These massive ships were the backbone of one of the earliest
pre-republic empires. Far larger than any of it's contemporaries,
the Ultimate dreadnoughts were capable of destroying opposing
cruisers with a single shot from it's lasers or heavy cannons.
These very powerful weapons couldn't lock on starfighters, and the
ship was therefore fitted with it's large numbers of light cannons
and torpedo tubes, and they would always fly with large fighter
compliments. The Ryeh Imperium fielded 300 of these ships at it's
height, and nearly twice as many slightly smaller Invincible class
dreadnoughts. After it's fall, almost all of these ships went from
warlord to warlord, and many wound up in the fleet of the fledgling
Republic, though at that time they weren't quite the ultimate war
machines that they once were.
There are relatively few uses for a Ultimate dreadnought in
modern times, though many of it's parts still command high prices.
The hand tooled cannons, the gold and duridium detail work, the
opulent captains's quarters and other items are particularly
valuable, but even the refined titanium/carbon alloy hull is worth
quite a bit. The value of a Ultimate Dreadnought in good condition
to a collector would be quite high, assuming that a collector could
be found that is interested in capital scale ships.
