(dump?) Great Provinces of Yerstrov Flatlands - Current in-service Battle Tanks

#1
Been meaning to post my faction for a very, very long time. Yesterday I noticed it's been 3 years. So without further ado:

Great Provinces of Yerstrov Flatlands (GPYF)
Funded 23rd of December of 2016


A short introduction to the GPYF:
It's set in the same universe as Afjklol's Khertland and Haapz's Coldhaven. All 3 factions form an alliance called the Rotten Coalition, last I checked. The GPYF's mainland is an absolutely huge landmass, about half the size of Africa. We are directly south of Coldhaven (which, as the name implies, is very cold), and to the west of us is the tiny island of Khertland. We have next to no navy, but a very important tank force and airforce. You could call us a Russia equivalent. The government is largely populist, although I have yet to decide on details.

An introduction to tank doctrine:
In the GPYF, we have multiple main battle tanks all of which have different roles in the battlefield, and are meant to support each other. The main thing with our tanks is the emphasis on survivability. The tanks of the GPYF have a BARE minimum of 3m of HA on their fronts. There are 2 main types of tanks: The T series and the AL series.
--T tanks: They are the primary anti-armour weapon of the GPYF. Their guns fire solid APDS at the highest speed possible. Their role is to defend the breakthrough tanks against heavily armoured vehicles.
--AL tanks: These are breakthrough tanks. A characteristic of them is the nigh-imperviousness of their hulls. Until recent developments, these vehicles lacked much armor on their sides and rear, especially on turret, and had a reputation to spontaneously combust, but we've worked on solving these problems. Another characteristic is their dual HESH-firing guns, designed to attack fortifications but they do a decent job on tanks.

There are many more types of vehicles in service, including SPGs, SPAAGs, all kinds of aircraft, etc. But for the sake of simplicity, will be kept on another thread, or atleast separate from the main vehicles. Not to say they don't play an important role in our tactics.

Finally, the vehicles in question:

AL series
AL-8M
The AL-8M is a breakthrough tank. An old design which was in service for a long time, but has been modernized slightly with higher ground clearance.

Armament: 2x 500mm HESH at 288m/s (23m barrel, 0.287 inaccuracy)
Gun Cooldown: 0.42s per gun
Autoloader amount: 8 per gun
Max speed: 30m/s (governed)
Front Hull armor: Composite: Metal-4m HA-2m ERA-HA-ERA-HA
Turret armor: 3m HA on turret cheek, 1m HA sides
Intended role in the battlefield: Originally filled the same role as AL-9, however in recent times it's role has changed to a more supportive role. On a siege, it is to remain behind the primary force and provide a rain of HESH shells on the enemy fortifications. After the initial burst, the main forces charge the enemy while the AL-8Ms stay farther back, due to their tendency to explode if hit.

AL-9M1B
The AL-9M1B is an upgraded variant of the AL-9, which at the time was in testing phases. The original AL-9 never entered production, instead the AL-9M1B did. A massive change in design compared to the earlier boxy AL tanks, this vehicle's hull is 1m taller to accomodate thicker roof armor, has a round front in an attempt to ricochet shells (is otherwise a spacer for HEAT), and has a much smaller gun which in turn is much more armored all around. The AL-9 concept was simply to be impervious to anything, from any angle. Subsequent testing revealed a couple weakspots which were taken care of in AL-9M2. It was designed to replace AL-8, but now they work alongside each other. A new camouflage was also devised, painted on any new vehicle.

Armament: 2x 500mm HESH at 304m/s (28m barrel, 0.289 inaccuracy).
Gun Cooldown: 7.39s per gun
Autoloader amount: 2 per gun
Max speed: 30m/s (governed)
Front Hull armor: Composite: Metal-HA-2m air-3m HA-3m ERA-0.5m HA.
Turret armor: 5m HA on mantlet, 1m metal-1m HA sides, rear and roof.
Intended role in the battlefield: Main breakthrough vehicle, intended to take any punishment from up close.

AL-9M2
The AL-9M2 is the latest in breakthrough tanks, an upgrade of the AL-9M1B. Changes include a lenghtened hull and turret, a faster firing gun, a bigger engine, removed weakspots and a thicker rear armor.

Armament: 2x 500mm HESH at 304m/s (28m barrel, 0.289 inaccuracy).
Gun Cooldown: 7.39s per gun
Autoloader amount: 5 per gun
Max speed: 30m/s (governed)
Front Hull armor: Composite: Metal-HA-2m air-3m HA-3m ERA-0.5m HA.
Turret armor: 5m HA on mantlet, 1m metal-1m HA sides, rear and roof.
Intended role in the battlefield: Main breakthrough vehicle, intended to take any punishment from up close.

T series
T-9M1
The T-9M1 is a purely APDS-firing tank. The last in the conventional cannon tanks line. It's predecessor, the T-9, had a boxier turret and a huge Barrel Protection System (BPS for short, GPYF tech ftw) and costed more to produce. It's been replaced by the T-9M1, with a more streamlined turret based off of the T-10 and no BPS, and a new camo.

Armament: 500mm APDS at 685m/s (32m barrel, 0.195 inaccuracy)
Gun Cooldown: 0.29s
Autoloader amount: 11
Max speed: 25m/s (governed)
Hull armor: Composite: 4m HA-ERA-Metal-ERA-Metal-ERA-HA
Turret armor: 3m HA mantlet. 1m metal all around.
Intended role in the battlefield: Tank hunter, support the AL series.

T-10M1
The T-10M1 is the latest in railgun technology. While older railgun tanks have never entered production because of the lack of research, the T-10 made it into production and is the go-to tank destroyer when not even the T-9M1 can handle it. Due to it's cost, it couldn't fully replace the T-9, as such the T-9 was modernized into the T-9M1. Together with the AL-9, the T-10 is one of the newer Sixth Generation (Gen6) tanks.

Armament: 500mm APDS at 1271m/s (41m barrel, 0.054 inaccuracy)
Gun Cooldown: 0.67
Autoloader amount: 6
Max speed: 20m/s (governed)
Front Hull armor: Composite, mostly air. Around 8m of spaced armor.
Turret armor: 6m HA mantlet. 1m metal all around.
Intended role in the battlefield: Heavy tank hunter, support the AL series.

Due to update I've had to update the blueprints' control scheme, so none of the tanks above move anymore. I'll keep them just in case anyone needs pre-AI update tanks, or something.
Here are the updated version of all the tanks above:

But since that's boring, I'll now proceed to show you the latest advancements in the GPYF's armored force.

AL series

AL-8M2
The AL-8M2 is an upgrade to the AL-8M platform, with a completely redesigned turret and other minor changes. This new turret houses an improved burst fire twin cannon, with a more effective armor scheme which means it no longer combusts when hit.

AL-9M2C
The AL-9M2C is the latest improvement on the AL-9 platform. Changes include repositioning of smoke dischargers, added backup detection on turret sides and also a rangefinder on main detection packet.

___________________________________________________________________________

Now it's time I introduce another series of vehicles!..

DRD series

-- DRD self-propelled guns: All DRD series vehicles are self-propelled weaponry in one way or the other. Some are long-range artillery, some are anti-tank platforms, others, are indirect fire artillery. It doesn't matter if it's open top or not, if it has no turret then it's a DRD.

DRD-1M
The DRD-1 was originally a self-propelled anti-tank gun, with minimal armor and a huge gun. Now, it has been repurposed for urban combat, with a short, 455mm howitzer firing HESH shells. It is no longer designed to hunt armored vehicles, but it's gun still packs some punch.

[Image: attachment.php?aid=52868]


.blueprint   DRD-1M.blueprint (Size: 55.09 KB / Downloads: 13)
DRD-7
The DRD-7 is a small but capable tank destroyer. A replacement for the DRD-1. What it lacks in protection it makes up in armament, firing the largest HESH shell in use by the Great Provinces. It is built using the same hull as one of our light tanks. While old, the DRD-7 has proven itself quite capable and won't be replaced any time soon.

.blueprint   DRD-7.blueprint (Size: 70.12 KB / Downloads: 11)
DRD-10
The DRD-10 is one of the heaviest vehicles in use by the Great Provinces. A heavy self-propelled siege gun, armed with the largest cannon we could find. It's heavily armored and very capable of taking out fortifications AND heavy vehicles alike, although it is not used in the latter role unless extreme emergency. It is built on the hull of an AL-8.

[Image: attachment.php?aid=52871]

.blueprint   DRD-10.blueprint (Size: 129.34 KB / Downloads: 13)
DRD-11
The DRD-11 uses the heaviest, most powerful kinetic weapon to date fielded by us. It's classed as a super-heavy-tank destroyer, as it is often kept out of trouble (due it's high cost of manteinance) if smaller vehicles can deal with the threat in question. When an enemy vehicle is reported to be unstoppable, that's when the DRD-11 comes into play. It is capable of dealing with the heaviest armours without much trouble, when other anti-tank weapons would fail. It should only be fielded in case of extreme emergency, and never without support. A single DRD-11 loss would be catastrophic for the pride of the Great Provinces.

These are interesting looking, I've never seen ones like these. Not saying they look bad, I like them. I don't know if its for aesthetics or not but i'm sure you would be able to get much more firepower out of a single gun. I'd like to test them later and see how they do against mine.

Well the only one I tested is the AL-9M2. I did 2 tests with my 2 modern vehicles.

T110E3A40
Round 1 - A40 put one shot off and pierced through the hull, disabling it before the fight began.
Round 2 - A40 shot once and missed any vital areas. Afterwards a volley from the AL-9M2 cut the barrel of the A40 and would've finished it off if not for repair bots, but i'd count it as a win for the AL-9M2 seeing as how it didn't have any.

T110E3A19
Round 1 - Both shot and missed. Their reloads are similar though so both got their shots off again before being hit. Several volleys later and the detection on the
AL-9M2 was disabled by splash damage. It then continued to miss most shots and was destroyed by what I assume was its ammo rack being detonated.
Round 2 - Again both missed but the next volley the AL-9M2 was able to slice the barrel of the A19. Since if it were an even fight, the A19 wouldn't have repair bots and therefore I would count that as a win for the AL-9M2.

Overall this is a really good tank, at least in my opinion. Without repair bots my tanks would be doomed. I'd say the biggest thing i'd have to work on is finding a way to protect the barrel on mine. I do have a few tips but i'm by no means an expert.

1. Moving the detection farther back on the turret would protect it from fragments spawned at the hull.
2. Grouping your armor together would make the whole thing more reliable and strong as there are bonuses added to armor depending on how much armor is connected behind it. For instance grouping all of your HA at the front and having the ERA at the back would make the HA much stronger and would resist shells penetrating with brute force like the A40 did.
3. Whenever you can, it is helpful in the design process to make the dimensions of your vehicle the smallest possible to avoid being hit. A few good shots that would've resulted in the destruction of my vehicle missed simply because it went a bit over. There are many advantages to making tanks compact such as lower costs, higher density and being a smaller target, but that also means it can't equip a gun as strong as the one you have, so overall it's up to you.

Yep the 2 barrels are simply for aesthetic and stylistical reasons. I could do better without them, but I don't care much.

Wait what kind of gun is that? The hull should literally be impossible to penetrate by any non-railgun kinetic weapon (in 1 shot). If it's a railgun, then yes not much I can do about it. Interesting to know that I DO need to increase armor then.

1. Yes I am aware of that, in fact I did that on the AL-7 series (i think?) which as it turned out prevented the detection from actually seeing fowards if the tank was on a slight bump. So after literal years of testing different configurations, the best I could do is that absolutely huge mounstrosity of a detection packet.
2. The AL-9M2 is an old vehicle. It was before HEAT got nerfed massively and could no longer penetrate HA (or actually way later, I honestly have no idea, I kept building my tanks the same way for years paying little attention to minor updates like that). The ERA was simply there so HEAT wouldn't detonate the ammo (Which is designed SPECIFICALLY so an ammo detonation is NOT critical. It can keep going after an ammo detonation, so I doubt that was the cause of that kill). You should've tried out the AL9M2C instead, which adresses most of your criticism. I do admit it's kind of hard to test these vehicles at times, so thanks for that.
3. Oh don't worry, I already take that into consideration. If you've noticed my tanks are more or less completely solid bar the desgned airgaps. They literally couldn't be much smaller without sacrificing efficiency. I am a bit disappointed I can't make them smaller yes; the AL9 sacrificed a lot of it's size for a better all around protection compared to earlier AL series, it's gun is actually smaller but that's so I could encase it in full HA protection. I build tanks from the internals outwards, the actual guts of them are rarely more than 1m in height and 5m in width. Turrets are a whole different topic and I'm still not sure how to compact them while keeping their power similar.

Ok regarding the AL9M2C, it fixes most of the issues you pointed out: Its front is solid HA (as far as I remember), no ERA since the air gap at the front should take care of it nicely and is otherwise not needed and it has redundant detection on the turret sides (because I'm recluntant to remove the skyscaper detection). One thing to note about my tanks is that lore-wise, in modern tanks like the AL-9, most vehicles are to be retrofitted almost immediately to the newest version. Which means that the AL-9M2 is actually out of service lol.
Thanks for the feedback!

The A40, the tank that I said penetrated, is a dedicated tank destroyer using a railgun, meaning most of its resources went into the gun. If I recall correctly it can penetrate about 8 layers of 4 meter Heavy Armor beams, but that's as high as I can get it without increasing the volume past 2,000 or making it wildly inefficient. I think if you armored it with more than that it could be invincible to all the tanks I have and most AT weapons you might face. In fact i'm now having to put so much frontal armor on to protect against guns like these that 1/4 to 1/3 of the tank is a literal cube of Heavy Armor. There is a solution I've developed and it works so far, needing only a fraction of the space and having armor just as good. I'm waiting to see if people are still interested in FTD tanks to upload it, however.

Atleast I am interested in seeing your solution, you should post it, people do ocasionally come here even though they rarely post a reply.
