The Astraeus Super-heavy Tank is a grav-tank fielded by the Primaris Space Marines, and it’s built for one job: wrecking things. It’s the biggest vehicle in the Primaris lineup, and it trades transport space for firepower that can crack heavy armour and swat aircraft out of the sky.
What the Astraeus actually is
It’s a super-heavy grav-tank, not a transport. Where the Repulsor carries troops, the Astraeus carries guns and nothing else. That’s the whole point of the design.
The hull is enormous and held aloft by anti-gravitic generators, so it hovers rather than rolls. Layered void shields soak up incoming fire, which makes it a nightmare for assault units trying to close the distance.
Weapons and role
The main punch comes from a pair of Macro-Accelerator Cannons. Those are backed up by sponson-mounted Las-Rippers or Plasma Eradicators, a turret-mounted Heavy Stubber, and twin-linked Heavy Bolters or Lascannons on the front.
It’s a dedicated killer. Few targets can survive a full fusillade from one, and it’s especially good at shooting down aircraft, which is unusual for something this heavy.
- Primary: two Macro-Accelerator Cannons
- Sponson options: Las-Rippers or Plasma Eradicators
- Turret: Heavy Stubber
- Hull front: twin-linked Heavy Bolters or Lascannons
- Defence: layered void shields plus anti-gravitic generators
Where it came from
The Astraeus isn’t a straight copy of Belisarius Cawl’s Repulsor design. It blends his innovations with STC technology that the Minotaurs supposedly recovered during the Perun Cross Incident, a battle whose records are sealed to almost everyone, including most of the Inquisition.
Because of that murky origin, production is concentrated on distant Forge Worlds, mainly the fortress-forge of Mezoa, where Mars can’t easily keep an eye on things. That secrecy is a nice bit of lore if you like your Space Marine hardware with a side of conspiracy.
How it fits with other Space Marine vehicles
Think of it as the top of the Primaris armour tree. The Repulsor and Impulsor move troops; the Astraeus exists purely to destroy. It sits alongside Dreadnoughts and other heavy armour as the answer when you need something big and shielded on the table.
Its name comes from Greek mythology, where Astraeus was a titan married to Aurora and associated with the winds. That’s a real-world nod, not in-universe lore, but it fits a hovering war machine nicely.

- Main armament is a pair of Macro-Accelerator Cannons.
- It’s protected by layered void shields and anti-gravitic generators.

FAQ
Can the Astraeus Super-heavy Tank carry troops?
No. Unlike the Repulsor, it has no transport capacity at all. Every bit of space goes into weapons, shields, and engines.
What’s the Astraeus best at killing?
It’s a general-purpose heavy killer, but it’s especially effective against aircraft. Its macro-accelerator cannons and secondary weapons make it dangerous to almost anything.
Who can field the Astraeus?
It’s a Primaris Space Marines vehicle. Any Chapter that fields Primaris forces can theoretically use one, though the lore ties production to specific Forge Worlds like Mezoa.
