On my way back from shipping Plutonium from Planet Miura to Helgoland Station, I found the wrecks of two Old Rheinland Imperial Navy fighters. According to the designs and composition of the wrecks, they were precursors to the Valkyrie design used in the Nomad War, and subsequently the Wraith design used today. They have survived being stripped down to their hulls by scavengers from Newport Station, as well as the explosions caused by these scavengers.
I can only assume that these ships were designed to have a powerful hull, much more powerful than a lot of modern fighters. According to some schematics I searched up, these fighters were highly advanced at the time of their use, even using the infamous CLASS 9 weapon "JADE". However, this design clearly had flaws, as evidenced by their current wrecked state.
The hull used on these ships was made out of a highly non-flexible material, which meant that when all the panels were put on, there were still lightly armored weak points on these vessels, which the GMG exploited in their war. Therefore, I do not recommend replicating this armor for our combat vessels.
This does not mean we can't attempt to use it, though. The armor could prove to be very useful on our transport vessels, and on PROJECT: HIMMEL. Any of our non-combatant ships have a much higher chance of survival with this type of armor on. I will do more research on the Imperial line of technology, and how it has benefited the Unioners and how it could benefit us.
