JRS "demon" assault frigate type 1

While yes, this is only 3 stars, its because of the tagline, from a Systems point of view, it doesnt stand up well in a fight (AI V AI) because it has far more weapons than the power systems can handle. Even with the Power Auxiliary, which is far too spread out into small groups. While this mitigates the damage taken when it explodes (In fact, these groups are too small to detonate at all) considering the placement of other systems. Placing reactor and capacitor blocks too close to the nose of the ship rapidly drains the ship HP when they are destroyed, one of the test missiles from the fight impacted smack bang on the capacitor bank, taking a chunk of the HP away.

A ship this size doesnt "need" that many weapon modules, especially since you have started to mass reactor blocks near the nose, which could have been weapons and shield blocks, with the power capacitors shoved to the back of the vessel, and a more efficient Power Auxiliary can be fitted back there instead. There's no systems inside the furthest engine pods, which could be used to bulk up the very low shield capacity for its size, as its a veritable glass cannon that lacks the energy to power all its system in a fight.

I was very surprised that the nose was advanced armour a few layers thick, but that didnt translate beyond the very tip as far as I could tell.
The ship also lacks any defensive effects, passive ion/pierce/punch would improve the survivability of the ship in exchange for power (Which is already very taxed due to oversized weapon to reactor)

As for the interior, Im not overly good at Aesthetics, but you have gotten roof of 1 rooms to be the floor of the other, and it doesnt look quite right. The roof of the main central room is also rather bland, as is the floor is only the carved cinnebar, and the roof basically flat grey advanced armour. The potted shrubs/plants are good, But the entire ship interior is left/right symmetrical. For a ship with a whopping 40 beds total, a lot of the interior is rather empty. Vast, but empty. You could benefit by adding a kitchen to cook food for the crew, and there is no "Engineering" area on this ship which is odd given the size of it and its interior space. (Some of the crew rooms were missing consoles, just to let you know)

TLDR< a few pointers
-Careful not to place the weak, 25hp system blocks at the front of your ship. Any places that are to sponge damage, use shield capacitors/rechargers to reduce the damage to the HP when areas are destroyed

- Power auxiliary is best used in large banks up to 10k blocks. These generate a whopping 1.7m energy at least when active, more than enough to run the ship and its weapon on top of the base power regen

- Try to avoid making the floor of 1 room being the roof of another. This can look strange, and reduces the potential diversity in each room

- the rooms on this ship are huge, and rather empty and not overly detailed. Could have saved some space for more ship systems. Or with more "diversity" in the rooms such as engineering in back by the thrusters.
