Well I made this mainly for the fun of it. I was a bit tired of making ships and after being completely blown away by this creation that had a ton of cool features. I was really interestred in the airtight hangar and how it worked. This is not a super serous build but people seemed interested so why not share? Its up to you to configure it the way you want! By that, it set up to be as basic as possible.

Main hangar volume
14 blocks in width
53 blocks in depth
13 blocks in height
10 x Airvents
8 x Spotlights hanging from the main doors.
No connectors


The 16 fighter hangars
6x6 blocks in base
4 blocks in height
2x airvents per hangar







The main doors opens by triggering these timerblocks. Green to open, red closes. It works best on solid ground. The merge blocks are like magnets when within eatchers proximity and causes the whole multigrid to move along. Easily fixed by delaying the mergeblocks activation untill they nearly touch eatchother. As i stated earlier. Its up to you to edit these things to fit your needs.



A sensor is set to open and close for large or small grids. The large grid cant be too high as it might keep the door from closing due to the sensor range. Its easliy fixed by reducing the "back" value on the sensor.



Dont convert to station, but do ancor it to voxels (planets or asteroids). And
keep the moving parts clear from voxels.
Fave and like, is also recommended :P



1. Spawn it first in creative mode with no block damage (You don’t need to turn block damage off, just in case) and have a look at how the rotor heads are orientated. (They have the notch mark at 0 degrees on all rotors they are connected to. So they are all set to 0 degrees when the doors are closed.

2. While in creative mode disconnect all rotors by pressing the disconnect button. Do this on all 8 rotors at the same time. Turn of the sensor.

3. Save 2 of the smaller grids that you disconnected. 2 grids that mirror each other.

4. Spawn this blueprint in survival. Build it up. You will get a warning saying that the sub grids won’t be projected or whatever. Ignore it and project it anyways. Make sure that the sensor will not detect any large or small grids as it will dissconnect the merge blocks that keeps the doors sealed. Or just turn it off.

5. Set a timer block to “Attach” all rotors and trigger it self each second. By Doing this you can build the door arms seperatly and fly it in with a smaller ship, hold it in place until it snaps to place. Be careful, it might throw your ship around if you come in at a bad angle. Use a landing gear to lift the pieces. When all four arms are attached, turn of the timer block that you set up earlier. You don’t need it when all 8 rotors have a rotor head attached.
