HighFleet – Fire Explanatory Guide

Understand how the fire spreads and how to counter.

Understand Fire

FSS Distance

At this distance, FSS may put out the fire of the big fuel tank.

At this distance, FSS cannot put out the fire on the big fuel tank. We can clearly see FSS reaches at most 6 blocks away.

What Doesn’t Burn

• Armor
• 1×1 hull pieces.
• 1×1 reinforced hull pieces.
• 1×2 hull piece.
• 1×2 reinforced hull piece.

Almost any other component and modules may catch fire, including FSS (which I find funny).

Fire Spreading

This does not spread fire. As ridiculous as it sounds, a single empty gap between tanks stops the spread completely.

Putting two layers between tanks would still allow the fire spread but only spreads after something like 10 ticks

However, this almost instantly spreads the fire.

As confusing as it seems, the armor does not burn but also does not stop the fire from spreading. The fire spreads as fast as putting two layers of regular hulls

From here we can easily see that fire spreads by contact. No contact simply doesn’t spread fire; How the blocks connect matters a lot, as 1×2 blocks and larger blocks can spread the fire insanely fast.

Even the thinnest gap stops fire from spreading. The ammo is literally in the burning tank but it doesn’t burn, at all!

Fire Prevention Planning

Based on what we’ve learned, we can design a ship that resists fire damage effectively.

Place fuel tanks with two-tile spaces between them. Then, put the FSS (Fire Suppression System) and hull on just one side. The FSS will still protect both groups of tanks because it has a good 6-block range. You can combine this with the double triangle squeeze technique to create really strong ship designs.
