C-Railgun turrets on the Ymir for anti-air protection? The big hull probably has the room. Material cost is not a concern here, just complexity.
If it didn't feel a bit too nuke like, I would repost the HADES for this contest. as is it feels a little too much like making a nuke.
The Odysseus is a small craft, compared to the Orleans and the Gandiva. Measuring in at 5 meters long, the small witdh of the body compared to its length make the Odysseus look very similar to a crossbow bolt, down to even the small fletching like wings it posses and a deadly "tip"
The Odysseus is built to be the fastest and most maneuverable flyer in the sky, with a long crossbow bolt like body with their Fletching like wings located at the back third and stretching all the way to the tail.
These three fletching-like wings are designed with alighted cealium at their edges, like the system that pushes the Caliburn forward. When all three are activated, the craft moves forward at incredible speeds, approaching 152km/H or terminal velocities as our scientist know it. This should make the Odysseus 20km/H faster than the Charybdis.
By deactivated or activating the Aligned cealuim located at the butt of the craft and the tips of the wings, the pilot can turn the Odysseus, making it damn near dance through the sky.
Located at the tip of the ship is the only weapon it possesses, a 40mm automatic cannon that has been wrapped in K-wool to prevent its firing from tearing apart the ship from backlash due to its small frame. The shells of this 40mm autocannon have been modified to better preirce hard armor, via a tip made of tungsten cardide, with a much higher shock capacity than regular steel, as well as a steel jacket.
The Odysseus speed and maneuverability gifts it all the time in the world to line up the perfect shot on its target, at which point it will be child's play to take down the enemy while avoiding retaliation.
While it is capable of making attack runs on ground targets via diving, the Odysseus has one purpose. To hunt down and tear the charybiduous from the sky, dodging any return fire while tailing the ship before initiating a killing blow.
to facilitate this, an Orleans has been stripped off its gorgon, Making room for a pair of launchers for the Odysseus. These launchers, are basically a set of metal rail that the Odysseus wings and main body slot into.
When launching, the Odysseus pushing itself along these railing, launching from the ship. Orleans crewman keeps the rails covered and cleaned in between launches.
When the Odysseus is required to slow down to land, it will cut power to its Gravity propulsion, slowing itself down. Then, If that doesn't slow it down fast enough, the odyssues will deploy 6 small panels around the body of the ship. These panels contain aligned calcium pointing in the opposite direction of the nose of the ship, and when activated create a steady but weak gravity field that will help to slow the ship down, like a car brake.
Of course, the Odysseus eats A LOT of power and will burn through its magazine relatively quickly in a dogfight, even with the best shots possible. As such, the Odysseus has been designed to land on a Mother Orleans, carefully guiding itself back into the launcher mechanisms much wider receiving end with ease. During which the crew of the Orleans will replace the promethium rods, refill ammunition and other small maintenance issues.
These Mother Orleans are more convenient compared to a Landing strip due to their ability to match a frontline, But will still be some distance away from the front, never growing to close.
In the event of a Charybdis raid, it is estimated that they would need to combat both ships that are in progress of leaving the carriers, guarding the carriers and returning to the carriers. A proverbial kicking of the hornet's nest.
