    Your ability to design a fantastic three dimensional shape, and then unfold it into a flat sheet, is really impressive.

    Hi! Thanks for the comment and asking.
    The first time I knew the fact that a gun can fire in the vacuum space was when I was a 12 years old. My father told me that NASA provided a simple question to the public that what items do you choose if you are deserted in the moon alone. Father told me the answer and was impressive for me. There were many items like oxygen bottles, parachute, food, light, battery, and the cal 45 automatic hand gun. I asked my father,
    "Why do you need a parachute?"
    " You need it to wrap them and carry.'
    "Why do you need a gun?"
    "Because you might be happened to meet any other unknown or hostile party of life form." (NASA was thinking about USSR or alien?')
    "Can I fire a gun in a space?"
    " Of course, just like you can fire a gun in the water, you can fire a gun in the space. The gunpowder in the cartridges have oxygen in it."
    "I got it."


    Actually, there are many issue to fire many bullets from the automatic weapon in the space. Something like a ’Vacuum deposition'. But anyway, basically, you can fire gun in the space. Technical issue will be fixed in the future, I guess.

    Thanks, Tom-san.

    Just because, I am the honorable member of the International Dimension Institute Of Technology, also known as I.D.I.O.T

    Rail gun? Ha, you have no idea how much electric power you need for those weapons.
    The entire light system in my Space battleship are flickering when the air conditioner in the shack turned on.
    It's the big problem.
    Instead, you only need a little hammer to ignite the primer to fire gun!
    The advantage is clear!
    No objection allowed.
    This is my official statement as an expert staff of Space Trajectile Usage Project International Division,

    Katsu-san , like I mentioned in my latest post - Iím pretty ignorant when it comes to shooting ( projectiles ) in space . To be honest living where I do , I really donít know much about firearms in general .

    I do know your imagination and skills to bring things to life - simply ... ahem .... Ď Blow me away ! Ď.... Thanks also for your Ď how itíll work Ď explanation - cool story

    Ged-san, The situation here about the firearms are just the same as yours.90% of Japanese people doesn't know much about the firearms and guns.
    We are strictly prohibited to own even a hunting gun without official licences.
    Moreover, we can't even touch the real gun.
    If I tried to obtain the licence, we have to start the licence of the air gun.
    After ten years possession without any trouble, we are allowed to obtain the licence of
    possessing a hunting gun or a competition gun. But never been allowed to have a hand gun like
    Glock, SIG or anything for self defense gun anyway.
    I'm the very minority. Maybe I should say I'm a kind of gun nuts.

    As we learned in training from Space Trajectile Usage Project International Division.... guns do shoot in space.

    You just need some way to counteract the force from the gun so you don't get thrown back. I am assuming this could be done with some kind of thrusters counteracting the blast

    On a side note, you have to watch out though. If shooting in orbit around a planet for example, you could theoretically shoot yourself in the back

    https://www.livescience.com/18588-shoot-gun-space.html

    Fires can't burn in the oxygen-free vacuum of space, but guns can shoot. Modern ammunition contains its own oxidizer, a chemical that will trigger the explosion of gunpowder, and thus the firing of a bullet, wherever you are in the universe. No atmospheric oxygen required.
    The only difference between pulling the trigger on Earth and in space is the shape of the resulting smoke trail. In space, "it would be an expanding sphere of smoke from the tip of the barrel," said Peter Schultz an astronomer at Brown University who researches impact craters.

    My wife loves get to the bed in a ice cold room.
    I often see a nightmare that I am wandering around the snow storm field of north pole, looking for the toilet.

    The latest progress here.

    I've made a rest of the gun turret and finished the rough part of the nose section. Then I built an atmospheric engine air intake part.
    It took whole day for just a single unit.

    Air intake



    Making a turbine wheel.









    Assembling







    And test fitting.













    The rest of the unit will be done by this weekend. I hope.

    Thanks for looking.

    Nice! And since the hull shields the intakes while the ship is traveling in space, there's not much danger of sucking a space pigeon into the engines.

    Whatever taken in this intake will be minced.
