The uranium slug turret is a defensive turret with very long range and shot damage, but with a wide blind zone.

Acquisition

Uranium slug turrets can be constructed once the Uranium slug turret research project has been completed. They require 300 Steel, 30 Plasteel, 60 Uranium, 6 Components, 15,000 ticks (4.17 mins) of work, and a Construction skill of 6.

Summary

The uranium slug turret uses the autocannon weapon. In addition to the weapon's accuracy, the turret itself has a per-tile shooting accuracy of 98% or equivalent to a Shooting skill of 14. It has a maximum range of 45.9 tiles, but is unable to hit enemies within an 11.9 tile radius. These ranges are centered on the lower left tile of the turret, regardless of orientation. Despite its damage, the uranium slug turret's stopping power is almost non-existent, not even being able to stagger humans - the same is also true for the autocannon turret.

After firing 30 slugs, it needs to be reloaded with 60 uranium by a hauler. This can be adjusted in the storyteller settings, but all default difficulty settings do not alter this.

Since uranium slug turrets are large 2x2 structures, ranged attacks are twice as accurate against them. And as of version 1.3.3117, turrets don't benefit from cover. Despite displaying in the mouse-over box as such, empirical testing demonstrates that turrets do not benefit at all.^[1]

Like all turrets, they are temporarily disabled by sources of EMP, with downtime scaling to the EMP damage dealt. Unlike mechanoids, turrets do not adapt to EMP and thus can be continuously restunned.

Green is 80 - 100% of peak accuracy, blue is 50 - 80% of peak accuracy, red is below 50% of peak accuracy and grey is outside range. Gold tiles are spaced every 5 tiles. Values from 1.0.

Explosion

Uranium slug turrets have a 50% chance to explode when damaged below 20% health. The exploding turret will spark and emit a hissing sound for 240 ticks (4 secs) before exploding, dealing 50 Bomb damage in a 5.9 tile radius centered around the lower left tile of the turret. Bomb damage is multiplied 8x against walls, 4x against other impassable structures and plants, and 2x against passable buildings. All nearby raiders will attempt to move out of the blast radius before detonation.

Analysis

Uranium slug turrets are expensive, from research time to build costs to ammo costs. Uranium is difficult to come by and expensive to buy, limiting colonies that can even use one at all. The damage, while high, is overkill against most raiders, making it impractical against most enemies. It works well against centipedes or radiers with power armor.

Unlike the mini-turret, uranium slug turrets can not be moved after it is built.

Interestingly, it is more accurate at long ranges than short ranges. Raw DPS is weaker than the autocannon turrets, but this is before considering armor penetration, range, or the uranium slug's higher damage per shot, which is more likely to destroy organs.

Version history

0.19.2009 - Added.
1.1.0 - received a massive nerf to damage (75 -> 30), nerf to armor penetration (112.5% -> 70%), reduced range (49.9 -> 39.9), increased reload cost (60 -> 80 baseline) and nerf to shooting accuracy (98.8% -> 98%).
1.1.2618 - received a buff to damage (30 -> 45), increased range (39.9 -> 45.9), increased reload cost (80 -> 120) and reduced magazine capacity (40 -> 30).
1.1.2624 - received a buff to damage (45 -> 50), buff to armor penetration (70% -> 75%), and reduced reload cost (120 -> 90).
1.3.3200 - Damage increased from 50 to 55. Accuracy increased: touch 0.2 -> 0.22, short 0.3 -> 0.33, medium 0.4 -> 0.44.

-Uranium slug turrets use [[uranium slug cannon]]s. The shot is very powerful, over twice that of a [[sniper rifle]]. Armor penetration is also excellent, able to completely ignore the armor of a [[centipede]]. However, their stopping power is almost non-existent, unable to stagger [[human]]s. The uranium slug turret has a very long range of 45.9 tiles, and is quite accurate - 98% accuracy per tile, vs. 96% for other bullet-firing turrets, but they can not shoot targets within 11.9 tiles. Interestingly, it is more accurate at long ranges than short ranges. Raw DPS is weaker than the [[autocannon turret]]s, but this is before considering armor pentration, range, or the uranium slug's higher damage per shot, which is more likely to destroy organs.
