Interplanetary Missiles

Interplanetary Missiles destroy fixed defenses without the ordinary post-battle rebuild chance.

Base statistics

Property	Value
Structural integrity	20,000
Shield	1
Attack	25,000

These are base values before research. Structural integrity is not battle hull: combat uses one tenth of integrity. Defenses remain at the station where they are built.

Construction

Resource	Base cost per unit
Metal	10,000
Crystal	5,000
Deuterium	25,000

Requirements: Shipyard 1, Missile Silo 4.

Material Physics reduces the resource price. Use the construction screen for the modified quote and timer.

Use and limitations

Launch from the Launch Pad with enough ammunition and fuel. Astrophysics gives 4 systems of range at level 1; later levels add 0.04 before rounding, so level 10 still reaches 4 and level 14 reaches 5. IPMs cannot cross coordinate galaxies. Each missile uses ceil(100 × system distance ÷ range) deuterium; same-system launches use none. Flight time is 30 + 60 × system distance seconds. ABMs intercept first. Weapon Technology supplies +15% damage at level 1 and Missile Technology +5%; at level 2 those bonuses are +16.15% and +6.05%, multiplying independently.

Missile attacks use their own interception and damage rules, separate from fleet combat and rapidfire.
