Artillery Piece (Fallout 4)

The artillery piece is a constructible settlement item featured in Fallout 4, which is available after the completion of the Old Guns quest.

Characteristics
The artillery piece is a mortar capable of firing highly-damaging shells with a level of high precision and accuracy. Its maximum range however, is approximately a five sector radius, as viewed on the Pip-Boy's world map. Artillery strikes can be called down by throwing an artillery smoke grenade within range of a placed cannon.

The artillery piece does not require ammunition, but it does require a dedicated settler to operate.

Throwing a grenade in range of settlements with manned artillery pieces will trigger of salvo of 5 shots per settlement. Regardless of the number of artillery pieces in any given settlement, only one artillery piece per settlement will launch during each fire mission, even if several settlements are within range. After a successful artillery strike, there will be a short delay before the artillery is ready to fire again.

Crafting
The artillery piece can be built after recovering the artillery schematic.

Behind the scenes

 * Originally the artillery pieces were going to be laser cannons, as can be seen in the concept art.


 * Artillery seems to be heavily based on the 12-inch coast defense mortar, which was in service from the late 19th to the mid 20th centuries.

Bugs

 * Sometimes when calling in a strike, the sound of the mortar coming in can be heard, but no explosion will follow.
 * Multiple artillery pieces in one settlement causes bugs with it proper firing. The more of them you have, the worse they work. For example: 2 pieces can take more time to start firing than one or fire the same quantity of shots. The main reason - they run consequentially, not simultaneously. After they start - first artillery slowly rotates, then fires. Then second artillery begin to rotate, and this animation takes more time than delay time between shots of one piece, while the first one freezes for the time of this animation.
 * After a fire mission request, it can happen that only 1 or 2 rounds arrive at the target area. Sometimes nothing hit the target area.
 * Stealth Boy doesn't protect the player from being detected by the enemy if an artillery round hits an enemy. You get detected instantly.
