Umm, sorry about getting everyone to agree to Monday, but I wasn't sure until this morning that you'd accept entries then. So I stayed up late and finished - so here's the result from the UK.
Vickers-Nuffield Carnivore Mk.1A
Following the requirement from the Kaplurcastan government, the firms of Vickers and Nuffield jointly propose the Carnivore universal tank. Powered by a 750 hp uprated Meteor engine and utilising a stretched Cromwell hull with torsion bar suspension, the vehicle has the following statistics:
Length 7.62 metres (hull), width 3.46 metres and height 2.24 metres. At a combat weight of 42.5 tonnes it has a top speed of 45 kph. Armour is 120 mm on the turret front, 60 mm on the sides and 25 mm on the rear and top. Hull armour is 110 mm frontally, 60 mm on the sides and 30 mm on the rear, deck and belly. Frontal armour on the hull and turret is sloped for increased protection.
Crew is four, driver, gunner, loader and commander.
Where we feel the Carnivore really excels, however, is in its armament. Using the proven 3.7 inch (~94 mm) anti-aircraft gun as a baseline we have introduced a new breech suitable for vehicular use and a high-efficiency concentric recoil system. The introduction of an APDS projectile, firing a 6.7 kg 55 mm diameter tungsten penetrator at a muzzle velocity of 1580 metres per second, gives this gun an effectiveness second to none. A larger-than-normal turret gives the crew room to operate the gun in comfort.
There is a co-axial machine gun and the commander’s and/ or loader’s cupola may be fitted with another.
The diagrams below show the general layout of the Carnivore Mk.1A, and a colour illustration of the prototype model looking slightly dusty after the first gunnery trials.
The chart below that shows the relative effectiveness of the 3.7 versus the guns it is likely to face (and the 88 mm L/71 of the Tiger II). Note that absolute penetration is not shown, but the lines show the relative penetration compared to a 17pr APDS round. The 17pr has value of 1 at all ranges, and the 3.7 is just over twice as effective at 2500 metres. This chart also shows the effectiveness of APDS rounds versus APCR, since APDS has a lower velocity loss per unit range compared with APCR, so that, as well as offering an advantage in penetration at close range, the superiority of the 3.7 increases as the range opens.
Carnivore – designed to chew up the opposition!
Holy crap, that's a great origional Oli!
Zhukov_2005 & Soviet_Sniper Present:
T-110, Soviet Medium Armoured Fighting Vehicle
In response to the current crisis facing the Kaplurcastan military, SnipeZhuk Defense Alliance (Incorp) has offered its latest state-of-the-art military hardware in the T-110.
The T-110 carries the massive and powerful 100mm D-10T main gun, which is well capable of destroying anything the Kaplurcastan forces will face in their upcoming war. Ample room inside the turret allows for the storage of 50 shells, of which 30 are Armor Piercing (both AP and HEAT carried) and 20 are High Explosive. Secondary armaments include a 7.62mm coaxial MG and a 12.7mm Dshk anti-aircraft defense machine gun. The T-110 was designed for perfect versatility between anti-armour and anti-infantry combat.
The powerplant, a V44 12 cylinder 600hp engine, is powerful enough to propel the 35 ton T-110 at speeds up to 40km/h. Range is 200 miles, but two external 75 gallon fuel containers (at no extra cost) can be mounted on the hull to increase the range to 250-275 miles. The chassis is a modified T-34 chassis, strengthened to incorporate the recoil of the vehicle's main gun. Track width has been increased to 55cm so that incapacitation of the vehicle in muddy areas is eliminated.
In direct opposition to previous Soviet tank designs, a fourth crew member has been accomodated, so that the gunner and the commander are specialized positions. A 9-R tank radio is installed in each vehicle, allowing tank commanders a link to other tanks in the field, and to supporting infantry, artillery, and air power. A proper gun sight has been built into the turret, positioned on the right side of the gun.
With some current Soviet features/equipment, and some outside influence/improvement, the T-110 has been customed built for the Kaplurcastan conflict, and it will not let their military down.

("Killer" written on sides. Also, I apologize, this is the largest I could get the picture.)
Oli, your tank makes me feel about this big: <-> :lol:
Then it's already done half its job :lol: Detterence is better than fighting. If I'd thought about it I would have put the D-10T on that chart as well.
I prefer the translation of Ubi'itsa as "murderer",
Team Germany (Ricky and Roel)
Panzerkampfwagen VII Ausführung A "Jaguar"
Following the Specification received from Kaplurcastan, the German design team scoured their inventory for a suitable vehicle, with a good balance of firepower, protection and (as emphasised by the specifications) mobility. The obvious choice was the PzKpfw V Panther. However, it was felt that, judging by the quality of the opposition Kaplurcastan was facing, (which included some Panthers), an upgrade in firepower and protection was needed, without sacrificing any mobility.
Fortunately, German designers were already working on an upgraded Panther, the Panther II, with a new, smaller turret with the 88mm KwK 43 L/71 gun. Unfortunately, it was realised that this new turret was not developed enough to use immediately, so it was decided to modify an existing Panther turret. The major modification was the inclusion of the bigger gun, but other changes were also made. The turret front was given a moderate slope, and a ‘saukopf’ style mantlet was added to further increase protection. A turret bustle was added to the rear of the hull to accommodate stowage of the larger ammunition.
The basic hull used was the PzKpfw V Panther ausf F, which had increased armour protection over the previous models.
The larger gun and added armour did caused an increase in weight to this vehicle, which adversely affected its cross-country performance. To solve this, the designers decided to widen the tracks, thus lowering the ground pressure. To maintain even pressure on the track, the gaps between the interleaved road wheels were widened – this also had the advantage of largely negating the problem of clogged road wheels that dogged the Panther in action. Obviously, the wider tracks had the potential to cause problems when transporting the vehicle by rail or by specialist tank transporter lorries, so it was decided to use a system designed for the Tiger I heavy tank, and have narrower ‘transport tracks’ (essentially standard Panther tracks) which could be used when such a problem was encountered. To facilitate the changing of tracks the existing ‘canvas belt’ system* was utilised, enabling the tank crews to use the tank’s engine to change tracks, saving much time and manual labour.
[* This is a method whereby the tank is equipped with a long canvas belt (of the same dimensions as the tracks) with metal-ringed holes in spaced to engage with the drive sprocket. One end is attached to the drive sprocket, and the other to the track, the drive sprocket is engaged, and the track is dragged over the road wheels by the power of the tank engine, rather than by the muscle power of the tank crew.]
A thin side-skirt was added to protect the vulnerable hull side and road wheels from hollow-charge ammunition. Due to the increased width of the tracks it had to be extended out from the upper hull in the same manner as the side-skirts of the Tiger II.
In fact, the personnel testing this vehicle were so struck with the similarities of this vehicle to the Tiger II (same gun, comparable armour thickness, but smaller, lighter and with a better hp/ton ratio) that they informally nicknamed it the ‘Tiger III’. The nickname was officially frowned upon.
The prototype vehicle was originally referred to as the Panther III, but the senior officers were so impressed by the superiority of this new ‘medium’ tank to the existing German Tiger II heavy tank they decided that it needed a new name to reflect its enhanced abilities.
After much deliberation, and a trip to the Berliner Zoo, it was decided to name the vehicle PzKpfw VII Jaguar.

Unfortunatly, I have school today. My submission won't be untill afterwards. I'm actualy posting from school, and if they catch me i'll be booted from my current program. But i'm risking it because, you know, i'm a sneaky bastard like that.
Aren't I cool?
Crazy designs Oli, but whatever works right? :lol:
Yup, that is one heck of a gun. We expected to be the very cream of the crop in terms of penetration by using it - it was after all the most powerful AT gun ever mounted on a tank in WW2. Unfortunately there's those bloody Poms again.
By the way, Zhukov, are you certain the T34 chassis can handle a turret-mounted 100mm?
now now Roel, no influencing the judge before the verdict... :wink:
I think you mean a modified T-34 chassis. I did some looking, and found that with some improvements, the chassis could effectively carry this gun.

In response to the kaplurcastan request for a medium tank, we instantly began looking at the effect of our own medium tanks as they have gone against or fought alongside the vehicles you plan on going against.
It was decided outright to use the T20 and T23 chassis. Being outdated and from 1942, these contributed too many of the upgrades on our own M4 Mediums and were culminated into the Pershing. Armed with this knowledge, it was thought reasonable to make use of this chassis with minimal modification.
The tank was stripped of its turret. We were left with a T23 hull with HVSS suspension. We slightly widened the tracks, and found this to be adequate for going over various grades of mud. To save weight, it was decided that we would delete the hull machine gun, eliminating a potential weak spot in the armor.
It was then decided that we would use a variant of the T-29 turret. The turret of the M4A3E2 ‘Jumbo” assault tank was found to provide the kind of staying power we wanted. The low silhouette of the design guaranteed its use in a hull down position, and even on the offensive the turret was found to make a large percentage of the target area, the most likely part to be hit.
It was decided, however, that against the opposition you were expecting hull upgrades would be needed. We eliminated the only notable weakness found in the front armor. The next logical step was to thicken it. Based on battlefield reports of the various caliber cannons you expect to come in contact with, a well-sloped thickness of 80mm (like the German Panther tank) was found adequate. This was successful in stopping munitions from your more common adversaries, and also provided some means of protection against the 8.8cm of the German tanks. All other sides of the hull were given a dose of up-armoring as well, though not enough to provide protection against the higher caliber weapon systems touted by said German tanks.
To help counter this, ammunition pins are enclosed in their own armored shelves 10mm in thickness and the Wet Storage system is applied to all ammunition shelves. Fire extinguishers are placed conveniently under the seats in the turret and driver’s compartments to eliminate fires.
The T-23’s unique electric drive mechanism was kept on the tank, as this would help the vehicle keep its performance even after our planned upgrades. It worked by having the engine power an electric generator which in turn drives the two traction motors which are connected to the tank's final drives. This allows the engine to operate at its most efficient speed at all times since there is no direct connection between the engine and tracks, and also allows an infinitely variable turning radius. The Engine was upgraded to match the one found in the M4A3 medium for extra power. This was proven to give us the power we needed.
Finally, we chose to arm this tank with the successful 90mm M3 gun. This gun effectively eliminates all your expected opposition at combat ranges comparable to what they will be forced to engage this tank at. Ammunition shelves have enough room for 60 rounds specifically. Exact load-out will be negotiated upon acceptance of the design.
Oh man , oh man , oh man , this is goin to be tough , hmmm
I have to say that all the tanks are pretty much on the same level, but I have to go with the Carnivore because it has the best balance of speed,armour,armourment, well all the tank did pretty much but I had to judge speed difference of only 5 kph , compared to the other tanks some tanks only had an armour difference of 10mm , the guns were not to different from each other either.
The carnivore is overkill on speed has the armament we need , and allthough it dosen't have the thickest armour of the tanks it was enough, so Congrats Oli !
Congrats Oli! Fine tank that is, although the "Jaguar" is one beautiful feline! Nice job Roel & Ricky.
Also, I was wondering if anyone would mind sending me a picture of their tank to put on file with all the other tank data I have accumolated. Your guys designs are awesome, and I would be nice to show them to other tank enthusiasts without shifting through the forum files. (Of course I do not mean to pass them off as my own!) Mine are up for grabs too if anyone likes. Thanks.
If you 'right click' on this pictures on the forum you can save the picture to your hard drive.
Well done Oli!
What are your thoughts on the different tanks concerning criteria like cost, weight, maintanence complexity?
Congratulations! That tank is really ahead of its time
Actually, that is one of the things about this competition (no idea if it is a good or bad point!) that we are designing with hindsight - we know which directions AFV design took, we know what seems to have worked well. Therefore we can design with the lessons learnt since the war in mind.
All very interesting...
Eh, I prefer to try to keep my designs based on the general styles and such of the day. That's why I origionaly started this game as a "strictly using parts which exist" game.
Thanks guys. I don't know if Carnivore should be classed as ahead of its time as I used Cromwell as a base and a 3.7 in gun - a gun I've been a fan of for yonks. But hindsight works :lol:
Will post the requirement later on under the topic "Create a tank session 4 pre game" to run from today until Friday morning next week.
