The B-type mobile shipyard facility is one of the Nivenian Empire's largest mobile ships designed for military use. However, the B-type Mobile Shipyard Facility is not designed for direct combat, but rather indirect combat and a support role characterized by the manufacturing of military spaceships in the field. This allows the Nivenian Empire's Navy to be relatively self-sufficient and make new ships during protracted interstellar warfare - a necessity in order utilize power effectively at distances that require years to get to.

While the ship is almost invulnerable to both plasma weapons and kinetics, it is weak against lasers and electron beans. As the B-type mobile shipyard is typically employed outside of the battlefield, it is typically attacked by the actual navy of the enemy, and only when the battle has been lost and the industrial equipment is being targeted to prevent more ships from being produced. These ships are difficult to take out, as both plasma and kinetic weapons (the most developed types in the Nivenian Empire) are useless against them, especially with good point-defense support. What they are vulnerable against, however, are large, slow-moving, maneuverable missiles with extremely high yields, enough to knock out the crew with high g-forces.
