Prototype Hypertriton - Class Battleship

The Hypertriton - Class Battleship is a massive starship filled with incredibly advanced Hyperion Federation technologies. Initially, it was impossible to supply enough power to its huge array of broadside Annihilator Plasma Cannons, but this issue was mostly fixed simply by building ever larger antimatter annihilation cores. This turned it into the antimatter - drinking behemoth it is now. With the immense destructive power of its quark-gluon plasma cannons, it would simply be impossible to optimise it beyond a certain point as one might be getting close to violating the law of conservation of energy at that point.

The ship was optimized as much as possible mostly to reduce its antimatter consumption. As such an expensive warship, it also had to be tested a lot and so the project costed the HF a lot of energy and matter plasma. 

The first prototype of the Hypertriton had a software issue that caused it to attempt to constantly grow to an infinite size. Its nanobots would constantly build outwards if it had enough matter plasma. This was quickly scrapped for both obvious and not very obvious reasons. On the second prototype, it was found that there is not enough energy to supply all plasma cannons with power and most other prototypes from version 3 through to 7 were focused on increasing the amount of power it could make and reduce the power requirement. The Synchrotron was added on one of the more final prototypes and would take a massive amount of power to fire, so in most versions of the ship they had to turn either the quark-gluon plasma cannons or the Synchrotron off to fire.

Even to this day, its massive engines present a significant weak spot though it is well armored. The HF military continues to improve the armour of this weak spot specifically, and even in actual service ships are tested again and again both on the field and in war games.
