought, the name "Dreadnought" may refer to a class of ships rather than a specific type. It may also be that "Dreadnought" is not an official designation at all and that the term is simply used to describe the massive scale of the ships.
 * These ships are also seen in Halo Legends episode Origins Part One.
