J-1 Proton Cannon

The J-1 semi-autonomous proton cannon was a massive artillery piece used by the Separatists, capable of destroying an entire Republic Gunship in one shot, and dealt substantial damage even to the large Acclamator-class starships. These large grey cannons had four legs and a single turret, backed by a small body, reloading station and open fire control station manned by one battle droid. They were stationed on Ryloth by Wat Tambor and participated in the ensuing battle. Also they were able to dominate the majority of the Republic forces, until Obi-Wan Kenobi was able to mount one and destroy them all.
