The Radiation Cannon was a type of non-mounted cannon that fired radiation, making it an effective weapon when used against organic foes but left robotic soldiers unaffected. Useful for taking out otherwise effective defenses, such as those built by clone troopers, the Radiation Cannon was used by the Confederacy of Independent Systems—which armed specific B1 battle droids with the weapon—during the Clone Wars against the Galactic Republic.


A non-mounted model[1] of heavy weaponry[2] that was held in a soldier's hands,[1] a Radiation Cannon made use of radiation, firing it at any organic enemies to wear them down. Thus, the weapon had no adverse effects for battle droids, enabling units outfitted with the cannon to fire upon enemy defenses and slowly but surely erode away otherwise effective positions.[2]


During the Clone Wars, B1 battle droids armed with Radiation Cannons fought for the Separatist Alliance.

During the Clone Wars between the Confederacy of Independent Systems and Galactic Republic, the Confederacy armed some of its B1-series battle droids with Radiation Cannons, dubbing them "Radiation Cannon B1 Troopers." Serving in the Separatist Droid Army, B1s armed with Radiation Cannons were useful for wearing down defenses built by Republic clone troopers.[2]

During one engagement[1] between 20 BBY and 19 BBY,[3] one such B1 fought against Republic clones in a forested environment.[1] Radiation Cannon–armed B1s were also fielded in conjunction with E-5s B1 Troopers; while the Radiation Cannon B1s attacked defenses on the frontline, the droids armed with E-5s sniper rifles targeted enemies hiding behind cover.[2]

Behind the scenes[]

The miniature of the Radiation Cannon B1 Trooper was included with other B1 models in the B1 Battle Droids Upgrade Expansion.

The Radiation Cannon was first mentioned in the new Star Wars canon in an article on Fantasy Flight Games' website advertising the B1 Battle Droids Upgrade Expansion for their Star Wars: Legion tabletop game.[2] Along with other B1 models and cards, the B1 Upgrade Expansion came with a card and miniature of a Radiation Cannon B1 Trooper. Within Legion, the card is used to add one such droid, represented in-game by the miniature, into the player's party. An enemy trooper hurt by the cannon is given one poison token.[1]

Within the Star Wars Legends continuity, the cannon originated in the LucasArts video game Star Wars: Battlefront,[4] which was released on September 21, 2004,[5] It was identified as the RD-4 grenade launcher in the game's official guide, which was written by David Knight[6] and published on September 28, 2004[7] by Prima Games.[6]
