|| DETAILS:
Vengeance was the smallest class in the Old Federal Navy to use "A"-type turret mounts Notable on S1 and S2, ventral bow, and dorsal stern. S3 added additional mounts for increased firepower. The Vengeance-S3 had a reputation as a 'brawler' in the fleet, reasonably fast, strong armour protection, powerful shields and heavy firepower. All while being reasonably compact. As such, Vengeance-class cruisers were often used to enter 'Melee' range with opposing capital ships in a harassment tactic, while larger Endeavour-class vessels used their targeting computers to fire their main batteries from stand-off range.

Perhaps one of the most iconic ships in the fleet, the Vengeance-class Heavy Cruiser served in every major conflict in the Old Federation's history, earning itself a reputation as a reliable and powerful workhorse. Vengeance-class Heavy Cruisers proved their worth during the Radacri Wars, which ultimately lead to the Fall of the UTN in 4040 A.D. This stalwart ship of the line fought valiantly, holding the Federal Navy's lines against impossible odds. Though many ships were lost, the battle-tested class is one of the few ships to see such punishing conflict and receive updates to address any short-comings.

Along with its heavier brother the Endeavour-class Battlecruiser, these warships have gone on to serve in the militaries of Aquarian humans for millennia, seeing upgrades and enhancements to keep the ship relevant on the modern battlefield of space. The most recent development of this hull design is the VN-class Heavy Cruiser in use by the Aquarian Terran Imperial States' Navy, almost some thousand years after the original Vengeance-class hull was first laid down in Aquarius. As such, Vengeance-class is often considered, along with Endeavours, to be the most famous human space-faring warship of all time.

||Notes on Armour Plating:
The large, sloping panels typical of UTN ship design in the 2nd and 3rd millennium are the primary armoured belts. they are sloped to provide increased protection without adding to mass, and consist of a sandwich of Tritanium-composite with various alloys, and usually a depleted uranium or depleted citadrite (on later models) lattice/mesh under the external plating. The surface was coated with a reflective prism-like crystal lining to disperse laser-based weapons, while the sub-surface was a ceramic ablative, which disrupted plasma and laser beams after penetration; the heat from these weapons would melt the ablative lining and the resultant cloud of material would disrupt the beam significantly reducing damage for a short period of time.

Between the Pressure Hull and Plating, there is a Vacuum zone with a hydraulic suspension to absorb kinetic impacts and minimise shockwaves to the pressurised compartments of the warship. Adaptive Harmonic shielding systems prioritised areas of the ship not protected by strong armour belts, such as the distinctive 'conning tower'
