Umbilical

Umbilicals are corridors extending out from a vessel or space station to serve as docking points for other ships.

Overview
In addition to the systems on UNSC ships and stations, many Covenant vessels, including the Ministry of Tranquility's missionary ships, are equipped with umbilicals.

Cairo Station Umbilicals
During an award ceremony on the orbital defense platform Cairo Station just before of the Battle of Earth, the frigate was docked in Cairo's portside umbilical. John-117 cleared the umbilical en-route to the Covenant bomb in Firing Control. This allowed Commander Miranda Keyes, Sergeant Avery J. Johnson, and Commander Keyes' bridge crew to board the In Amber Clad and join the battle above Earth.
