Featuring The Battle Planetoid Dahak (Empire From The Ashes/Dahak Trilogy)

[u/KarlMrax]

Dahak is the AI/Central Computer of the Fourth Imperium Utu-class Battle Planetoid Dahak. He was built 52,000 years ago and is exactly the size of the Earth's moon. Dahak, along with his normal crew of 250,000 (with enough space for 400,000), wield a frightening array of weaponry and support assets that allow him to engage not just enemy fleets, but entire civilizations.

This does cover a mix of Fourth Imperium and Empire feats, as neither one has feats in every category. Feats marked [/E] in their tag are feats from Empire ships which should be somewhat more capable than him.

Weapons Systems

---

Missiles

• [High Yield] His high yield gravitonic missiles can destroy planets and damage some stars.

• [Medium Yield/E] Medium yield warheads (anti-matter) are in the gigaton range.

• [Low Yield] Point defense missiles are in the megaton range.

• [Range/Hypermissiles] Hypermissiles (they are fired through hyperspace faster than light and exit at their target) have an effective range of at least 15 light minutes.

• [Range/speed/STL Missiles/E] STL Missiles with a velocity of .78c have an effective range of ~12 light minutes against a Dahak like target.

Energy Weapons

• [Yield]It's energy weapons are capable of killing it's own Battleships.

  • Battleships is capable of withstanding a few Achuultani antimatter warheads before being destroyed.
  • Achuultani antimatter warheads are often in the gigaton range.

• [Range] Effective range should be measured in light seconds with the maximum range being possibly as much as 10.

---

Maneuverability/Reaction time

---

• [FTL] Maximum FTL speed of 6!c or 720c

• [STL] Maximum STL speed of .524c

• [STL Acceleration/Maneuverability] Accelerates "instantly" to maximum sublight speed and turns fast enough while doing evasive maneuvers a human with enhanced reaction times views the stars as wheeling around.

  • Fun fact: If Dahak can make one revolution per second people on the outer layers of his hull will experience time ~.1% slower when compared to people in the center due to relativistic effects.

• [Reaction Time] Is said to be able to perceive the time between FTL jumps.

  • These occur every few femtoseconds.

---

Durability

---

Dahak's shields are a lot stronger than his hull.

• [Shields] Takes a gravitonic warhead to the shields which causes minor internal damage. As mentioned in the missile section some types of gravitonic warheads can destroy planets.

• [Hull/E] A different Battle Planetoid takes a ten gigaton warhead which makes a 20 kilometer chasm in it's hull.

---

Support Assets

---

Military

• Normally carries 200 sublight warships. They carry similar types of weapons to Dahak though are obviously much much weaker.

Personnel and Logistics

• Dahak can enhance humans so that they have three times better reaction time, eight times stronger, considerably more durable, enhanced senses, a life expectancy of ~5793 years and the ability to interface with Imperium technology.

• Has Orbital Industrial Units which build pretty much anything in Dahak's tech base including self replication which allows for geometric expansion of their industrial capacity as long as they have sufficient resources to support it.

  • Within two-ish years builds a total of ~560 sublight warships (while also working on other projects like a planetary shield, a core tap (big power source), orbital defense centers, additional industry and more).

Using Dahak on WhoWouldWin

---

Dahak is perfectly capable of going up against anything from individual enemy ships all the way up to entire civilizations.

The biggest thing with individual ships or fleets is that you have to find something that matches his stats. Individual ships that can't handle planet destroying hypermissiles teleporting on top of them and fleets which would get endlessly kited by his .52c combat speed need not apply. Also due to how much more durable his shields are than his hull, opponents that have ways of getting around his shields are going to be a lot more successful than those which need to batter through them.

His biggest weakness against entire civilizations is his relatively slow FTL speeds which prevents him from being everywhere at once. This forces him to choose between attacking key enemy systems and defending whatever base of operations he is using. This also lets his opponents mass forces for massive attacks/defensive efforts rather than spread their forces around to defend every key system as they would need to do against a more mobile opponent.

Dahak! I gotta say, I did not expect this series to make it to a featured character, but I'm very glad it did. It's probably worth mentioning that Dahak is autonomous and sentient in the series, book 2 spoilers, and that upon command it can floor its interior with radiation (I think) that renders him uninhabitable to organic life until decontaminated by his internal systems, which requires considerable power.

Edit: some more stuff:

• (Minor) Dahak possesses tractor beams that can be used to capture small craft at close range. Not sure if directly on him or attached to an auxiliary small craft.

• (Minor, Book 2) Dahak can produce hyper mines that will automatically attack craft traveling through hyperspace, similarly to the missiles. There's a difference between Imperium minds and Empire mines:

The Imperium's mines had entered hyper only to jump into lethal proximity to hyperships as they reentered n-space; the Empire;s mines popped into hyper, located the nearest operating hyper field, and then gave selflessly to make that hyper field even more efficient.

But only locally. A portion of the field was abruptly boosted a dozen bands higher, taking the portion of the ship with it, and even ships large enough to lose a slice of themselves and continue fighting in normal space were doomed in hyper. Its potent tides of energy rent and splintered them and swallowed their broken bones.

Even with Imperial technology, the mines were short-ranged and not very accurate in the extreme conditions of the hyper bands. Ten, even twenty were required to strike a target as small as a drive field... but [they] had deployed five million of them.

Unfortunately, I can't find how long it took to produce them. It has to be less than 2 years, probably even only a few months but it's not mentioned in the chapters where they're deployed.

• Book 2 (The Armageddon Inheritance) ending

Featured character posts are limited to less than 20 feats and if I remember right I am at 20 in this post so I couldn't include anything more.

All of that stuff you are mentioning would be going into his full RT which is not completed yet.

Ah, I see! Understandable choices, then :) I really like this universe, I'm glad to see it getting some love.
