Like the Delta-7, the Delta-12's abilities were limited by the technology available when it was designed. Due to its relatively small size, the designers were unable to fit a hyperdrive engine inside the ship's body and were forced to use a hyperspace ring, specifically the Syluire-31 Hyperspace Docking Ring first used on the Delta-7 Aethersprite. The ship was too small for a full size astromech droid socket; specially designed stripped down R4 series droids were integrated directly into the fighter instead.
While originally designed for civilian use, the Delta-12 proved to be immensely popular with the Jedi Order. The Jedi often used the ship for diplomatic and passenger transport missions where its speed and, at the time, superior manoeuvrability was an advantage. The ship's signature red and white colour scheme was popularized by the Jedi; since the Jedi Order was technically part of the Galactic Republic's Judicial Department, they painted their ships red and white indicating the Jedi's diplomatic immunity.
