The Ketsurui Fleet Yards Aether/Scalar Submachine gun uses a spatial distortion to release condensed potentials from the aether in a coherent phased beam. Because of the subspace effects of the beam, it is ideal to compromise distortion shielding. The submachine gun can mount a bayonet-style blade and its battery magazine is housed in a bullpup-style butt. The W2913 entered service in YE 29.

• Rate of Fire (Rapid Pulse): 18 Pulses per second/1080 PPM (Automatic). Note: Effective on targets such as fighters.
• Payload The BU-M20 battery magazine holds enough power for 13500 shots on Scalar lethal or stun setting. The Scalar heavy setting consumes 5 times more power (2700 shots maximum). Aether setting consumes five times more power than scalar heavy (or 25 times more power than scalar lethal/stun) so to last a 30 seconds of constant aether fire (540 shots).

A meter-long aether saber bayonet is available for this weapon.
