J-Type Royal Starship
Once again, thanks to the inclusion of the Naboo in Episode I, we get what might be a very good indicator of life on the whole in the era of the Republic, this time as applied to space vessels. The Royal Starship of the Naboo Queen is a sleek, elegant example of spacefaring technology that has obviously been a labor of love for its developers in the Palace, who, even though they themselves didn't build the Nubian 327 hyperdrive, made the effort to tune it and modify it to perform past it's normal parameters (hence the improved Hyperdrive Multiplier). The Prequel Era, while not without its dangers, is still one of a theoretical peace, and governments all over the galaxy most certainly must employ similar vessels: unarmed, but very functional, pieces of artistry melded with fine engineering. This is a craftsman's era, after all, and in this time, diplomatic vessels are supposed to be unarmed (admitting that piracy exists in the Republic is somewhat frowned upon as the sagging Senate tries to deny the general decline of things; therefore, shields are OK, but weapons are looked at with disdain).
Let me turn you over to David West Reynolds one more time for some background information...
"The Royal Starship of Queen Amidala of Naboo is a unique starship handcrafted by the Theed Palace Space Vessel Engineering Corps. Completed six years ago, the Royal Starship replaced the previous royal vessel before Queen Amidala came to office. The gleaming craft, usually helmed by the Queen's chief pilot Ric Olie , conveys Queen Amidala in matchless style to locations around Naboo for royal visitations, parades, and other observances. The ship also carries Amidala on formal state visits to other planetary rulers or to the Galactic Senate at the capital world of Coruscant itself. It is designed for short trips, and accordingly features limited sleeping facilities, primarily dedicated for the ruler and a customary entourage.
Expressing the Naboo love of beauty and art, the dreamlike shape of the Queen's ship, together with its extraordinary chromium finish, make it a distinctive presence in any setting. The starship is made to embody the glory of the Naboo royalty, symbol of the noble spirit of the Naboo people. Sevice to the Queen is a great honor, and the design of a Royal Starship is the highest goal to which a Naboo engineer can aspire. Every centimeter of the ship's wiring is laid out with exacting precision, neatly run in perfect parallel rows, making the ship a work of art in every respect."
As you may recall, the chromium finish on certain Naboo vessels is indicative of a Royal connection, and the Queen's Royal Starship is the only such vessel to be finished entirely in the mirrored chromium, which is lovingly hand-crafted by skilled artisans. Even the hyperdrive core, in most ships little more than a mass of components and tangled wires, has been refined into an elegant-looking centerpiece of sheer art, with its intricate mazes of effect channels and charge planes enhancing both its appearance and its performance.
A GM could safely use the stats for the Naboo Royal Starship for any high-ranking official's personal transport vessel, or even change the dimensions and scale to a capitol-scale vessel to create a wealthy individual's pleasure cruiser.
