Gravity lift



The gravity lift is a form of transport derived from Forerunner technology by the Covenant. A gravity lift can safely transport individuals or goods vertically without the need for a physical lift.

Operational history
During Operation: SILENT STORM in 2526, Blue Team uses gravity lifts leading from the fabrication barns on the Ring of Mighty Abundance to send HAVOK tactical nuclear weapons aboard the Covenant supercarrier Hammer of Faith and destroy it.

During the Fall of Reach in August 2552, Fred-104 and Kelly-087 use the gravity lift on a Covenant cruiser to send a Fury tactical nuclear weapon aboard the ship and destroy it along with the troops gathered underneath.

In September 2552, during the Battle of Installation 04, Spartan-II John-117 and several ODSTs have to fight their way aboard the Truth and Reconciliation using the gravity lift which is heavily defended by Covenant forces. Later, the Master Chief has to fight his way back aboard the battlecruiser using the gravity lift after overwhelming Flood forces causes the Master Chief to jump out of the ship. When the human forces later take control of the battlecruiser, the gravity lift is one of two methods of entry used to gain access to the ship. It is then deactivated as the humans prepare to depart Installation 04 in the Truth and Reconciliation.

During the early stages of the Battle for Earth, the Master Chief is ordered to reach the Solemn Penance's gravity lift to board the assault carrier and capture the Prophet of Regret. However, after the Master Chief destroys a Scarab, the Solemn Penance instead flees through slipspace to Installation 05. Later, the Master Chief utilizes the gravity lifts on High Charity to help move around.

Shortly after the departure of the Solemn Penance, ODST Taylor "Dutch" Miles helps other UNSC forces take the carrier's former landing zone which still contains the deactivated bottom of the ship's gravity lift.

In April 2559, as part of Isabel's plan to destroy the Banished Enduring Conviction, she has ground forces from the  take over the carrier's gravity lift while more ground forces use a particle cannon to take down the carrier's shield. Spartan Jerome-092 works to take the gravity lift with the help of Alice-130, hampered by Banished defenses sent down from the carrier using the lift. After positioning Kodiak tanks, the UNSC forces are able to take out the defenses around the gravity lift while Douglas-042 and Professor Ellen Anders take down the shields. Jerome and Isabel board the ship through the gravity lift and Isabel uses the Enduring Conviction's energy projector to provoke the Ark's Sentinels into attacking the ship. The Sentinels sever the ship in two, knocking out power to the gravity lift which ends up in the part of the ship Jerome is not in. With no other choice, Jerome is forced to jump from the ship to the surface of the Ark.

Applications
The Forerunners made extensive use of gravity-manipulating technology, including gravity lifts. This technology was eventually discovered and reverse-engineered by the Covenant. The usage of gravity lifts is commonplace in many of the Covenant's structures and installations, including their former holy city High Charity; there, gravity lifts served as the primary form of vertical transport, often in the form of long tubes that ran inside the city's towers.

Gravity lifts can also be projected from the underside of most Covenant starships. They can be used to lift ground-based troops and equipment onto a ship, or to safely transport troops to a planetary surface. Covenant citadels employ gravity lifts to lift supplies to and from orbit. before they are stored in the base's warehouses. They are also used as means of transport between the decks of ships. Some smaller craft, including Phantom dropships, some Spirit dropships, and Lich dropships, as well as deployable lookout towers are also equipped with gravity lift technology. Larger military emplacements such as spires possess gravity lifts for transport between the structure's various levels. Small, infantry-portable versions of the gravity lift are used by Covenant forces.

Variations
A variety of technologies employ gravity manipulation similar to gravity lifts; these include the man cannon, which propels individuals or objects in a tilted angle as opposed to a vertical span, or the gravity bridge, which consists of a horizontally-oriented gravity field.
