New Sparta Air Department has said it will withdraw all 150 K-18D close support aircraft next year. It likely they will be sold back to the Dinos. The reason for the withdrawal has not been given though the K-18Ds have not been that popular with the Air Department since they were bought off the Dinos in 2110. The K-18Ds were localised for human use though many parts of the aircraft were still optimised for Dino anatomy and thus crews have found them awkward to use at times.
NSAD has 120 A-12 NDAA and 105 A-85 COIN aircraft in service and consider they have sufficient close support aircraft for their needs. The K-18Ds will be withdrawn early in 2123. The squadrons will be disbanded and crews transferred. A new close support aircraft, the OA-25, with a ducted fan is in development. This will replace the A-85 and allow A-12s to be moved to the attack role.
