Heavy Rocket Engine
The Heavy Rocket Engine is one of the components needed to create a Tier 3 Rocket using a NASA Workbench. The Heavy Rocket Engine itself is made using a standard crafting table. It is crafted the same way as a standard Rocket Engine, but uses Tier 3 Heavy-Duty Plates instead of Heavy Plating.
Note: When crafting the Heavy Rocket Engine, the button may be placed in either the top left or the top right corner.
