Formerly used by the aliens to transport large amounts of supplies, resources (and quite possibly human prisoners/test subjects), this vessel was captured by the reborn but still fledgling XCOM, who soon used it to begin linking up with scattered resistance cells and coordinate their campaigns against ADVENT.
The Avenger functions similar to XCOM's previous underground base, using an "ant farm" interior design to harbor the barracks, labs, infirmary, etc. However, being a fully mobile aircraft, the Avenger can swiftly travel across the globe, instead of being confined to a single location, allowing it to either scan a local area or deploy a squad aboard the Skyranger.
There is also a mission during the campaign that involves the Avenger, but does not take place within the ship itself.
The Avenger features a several static facilities:
There are 12 rooms in the Avenger that can be cleared to allow the player to build additional facilities from the list below. Most facilities can be upgraded to provide extra output. The values for an upgraded facility are in parenthesis.
There are clarifying notes below the chart.

NOTES about Chart Data:
- Upgrading a facility is instantaneous, there is no construction time.
- Number of possible Engineers (or Staffing Gremlins, if adjacent to a Workshop) that can be staffed in each facility, when Engineer(s) are staffed in a facility they provided additional resistance contacts, defense turret stats or reduction % time in their respective facility (See Output Description).
- Power Relay Upgrades:
- Power Conduit: +2 Power [normal Power Relay] OR +9 [when upgrading a Power Coil Relay room]. Adds an additional workstation, allowing an additional Engineer to be staffed. Costs: 80 Supplies
- Elerium Conduit: +? Power [normal Power Relay] OR +13 Power [when upgrading a Power Coil Relay room]. Costs: 150 Supplies and 20 Elerium Crystals.
