Interplanetary Ballistic Missiles

Interplanetary Ballistic Missiles (IBMs) are projectiles used to destroy a planet's defenses. They are built in the Shipyard and stored in the Missile Silo, with each missile taking two slots in the Silo. Unlike in combat, defenses destroyed by Interplanetary Missiles are not rebuilt automatically.

How It Works

Interplanetary missiles are launched from the Galaxy Page. They can not be recalled. When they strike a planet, IBMs start at the weakest defenses (Missile Turrets) and work their way up to the strongest. IBMs may instead be targeted at a specific defensive weapon, in which case they will damage those first, and then any remaining damage will be dealt as if untargeted. Defenses destroyed by the IBM's will not automatically be rebuilt.

During an IBM attack, the defending world will automatically deploy any Anti-ballistic Missiles (ABMs). Each ABM on the defending world will automatically destroy one incoming IBM, preventing it from doing any damage.

Unlike normal combat units, damage from an IBM is not absorbed by defending shields. Only the hull strength of the defending unit is counted. The IBM is used up in an attack, so its shield and hull are irrelevant. Each missile does 12,000 total damage, increased by 10% per level of Weapons Tech. (i.e. a Weapons Tech Level 10 IBM does 24,000 total damage.)

As with ship-based combat, defenses destroyed by IBMs do not generate or contribute to debris fields. Neither do IBMs destroyed by ABMs generate debris fields.

IPBMs can be deconstructed by clicking on the Missile Silo link in the Buildings page.

Cost

Ore	Crystal	Hydrogen
12,500	2,500	10,000

Requirements

• Missile Silo (level 4)
• Pulse Drive (level 1)

Range

5 X Pulse Drive -1 = Number of Systems

Is the forumula:

          (5 X Pulse Drive) -1 = Range 
              or 
           5 X (Pulse Drive -1) = Range?

Note, IBMs cannot be fired from one galaxy to another.

Flight Time

30 seconds for missile strikes in the same solar system.

60 seconds additional for every solar system traversed.
