EMP turret (weapon)

The EMP turret is a variant of the EMP gun which was seen in the war with the aliens, a later iteration than 232 (232 being the original iteration where the EMP gun was built).

It was basically a much larger dual-wielding gun turret emplacement geared towards shooting down class 9 spacecraft. It's category would be arguably class 7.

Design
The unit had an EMP cannon either side of the main housing (allowing it to either alternate shots to work better with the cooldown problems of the EMP unit or to focus fire to hit the much more agile class 9 spacecraft), and relied on mains power as a stationary turret. They were mainly positioned on land, although some were found on navy ships to promote mobility.

Capabilities
Due to the much greater availability of power and size, the units had much greater range than the EMP gun, capable of shooting down spacecraft in the mid-atmospheric point, and aided by the onboard guidance systems that allowed it to quickly track airborne targets (because the EMP gun, and thus EMP turret, used light based wave-variation propagation, it's impact was near-instant so even fast moving class 9 spacecraft, if properly targetted, could be hit).

Due to it's larger size, and greater power availability, it also lacked the cooldown issues of the much smaller EMP gun, employing rapid water-pump and similar cooling units to quickly absorb heat. As a result, it's rate of fire was significantly improved and was capable of firing shots every few minutes.

Like the EMP gun, the unit was EMP hardened and could resist direct EMP attacks.

Limitations
In the iteration, the war with the aliens, the units could not be constructed fast enough to be deployed, and makeshift EMP missiles had to be devised to counteract the production problems of the EMP turrets. Placement of the limited number of turrets was also an issue, as although navy ships were more portable, there was little to engage in the ocean-going scene (as the spacecraft targets were land-based), and navy ships had a power limitation and thus could not carry many or operate a unit to full capacity.

Although the units were EMP-hardened, the ships they were travelling on were not, and friendly fire or close-calls could result in on-board circuitry being fried and damaged, preventing ship movement. As a result, EMP turrets on navy ships had a limited firing arc to prevent damage to the ship's computers, but it narrowed the capabilities of the turret as a result.

Land-based units had limitations in that placement was stationary and thus could easily be disabled by the spacecraft with an unknown ray-based weapon. They could also be obscured by land and could be avoided by landing in spots away from the EMP turrets. They however had greater power output and thus further range.
