Designed in YE 32 by Origin, the Z1b Anti-Ship Cruise Missile is a modification of the Z1 Cruise Missiles, updated by replacing the Antimatter rocket with an Inline Aether to Plasma Drive, giving the missile an STL speed of .36c, and technically infinite range because of the drive's fuel less nature and the small Continuum Distortion Drive. The Z1b retains all of the other, non propulsion systems of the original Z1.
| Warhead | DR(S) | Description |
| Fusion | Tier 11 | Standard missile, mounting a thermonuclear fusion warhead. |
| Cluster | Tier 9 per submunition | Releases a cluster of four inertially guided warheads, each mounting a small tactical nuclear device, meant to split up just inside a ship's point defense umbrella and make a quick suicide run to the target. Each warhead is mounted to a small antimatter rocket, accelerating the warheads at 50 km/s(squared). The cluster warheads have a maximum range of 5 kilometers |
| Antimatter | Tier 12 | Has magnet contained antimatter. The containment field is disabled on impact, causing a matter/antimatter reaction |
| Sensor | None | The warhead has been replaced with long range Optical, RADAR, LADAR, and gravimetric sensors, with a maximum range of 100 kilometers |
