Artillery-type weaponry known as Magma spitters were utilized by Yuuzhan Vong ground forces as a defensive measure for protecting fixed positions.
These magma spitters launched projectiles that resembled incandescent, liquid cannonballs. A single fire-support team was typically equipped with a complement of four such launchers.
The name "magma spitter" bears a resemblance to both the magma missile and its launching platform, the rock spitter, a capital ship based weapon system potentially related to Yaret-Kor, though the connection between these devices remains uncertain.
While magma missiles are defined as long-range guided projectiles, and Star by Star implies a solid, rock-based construction, The New Jedi Order: The Unifying Force depicts them as "gouts," which is more akin to the projectiles fired by magma spitters.
