Hello,

this is a Vanguard-Class Battle Cruiser from the video game "Homeworld: Deserts of Kharak".
They are heavily armored vehicles equipped with two dual cannon turrets on top. In combination with a Support Cruiser that repairs them as soon as they get damaged Battle Cruisers can tank almost everything.

A Battle Cruiser is 111 meters long which makes it just one block shorter than this Arctic Exploration Vehicle.
Being 58 meters wide also makes it wider than Bagger 288.

They are late game units and especially effective when paired with Artillery Cruisers. The Battle Cruiser protects the frail Artillery Cruiser from getting hit and the Artillery Cruiser protects the Battle Cruiser from getting outranged.

This is the second vehicle of my Deserts of Kharak collection that was built in 1.16 and was the main reason why I switched from 1.12 to 1.16.
Netherbricks just didn't look very convincing as a "dark gray" block, so I needed to be able to use polished blackstone.

When pasting the schematic, some iron trapdoors like to open themselves even though they are powered. In fact, only powered ones ever open themselves. If that happens, just place a block next to them. This will update them and they will realize that they are powered and they will close.

Enjoy!
