There are many times when having an "obsolete" ship has advantages! After all, foes already underestimats us because we are women! Yet we have many fierce pilots!
Thankfully, we've managed to repair or replace many of the parts you'd procured elsewhere, fixing burned out parts, and getting these systems back online. Also we're in the process of updating your cannons to the new models, with newly modified interfaces, built new to purpose. You'll have a custom ship all your own with all these custom built parts!! Much of this work is easier because of our full yard capabilities.
Replacing the armour with modern, lighter weight, but more effective plating is under way already, as we tend to keep that in stock, since fellow sister pilots are worth more than plating, and we like to keep them alive.
Your engine, I am afraid, has run it's last however. I was up half the night hunting for the leak when I discovered cracks in the engine itself. They are small, but enough that she should not fly with this engine anymore. That it didn't explode on it's own is amazing, and I am glad you made it home safe! We have a few replacement options, and as the hulls of the Iris and similar fighters are smaller, fitting one into your ship shouldn't be difficult. Depending on if you want efficiency or sheer power, or some form of balance will decide what type of engine you prefer. Our engines are a good balance, but some of our allies offer more speed at the cost of more fuel consumption.
As for the Cheetah, if it is within your means it is a fantastic thruster, and with the extra space your ship offers in hull capacity, upgrading shouldn't be a problem.
As for your shield generator, I feel that your best best it to place it with the engine in the museum! But our newer model generators take up much less space, and offer more protection per ton. Much like armour, we keep a good stock on hand, so again, replacing it will be easy. Though what type of shield you get issued would depend on your main operating area. if you fly escort in Kusarai space most of the time, then the standard shields many of us use will work great, and is DEFINITELY an upgrade.
As always sister, feel free to reach out with questions! if I don't reply, i am probably in the shipyard somewhere working on something.....
