Description

The Missile Silo provides storage for Anti-Ballistic Missiles (ABMs) and Interplanetary Missiles (IPMs). It enables both defensive interception of incoming missiles and offensive strikes against enemy defenses.

Capacity

Storage Formula

Total Slots = Silo Level * 20

Slot Usage

  • Anti-Ballistic Missile (ABM): 1 slot each
  • Interplanetary Missile (IPM): 2 slots each

Capacity Table

Level Total Slots Max ABMs Max IPMs Or Mixed
1 20 20 10 -
2 40 40 20 20 ABM + 10 IPM
4 80 80 40 -
6 120 120 60 -
10 200 200 100 -

Missile Types

Anti-Ballistic Missiles (ABM)

  • Purpose: Intercept incoming IPMs
  • Required Silo Level: 2
  • Slots Used: 1
  • Cost: Metal 8,000, Crystal 2,000, Deuterium 100

Interplanetary Missiles (IPM)

  • Purpose: Destroy enemy defenses
  • Required Silo Level: 4
  • Slots Used: 2
  • Cost: Metal 10,000, Crystal 5,000, Deuterium 25,000
  • Requires: Impulse Drive 1

Missile Build Speed

Each Missile Silo level reduces build time for missiles (ABM and IPM) by 25%:

Missile Build Time = Base Time * (0.75 ^ Silo Level)

Construction Costs

Formula

Metal = 20,000 * 2^Level
Crystal = 20,000 * 2^Level
Deuterium = 1,000 * 2^Level

Cost Table

Level Metal Crystal Deuterium
1 20,000 20,000 1,000
2 40,000 40,000 2,000
4 160,000 160,000 8,000
6 640,000 640,000 32,000

IPM Mechanics

Range

IPM range is limited:

Max Range = Impulse Drive Level * 5 - 1 (systems)
Drive Level Range (Systems)
1 4
2 9
3 14
5 24
10 49

Targeting

When launching IPMs:

  1. Choose target coordinates
  2. Select specific defense type (optional)
  3. IPMs destroy defenses until depleted

Defense Priority

If no specific target chosen, IPMs target defenses at random.

ABM Defense

Interception

Each ABM intercepts one incoming IPM:

  • Automatic interception
  • ABM is consumed
  • IPM is destroyed before impact

Strategy

  • Keep ABMs stocked if you have valuable defenses
  • ABMs only protect one planet
  • Monitor hostile players' missile capabilities

Strategy

Offensive Use

IPMs are useful for:

  • Clearing defenses before attacks
  • Harassment
  • Removing shield domes

Defensive Use

ABMs protect against:

  • IPM strikes
  • Defense destruction

Build Priority

  • Silo is optional for many players
  • Build if facing missile threats
  • Build if planning missile attacks
