Superchimp

The superchimps, sometimes abbreviated to simp, are a brand of monkeys that have been genetically modified by the Superchimpanzee Corporation for menial spaceship labor. The cost of developing and creating them is high enough that it's only cost efficient for the space industry, where each chimp can do the work of nearly three trained cosmonauts. Their docility and relatively high intelligence allows them to somewhat understand speech and perform the most repetitive tasks of maintaining a crewed spaceship.
