The normal carriers in the Astra series do not have the extra hanger doors, between the hanger and the first modular docking spot, so no way to easy load them.

I guess you could fly it around the back and unload that way, but not how it was designed.

I have uploaded a picture of it being used on the Astra Blade while docked in docking bay 2

It isn't useless without the Astra Blade though, right? Wouldn't it still work with the original two carriers in the Astra series?
