vertical slots on the Ikazuchis: What are they?

[Bamse]

Most Ikazuchis are shown with four vertical slots between the nose and the foremost hangar bunker. Any proof of what these are?
My newest pet theory is that they're about the right size for Horizon bunkers and could even have the right spacing for a Horizon to dock both its bunkers which are then taken mechanically into the bowels of the Ikazuchi.
Thoughts?

[ShadowLogan]

I don't think there is any proof on what they are. Most likely they are some type of "door" or "hatch" for the other mecha/craft the Ik is supposed to carry can use to deploy from (though personally I think the side launch approach favored by the Ik is a poor choice for aerospace craft, good for ground forces, but poor for aerospace forces)

I do not think they are properly positioned for Horizon bunker use. They are too close together, and the wrong shape (Ik details are clearly rectangles, the Horizon-T bunkers are more squarish).

[Bamse]

I meant that the Horizon would land vertically on the side of the Ikazuchi. The Horizon bunker is, what, 8x30-ish meters, the rectangles aren't that disproportionate. They aren't a bad fit when comparing them to the size of the Alpha bunkers either. They could be too close together though. They need to be a Beta apart after all

Just surface detail, I'm afraid... the size on the original design was too small for mecha, which I suppose would make it halfway likely they were docking ports for when the ship was resupplying in Mars orbit or on the moon.

They could be hatches for allowing for rapid on/off loading of supplies?

They could be sensor panels of some sort

They could be 'go faster stripes'

They could be a hatch for a landing bay of some sort (not even necessarily for mecha but for, example, for some sort of hypothetical shuttle craft/pinnace)
