In the orbit of the hidden colony "Oren" part of the UNSC's plan "Just in case" (PROJECT: SAFEHOUSE) the Covenant overrun earth, the UNSC was slowly amassing a fleet of Shatter-Class Super Carriers, armed with technology originally created for the Pillar of Autumn, .And with the capabilities of a Carrier, it is able to repair other UNSC ships while in battle, even though it strains the energy supply and output heavilly. When engaged in combat, if the crew chooses to repair another ship inside the carrier, the combat capabilities of the carrier were considerably weakened, as rapid repairs required alot of energy, meaning that the reactors could not sustain themselves, and the Carrier's computer systems automatically diverted energy from the MAC cannons, Engines and even lights became dimmer
