Vehicle designer’s notes:
The P2250 was designed to be as heavily armored as possible, with the smallest weight and profile.  We tried to make use of the new experimental technologies and developed our own hydrostatic transmission and hydropneumatic suspension. This allowed much greater low speed mobility and some interesting arrangements. With the cannon mounted to the chassis, the autoloader became simplified and allowed a higher theoretical rate of fire and a reduction of crew to only 2. 

Mobility:
1. Link to Appendix 1- Not realized because of lack of weight value. 
 
2. Engine - Kharkov 5TD (increased to 6 cylinder), 16L, 800HP, water cooled, constant speed.
 
3. Transmission - Hydrostatic, 1 Forward, 1 Neutral and 1 Reverse, engine forward; motor and controls in the rear, is a continuously variable transmission, allow the engine to run at a constant speed with instant torque. It features hydraulic breaking and locking on top of normal friction breaks, also has a minor regenerative capabilities.
Appendix

Location of drive train components and their connections:

 
 
4.Fuel - Diesel, 1000L, sponsons, 400km, was planning to add optional fuel barrels for increased range, but scrapped because of time limit. 
 
5. Powerpack is set up as an open circuit hydraulic system, allowing it to power auxiliary equipment and other subsystems like the auto loader and suspension, or power tools.
Appendix
 
6. Suspension- Hydropneumatic (Nitrogen), 500mm suspension travel, 500mm ground clearance. The suspension is a fully adjustable in arm suspension using a slider crank design. Each arm has a built in shock absorber and can be either electronically or manually adjusted. Each unit has an overpressure valve to limit damage to the unit during very rough travel. Each unit is a bolt on unit, making replacements easy and fast.

2.     Drivers 3 vison telescopes. Commander features 360 degree coverage form the copula with a 4x sight connected to the RCWS. 
 
C.    FCS:
 
1.     FCS- Gun is rigidly mounted to the chassis. The gunner can select a firing mode to put the vehicle into precision mode.  Tracks turn to traverse the cannon, and the suspension adjusts to elevate to depress the gun. The gunners controls feeds into the suspensions control system, modifying the pressure in each individual suspension unit to accomplish the right elevation/depression. A gyroscope keeps track of the vehicles tilt and adjusts accordingly.  
The commanders station has duplicated controls and features a fully rotatable commanders copula with a range finder and 12,7mm remote operated HMG. The commander can measure the range and move the tank accordingly, giving a sort of hunter-killer system. 
 
2.     Link to Appendix 3- May be added in the future. 
 
Fightability:
 
1.     Ease of service and maintenance on the suspension units.
2.     Low maintenance transmission, hydraulic motors do not require a lot of maintenance.
3.     Reduced brake wear because of hydraulic parking break and minor regenerative breaking. 
4.     Reduced engine wear from running on a stable RPM. 
5.     It has a 200mm cannon. 
6.     Has a remote controlled weapons station, allowing the commander to avoid peaking his head out when firing on infantry.
 
Free expression zone:
The Nordic Feminist Design Division felt that there was a sever lack of special needs armored fighting vehicles which strives against our glories republics values. 
The team set out to make the most inclusive vehicle possible. The turret was quickly removed as it was seen as offensive to the crippled, gifted people of our republic.  Next was the issue with the height. The tank was too high to climb aboard for midgets little people, so a adjustable suspension was installed to allow the tank to lower itself. It was also of the highest importance that even our machines would bow to our Serene Highness. 
The gun was requested to be of at least 200mm caliber, which our lead engineer said was outrageous (our lead engineer has been REDACTED, and has been replaced by a more suiting, and diverse individual).  Our lead engineer agreed and work began to install the gun. Our female engineers noted that the ammunition was too heavy to be loaded manually for a woman, and was deemed discriminatory, so a autoloader was developed to accommodate the superior gender. 
 
As of currently our team failed to meet the deadline and has been REDACTED. 
Our team has been sent on a holiday in the North to sunbath in the north. 
 

 
A picture of our team of engineers going to work. 
 
 
All Hail Serene Highness.
 
 
 
(I will try to add the schematics tomorrow for the suspension and transmission, but it is 01:30 here, and I am taking the bus to work at 06:00. )

Vehicle designer’s notes: As chief designer of the 2250 Heavy Tank program at SNVZ, we had spent quite some time theorizing about ways to remedy the, frankly, superiority of the Cascadian "Norman" Medium Tank over current Californian vehicles. Our design needed to not only meet the Norman, but exceed it, by enough to ensure that no simple upgrades of the Cascadian design could undermine the qualitative advantage our design held. Where the Norman is, in many ways, a radically re-designed and improved T-55, SNVZ decided to take a similar approach with the far superior T-72. The result is a robust, light weight, technologically advanced, and astoundingly lethal vehicle which can be comfortably operated in all environments which it could expect to face, from the heat of the Mojave to the alpine chill of the Sierra Nevadas.

d.     Ammo stowage arrangement

The AL-type carousel-pattern automatic loader is capable of handling cartridges of 950mm overall length (technically 975 is the physical limit, but it is believed that a 950mm cartridge overall length limit allows significant room for growth while leaving some clearance inside the autoloader). It services the gun in circa 6 seconds, providing a reliable 10-round-per-minute rate of fire. It is fed by a 30-round carousel, with the cartridges arranged vertically around the turret ring. Reloading the autoloader carousel is conducted by the crew, and most of the shells are a single-person lift. Some of the more exotic types, including but not limited to 3BR1, 3BK2, 3OF1, 3OF3, and 3UBM3 are shipped separately as two pieces, and assembled during loading into the autoloader carousel due to the high projectile weight.
 
The vehicle is provided with two hull ammunition racks flanking the driver, which are not able to be loaded from in combat and are NOT capable of storing 3BK2, 3OF3, or 3UBM3. The autoloader separates the turret basket from the hull with a steel splinter-protective bulkhead of 5mm thickness and the driver is unable to maneuver those sorts of ammunition through the loading hatch. Total ammunition stowage for the main gun is 45 rounds, 30 in the autoloader and 15 in the hull storage racks.
 
e.      FCS- relevant systems, relevant sights for operating the weapon and so on. 
 
f.      Neat features. -- See Above
 
3.     Secondary weapons- 
Coaxial PKT:
Feeding from left to right with a disintegrating link belt. Mounted in the Mk.18 mount, and provided with 4000 rounds ammunition, of which 2000 is ready. Integrated into the main gun FCS.
 
 
 
 
Commander's KPVT:

 
 
The commander is provided with a 14.5x114mm KPVT heavy machine gun mounted to the cupola, with a sighting and control system for use while under armor. This is provided with 100 rounds of linked ready ammunition, and a further 400 rounds stowed in the turret basket in ammunition cans, with provision made to stow extra ammunition cans to the turret roof for quick reloads. The commander’s KPV can also be used as a manually operated anti-aircraft gun. It was chosen to provide a range overmatch against Mormon forces, as the 14.5x114mm cartridge possesses nearly twice the muzzle energy of the 12.7x99mm round, and has commensurately better long range performance. The Commander’s machine gun is provided with a 1-8x variable power periscopic optical system for use under armor, and back-up iron sights. Control is through electric motors and geared drive, and the gun can be slaved to the sight. It provides light vehicle and anti-infantry capability to 3,000m. The mount is fully stabilized and is able to be used effectively while on the move, and incorporates F50 NGVII image intensifying tubes

B.    Optics:
 
1.     Primary gunsight
The TPD-2-49 stereoscopic rangefinding sight assembly is a fully stabilized rangefinder and gunsight with day / night capabilities. Day sighting is provided by two sights, a high field of view periscopic unity sight and a 3 to 12 power variable magnification periscopic sight with illuminated reticle. Night sighting is provided by F50 image intensifying tubes mounted in both the periscopic portion of the sight assembly and in the rangefinder. (F50 is part of the Night Vision Generation II image intensifier program discussed in Appendix 3, Part D: Electro-optical Program Night Vision Generation II.) Provision is made for the replacement or augmentation of the image intensifying system with a thermal imaging system when such a system is ready. The sight is arranged so that replacement of the stereoscopic rangefinder with a laser rangefinder system is possible.
Range information from the TPD-2-49 is automatically transmitted to the 7M13 FCS and is included in the gun-follows-sight control scheme: the ballistic solution is continuously updated by the 5E1 and the gun aimed as the range is dialed in. As a result, firing can take place immediately after the correct range is found.
 
2.     
The commander’s hunter-killer cupola with TDD-3 optical complex is provided with a 1-8x variable power periscopic optical system for use under armor. Control is through electric motors and geared drive, and the 125mm gun can be slaved to the sight (commander's override). In combination with the 14.5mm KPVT machine gun, TDD-3 provides light vehicle and anti-infantry capability to 3,000m, as well as hunter-killer and slew-to-cue capabilities. The mount is fully stabilized and is able to be used effectively while on the move, and incorporates F50 NGVII image intensifying tubes for night operations.

2.     Small size and weight of vehicle increases strategic mobility. Low ground pressure and high power-to-weight ration increases tactical mobility.
3.     Larger number of crewmen and design of engine bays improves serviceability of vehicle.
4.     Smaller main gun increases number of rounds which can be stowed, eases ammunition handling.
5.     LUB missiles provide one-hit-one-kill capability against any and all likely targets. The large, modular design of the missile body allows it to be upgraded over the life of the vehicle.   
6.     The use of known automotive, suspension, gun and optical components based on the venerable T-72 design eases development time and increases reliability.
 
Additonal Features:
 
Additional and optional features are detailed further in Appendix 3. These include a smaller-diameter missile to replace the LUB missile, a 145mm low-pressure gun to replace the 85mm gun, a commander's stereoscopic rangefinder and an addon ERA package.

Fuel consumption is the ruler here. 

Well, firstly, the DF90 was never intended to replace the Leopard 1A5BE,  the purpose of the DF90 is to support infantry combat operations and, if necessary, providing an anti-tank capability.
 
Secondly, no miracle is to be expected from a medium-pressure 90 mm gun against a modern Main Battle Tank.
 
Thirdly, taking into account the additional weight, the running gear of the Piranha IIIC is push to its very limits.
 
Indeed, there was this one rumor with the loosening screws and bolts moving between the hull bottom and the anti-mine double-floor of the Piranha IIIC but as usual, it's overly exaggerated by the press.
 
Finally, I would say that budget cuts and wheels go well with each other. The Land Component believed until the last minute that they will get second-hand Dutch Leopard 2A5/A6.

Think about Duplet that is detonated by precursor of tandem HEAT and tries to destroy main charge with quasi-EFP/HEAT jet.
 
   It also apears that this gif below shows magnetic/EM field-activated ERA (magnetic sensor in ERA module)

 
   There were suggestions by NII Stali to make an "Active ERA", BTW. They suggested to launch a heavy plate into incoming projectile, which required a detonation of ERA tile before projectile (especially "fast-moving" kinetic-energy projectiles) connected with ERA block. This problem they proposed to solve with a magnetic-fuzed ERA. Also, they suggested this system to be used on lightly armored vehicles and to protect upper parts of vehicles against top-attack missiles and submunitions. Some search-type of testing was done under "Bronepoezd" R&D.
 

Chassis was made longer, 1 roller per side was added. Most of changes were in middle and rear sections of the hull.

I have just heard from Richard Ogorkiewicz's wife that he died suddenly on Sunday. As all will know, he was a brilliant writer and analyst in the field of AFVs. He was still active physically and mentally, just completing his memoirs. 
I remember all his many kindnesses, keen intelligence and his wry sense of humour. I wil miss him.

That's the TK 105 turret (same as the AMX-10RC).
 
Its 105 mm gun is fitted with an old muzzle break from the 1950s.
 
 
8 km/h through the water

With the slat and ERA mounted it actually starts looking like the scale model MHI had circa 2014:

(also many thanks to whoever it was that ignored the "don't photograph this" sign)

there is a lot of other pics, strange tank imho...
