Concrete-Filled Armor Blocks

i like to see concrete-filled armor blocks—extremely durable but too heavy for ships/mobile vehicles , making them ideal for planetary structures. These blocks would offer far higher resistance than standard armor but at the cost of mobility and versatility.




Key Features

1. Ultra-High Durability

  • 3-5x the HP of heavy armor against explosions/ballistics
  • Resists penetration (AP rounds deal reduced damage)
  • Weak to sustained energy weapons (lasers/plasma cut through slowly)

2. Weight & Limitations

  • Cannot be used on mobile grids (ships, rovers) – physics rejects them
  • additional resource cost (requires gravel, concrete , and time to "cure")
  • No conveyor/power passthrough – pure structural use




Why i like to see this?
  1. Gives Planetary Bases a Purpose – Makes them harder to raid than ships.
  2. New Defense Meta – Forces attackers to bring siege weapons (not just ship guns).
  3. Realistic Engineering – Mimics real-world bunker/military construction.

I don't see why it shouldn't be allowed on mobile grids - being prohibitively heavy is going to be enough of a drawback, and it has applications in floating grids when we get water - stick a few at the bottom of a hull to lower the centre of mass and stabilise bobbing/rolling.

Anyone crazy enough to actually use concrete as ship armour was always going to do something else equally ludicrous anyway.

I somewhat support this idea. I like the idea of having super heavy armour that discourages (but not prohibit) players from using them on spaceships - the weight should be discouragement enough. So maybe armour that is 2 as strong as heavy armour but 3xheavier,

I would prefer the armour not to be "concrete" because I like to think of light/heavy armour being some kind of advanced futuristic armour that is already as strong as armour - with the opposing weapons also being advanced enough to make the light/heavy armour seem not very effective.

I wrote about a similar idea here: https://support.keenswh.com/spaceengineers2/pc/topic/48111-gravel-concrete-idea#comment-97362

Stone/concrete filled armor blocks may be another option for very heavy armor for stationary and ground bases.


The possibility of using them on mobile objects may not be provided by game mechanics - if the weight of the blocks corresponds to a density of 4-6 tons per cubic meter, use on mobile objects may be precluded by the sheer weight of such armor

I forced myself to look into the game...

The large grid block in SE1 has a volume of 15.625 m^3 - a 2.5x2.5x2.5 m cube.

The light armoured block (cube) weighs 500 kg and has a resistance of 2500 units.

-> 32 kg/m^3, 160 units per m^3, 5 units per kilogram of mass. Its components have a volume of 75 litres (and this corresponds to a 2.5m cube welded from sheets thinner than 2mm. Elon starts smoking nervously...)

The heavy armour block weighs 3300 kg and has a resistance of 16500 units.

-> 210 kg/m^3, 1054 units per m^3, 5.02 units per kilogram of mass. Its components have a volume of 1200 liters (1.2 m^3, 76.8 liters /m^3 or else - they make up ~7% of the volume)


Assume a block of large grid filled with reinforced concrete. The density of reinforced concrete is usually calculated to be 2500kg/m^3. Reinforced concrete for fortifications up to 2800kg/m^3.

Then the block of large grid (2.5m) will weigh 39-44 tons.

Let's calculate, as above, 5 units of resistance per kilogram of weight -> 195,000-220,000 units of resistance. Probably a bit too much...

OK, let's count only 2.5 units of resistance per kilogram of weight -> 97,500-110,000 units of resistance...

-> 2500-2800kg/m>^3, 6240-7040 units per m^3
