The following is based on Fallout Tactics and some details might contradict canon.
The Acme company was a defense contractor for the American government. As per contract 10056-567, it designed, manufactured and supplied humanoid combat robots for the U.S. military.[1]
Behind the scenes[]
Many companies named Acme were founded in the 20th century, as they would be some of the first businesses listed in alphabetically arranged telephone directories. This trend inspired the naming of the fictional Acme Corporation in many Warner Bros. cartoons.
The word acme is derived from the Greek ακμή, meaning peak or zenith.
