The Ke-D2-W4000 is an aether shock cannon designed in YE 40 to be the main gun for the Yui 7-class Scout and the Chiaki-class (1B) Escort Destroyer by Kage Yaichiro to replace the Ke-D2-W3200 Shock Cannon. It was also inspired by the Ke-S3-W3900 Main Weapon Array for the Fuji-class Expeditionary Gunship and employs advances in technology pioneered in it.

It functions by emitting a scalar interference pulse that creates a small rend in the fabric of space-time. When this occurs, all energy potentials in the target area are released into normal space simultaneously, causing significant amounts of destruction. Though less powerful than full-blown Aether Shock Arrays, they are still restricted to the military and are not to be salvaged and used by civilians.
This version of the weapon has a couple of new modes. A mode based on the older Ke-D2-W2900 Phased Pulse Cannon that is pure plasma with the radiation and anti-plasma filtered out is intended for atmospheric use, while a short range spread mode is designed to be able to strike at more targets at once. Unlike that of the related Ke-S3-W4000 Aether Shock Array for the Plumeria-class (2D) Medium Gunship, this spread mode reduces the range notably in exchange for maintaining the same firepower and firing rate as the Beam mode.
| Firing Mode | Purpose | Rate of Fire | Area of Effect | Maximum Range1 | Maximum Diameter |
|---|---|---|---|---|---|
| Filtered Pulse | Tier 8, Medium Anti-Mecha | 30 pulses/minute | Single Target | 149,000,000 kilometers | 15 meters |
| Rapid Pulse | Tier 9, Heavy Anti-Mecha | 30 pulses/minute | Single Target | 149,000,000 kilometers | 15 meters |
| Beam | Tier 12, Heavy Anti-Starship | 6 beams/minute | Single Target | 149,000,000 kilometers | 15 meters |
| Spread | Tier 12, Heavy Anti-Starship | 6 spreads/minute | 30° Cone | 60.9 kilometers | 40.6 kilometers |
1Though the weapon can fire and hit a stationary target a maximum of 149,000,000 kilometers (92,000,000 miles/1 AU) away, it should be noted that the weapon's discharge would take 8 minutes and 20 seconds to travel this distance. Faster-than-light sensors on enemy ships could easily allow an enemy to dodge in this span. Due to this, it is standard practice to consider 899,376 kilometers (~0.006 AU / 3 light-seconds) to be the functional range for this weapon in Rapid Pulse or Beam Modes. When firing a Spread, however, the diameter of the shot widens with distance and the distance is far closer. This leaves an enemy less likely to be able to evade at the cost of notably reduced range.
Systems that make up this weapon were built in a modular fashion so that the sections composing the ship's main gun could be easily switched with other modules at a later time, if desired. Exchanging the main gun's systems in this fashion requires about 6 hours.
