J-type 327 Nubian Royal Starship (Earth-2356)

The J-type 327 Nubian Royal Starship is a starship model designed and built by Nubian Design Collective. They use a sublight engine and a T-14 hyperdrive generator, also designed by Nubian Design Collective. The T-14 hyperdrive gave the J-type 327 Nubian a hyperdrive rating of 1.8.

The Naboo Royal Starship used by Queen Padmé Amidala was a modified J-type 327 Nubian starship, due to the unique spaceframe being built around an imported Nubian sublight engine and T-14 hyperdrive. It therefore had to use J-type 327 Nubian parts. In the era of the Galactic Empire, Sith Lord Darth Vader came to own Amidala's starship.
