Considering that this is technically an OC ship, I've decided to compile the author notes into a description for what Epsi is equipped with, or at least is designed to be equipped with. I'm not a huge nerd for the navies so I can't be sure that this is reasonable, but I passed it through several people who are more into military technology than I am so it should be at least reasonable- ish. For the sake of reference, she is slightly larger than the current British carriers.
I also added notes on her expected performance as she might seem a bit overpowered for a world full of WW2 era ghost boats from numbers alone. Once again, it is not supposed to be a stomp fic. You can guesstimate how she should perform in the narrative from this.
You can consider the general performance of her gear to be vaguely comparable to IRL analogues of similar systems as it won't be reasonable to use raw numbers from the game. To paraphrase a comment that I've read about the CC2 carrier:
"We have a 6 shot tomahawk box launcher, an Oto Melara 76, a pair of Rapier launchers instead of something sane, four Phalanx mounts on the bow and stern, two sets of twin torp launchers off of a Clemson and a flare launcher strong enough to to turn night into day and skin cells into tumors. We fly fire scouts, some demented tiltrotor that does not tilt its rotors, MQ-9s and X-47B drones. We drop robot go-karts and four track tanks and also do artillery out the unclosing welldeck. Also we make 110 knots on waves tall enough to go mast down, someone hands helm a ham sandwich"

Combat operations notes:
Epsilon is built around island raiding solo or with small escorts. As such she is an "everything" ship and that causes design drawbacks which could be alleviated if the functions were split between multiple ships. Jack of all trades, master of none. The nuke plant makes her significantly heavier than optimal for LHA ships while having both landers and that many aircraft cut into capacity and optimizations for both. Azimuth thrusters allow for high precision maneuverability when docking or navigating in shallow water, but add extra unnecessary drag in most circumstances.
Near full automation is not as good as it sounds. While bots are capable of maintenance and most types of damage control, they lack the cognitive capacity to improvise to solve every issue in the most effective ways. Efficient damcon, refits and deep maintenance requires a skilled swarm robotics engineer specialist, but a single engineer can focus only on one problem at a time. The same applies to land forces and air forces, drones are capable of coordinating and engaging designated enemies autonomously but they are kinda dumb and work best with a "babysitter" operator to manage pathfinding, evasion, targeting and coordination along with direct remote operation when needed.
Fuel factory and a 3d printer farm lowers the logistics overhead, but they are not the be all and end all. Fuel factory eats energy like crazy for operation to the point where it can't run when the ship is moving at full power. The printer farm is mainly needed to provide spare parts for maintenance and damcon.
Epsilon is not an MCV or an RTS commander, she can't build boat escorts, she can't self-refit and printing replacement units has to be done in parts and is nearly unreasonably long. As such units "regenerate", but extremely slowly and each loss hurts for a long time. Kanmusu eating BS will help somewhat, but it is limited mainly to supplies and is less effective with drone replacements.
Long term efficient operation requires a network of autonomous facilities and Epsilon has the modules required to establish such bases. However, "construction pods" in the gaea mission are firmware packages that order underground facilities to start rebuilding, they can't rebuild where there was no base before. Constructing a base from scratch is a conspicuous multi- month long operation that requires enough construction materials to build a fleet as well as a stationary carrier to pipe electric power until base powerplants are online.
"All amphibious vehicles" approach allows for quick amphibious deployments, but even Bear tanks are light in comparison to modern MBTs and thus ground troops have poor performance when pushing deep inland. She also lacks a dedicated bulk interface logistics unit like LCAC making it difficult to supply large formations. Epsilon would need to abuse kanmusu physiology to disgorge land assets directly onto the island if logistics strain is too high to support.
Electromagnetic catapults allow for heavier aircrafts to launch, but light drones don't really need it when not hauling "all torpedoes" or "all heavy bombs" loads. This allows for WW2 style of carrier operations and wing sizes as drones are positioned on deck to be launched in huge air wings sequentially. However, Epsilon's drones are lighter than modern manned naval aviation and can carry proportionally less weapons. She is an enormous danger against 50+ year old designs, but an equivalent or just modern carrier would push her in 1v1 with heavier jets.
Two sets of deck guns allow for shore bombardment, but with 20km range if Epsilon is in range to use them she's likely in range to be shot at in return. They also take up deck space and the autoloaders stretch deep into the superstructure which is the space that could've been used for more storage, more aircraft or more marines. Same applies for the 76mm guns, but instead of taking up flight deck space they have awful elevation and are useful only against close surface targets.
VLS cells are positioned in the middle-back of the flight deck along the spine. They don't take up the space on the flight deck, but they stretch through the entire ship vertically and they can't easily launch when aircraft are nearby on the flight deck due to the upward facing exhaust vents. They are also a pain to reload, especially in cases of significant waves and wind.
Probably something like "Wait no that's not what I meant by giving into your trauma and becoming a twisted horror". I especially love the "I don't want to be a part of this".
