This is a summary of a thread over on /r/Aurora4x about a thought exercise involving a Superdreadnought and accompanying plans. Visit there for a slightly more full exposition -

https://www.reddit.com/r/aurora4x/comments/82mtu2/oberoth_class_superdreadnought_revised/A few days ago, I posted a thought exercise about creating a super dreadnought based on an

**orbital habitat** (Iranon79's idea) around 3 million tons, which could therefore be built at construction yards and which had a long maintenance life, but would be scrapped at the end of it's service life to avoid the need for large shipyards, maintenance facilities, or planetary hangars at any point. It's an absurd idea, but a few people had suggestions to make it better.

Nori-Silverrage and CNWagner pointed out that I could drop deployment time and add 10,000 colonist capacity which, paired with the orbital habitat, means I could create an

** impromptu colony anywhere capable of providing shore leave**. Big improvement.

Baconholic pointed out that technically, only one thing can fail in a 5-day increment, so once I approached 100% IFR, I could just lean-into it, and mitigate by having lots of MSP storage and lots of small parts. On a similar note, Hypervelocityvomit suggested I keep AFT to 5 digits to mitigate overflow errors.

There were some other commnity tweaks to the actual design too, which brought me to the revised

**Oberoth class Superdreadnought.** It has 150% stronger shields, 25% thicker armor, 150% more Gauss turrets, 132% more hangar space, is 4% faster (trivial, but in-universe, it's helpful to be faster than other fleet ships), is 35.7% cheaper, and 66.7% of the size, now a 2 million tons. There are 12,038 separate parts that could fail and 289,766 MSP,

**giving it many decades of service life without overhaul or maintenance. **The fighter compliment listed below is a more-than double-strength Kodiak Assault Wing -

https://www.reddit.com/r/aurora4x/comments/7xm53v/combines_kodiak_assault_wing, 32 additional breaching shuttles, plus a lot of peripheral light shuttles and scouts. Because the Oberoth herself relies on missile waves, her fighter compliment relies on a very different strategy. As massive as that compliment is, it takes up just 57% of the capacious hangars, leaving 60,100 tons available for other needs.

I didn't design any special systems for this, using just the normal Battlecruiser fleet tech from my lst big game -

https://www.reddit.com/r/aurora4x/comments/7tfqc2/un_battlecruiser_fleets_full_list_doctrine_andIn-universe, I think this might be designed in the far future after a disastrous civil war between the Navy and Capitalist Alliance on one side and the Combine/ Workers Guild on the other, splitting the U.N.'s systems and halting technological advancement. Splinter groups from both factions, isolated down long chains would fight for decades until the Invaders came and wiped out all shipyards and most of humanity and their interstellar brothers and sisters. Remnants of both factions would eventually join to create this, along with other fleet elements to wipe out the invaders once and for all! (or some such).

Anyway, here's the ship. I divided up the display a little to help see what's what.

This design is classed as a Military Vessel for maintenance purposes

Note that the Longstrike Anti-ship Missile is a bus with 2 sub-munitions that strike for 9 damage each.

Has this grown into a rational, viable design? Probably not, because goodness, who needs this much firepower in one place? Also, it relies on at least one exploit, costs an absurd amount resources, probably throws some in-game errors, is a liability, can never be refitted, and can never get an armor repair.

On the other hand, it requires no shipyard to build, requires no maintenance facilities or other upkeep costs over the course of its long life, provides its own shore leave facilities, and is formidable in combat.

But it is FUN and it's more viable than I thought it would be.
