MrVic: yeah the whole disappearing gun idea is just a great blast from the past. (no pun intended) lol love both your guys versions.
I really think some of us had more fun with the wilder ideas then the norm. Kinda of like a mini competition off the books

MrVic: Himura Nice pics wish I could get a color scheme on mine that looked good . Very nice!
Had one question you had 6990 kg listed with the armor? and 15ton total weight? figure you were breaking the armor out in weight which is nice.
Tho was curious with similar dimensions to a panzer III how you got more armor on it and shaved off 5 tons?

MrVic: I have been curious how often tanks miss a shot. Wondering how many shots usally get exchanged in a 1 vs 1 fight. Kinda confused on the sighting a enemy tank and how much computer assistance to aiming is in effect?

Jeremy Taylor: All vehicles have different reload time, turret rotation and top speed rates. World of Tanks fighting vehicles' characteristics completely correspond to their real prototypes' specs but have been increased and adjusted proportionally for action gameplay purposes.

MrVic: Churchill MK. Ic

Origins
The Churchill Mk I was a design started just after World War 1. Being originally designed for infantry support
it mainly focused on armor and the ability to cross trenches and crush obstacles. This outlook was starting to
change with the reports coming out of Poland when Germany invaded. Dr. H.E. Merritt was in charge of revisions
to the Churchill. He made a number of changes to the concept and design, one of these was the Churchill Mk. Ic.
With the need for a true tank hunter to use against the coming German offensive was going to be in great demand.
The problem with this was due to how narrow the chassis was, mounting a larger anti tank gun in the turret was not
an option. He had to think of a new way to get more space above the chassis. He settled on a angular reinforced
box almost resemebling a bunker. With heavy armor and the room to store more rounds of ammunition, combined with
the capability to mount a larger main gun he had his revision well on its way. While searching for a suitable main
gun he added a few revisions adding track guards and replacing the engine with a higher horsepower engine for added
speed. Finally he settled on the 3.7-Inch QF which was modified for his needs easily. The 3.7in QF would prove to be
a formidable weapon in the coming months. With this improvements in place he built the first 10 for testing.
The last stage of testing was to come in the form of german panzers cresting the horizon and then the production
order would be in great demand but time will tell.

MrVic: might have some intake/exhaust issues blocking some sight. but you could reroute the exhaust out the rear of the tank. That could be fixed a description really. gun position could be bit scary when on incline and firing but you may be okay. Other wise would work

MrVic: US/UK M90-C
Nicknamed “Colossus”

Origins
Dieter Hartmut was the mastermind behind the M90-C. Born in 1901 and having lived through WW1 he had a
grim outlook on the world. In his childhood he was home schooled by his father. Being
that his father was an engineer tasked with developing weapons of war for Germany. He had little time for his son
in childhood years. As Dieter got older his father would take him to work with him and continued to teach his
some the family business so to speak. In Feb 1936 his father ran afoul of the Gestapo. Details never came
out but Dieter returned home from work to his mother and father dead in his family home. Dieter left Germany that
night, fleeing for Britain.
Upon arriving in Britain with the brewing of possible war Britain refused him asylum. Weighing his options he
decided the farther he got from conflict the better. Dieter left for the U.S. the following day. After he arrived in the
U.S. he sought out the only work he knew, mechanical engineering. He quickly caught the eye of the Dept of Defense
mainly due to being a German refugee of sorts and his background with German military designs and technology. They
approached him with an offer to work for the Government. Dieter accepted and began laying out everything he had worked
on leading up to the day he fled Germany. He was part of a engineering group exploring heavy armored vehicles and tank development.
With his rough sketches of what he had worked on being combed over by the Dept of Defense they struck upon an offer, help the U.S.
develop weapons to combat the Germans if things boil over in Europe and threaten the U.S. He agreed as long as he was permitted to
build as he saw fit. They agreed and he began work with a small group of engineers on what would become the M90-C.
Dieters design moved quickly at first, the rough work had been done before he left Germany. He had always thought
if you make a weapon seem indestructible and it have the capability destroy all that stands before it. Then you not
only have a the strength to win any fight, but a immensely powerful psychological weapon. Fear would be his tanks
greatest armor of all. With heavy armor protection. He had designed a 82 ton Heavy Tank that could withstand an
immense amount of enemy fire. With side armor skirting, thick skinned, and dual road wheels he thought he had all
the protection the M90-C would ever need.
Mobility was going to be his greatest hurdle. Not only speed and turning but turret rotation and elevation needed to
be addressed. He realized the only way to efficiently move a beast of this size was hydraulics. Dietier designed a
simple control scheme for turret operations but he had yet to find a power plant capable of bringing his tank to life.
After approaching many manufactures about engines they had developed he stumbled upon Ford’s V8 GAA. While the engine
was being primed for use in the M4 Sherman designs currently, he thought he had found what he was after. In the end he
met with disappointment as it was underpowered for his needs. Before leaving he was shown designs for the V12 GAA that
was the original design of the V8 GAA. Ford had designed the V12 version for aircraft engines in hopes of supplying it
to the navy for aircraft, but the production contract was given to Allison’s 1710 cid V12. So with aircraft moving towards
radial engines ford cut 4 cylinders off their original design and redesigned if for use in tanks most notably the Sherman.
Ford’s loss became Dieters miracle, with the production line and tooling in place to produce the V12 GAA he persuaded them
to run some with hopes of giving them a larger contract for the engines once his design was accepted. Dieter now had the
power he needed. Being aircraft engines designed as light as weight as possible it would work out nicely. He decided upon
using two engines for the extra power to spare. This also enabled some redundancy incase one engine failed or was lost.
The second engine could power the tank tho at a reduced capacity. By designing each engine into separate compartments with
two isolated fuel tanks he gained a lot of durability as well. The horsepower gave the M90-C a rather fast turret rotation
speed of 17sec even with the immense weight of the turret.
The final stage of his design was armaments. He easily adapted the Browning .30 cal to a coaxial and hull mounted
machine gun positions for infantry defense and added an option Browning .50cal on the turret to be used as anti-air or infantry defense.
Dieter then focused on the main gun, trying to find something in line with the early designs of the high velocity German gun
that were being worked produced at the design level when he fled Germany. He quickly found what he was after in the
90mm M3 Anti-Aircraft gun. With a minor redesign of the powder charge of the standard round and reinforcing the barrel with
stronger and higher heat resistance metals, he had his weapon. The 90mm A2 “Super”. With the added power he could achieve a 1012m/s muzzle
velocity with the 90mm M3 HE/AP round.
Dieters design was accepted though with a small testing production order. International took the contract and produced 15 standard
models to be tested prior to final approval. The M90-C performed well in the series of review tests, even though a unforeseen hydraulic issue
in the secondary engine was found mid testing. The M90-C still finished the test that day due to the redundancy Dieter had designed.
A few minor changes were made and the Defense Dept accepted it but with a limited production run only. As many were skeptical of
the material cost and usage of such a weapon, they decided to wait and see if this would or would not be the weapon they needed.
The first true combat occurred in May 1940, two prototypes were rushed to Europe after Poland was invaded, with the hopes of a good performance test.
Germany soon turned towards France. The 2 prototypes only arrived in time for the defense of Dunkirk. Both M90-C’s took a heavy toll on the German
forces before being overwhelmed. One was lost to the crew abandoning the tank and detonating the remaining ordnance. The
other was presumed captured or loss no one was sure. Though Germany later produced tanks of a similar weight class and concepts, it was never proven
if the captured tank was the reason or if they had followed through on their own designs. When the U.S. entered the war and the M90-C
being combat proven now, the orders and production had greatly increased. The fear of the mighty M90-C was unquestionable to the
enemies who were foolish enough to stand their ground in the face of such a beast!

Designer notes:
Started out with a basic heavy tank that utilized some of the favorite ideas in a lot of WW2 tank designs. The main thing I wanted to strive for was a
heavy tank capable of fast turret rotation. Also I wanted to dabble with a Allied tank and finding a power plant to support such a tank I knew was going to
be the hard part. Reading about I ran into the V12 that I never knew existed let alone was ready for production to start any day when it was abandoned.
With light weight and reasonable size I was set. more to come...

Designer notes:
Started out with a basic heavy tank that utilized some of the favorite ideas in a lot of WW2 tank designs.  The main thing I wanted to strive for was a
heavy tank capable of fast turret rotation. Also I wanted to dabble with a Allied tank and finding a power plant to support such a tank I knew was going to
be the hard part.  Reading about I ran into the V12 that I never knew existed let alone was ready for production to start any day when it was abandoned.
With light weight and reasonable size I was set.    more to come...

MrVic: US/UK  M90-C  

Nicknamed “Colossus”



Origins

     Dieter Hartmut was the mastermind behind the M90-C.  Born in 1901 and having lived through WW1 he had a
grim outlook on the world.   In his childhood he was home schooled by his father.  Being
that his father was an engineer tasked with developing weapons of war for Germany. He had little time for his son
in childhood years.  As Dieter got older his father would take him to work with him and continued to teach his
some the family business so to speak.  In Feb 1936 his father ran afoul of the Gestapo.  Details never came
out but Dieter returned home from work to his mother and father dead in his family home.  Dieter left Germany that
night, fleeing for Britain.

   Upon arriving in Britain with the brewing of possible war Britain refused him asylum. Weighing his options he
decided the farther he got from conflict the better. Dieter left for the U.S. the following day. After he arrived in the
U.S. he sought out the only work he knew, mechanical engineering. He quickly caught the eye of the Dept of Defense
mainly due to being a German refugee of sorts and his background with German military designs and technology. They
approached him with an offer to work for the Government. Dieter accepted and began laying out everything he had worked
on leading up to the day he fled Germany.  He was part of a engineering group exploring heavy armored vehicles and tank development.
With his rough sketches of what he had worked on being combed over by the Dept of Defense they struck upon an offer, help the U.S.
develop weapons to combat the Germans if things boil over in Europe and threaten the U.S. He agreed as long as he was permitted to
build as he saw fit. They agreed and he began work with a small group of engineers on what would become the M90-C.
  
    Dieters design moved quickly at first, the rough work had been done before he left Germany.  He had always thought
if you make a weapon seem indestructible and it have the capability destroy all that stands before it. Then you not
only have a the strength to win any fight, but a immensely powerful psychological weapon.  Fear would be his tanks
greatest armor of all. With heavy armor protection.  He had designed a 82 ton Heavy Tank that could withstand an
immense amount of enemy fire.  With side armor skirting, thick skinned, and dual road wheels he thought he had all
the protection the M90-C would ever need.  

    Mobility was going to be his greatest hurdle. Not only speed and turning but turret rotation and elevation needed to
be addressed.  He realized the only way to efficiently move a beast of this size was hydraulics.  Dietier designed a
simple control scheme for turret operations but he had yet to find a power plant capable of bringing his tank to life.
After approaching many manufactures about engines they had developed he stumbled upon Ford’s  V8 GAA. While the engine
was being primed for use in the M4 Sherman designs currently, he thought he had found what he was after.  In the end he
met with disappointment as it was underpowered for his needs.  Before leaving he was shown designs for the V12 GAA that
was the original design of the V8 GAA. Ford had designed the V12 version for aircraft engines in hopes of supplying it
to the navy for aircraft, but the production contract was given to Allison’s 1710 cid V12. So with aircraft moving towards
radial engines ford cut 4 cylinders off their original design and redesigned if for use in tanks most notably the Sherman.
Ford’s loss became Dieters miracle, with the production line and tooling in place to produce the V12 GAA he persuaded them
to run some with hopes of giving them a larger contract for the engines once his design was accepted.  Dieter now had the
power he needed. Being aircraft engines designed as light as weight as possible it would work out nicely.  He decided upon
using two engines for the extra power to spare. This also enabled some redundancy incase one engine failed or was lost.
The second engine could power the tank tho at a reduced capacity. By designing each engine into separate compartments with
two isolated fuel tanks he gained a lot of durability as well. The horsepower gave the M90-C a rather fast turret rotation
speed of 17sec even with the immense weight of the turret.

   The final stage of his design was armaments. He easily adapted the Browning .30 cal to a coaxial and hull mounted
machine gun positions for infantry defense and added an option Browning .50cal on the turret to be used as anti-air or infantry defense.
Dieter then focused on the main gun, trying to find something in line with the early designs of the high velocity German gun
that were being worked produced at the design level when he fled Germany. He quickly found what he was after in the
90mm M3 Anti-Aircraft gun.  With a minor redesign of the powder charge of the standard round and reinforcing the barrel with
stronger and higher heat resistance metals, he had his weapon. The 90mm A2 “Super”. With the added power he could achieve a 1012m/s muzzle
velocity with the 90mm M3 HE/AP round.

    Dieters design was accepted though with a small testing production order. International took the contract and produced 15 standard
models to be tested prior to final approval.  The M90-C performed well in the series of review tests, even though a unforeseen hydraulic issue
in the secondary engine was found mid testing. The M90-C still finished the test that day due to the redundancy Dieter had designed.
A few minor changes were made and the Defense Dept accepted it but with a limited production run only.  As many were skeptical of
the material cost and usage of such a weapon, they decided to wait and see if this would or would not be the weapon they needed.
The first true combat occurred in May 1940, two prototypes were rushed to Europe after Poland was invaded, with the hopes of a good performance test.
Germany soon turned towards France. The 2 prototypes only arrived in time for the defense of Dunkirk.  Both M90-C’s took a heavy toll on the German
forces before being overwhelmed. One was lost to the crew abandoning the tank and detonating the remaining ordnance. The
other was presumed captured or loss no one was sure. Though Germany later produced tanks of a similar weight class and concepts, it was never proven
if the captured tank was the reason or if they had followed through on their own designs. When the U.S. entered the war and the M90-C
being combat proven now, the orders and production had greatly increased. The fear of the mighty M90-C was unquestionable to the
enemies who were foolish enough to stand their ground in the face of such a beast!

MrVic: There are some but do to the basics of armor size and protection they all kinda resemble something a lot of times Like the hetzer anything with step angles on all sides ends up much like a hetzer heh. I do have a few that are pretty much customs tho their hard to tell which ones I bet.

MrVic: Rereading the orginal post and comment about die hard simulator freaks.... I had this scary thought of Wii motion controls and a cinder block you have to lift to reload your tank... made me chuckle Yeahhh lets not go there

Jeremy Taylor: Players will be allowed to make their own drawings. Obviously, players will have to follow the certain rules when creating their personal custom items.

MrVic: I figure with cross chatter amonst team mates any tanks we don't know alot about or weaknesses/strenghts we will get more info out of some trial and error and cross talk on our teams. Since working as a team is one goal, I think that alone will help massively. In most the lower teirs of the trees tank styles usally share a similiar look so that will help a ton. Russian Germany British and US all had pretty diverse look starting out. Even so later on. Now modern tanks can be hard to tell apart these days for sure

MrVic: cool drawing lordlothair
One the hardest things to watch out for is tank width. WW2 Europe roads were narrow cities even more so. That combined with dificutly trasporting on railroads and clearing tunnels is really hard. More modern tanks like the leopard 2, challenger, abrams all use a large chassis. Those tanks would have great issue in WW2 in just travel. Moving up a road they would block the whole road in most cases really screwing up the flow of supplies and logistics. This has created a big challenge for us.
side note:
WMD saw you mention 1944 tech, figure you know we were based off 1940 tech (makes it a good challenge) just didn't want anyone to get confused and create a disqualified submission in these last few days
pretty much takes most anything above a pak 40 and the 17pdr is out also this early in the war as it seems it was not even in concept till after 1940. which creates some fun design challenges.
Hope to see a lot more tanks towards the end. Figure they will be great since the framework is kinda set in place now!

Jeremy Taylor: Players will not be able to ruin all buildings into splinters. Still, in World of Tanks each building will include destructible elements that players can demolish at their own leisure. At the moment, village buildings are completely destructible.

Jeremy Taylor: World of Tanks is not purely a simulator, though it has some simulator traits. We are developing an action tank game. We can assure you that World of Tanks will provide tons of fun both to casual action-game lovers and hardcore tank buffs. The game is very friendly to newcomers and players learn all the World of Tanks fighting vehicles pretty fast. Moreover, closer to the release date we will publish the Tank Encyclopedia that will contain all the vehicles' detailed specs.
There's no need to be a history nut or tank building geek to join the community (though such types of players are also very welcome) and have fun from playing. You are more than welcome on this forum.

MrVic: Yeah basically it was in its infancy pretty much most of the war. Like all things they were a bit crude due to its "new". There are conflict reports on what styles they had actually used even.
Its pretty well proven they used search light infrared where basically you shined a light that is invisible to the human eye and anything it hits is "illuminated" in the infrared spectrum. Think highlighter with a spot light. Then the driver/gunner not always both had a diode tube they looked through and through the scope which would take the highlighted objects and make them show up in a crude fashion. This makes it hard since if your the person looking through the scope is not where the spotlight is aimed its not really functional.
Another version not really confirmed and many think is fake and embellished was the direct scope sight line. forget all the details but it was more in line with modern usages and highly unlikely due to the power of the scopes/diodes they had at that time. Still its pretty amazing they advanced so far so fast and in a limited form were actually employed in the field.
Been a few years since I have really brushed up on the tech.

MrVic: A German company began working with it in 1935ish, and I think and the German army had some working it in to the army in 1939 tho none was implemented till 1945 area. Something like 40-50 German tanks were equipped with it later in the war, I think mostly panthers. But with its being such a new tech and the first muzzle flash caused it to "sunburst" for a bit which was a more distorted image. Its imaging was no where near what it is today more of a blob on the horizon. It worked to see if something was out there, hitting a target and using it after a large amount of shots tended to make them dead weight. Plus the first thing most forces did on the lines was fire off a flare which was bad for the infrared of that time period usually. I have read numerous places they fine tuned the sudden thermal heat source emissions not overloading the viewing diodes, tho not really sure how much success they had. The biggest thing that made them very useful was the true first generation of "image intensifiers" which did not arrive untilthe Vietnam war. Kinda of a toss up on powering/maint ect vs use.

MrVic: Nice post
always tempted to put the infrared on a tank but due to bad resolution skipped it. That and once the first shot was fired it would sun burst blank usually.
Tho would help with early warning some
