Hull Plating

Lore & Background

In the aftermath of the rebellion, the outer colonies learned hard lessons about what happens when a ship's outer shell is the only thing standing between its crew and the vacuum. Hull Plating technology, refined from pre-war industrial construction methods, bolts additional structural layers onto a ship's existing frame. It is not elegant—no sleek energy barriers, no phase-shift fields—just thicker, denser material that absorbs kinetic and thermal punishment that would otherwise crack a standard hull.

For a crew stranded light-years from any friendly port, that extra thickness is the difference between a survivable skirmish and a slow, suffocating death as oxygen leaks into the void. Engineers in the rebel-held sectors regard a fully plated hull as a baseline expectation; to fly without one is considered reckless, bordering on suicidal. The upgrade is cheap by galactic standards and widely available, which is precisely why it is almost always the first thing a captain purchases when they have spare credits.

There is a quiet, almost philosophical comfort in knowing your ship can take a few more hits. In a universe where every jump could be the last and every encounter could end in a hail of missiles, Hull Plating is the mechanical equivalent of a deep breath before the fight begins.

Reader's Guide

Hull Plating has three tiers, each replacing the previous one:

Tier I (+10 hull): The entry-level plate. Modest but meaningful, especially on smaller ships with 40–60 base hull. Grab it early if you see it in a shipyard; the cost-to-benefit ratio is excellent.

Tier II (+20 hull): Noticeably tankier. This is where the upgrade starts to feel like a real safety net against multi-ship rebel encounters. Pairs well with Hull Repair upgrades, since every point of hull you patch back is a point you won't lose permanently.

Tier III (+30 hull): The endgame plate. On a medium or large ship, this effectively adds another full 'life' worth of durability. It shifts your playstyle from cautious kiting to more aggressive engagement, since you can afford to trade hits.

Strategic synergies: Stack with Shield upgrades for layered defense (shields absorb first, plating extends the window). Combine with Hull Repair for a self-sustaining defensive loop. On weapon-heavy builds, extra hull lets you close range without fear of a single lucky missile killing you.

Hull Plating is not flashy, but in a game where hull is your true health bar, it is the single most reliable investment in staying alive long enough to finish the run.

Did You Know?

• Hull Plating is one of the few upgrades in FTL that permanently raises your maximum HP rather than providing temporary or conditional defense, making it a foundational choice for any build.
• Because the three tiers replace each other rather than stacking, a captain who buys Tier III does not also retain the bonuses of Tiers I and II—the highest tier is the only one active.
• In the FTL community, the phrase 'buy plating' has become shorthand for the universal first piece of advice given to new captains: invest in survivability before you invest in firepower.
