Thats... uh... ambitious given the 'USSR 1960s' state of technology. I'd be very interested to see how you pull it off :)

The answer is something like three weeks of ANSYS and a lot of research. I would have used a supersonic wind tunnel but they’re phenomenally expensive

In further pursuit of open discussion of the development of tracked vehicles, SNVZ is proud to offer the RSD-1 Innovator intermediate range ballistic missile complex, capable of delivering a 425kg warhead to 1,800km with sub-100m CEP, or a heavier warhead to shorter ranges. 

 

Also, the tracks have gone missing. If anyone sees them, please return them.

Below is an image of the 15Zh6 Innovator ballistic missile, which should deconstruct notions of masculinity and phallic imagery via its role defending the peace-loving matriarchal society of the DPRC, and deliver rapid reeducation through either chemical, high explosive, or special warheads in under 30 minutes, with a response time of approximately five minutes from receiving a launch order to firing, from the transit mode at a pre-prepared firing position.

That’s not at all what I did! If anything, it’s more similar to a Pershing II

Yeah so for the record the final submission date got pushed back AT LEAST a week due to the forum fuckery that lost us almost two weeks' worth of site activity. It's not a big deal, but something for our competitors to know.

 

I will probably submit just a gun, and not a tank to go along with it.

Are Mg alloys AMX602 or ZAXE 1711 available for use? Or maybe WE43B and Elecktron 21 (EV31A)? I'm thinking about using some Mg to lighten my vehicle. 

 

AMX + ZAXE:

WE43:

I'm struggling a bit with the track length-to-tread ratio.

 

Stumpy has a 3.7m track contact length, and the tracks are each 63.5cm wide. Which doesn't result in a ratio anything like 1.5-2...

I'm looking forward to my post not being as lonely as it currently is.

@N-L-M another minor question: when the armour requirements talk about x degrees off centreline, my understanding is that they're not talking about the total envelope. So 90' off centreline is an attack directly perpendicular the side rather than an attack coming in at 45'.

 

Is this correct?

Yes. Off the centerline = measured from the centerline = arc is in total double this angle.

oops, inspired by DP 27, M 789 HEDP, OBUS G and the glorious 2S7, Kal corp offers a 12 round, 240mm HEAT autocannon.

(also capable of lobbing a Kleshchevina derivative:  Nuclear shell, if needed.

 

standard shell, M789 but at 240mm dia, so at 1.5x that 360mm penetration plus blast effects

enhanced ported shell Obus G but at 240mm, so at 3.5x thats 840mm penetration plus blast effects

mercury float HEAT shell, single charge at 5x, thats 1200mm penetration plus blast effects

mercury float HEAT shell, dual charge at 5x, thats 800mm precursor + main 1200mm penetration, less blast effects

 

each round is accurate to 3,000 metres, substantially superior to peers.  (tradeoff, penetration for increased accuracy)

 

barrel is mildly rifled, ala M230 LF & AMX 30's gun

 

unfortunately, each shell is just a tad over 100kg, so must be reloaded at depot via crane.  so despite onboard storage being plentiful, official capacity is limited.

      OK, praise be to Hubbard the last prophet and Tom Cruise, his true successor and all that shit that the upper party members will want to see in an official document.  You want to know Hubbard's honest truth?  This entire heavy tank development program has been one big conga line of fuckups since day one.  There's a reason that we're still out there tanking with DF-1s, and that reason is the current government of the DPRC.  Their insane commitment to Scientology has made a mockery of every attempt to maintain a stable and sensible war economy.  Until the ruling regime is liquidated and replaced with a government based on the scientific principles of Euphoric Atheism, the disasters will only compound.


      The military tribunal for tank procurement has selected Hakika si Kundi la Dudes Nyeupe (HKDN) design bureau's Object 426 "Stumpy" as the basis for the DPRC's next main battle tank.  In order to facilitate crew competence and speed the de-bugging phase on the way to IOC, the first several dozen vehicles will be sent to a special test unit.  This test unit will be kept separated from the rest of the DPRC military's logistical system and chain of command.  In order to prevent sabotage of the program by the circulation of false reports, the entire test unit and its activities will be kept secret, even from the members of the civilian government.  In order to prevent any theft of the technical secrets of the vehicles, the test unit will be given the authority to shut down all communications and transport networks in the DPRC at its sole discretion.
