I am honestly surprised that you managed to make a smaller tank than I did.

 

Especially considering that you were talking about widened E100 tracks and 60+ ton armor masses.

It does use similar tracks to Tiger 1 and weight is near to that of tiger 2. And I made a rough design for a 1000 tonne fortress..

 

However, I think anything at 100 tonnes with 60ies tech is a specialised tool and not a principal fighting vehicle. With weak air component I admit the weight would offer neat potential. But it would run into problems at navigating some of Texas' terrain and Texan tactics are not well known to me. Not sure if their combined arms would offer sufficient protection for fewer large and expensive vehicles. Maybe for another contest.

I do wonder, though, how you calculated weight in blender.

Perhaps after this we could have a private competition to see who can create the best wunderwaffle.

it has a 3d printing plugin that can calculate volume

Okay, I did the same.

That would be quite exciting.

   Few questions that judges have for 2 submissions:

@Sturgeon

  1. We would like to know about how commander sight works. It is located on other side of a turret from a commander, as i understand, which makes optics not a real option how to transfer information from sight to commander's eyes.
  2. 4 remote controlled MG location, i'm not sure where it is located exactly.
  3. Hull bottom armor and mine protection is unclear. What is thickness of a bottom hull plate?
  4. APU location - where it is?

 

@Fareastmenace

  1. Fuel tanks in sponsons - are they armored?
  2. Do we understand right - your design have no internal (inside of the hull) fuel at all?

@LoooSeR
1. It's a prism connection like a periscope. Admittedly, fairly complicated, but I really wanted to have that feature.
2. If you refer back to Mastodon they are in a similar location, but with paired up machine guns instead of single units. I didn't have time to model them.
3. Ah, it seems I forgot to add the floor to the array appendix. The belly is 0.875 inches RHA with 0.25 inches HHA stapled to it, if I recall correctly.
4. Above the transmission.

1- they are against light threat: 1.85"RHAe in the frontal portion, 1.1" RHAe in the rear portion, 0.75" RHAe on the top

 

2- not sure if sponsons are counted as in hull, as the sponsons are modeled as part of the base hull, and not just suspended outside

Anyhow, there is space in the engine compartment for (non modeled) back up tanks

   Additional questions - where is ammo ready rack located? Can you also add details to how wet ammo rack design works with mechanised loading system?

@Toxn

Few questions:

  • Are there any additional features to boost mine protection of both proposed designs?
  • Can you provide more details on design of fuel tanks around driver? 
  • Can you point out location of hull ammo racks and placement of blow out panels for them?
  • Would like to know level of protection and armor details of crew hatches.
  • Also would like to clear things out - optic on mast on Derebus is a stereo rangefinder?

  • Also would like to clear things out - optic on mast on Derebus is a stereo rangefinder?
  • There are no features planned beyond the standard sling seats, although as noted the 25mm/1" floor and the external suspension units (steel torsion bars and swing-arm axles housed in aluminium boxes) should make the vehicle very survivable against mine blasts by giving the blast energy a lot of things to deform and wreck before it hits the hull floor itself. The wrecked suspension units can then be scraped off and replaced with new ones.
  • I'll have to look at my CAD models again, but from memory the front fuel tank sits in front of the driver and then wraps around and meets with the ammunition storage boxes on either side of him.

 

Edit: I've had a look at the CAD models. The fuel tanks don't quite meet in the front, but angle in along with the hull. The driver's position is a capsule that terminates in a ~32cm wide front portion - just wide enough to fit pedals (throttle, brake) and the feet behind them (where it's slightly wider). Drivers with particularly wide feet may have to take their boots off.

 

  • The blow out panels for the hull racks can be seen in the pictures accompanying Appendix 2. They vent out to the left and right of the upper hull at an angle (forwards and upwards).
  • The crew hatches have the same protection scheme as the surrounding armour, with the driver's hatch being covered up to the line of sight of the driver's periscope by the surrounding ERA panels. They would include an internal strut/spring arrangement to counterbalance the weight and make them easy to open and close. Two small ERA panels could be used to cover up the remaining weakspot on either side of the driver's periscope, but my understanding is that small ERA panels don't provide as much effectiveness as larger ones so I'd expect them to be left off unless urban fighting is expected.
  • The tall optic on Derebus is a vertical coincidence rangefinder - instead of slicing the image horizontally it slices it vertically. The base length isn't amazing (about 1m IIRC) but the acquisition should be relatively fast and the errors small enough for the high-velocity rounds that Derebus is intended to use. As a bonus, it can still function as a gunsight in the event that one of the optics gets shot out - you simply remove the component blocking half the image from one or the other of the lenses.

Ammo ready rack is in the turret basket, opposite the gunner.

 

The loading system is only semi-mechanized, so the ammo rack safety system works exactly as it would in a manually loaded tank.

   Judges of this competition want to inform @Lord_James and @delete013that your submissions where excluded from this competition.

  • Lord James submission wasn't finished in time and it is incomplete, lacking critical data. Sorry, James, would be interesting to see results if you could finalise your design.
  • Delete submission doesn't meet requirements for submission itself.... Failure at basic reading skills. Although judges reviewed design itself and will comment on it later.

If imperial units were so indispensable, you could have said something before or throw my submission out the moment it was posted. Unless there were other plans..

1) It was said before, right in the first post.

2) Your submission was reviewed, and you wouldn't have won with this design anyway. It is insane and several elements are simply reality-bending piece of work. As i said previously, later judges will comment of this submission.

Cool your jets with the conspiratorial stuff.

 

LoooSeR is one of our most experienced and valuable posters, and provides something that every project needs in his role as a judge: terminal slavic pessimism. And he does so without fear, favour or bias.

This is a man who could look upon the face of God himself and then provide detailed commentary on elements in need of improvement. And we're damn thankful for it.

I have yet to meet a Russian that does not display irrational hatred for all German. Your esteemed colleague could well be that exception, in which case you should indeed be thankful.

What fault are you talking about?

The fault of failing to read, or ignoring, the requirements for the submissions.

 

Which is LMAO, but would be fine and everyone has days of retardation, but no... you had to whine like the little bitch you are, had to blame on the evil Russians.

Neither did I deny my error, nor have I blamed it on Russians. You failed to understand the written or feign ignorance. Which one is it?
