How do you think the multi-tons missile get pushed up high in the air? There is actually an explosion under the missile's ass

Those are stain marks left over by the cold-launch propellant. If it recall correctly, the cold-launch propellant is basically coal powder, which is ignited underneath the missile to push it clear of the silo, at which point the missile's main rocket motor ignites. So the smoke marks are from the coal powder.

I thought there was a huge rubber band underneath the missile... Jokes aside, I had no idea there was an explosion. I thought the purpose of a cold launch was to avoid explosions that might damage the ship...

It's not a explosive detonation with gaseous expansion reaching hypersonic speeds. It's a much lower pressure ignition, just enough to push the missile out. No harm done.
Yes, but giant rubber bands sounds much better.
The force of the coal gas as the bottle pops underneath may have smeared the missile in tiny fractions of a second before the missile lifts off. The speed of the gas expanding would be much faster than the initial take off speed of the missile.
That's where the CCL concept comes in. It doesn't smear the VLS since its all within the canister. You merely lift out and dispose of the fire canister.
132 Suzhou sends their Year of the Ox greetings. Oh wait, when did that ship got commissioned?
