Plo Koon's Delta-7 Aethersprite-class light interceptor

Unlike many other Jedi in 19 BBY, Plo Koon reverted to flying a standard Delta-7 Aethersprite-class starfighter. This starfighter had a customized paint job similar to that on Anakin Skywalker's Azure Angel, marking the ship with distinctive blue-stripes.

History
A Jedi Master with a long, distinguished record of service, Plo Koon, from his seat on the Jedi High Council, helped see the Jedi Order through many trials in its twilight years. His tendency to see things in the stark terms of simple right and wrong served him well over the years, joining with his heightened extrasensory abilities it lent him a clarity of vision superior to some of the other Jedi. This clarity extended to his piloting; he was a straightforward warrior who was often seen at the head of a bombing run or diving charge. He was, however, unprepared for the subtlety of the Sith, and was blown out of the sky of Cato Neimoidia by his clone wingmen after the issuance of Order 66. It is said that his astromech droid, R4-F5, was ejected at the last second before the crash. This must mean that although his starfighter was a regular Delta-7, his must have been modified to have a full astromech droid socket on the port wing. This is debatable, however, since there doesn't appear to be room for the droid in the thin wing of the fighter and there isn't a compartment beneath it as there is in the Eta-2 Actis-class interceptor.

It can also be noted that earlier during the Clone Wars, Plo Koon was gifted a Delta-7B that was named the Blade of Dorin. This ship was marked with the same color scheme and design as Skywalker's Azure Angel. He flew with R7-F5 in this fighter. It is unknown why he switched from the Blade of Dorin to a standard Delta-7.
