The 125a is a variant of the 100 series developed by Origin Jumpworks that alters the standard 100i touring design to focus on combat with the addition of a pair of size one missile racks. The power plant provides an increase in speed. It is most commonly used as a point defense or interceptor ship, but can also fly in support of larger assets like an Origin 890 Jump. The 125a's small size allows it to be stored aboard vessels which might not be able to carry or maintain a larger space superiority fighter.
