Mandalorian battery

The Mandalorian battery (cayarir in the Mando'a language), also known as the cayar cannon, was an artillery design that utilized multiple barrels (typically three, five or seven separate barrels) on a single system. Cannons of this design were used in the Mandalorian civilization's first centuries of existence. Early cayar cannons used solid metal balls as ammunition and an explosive slime-like substance as a propellant. These archaic cannons were often used as ground artillery during large-scale battles. Mandalore the Ultimate (Mand'alor te Anila) In modern times, the term "cayar cannon" referred to multi-barreled heavy laser cannons that were found on many Mandalorian warships of various alignments. The MandalMotors corporation's Keldabe-class battleships, first designed in around 400 BBY, were equipped with several four-barreled cayar cannons. Traditional ground-based cayar cannons reemerged during the Mandalorian Civil War (and the concurrent Great Clan Wars) in 60-32 BBY (or arguably 60 BBY-3 ABY), during which many warrior clans used multi-barreled cannons that chambered bullet-shaped explosive projectiles and used gunpowder as a propellant. This ground-based design became popular among mercenaries throughout the northern Outer Rim, though was phased out of use by Mandalorian militants by the early Imperial era.

In ancient times, the term "cayar cannon" referred to a specific design with specific materials and mechanisms. Over the millennia, the term came to mean any Mandalorian-made cannon (that fired either solid or plasma-based projectiles) that utilized more than two barrels.
