For the IGSN, the Battle-cruiser represented the hull of decision for most tasks. The largest hull that could be built for and used by the named fleets, battle-cruisers were the “show the flag” warships of the military nobility. Ownership of this class meant that the nobility in question was a major success and could afford these hulls.
For the numbered fleets, battle-cruisers were the fleet escorts of heavier warships such as battleships and dreadnoughts, able to quickly get into position and escape from a dangerous threat as needed. Built and armored as a “battleship writ small”, the IGSN’s battle-cruisers were more resilient than their Equestrian counterparts, at the loss of some acceleration and agility. In addition, the hull was ideally suited for the mission of commerce denial and protection, a role that the IGSN named fleets practiced often for any potential war with the Kingdom of Equestria and the Changeling Omnivoracy.
Built as a “battleship writ small”, the Peregrine-class Battle-cruiser masses at 48,000 tons and 300 meters long, and is built for the commerce protection and denial role that the IGSN considers the battle-cruiser to be essential for. Armed with four 10cm buster launchers in the bow, six 8 cm buster launchers in the broadsides (in two sets of three), and six Sidewinder-class anti-ship missile launch cells with sufficient storage to fire eight salvoes of six missiles each, the Peregrine is armed to fight against lighter warships and defeat them easily, while able to run away from heavier opponents. Point defense, armor, and shields are at the standard for battlecruiser-class hulls, with slightly heavier armor than the average.
Like all IGSN warships, the Peregrine-class carries a “short” IGSM battalion, and is the largest ship that can be purchased by the military nobility for the named fleets.
A class built just after the Horizon War, the Falcon-class incorporates many of the lessons learned in the war. Massing at 51,000 tons and 310 meters long, the class mounts six 10cm buster launcher in the bow, eight 8 cm buster launchers in four groups of two, and six Sidewinder-class anti-ship missile launch cells with sufficient storage to fire eight salvoes of six missiles each. The largest changes in the class have been heavier shields, armor, and better acceleration, giving the class the ability to at least match the acceleration of the RESF Princess Luna-class fast battleship.
The Falcon-class Battle-cruiser is being purchased mostly by the numbered fleets, and it carries a “short” IGSM battalion for ground combat operations.
Eyre-class Squadron Drone Tender
At 49,000 tons and 300 meters long, the Eyre-class SDT is built to carry twenty-four Pinion-class ACVs and rapidly rearm and repair the ACVs in combat. Armed with four 10cm buster launchers in the bow, the Eyre also carries a dreadnought-class point defense array and a “short” IGSM battalion. The Eyre-class SDT is deployed with fleets, to provide ACV support when needed. Almost entirely deployed by the numbered fleets, the Eyre-class served well during the Horizon War.
Vector-class Marine Support Ship
Like the Eyre-class SDT, the Vector-class MSS is armed with only with a bow array of four 10cm buster launchers and heavy point defense. However, the ship is built and designed to carry a full IGSM battalion, including armor and support systems. The ship carries a thirty day combat supply for the ground troops, and a full array of kinetic energy weapons, ranging from anti-infantry to saturation strike weapons.
Vector-class ships are almost never seen on their own, and usually are a part of a numbered fleet’s support train.
