The XDY-9 Laser Cannon, also known as the Imperial ground laser or the Heavy ground laser was a large, powerful heavy laser cannon in use during the last days of the Galactic Republic and served until several years before the fall of the Great Galactic Empire. With a barrel caliber of 19 inches (483 millimeters), it was very capable of puncturing starship shields and taking out heavy ground armor.
The Class-9 Laser Cannon, as it was commonly called, was an extremely effective ground laser placed among all high-priority Imperial planets, including it's capital of Earth and it's factory worlds of Tronski and Alderona. Most particularly on Earth, there were over 400 of these weapons across the planet, in an attempt to destroy any atmospheric enemy warships attempting to take over the capital.
