Defense Technology

Defense Technology

Defense Technology hardens your stationary defenses and protects part of your daily production from raids. It does not increase ship hull strength.

Overview

Property Value
Type Combat Technology
Lab Notes Research Lab level affects speed only
Effect +5% defense attack/shield per level, +15% defense hull per level, and protects 5% of daily production per level

Description

Advances in material science, bunker engineering, and hardened logistics improve both stockpile security and fixed-defense durability. Each level of Defense Technology adds 5% attack and shield strength to your defenses, raises defense hull by 15%, and protects 5% of your daily production from raids.

Effect

Ship Hull

Ship Hull = Base Hull

Defense Bonuses

Defense Attack = Base Defense Attack * (1 + 0.1 * Weapon Technology + 0.05 * Laser Technology + 0.05 * Defense Technology)
Defense Shield = Base Defense Shield * (1 + 0.15 * Ion Technology + 0.05 * Defense Technology)
Defense Hull = Base Defense Hull * (1 + 0.15 * Defense Technology)

Loot Protection

Protected (per resource) = Daily Production * 0.05 * Defense Technology Level

Defense Hull Multiplier

0 100%
1 115%
5 175%
10 250%
15 325%
20 400%

Research Costs

Combat Mechanics

Damage Order

  1. Shields absorb damage first
  2. Remaining damage hits hull
  3. Ship destroyed when hull reaches 0

Hull vs Shields

  • Shields regenerate between rounds
  • Hull damage is permanent (until repair)
  • Your bunkers and domes scale from Defense Technology

Strategy

Early Priority

Defense Technology requires Research Lab 2 and the section 2 unlock requirement:

  • Available very early
  • Cheap to research (metal only)
  • Strong early pickup if you rely on defenses or want safer stockpiles

Survivability

Higher Defense Technology means:

  • Defenses survive longer
  • Rocket launchers through domes hit harder
  • Raids leave more of your daily production untouched
  • Defensive investments scale better over time

Cost Efficiency

Defense Technology only costs metal:

  • Cheaper than Shielding (crystal heavy)
  • Good for metal-rich economies
  • Also protects part of your daily production from raids

Balance

Keep all combat techs progressing:

  • Defense Technology + Mobile Shield Technology = layered durability
  • Weapons = offense
  • Choose Defense Technology when you want stronger bunkers, not stronger ships
