Harvester Heavy Hover Tank initial investigations and variants.
Harvester Heavy Hover Tank initial investigations and variants.

On of the many STC's not yet implemented, the harvester heavy tank possess one of the most versatile loadouts of any vehicle in its weight class. While the base pattern makes exclusive use of Gattling Impales, variants exist that mount almost all known weapons in that weight class. Even within a pattern there is a great deal of flexibility, as the weapon mounts are modular in most patterns. Typically each pattern will have a base weapon, and at least one other weapon type the mounts can support. As befitting it's loadout the harvester as a concept has a fairly broad design goal.

The simplest explanation of the harvesters purpose to enable the deployment of vehicle scale weapons in environments too dangerous for formations of lighter vehicles. This is a task the harvester fulfills admirably, with each tank bringing to bear a half dozen weapons protected by the armor of a heavy tank. However the number of weapons comes at a cost, the maximum size of the weapons the harvester can mount is sharply limited. While it can mount twice as many weapon as most vehicles in its weight class, it cannot mount ordnance weapons.

While the trade off of a single larger weapon to a number of smaller ones is somewhat complex, in general the defining advantage of a larger weapon is armor penetration and the disadvantage is lower ability to engage targets. In essence the harvester is intended to engage large masses of smaller more lightly armored foes, leveraging a qualitative advantage to overcome a quantitative disadvantage. While the base pattern is primarily only useful against infantry, a number of alternative patterns are able engage large formations of anything below their own weight class. As could be expected, most patterns capable of engaging tanks or power armor formations so are significantly more expensive than the base pattern. Some of the more notable variants are listed below.

Reaper pattern Harvester
Base loadout: 6 Heavy Neutron Repeaters.
Variance- 2-4 mounts may be swapped for Heavy Neutron cannons. 2-4 mounts may be swapped out for AA mount Neutron Repeaters Neutron cannons.

A simple upgrade to the base pattern. The Reaper harvester simply replaces the Gattling impalers with the equivalent Neutron weaponry. The base pattern was intended to essentially fulfill the same role as the standard harvester, only now able to engage heavy infantry at greater cost. However the increased ease of swapping out energy weapons of similar power draw has enabled the mounting of anti tank weapons additional cognators that now take the place of the no longer needed ammo bins can also enable the reaper to fulfill an AA role if needed. On a contemporary battlefield the reaper is a lethal counter to power armor formations and a significant threat to enemy armor, as the Heavy Neutron Repeater possess sufficient armor penetration to effectively engage most common battle tanks. Swapping out the Heavy Neutron Repeaters for heavy Neutron cannons inverts this, resulting in a devastatingly effective tank killer that remains effective against power armor formations. While the Reaper pattern is on paper devastatingly effective, further investigation is needed to determine if its worth the cost.

Windsower pattern Harvester
Base loadout: 18 missile launchers.
Variance- can swap out 1-4 of it's missile arrays for SAM batteries.

A lateral shift that double down on the design philosophy of using numerous lesser weapons the Windsower replaces the Gatling impalers with tri missile arrays. The tank uses an advanced auto loader system enabling it to easily pull from any of its multiple missile magazines, enabling it to easily swap payloads granting the tank a great deal of versatility. However this comes at a significant cost, the Windsower lacks the extreme endurance of most Harvester variants and consumes a large amount of comparatively expensive ammunition. However the increased logistical footprint and operating cost must be balanced against it's increased performance, versatility and lower cost of production. Simulations involving the use of melta missiles with a small reserve of plasma munitions show promise, enabling the vehicle to effectively engage most targets. It should be noted that the Windsower has relatively low maintenance cost when not engaging in active combat, and can be produced somewhat more cheaply than the base pattern. As such may serve well as a reserve tank, staying in mothball until a need arises.

Sunscythe pattern Harvester
Base load out: 6 Heavy Plasma cannons.
Variance- 2-4 mounts may be swapped for Heavy Multi Meltas

The Sunscythe Pattern is one of the most devastating patterns we possess. However even if some of the plasma cannons are replaced with the cheaper multi metla options it remains a shockingly expensive weapons system to deploy and maintain. The sheer cost of the tank render it totally unsuitable for use as a line tank, but this does not mean it has no possible use. Coordination with the Varangian Guard has confirmed that a Sunscythe pattern harvester posses a massive threat to astartes forces, easily able to cut down even terminator formations. Given the sheer threat posed by traitor astartes it may be prudent to maintain small numbers of Sunscythes as a dedicated counter force. Further wargaming with the Varangian Guard would of course be needed, as the expenditure needed for such a force is not one to be made lightly.

Stone Thresher pattern Harvester
Base loadout: 2 Flamestorm Cannons, 4 Heavy Multi Meltas
Variance- 1-2 of Heavy Multi Meltas may be swapped out for Heavy Neutron Repeaters or Gatling Impalers,.

A siege variant intended for both urban fighting and assaulting fortifications.The Stone thresher forsakes much of its ability to engage at long range in exchange for greater short range fire power. The base pattern is intended to use it's meltas for breaching a fortification, and then flushing out the defending infantry with it's Inferno cannons. The Stone threshers role changes dramatically with it's loadout, thus the investigation into possible applications is more cursery than most. In general it appears that the meltas be swapped out for defensive siege warfare, but left in if one expects to be assaulting fortifications.

Dark Reaper pattern Harvester
Base loadout:6 Heavy Grav Cannons
Variance: none.

By a significant margin, the dark reaper is the single most potent and expensive variant of the harvester. It is somewhat unclear if the pattern even saw use, or if it was designed purely as an intellectual exercise, as unlike the Sunscythe it lacks an option to swap in cheaper weapons. Much like the Sunscythe the Dark reaper is far too expensive to consider for wide scale use, yet remains a devastating counter to super heavy infantry. Weighting the extreme cost against the extreme power of the pattern is difficult and would require significant study. Should they be viable they are likely be limited to the most elite of tank crews. As such it is understandable that the Varangian Guard has expressed some interest in the design.

We should have asked whether the Sirens would want the services of cyberneticly enhanced Kraken in exchange for trade credit.
 
It did give us the Antetear Chapter of Chaos Marines through.

And you could argue that it was responsible for Rotbarts initial posting.

Honestly, I believe the Chaos God of Autocorruption is the patron of the Anteater Chapter.

It also seems that the God of Autocorruption has its eyes set on Rotbart. So if we ever fall, I know who it's going to be to.
 
@Durin, if a wet navy ship operating in Avernus oceans is crewed near-exclusively by Omicron-Kappa psykers, could the crew theoretically add to the power of a psychic power if they sing alongside the sanctioned psyker manifesting the power if the psyker does so via songweaving?

Are you seriously suggesting that we design sea shanty songweavings?
Because that seems like glorious on-air fodder.
 
@Durin, rather than a new piece of archeotech that we can find, this suggestion can instead be of something we already have. It could be what gives the Royal Basilisk a greater rate of fire, for example.

Maglev Autoloaders

Maglev autoloaders are an advancement in cannon loader technology. Utilising a series of powerful and precise magnetic plates, maglev autoloaders move ammunition into and out of cannons through the application of magnetic levitation. The biggest advantage this provides over manual loaders and conventional autoloaders is a much greater rate of fire versus manual loaders and conventional autoloaders. Another major advantage maglev autoloaders have is that they have few moving parts, improving reliability and crew safety while reducing maintenance costs. Finally, the fact that magnetic levitation technology is relatively cheap means that maglev autoloaders are very cost-effective pieces of technology. The greatest disadvantage of a maglev autoloader is that it has a very high energy draw, meaning it can only be used when connected to a fairly beefy power source.
 
Shiping
Shiping

The problem of shipping cargo into orbit is one humanity has wrestled with since before the rise of Imperium. With conventional shuttlecraft, the cost of shipping a ton a few miles into orbit can often cost more than shipping that ton to the other side of the world. With the sheer volume of material needing to be shipped this can create a bottleneck. The common alternative for bulk transit is space elevators and mass drivers, both of which comes with issues. Space elevators are fragile and can greatly damage a world should they be served near the anchor station, and mass drives expose cargo to sufficient stress to be limited to raw materials. The DaOT has found partial solutions to both issues.


Inertial sleds

Essentially a cargo container fitted with a number of specialized Inertial dampeners. The dampeners are heavily specialized for a bust of high output followed by a long cooldown. Enabling them to shield the contents of the sled from the acceleration of a mass driver. While the startup cost for the sleds is not insignificant, the extremely low maintenance needs mean once created they significantly reduce the cost of orbital shipping, greatly expanding the ability of ground-based industry to supplement orbital infrastructure. In addition to a cheaper way to move cargo off-world, they can also be used to quickly and cheaply ship cargo between in system infrastructure producing a noticeable saving on fuel.



Collapsable space elevator

A variant of the typical space elevator, the collapsible elevator is made from a large number of folding sections, each fitted with an anti-gravity system and explosive bolts. While the anti-gravity system is not used during normal operations, they enable the entire elevator to reduce its weight and inertia to the point where it can be quickly retracted without fatally disrupting the orbit of the orbiting anchor station. Alternatively, the station has sufficient maneuvering thrusters that if need be it can allow the severing to send it off an escape vector to safety if it appears the orbitals will not hold. As an additional benefit, should the worst happen and the elevator be served the sections can separate and engage their anti-gravity systems. In theory a section can survive re-entry in such a state in 90% of cases, however an Avernus it is unlikely that many sections could be recovered. While this side steps most of the issues with a space elevator, there is a far greater startup cost and significantly greater upkeep cost. Furthermore, each time the elevator is furled or unfurled it will incur significant cost in upkeep as the antigravity units sacrifice a great deal of their service life in order to maximize performance and ease of production.


@Durin I made another STC idea. as usual, if It needs any tinkering to made cannon I can do so.

@Durin can we trade Avernite wildlife with the other Imperial Remnant polities? It'd be neat for the Raven Guard to field Phase Tigers, for example.
Depends on the species I assume. The pyschic powers of Avernus species can start to fail when away from the planet like the Temple Cats.
On the other hand the species that we exported to other trust worlds almost certainly are tradeable.
Phase Tigers would probably be out whatever the case as we haven't domesticated them and their only 'widespread' use on Avernus is as a relatively popular familiar. However if you want to see a White Scar on a Laser Dino that is probably do able.

Nope, we got Phase Tiger riders in both the Helltroopers and Helguard.

So I'm pretty sure they're much more wide spread if not pretty domesticated.

Huh,

Preliminary Examination: Thanks in part to his experiences with the tamed Phase-Tigers of the Catachan 813th, Magos Biologis Saren was highly successful in his research into Phase-Tigers. One of his first discoveries is that some Phase-Tigers, generally those who are older and more experienced, can phase part of their body in or out of reality at a time. This makes them significantly more dangerous as it reduces the area that is vulnerable when they are attacking. He also discovered that the amount of time it takes to Phase in or out seems to decrease with age and experience while the maximum amount of time that can be spent Phased seems to increase. One of the more interesting discoveries that Saren made was that there are over a dozen different breeds of Phase-Tiger, each of which uses a sightly different form of Phasing, which means that void shields tuned to stop one breed might not stop others and that the other characteristics of Phasing seem to vary with breed. For example the Western Phase-Tiger is far more capable of partial Phaseing than other breeds, but cannot remain Phased for as long.
[*]Detailed Survey: This year, after several years of study, Magos Biologis Saren handed in his report on the Phase-Tigers. He tells you that there are five major breeds and an unknown number of less numerous breeds. The different breeds are all part of the same species and can easily interbreed leading to offspring with a mix of characteristics, several of the less common breeds are mixes of the major breeds. The most common breed is called the Common Phase-Tiger and is considered the base-line in every way, the Phase-Tigers tamed by the Phase-Tigers are members of this breed. The second breed is the Southern Phase-Tiger which is smaller then most Phase-Tigers and is capable of staying Phased for longer then any other breed but is slower to Phase in or out. Third is the Northern Phase-Tiger which is the largest breed, averaging around seven hundred kilos, and is far less visible when Phased but slightly less capable in the other aspects of Phasing . Fourth is the Eastern Phase-Tiger which is capable of Phasing far quicker then any other breed but at the expense of the amount of time it can spend Phased. The final major breed of Phase-Tiger is the Western Phase-Tiger which is more capable of partial Phasing then any other breed but otherwise has inferior Phasing capabilities. From what Magos Biologis Saren can tell each breed of Phase-Tiger Phases on a different wavelength and void shields can only be tuned to keep a single breed out at a time. However by making sure that each city has void shields tuned to keep out the type of Phase-Tiger most commonly found in the area which should reduce deaths by a significant amount.
[*]In-Depth Examination: Magos Biologis Saren's efforts to determine anything new about the Phase-Tigers Phasing were ineffective and he has come to the conclusion that he is running up against the limits of his knowledge. While his understanding of Biology and its effects his extensive Avernus lacks a similar expert in the Warp, at least among the Adeptus Mechanicus.
[*]Magos Biologis Saren's attempts to tame and breed Phase-Tigers were far more successful and he has managed to tame at least a few breeding pair of all of the major breeds. Even better he has found that the high level of intelligence that Phase-Tigers posses, by animal standards anyway, allows them to understand more complex commands then other domesticated animals. According to Magos Biologis Saren there is no reason that forming a large population of domesticated phase-Tigers would not be viable and work could begin on gathering one as soon as next year. It will take a while for this to have major effect however as it has proven to be necessary to raise a Phase-Tiger in captivity if you want to tame it and it takes three years for a Phase-Tiger to reach maturity.
Well I guess I forgot, I'm not sure where our actual military forces are listed. Theres a spreadsheet somewhere? However based on the research I guess we must.
 
Actually would be useful for us. Pity the AM would scream so loud if we tried it it'd burn out our ears. That seems like ultra-heresy to me.
 
I don't see why? As long as we'll have an STC or at least derive it from STC, and don't use it for AI, I see nothing AM would oppose to.
ITS CHANGE I DON'T LIKE CHANGE IT ISN'T NEEDED I DON'T LIKE CHANGE!!!

A flanderisation, but not entirely inaccurate thing of our conservatives at the moment, while more moderate parts of the admech would be fine with it, doing anything more than the bar minimum that doesn't have a ton of popular support and theological proof behind it is going to get them to start screaming.
 
What on earth has you guys so worried? It's just voxcasters that have instantaneous transmission travel times and potentially infinite range, plus some high-end cogitators. It's a far cry from AI.
