"The only thing more dangerous than a Dark Jedi is a Dark Jedi behind the controls of a Sun Crusher…"
―Han Solo, speaking of Kyp Durron
This is not an exact, but I tried hard. This is the Sun Crusher from the Jedi Academy trilogy of books. I know we would need to design a new cockpit, but overall I think I did well. The Sun Crusher was a nearly indestructible craft that was no larger than a starfighter, but was capable of unleashing destruction on a magnitude that dwarfed even the Death Star's capabilities. Unlike the Death Star, which destroyed individual planets, the Sun Crusher could destroy an entire star system by causing its target star to turn into a supernova. The key to its near invincibility was layered Quantum-crystalline armor, a material so strong that it could perfectly repel even turbolaser shots. Han Solo once was able to ram the Sun Crusher straight through the bridge of the Imperial-class Star Destroyer Hydra without taking any damage, and during the Battle of the Maw, it even survived a glancing blow from the Death Star Prototype's Superlaser, which likely would have destroyed any other ship it touched. The Sun Crusher took some engine damage from the blast, as this was its only weakness, but was able to continue to fight. The Sun Crusher was also equipped with a hyperdrive and was designed to slip unnoticed into a system, fire its weaponry, and then escape before its presence was detected.
The Sun Crusher's primary weapon was a payload of 11 energy resonance torpedoes. Each torpedo resembled an oval-shaped plasma discharge and was activated when it passed through the Sun Crusher's resonance torpedo launcher. The resonance torpedo then traveled to the system's sun at near-lightspeed velocity.
