The Ausmerzer is a large fortified airborne platform used by the Nazis to transport troops. It is first seen during the attack on the Eva's Hammer at the beginning of Wolfenstein II: The New Colossus and subsequently plays a significant role in the game's plot.
The Ausmerzer was built and put into service around 1951, as a sort of "guard" of the new American order, similar to the London Monitor in Britain. Irene Engel was given command of the Ausmerzer around 1960; she used it to track down the resistance-controlled Eva's Hammer in the northern Atlantic ocean, by following signals transmitted by Nazis hidden inside Section F of the U-Boat. It is unknown if the Ausmerzer is the only platform of its type or if others are present in different parts of the world.
In 1961 the Ausmerzer was wrested from Nazi control in a joint operation by the Kreisau Circle and two American resistance cells led by Grace Walker and Horton Boone respectively, to prevent it from resuming its former role in crushing large-scale resistance to the Nazi regime during their planned uprising. Sigrun Engel provided them with the password to override the airship's automated defence systems and William J. Blazkowicz and Anya Oliwa subsequently slaughtered the troops on board in their usual fashion; resistance hands it will presumably be turned against its former masters during the Second American Revolution.
Befitting its role as a counter-insurgency platform Ausmerzer is highly mobile, patrolling from city to city across the vast breadth of the continental United States. It transports a large complement of troops including conventional infantry, Super Soldiers, robot troops, at least one Panzerhund, a Zitadelle unit and even two Zerstörer robots; it even carries smaller vehicles, including a complement of Silberfish submersibles.
In addition to its garrison the ship itself is heavily armed - known weapons include flak cannons on both dorsal and ventral mounts, deck-mounted artillery cannons, depth charges for attacking submerged targets, ventral launchers loaded with air-to-air missiles and even rocket-propelled transport pods used to rapidly deploy Super Soldiers into battle. It's hardened against electromagnetic pulses, as demonstrated when it still remains operational in close proximity to a nuclear explosion in New Orleans, and it can deploy extendable cables fitted with claws or large magnets to grab objects below it; its engine power is such that in addition to lifting its own mass it can uproot an entire house from the ground or forcibly surface submerged U-boats when the cables are deployed. It is also known to be equipped with radar.
Operation of the Ausmerzer is heavily automated by way of the ODIN computer system. The interface for this system is divided into a main control centre and the subsidiary HUGIN and MUNIN control centres which control the port and starboard side defences respectively. While it was touted to the public as a sophisticated control system, at least one technician who worked on the Ausmerzer suggested the ODIN system was quite outdated and in need of modernisation by 1961; this was never actually done as it was decided that the airship would be too vulnerable without its automated defences during the refit. Despite the Ausmerzer's high strategic value the computer security for ODIN is less than stellar: all three control centres have the same password, namely the word "Valhalla", which when entered allows complete control over all systems slaved to that computer.
- It is speculated that platforms such as the Ausmerzer have replaced, or will come to replace, the more traditional Zeppelins seen in previous games.
- The names assigned to the automated defence system reflect the Nazis' frequent appropriation of names and imagery from Norse and Teutonic myths:
- ODIN is of course named for Odin the All-Father, the ruler of the Norse gods.
- HUGIN and MUNIN take their names from Odin's two ravens, which fly around the world bringing information to him - reflecting how the Ausmerzer under Engel's command flies around the world seeking information on the Kreisau resistance and William J. Blazkowicz.
- The password "Valhalla" references the mythological realm believed by the Vikings to be inhabited by warriors who die in battle.
- The concept of the Ausmerzer is likely inspired by the Helicarrier from Marvel Comics but its appearance draws more influence from the the HK Aerial from the Terminator franchise.
- The Ausmerzer gets its name from the German verb "ausmerzen" which means "to weed out" or "to eradicate", which aligns with its mission to eliminate any sign of resistance to the Nazi regime in the United States.
