for some reason the hull looks like KV-1

676 ‘s model.

Where is the gallery now..... OK, here are some Chinese cold-war prototype tank. 1980s, Type 80 tank with welded turret,this is one of the first Chinese welded tank turrets, as you can see i

ZTZ-99A2 I'm almost certain doesn't exist, the vast majority of Chinese experts and netizens I've asked regarding the name say it's basically doesn't exist and it's a western invention.


What I genuinely don't know is if Type-99A (as they I've heard there's a regular A and "heavy" A to make things more confusing) or if "heavy" A is actualy designated ZTZ-99B considering I've seen some credible sources that ZTZ-99B does exist to some extent.

It seems odd to have a ceramic based composite heavily angled like that. IIRC, that lowers their effectiveness and increases the chance that multiple plates will be hit, and shattered.

To be honest, I always figured it to be NERA.

Yeah, i also think that it is Chinese modern "take on" NERA concept/design. But, you never know for sure  :)

Are you referring to the Ceramic/NERA on the hull or on the turret front?


The setup on the turret front is actually hollow and mostly designed to break in sections after the first hit anyway, It's Ceramics and NERA backed by a layer of HHS behind that which  the tiles are mounted to. It's apparently very effective at breaking penetrator heads off and causing the rod to yaw, which significantly hinders it's chance to penetrate the "naked" turret armor behind it, and it's very spaced out to the point HEAT jets also are less likely to dig into the turret.


Posted this picture before but, diagram of how it looks.

To be fair, aside from Sapphire based ceramics (which was mentioned in an interview by the chief designer of the 98/99 family himself, sort of odd he'd do that *shrug*), the Type-99's armor composition is riddled with speculation and secrecy on what it's even made out entirely, how it's layed out and how thick, so I can't really say that's what it 100% relies on for it's armor scheme. Even the 3 steel/2 ceramic/composite sandwich it actually uses was only found out about recently.


One theory I've heard about said layout is that it's actually very difficult to manufacture the particular type of steel it uses past certain thicknesses (Maraging Grade 350), so using 3 thinner with 2 non steel armored layers over 2 thicker and 1 composite layer may have been needed. Don't quote me on that though.

I remember him being in a couple interview videos regarding the history of the Type-98/99 family's design, do you if he's done anymore very recently?






You can google his name "祝榆生”。


He died last year at age 96.

      The Al Khalid derived from Norinco Type 90IIM MBT. It was in the early 90s, when India started to test their Arjun MBT. Pakistanis looked for a MBT design that could be produced by herself. 
      Norinco provided their own Type 90IIM prototype, this is an MBT design which comprised many Western components, such as engine and transmission. 

      There were 4 prototypes for Al-Khalid development, namely P1, P2, P3 and P4. 
      P1 has a Chinese tank diesel engine with ZF LSG3000 transmission. 
      P2 has a British Perkins CV12 Condor diesel engine with French SESM ESM500 transmission. 
      P3 has a Ukrainian KMDB 6TD-2 2-cycle boxer engine with its own twin planetary gearbox. 
      P4 has a German MB871 engine with ZF LSG3000 transmission, similar to South Korean K1 MBT. 

      Norinco and Pakistanis planned to adopt one of the Western powerpack at first, but due to CoCom (Coordinating Committee for Export to Communist Countries) restrictions, China is under embargo, which means China would not import weapons form Western countries. Obviously P3 powerplant would be the only choice. All those descriptions on the internet about ESM500 in Al-Khalid is fatally wrong. 
      The Al-Khalid pre-production batch and production version all equipped with Ukrainian KMDB 6TD-2 powerpack.
      It is an extremely compact design, the engine laid transversely in engine room, twin planetary gearboxes connect to both left and right end. The 6TD-2 has two crankshafts: the front one drives the mechanical supercharger, while the rear one drives the gearboxes. The cooling system covering the whole engine room, the engine itself has no mechanical connection to the cooling system, and the cooling system doesn't need mechanical drive. The cooling system based on a unique principle: exhaust gas driven ejector. The exhaust gas from the engine is injected through the outlet ducting, produce a low pressure in the outlet side, that will suck in cold air from the inlet side. This principle is also used in the T-64, T-80UD and T-84, but as far as I know, Swedish Ikv 91 is the only western tank that have similar cooling principle. 
      As a result, the total length of powerpack is significantly shortened, much more shorter than the European powerpack mentioned above. This leads to a spare storage room between the fighting compartment and the engine compartment. This storage is for extra ammunition and fuel, when turret points 3 or 9 o'clock, the top cover of the storage could be opened from outside, containing 10 rounds for main gun, with projectiles on the outsides, semi-combustible charges on the inside.
      The data table from HIT also describe the ammunition capacity as 39+10, means that 22 ready rounds in the T-72 type carousel autoloader, 17 backup rounds scatter around the fighting compartment, and extra 10 rounds could be carried in the storage room. 
      The driver of Al-Khalid control the vehicle via steering wheel and an automatic gear control box. The steering wheel and gear control box send electrical signals to the computer, then computer control the hydraulic servo actuator to perform engage and disengage of brakes and clutches, making steering and gear changes, as well as adjusting the speed and torque of the engine.
      Mechanically the gearboxes are nearly the same as T-64s and T-72s, but have different side reducer unit. The KMDB side reducer unit is designed as a secondary gearbox, acting like a forward-reverse selector. When both reducers were put into reverse, the vehicle can reverse using the normal forward ranges. From 1st gear to 4th gear, all could be used as high speed reverse, and that's why KMDB said this is a 7F4R gearbox system. And if only one reducer was put into reverse, the track will be driving in opposites direction, causing the vehicle turns within its tracks, a.k.a. pivot steer or center steer. T-84 also applied this driving and steering system.  
      The advantages of Al-Khalid's powerpack is the versatility: all 3 types of MBT in the Pakistanis arsenal, T-80UD, T-84, Al-Khalid, share the same engine and gearbox.

      Fellow fish - imagine you had some money to develop the "next generation" 20-40mm" modular architecture turret.  Of course, you could talk about sensor fusion, using AI to detect threats, better / more integrated sensors... targetting linked to drones etc... But is this the way forwards. ?
      What is the SOTA 30mm turret on the market ? - more importantly, what are it's attributes ?? [ no need to name the manufacturer unless you want to] 
      Built in APS ?
      intelligent Armour ?
      Reconfigurability ?
      Self Repair ?
      We all have ideas... what would you see as a truly game changing set of characteristics ?  
      I think the T2000 looks interesting and there are some nice turrets from lower profile companies (as seen at AUSA).  
      Alternatively, we might be at the end of the roadmap - "gun + armour + sight is good enough"

      New high velocity 125mm tank gun reportedly starting testing for the Chinese military.  Not surprised that the data disappeared off the university website at all.
      Edit: 125mm/60? oO
