The reactors on-board each vessel produced so much power that even their point-defense ion cannons were each capable of delivering enough heat per shot to rival a 4.8 megaton bomb. Modified vessels such as the Invisible Hand included a number of turret-mounted quad turbolasers, thirty-four dual laser cannons, two capital-scale ion cannons, twelve point-defense ion cannons, and 8 proton torpedo batteries.
The surface of Providence-class ships were covered with numerous heavy weapons emplacements. The Invisible Hand was one example of a heavily modified Providence-class ship. This made it possible to easily upgrade the propulsion systems or weaponry of a given ship, as well as making it possible to convert the ships into starfighter carriers, or other variations. Providence-class ships featured modular compartments which made the vessels very easy to modify. The ships, like all Mon Calamari and Quarren designs, were designed to be capable of landing on water in case of emergencies. Rising from the stern portion of the vessel, was an elongated main communications and sensor pod. This enlarged model was billed as the "Separatist Dreadnought". These ships were said to be some of the biggest in the Separatist fleet and were capable of holding a planetary blockade almost by themselves. Some Providence-class vessels were longer, measuring 2,177.35 meters. Providence-class ships were massive, cylindrical 1,088- meter-long warships with a pointed nose that tapered towards the superstructure. The ships were operated by 600 droids, but commanded by sentient officers.
