As NE Weaponry is the more commonly available.
And simpler to make, in both the ln-game & modding side, I thought the lack of information on the topic was a bit odd.


Anti-Fighter 'Sparrow'

The 'Sparrow', is a more armored anti-fighter Turret with a longer effective range than stock gatling turrets.
It provides a light Flak-type cloud of weapons-fire. (Flak AI aims further than the auto-detonate)
Comically, these flak shells can be intercepted or attempted to be.


Anti-Armor 'Burrow'

The 'Burrow' is a heavy defense turret armed with kinetic weaponry.
It's purpose is to blast holes in larger-vessels that get too close.
It is non-explosive.

Interception 'Lance'

The 'Lance' is a light beam weapon designed to intercept enemy missiles.
A function generally hard to manage with stock gatlings.


Siege 'Zelphyr'

The larger 'Zelphyr' acts as a 6 barreled cannon unleashing deadly explosive shells.
With a slower rotation & elevation, it has trouble tracking fast targets.
Its projectiles are explosive, and can be intercepted.
This one's model, is missing a few parts but will be coming none the less.

==============================================
As I should mention, all images (or attempted images) were taken in Blender.
As presently, these are not in-game yet, nor do I at the moment of posting have functional textures.
Mind you, these turrets use only basic colors in blender to look like that.
As well, they are darker than they should be due to my use of lighting around them.
