An' a turbolaser blasts bigger stuff, an', an' a turbolaser cannon blasts really, really big stuff. We need to make a really big gun. Like, a million kerjillion miles long." [downs a whiskey] "Ah, who'm I kiddin'? That's another thing I'm never really gonna do."

The Galaxy Gun was the galaxy's biggest gun, naturally enough. It was five times the length of a Star Destroyer and could blow up planets. The design was chosen over a giant bow and arrow, a giant catapult, and a giant penis.
It was commissioned by Palpatine, who had gone a little crazy after dying and being reincarnated into a clone body. He used it to blow up a bunch of planets that didn't really matter in the long run. Yo Mama blew up the Galaxy Gun by crashing a Super Star Destroyer into it.
