Forum:KB:What happened to the clone gunships after episode 3?

After the fall of the Republic in episode 3, the Clone army went through many changes. New armor, vehicles, ships, ect. But if you think about it, they couldn't just toss all the old equipment away. So what happened to it? But more directly, what happened to the Clone gunships that we all loved so much? If anyone knows, please feel free to fill in the blanks. There is a large amount of the Star Wars story that is not shown in the movies, I like many would like to know more.
