During the First Interstellar War, negotiations were made between the Novus Initium Republic and the United Vitam State to study and examine each other’s military technology, namely the idea of developing electromagnetic or EM warheads by the Republic and using shield boosters and laser weapons on State ships. However, while the EM warheads and shield boosters were successfully developed and deployed, the State had a hard time trying to implement the laser weaponry due to the power supply needed for those weapons. When the Camino Star Empire entered the war on the side of the Republic and the State, the State was quick to see about negotiations of their versatile missile launchers with the EM warheads for the Empire’s less-energy consuming hybrid turrets. The two struck a deal without the Republic knowing and started to develop ships, namely destroyers and cruisers, with the new weapons. These ships were first deployed to the Dellino System that was under Republic occupation near the end of the First Interstellar War to enforce their joint operations in the former Lykan system.
When it came time for the Camino Star Empire to look at modifying their Deimos-Class Cruisers, the change compared to the United Vitam State’s Cerberus was rather minor as the Deimos was only modifying some of the weapons. It did not need the shield booster system like the State needed as the Empire’s nanocell armor repairer system already suiting their defensive needs. Unlike the Taranis which saw only a reduction in the number of blasters to accommodate the new missile launchers, the Deimos by comparison saw a reduction in the number of both railguns and blasters for the new launchers. Among the turrets the Deimos was equipped with, the original 11 dual medium railguns for long range assaults was reduced down to 5 and the original 18 medium blaster cannons for close to medium range combat down to 6. The remaining slots as well as 6 new slots were taken up by 24 anti-cruiser and anti-battlecruiser missile launchers. This meant that two-thirds of the Deimos’ weapons were made up of missile launchers making the ship more of a missile cruiser than other Imperial ships. The missiles, unlike the ammo for the hybrid guns, take up far more room. In order to accommodate the warheads, the ammo supply on board was reduced but the Empire sees this as an acceptable exchange as it means it has more ammo to spread and resupply other ships with. The Empire converted half of its Deimos’ to the Type 2 variant a few months after the war. The reason the Empire did not convert all their Deimos Cruisers is that they don’t want too many cruisers to rely more on missiles than hybrid turrets as their main armament in a battle.
