The T-400 was an experiment by Skynet to field test elements of the Terminator design would later be used in endoskeletons. T-400 represented a successful attempt to create a materially cheap soldier that could be manufacture in obscenely large numbers (millions). This was intended to keep the human resistance busy long enough for Skynet to hide and secure its manufacturing plants and the various mainframe hubs which stored the Skynet's consciousness. There were so many T-400s built that by 2029 they were still being used as prison sentries, while other previous Terminator models had been all but wiped out by the resistance. Due to the considerable noise these models made while moving about they came to be nicknamed "clunkers" by the resistance.

Note: The original production run of the T-400 was in the millions.

Series 40 Integrated Logic Package. The Series 40 ILP CPU was a very basic Terminator brain, allowing weapons targeting, navigation, and very limited autonomy. The greatest achievement of the 40 ILP was a stripped down nervous system that allowed for the units to balance themselves while walking. This was basically a consolidated platform based on the AI of the T-70, made in a smaller fabrication process with all additional features removed.

This chip did not have a suicide feature, which was a mistake on Skynet's part as the primitive design bared many of the hallmarks of the Neural Net architecture of the later Terminator models. The resistance was able to reverse engineer these chips and from that knowledge was then able to eventually reprogram more sophisticated hunter killers as well.

These units had just enough volatile memory to follow simple instructions issued to them by Skynet and to navigate the ruins of various urban areas. Together with the T-500, the T-400 was simply designed as a stop gap to keep the human resistance off balance while Skynet worked in secret perfecting the true Neural Net CPU Learning Computer that would be installed in later deadly Terminator models.

Like the T-500, the T-400 was capable of distinguishing between its targets and other Terminators. Significantly more intelligent than an insect, it was capable of following verbal commands.

T-400s exhibited aggressive and impulsive behavior, not unlike apes.

2 modes of operation:
  • direct (directed by Skynet defense computers like soldiers in a war game); and
  • automatic (individual units acting automatically to a variety of preprogrammed conditions).
Technically, T-400s could also be set to an autonomous mode, but this was not often used due to their tendency to inadvertangly damage Skynet manufacturing facilities when not supervised.

CONCEALMENT - Not applicable.

CAPABILITIES- In addition to the above listed capabilities the 400 Series has many features. Capable of pressing roughly 1000 pounds and traveling on all terrain with little difficulty. The greatest asset of the T-400 was in the great numbers it was produced in. Destroying ten or fifteen of these plodding menaces was no great feat, but destroying an army of 50,000 units sprawling about the landscape could be taxing of manpower and resources.

One purpose of the T-400 was to break through physical barriers and blockades that the resistance erected so that more effective but less mobile soldiers (such as the T-1s and Fast Walkers) could then advance and exterminate humans. However, this programmed behavior was often used inappropriately by these androids resulting in the robots walking into buildings, knocking down load baring members with their great strength, then being flattened or buried when the buildings collapsed. Finally, one of the greatest features of the T-400 was that Skynet could afford to use them to detonate resistance landlines.

CONSTRUCTION- Steel framed with ceramic / tin-plated armor and some aluminum components. One single optical sensor. Shoulder mounted plasma-based weapon. Exposed wiring.

WEAPONRY- The T-400 was issued light plasma phase weapons permanently attached to their shoulders (so that they would not lose them).  In order to hit a target the T-400 unit had to be directly facing that target. Multiple targets could easily confuse

  • No depth perception.
  • Predictable aggression.
  • Single optical sensor glowed bright red, making an excellent bullseye for a sniper.
  • Only capable of the most simplistic mental processes.
  • Susceptible to rust and corrosion.
  • Many spots vulnerable to conventional artillery.
  • Can be detected by animals at great distance.
  • No self-preservation programming (sometimes would walk directly off of cliffs or blow themselves up by stepping on clearly visible claymores).
  • Most of the capabilities of the T-400 were actually outstripped by previous models, especially their targeting system and weapons.
  • The capabilities of the T-400 to operate autonomously was negligible. Their greatest asset was in their large numbers.
  • T-400s were very loud and made a distinctive "clunking" noise while marching.
  • Permanently attached weapons systems were awkward to aim at targets.
  • Although far stronger than a human being, a T-400 could be defeated by an unarmed human who was familiar with the weaknesses of the model and used its weight against it.
