Missiles are the bullets of space combat. They're cheap, they're fast, they're fired in swarms, and they kill by overwhelming the target's ability to shoot them all down before one gets through.
Every spacefaring navy in the galaxy maintains missile stockpiles that dwarf their inventories of any other weapon type. A destroyer might carry eighty missiles. A battlecruiser carries thousands. A Bastion-class carries over thirty-six thousand. The math of missile warfare is simple: you throw enough at the enemy that their point defense can't stop them all, and the ones that get through deliver warheads ranging from conventional high explosive to fusion detonations measured in megatons.
"Missiles are cheap. Ships are expensive. Do the math."

| ISA Classification | Missile |
| Type | Self-propelled, semi-autonomous munition |
| Test Range | Detonation in controlled vacuum chamber |
| Optimal Range | 1,000–250,000 km |
| Operating Envelope | Effective to ~300,000 km (guidance error dominates beyond) |
| Burn Time | Sprint, <120 seconds |
| Primary Damage | Warhead-dependent |
A missile is a self-propelled munition with a guidance package, a motor, and a warhead. The motor burns hard and fast — sprint duration under 120 seconds — accelerating the missile to high velocity on a trajectory calculated to intercept the target. The guidance package makes corrections during flight, adjusting for target maneuvers and defensive countermeasures.
Missiles are semi-autonomous. Their guidance systems can track and adjust to a moving target, respond to ECM, and select optimal approach vectors, but they lack the full autonomy and AI sophistication of torpedoes. They're smart enough to hit what they're aimed at. They're not smart enough to think about it.
The warhead determines what happens when they arrive. The ISA recognizes eight standard warhead types, and the difference between a high-explosive missile and a fusion missile is the difference between putting a hole in a corvette and vaporizing everything within a kilometer.

Missiles are not precision weapons. They're saturation weapons.
The fundamental tactical principle of missile combat is volume. Point defense systems — grazer arrays, anti-missile railguns, ECM — can stop individual missiles. They can stop dozens. They cannot stop hundreds arriving simultaneously from multiple vectors.
A standard missile volley from a destroyer might be 64 missiles fired in a single salvo. A battlecruiser fires hundreds. The Bastion-class, with its 200 missile launchers, can put an entire wall of ordnance downrange in a single firing cycle. The defender's point defense has to stop every missile. The attacker only needs one to get through.
This is why navies "still bother hauling magazines of chemical ordnance despite the logistical burden," as the ISA armaments register puts it. A Grade 5 missile (1–10 kilotons) outclasses a Grade 5 grazer shot (~10 tons equivalent) by two orders of magnitude. The missile is heavier, more expensive, and requires storage — but when it hits, nothing an energy weapon can do compares.
The interplay between missile volume and point defense capability is the central calculation of space combat. Every ship has a defensive saturation threshold — the number of incoming missiles it can reliably intercept in a given time window. Below that threshold, missiles are wasted. Above it, missiles kill.
Competent fleet commanders know their enemy's defensive capabilities and calculate their salvos accordingly. Incompetent fleet commanders find out the hard way that firing twenty missiles at a cruiser with point defense rated for forty is just making expensive fireworks.
The most effective missile tactics involve launching from multiple directions simultaneously. A salvo from dead ahead is relatively easy to intercept — the point defense only needs to cover one arc. Missiles arriving from three or four vectors simultaneously force the defense to split its attention, dramatically lowering the saturation threshold.
This is why fighters carrying missiles are valuable out of proportion to their individual firepower. A fighter wing that gets behind an enemy formation and launches missiles into the rear arc while the main fleet hammers the front creates exactly the kind of multi-vector saturation that overwhelms defense.
Missiles are fired from launchers classified by throw-mass capacity. The ISA launcher classification ranges from Class 0 (0.05 ton throw-mass, point defense darts) through Class 12+ (3,200+ tons, strategic weapons). Civilian ships are limited to Class 2 launchers without special licensing; anything above that is restricted to military use.
League — League doctrine integrates missiles with grazer fire in coordinated salvos. Grazers degrade armor and defenses at long range, then missile volleys exploit the weakened areas. League ships carry substantial missile magazines — the Erebus-class super dreadnought has 240 missile tubes — but the League's smaller fleet means every missile needs to count. League missile doctrine emphasizes precision timing and coordination over pure volume.
Terrans — The Terrans embody the swarm philosophy. Terran capital ships carry staggering missile loadouts — the Bastion-class hauls 20,000 HE missiles, 8,000 nuclear, and 8,000 fusion warheads. Terran doctrine is to saturate the target's defenses through sheer volume and then keep shooting. Their industrial capacity means they can afford to expend ordnance at rates that would bankrupt smaller factions. The Terran approach to missile warfare is frequently described with the phrase "more dakka."
Freelancers — Missiles are expensive and require resupply, which makes them less attractive to Freelancers than energy weapons that just need reactor fuel. Most Freelancer ships carry small missile magazines for emergencies — enough for one or two salvos at most. Smart Freelancers save their missiles for situations where they need to hit hard and fast, then disengage before they're dry.
Missiles exist because space combat needs mass destruction that doesn't come from a beam weapon. The swarm mechanic creates a fundamentally different tactical problem than energy weapons — it's not about precision and sustained fire, it's about volume and defensive thresholds. This gives fleet engagements a rhythm: grazer exchanges at long range building damage, then missile salvos as the decisive stroke.
The enormous magazine counts on ships like the Bastion are meant to feel excessive because they are excessive. The Terran philosophy of "carry more ordnance than God" is a faction-defining trait that shapes how their battles look and feel compared to the League's more surgical approach.
