	— In-game description

The Tempest Cannon RA-2 (also known as a Long-Range Artillery Car, or Railway Storm Cannon, abbreviated as RSC) is a late-game artillery train car equipped with a 300mm Storm Cannon capable of firing large shells over long distances and across regions.

General Info

Crew

The Tempest Cannon RA-2 houses a crew of one soldier:

• Gunner (Seat 1)
  • Controls the movement, reloading, and firing of the 300mm Storm Cannon
  • Can rotate the cannon - hold RMB
  • Can see the percentage of power left in the gun (100% power = fuel tank full)
  • Able to deploy/undeploy the vehicle - press F

Armament

The Tempest Cannon RA-2 is equipped with one main armament:

• Storm Cannon
  • Mounted to the chassis (30 degree firing arc)
  • Ammo Used: 300mm
  • Range: 350-500 meters
  • Reload Duration: 5 seconds
  • Firing Duration: 1 seconds
  • Fire Rate: 10 per minute
  • Vehicle must be deployed to fire
  • Accuracy: 50m radius at minimum range up to 50m at max range (not including Wind effect)
  • Firing one shot consumes 25L of Enriched Oil inside the vehicle's fuel tank
  • Can fire across region borders
  • Unable to fire from the rapid decay zone near region borders
  • Rotating the gun consumes 3% power (3L of Enriched Oil) per degree

Inventory

It has a dedicated ammo slot that can hold one 300mm shell.

Engine & Mobility

• Fuel Tank: 100 L of Enriched Oil
  
• Can only move on Railway Tracks, must be placed on tracks with a crane
• Cannot move on its own, requires a Locomotive connected to it to be moved
• Can ram and destroy any structures (such as deployed Tripods) in its path
• Instantly destroys any unarmored vehicle in its path if there are no friendly soldiers inside of them
• Does not trigger Anti-Tank Mines
• The fuel tank is only used to fire and rotate the gun

Health & Armor

The Tempest Cannon RA-2 has 4000 HP. It has "Light Armor" resistance: it can soak small arms fire and shrapnel, and it is immune to Flamethrowers. It can soak 12.7mm machine gun fire but not for long. Heavy explosives and anti-tank weaponry are a real threat to it.
It takes 250 Basic Materials to fully repair it from 1% to 100% health with a Hammer.

Interactions

• Couple two cars together - hold Shift + E and press Couple Cars (they must be touching/close together)
• Decouple two connected cars - requires a Wrench used in the area between the two cars
• Deploying/Undeploying the vehicle - press F in the Gunner seat
  • Required to operate the artillery piece

A train can have up to 15 cars connected, Locomotive(s) included.

Production

Structure	Input(s)	Output	Time
Large Assembly Station (Train Assembly)	285 x Steel Construction Materials 95 x  Assembly Materials III 105 x  Assembly Materials IV 175 x  Assembly Materials V 8 MW of power	Tempest Cannon RA-2	72:00:00

Tier 3 Facilities must be fully researched in the Weapons and Structure Tech Tree in order to be produced.

Storage & Transport

The Tempest Cannon RA-2 cannot be stored in a Storage Depot, Seaport or Storage Ship.

It can be packaged into an extra large Shippable and transported by a Large Crane, otherwise it must be moved on Railway Tracks.

Tactics

Due to the powerful nature of 300mm weaponry, the Tempest Cannon RA-2 must be protected and used strategically, as the offensive capabilities, high ammunition cost, and production time, make them large resource sinks, as well as high-priority targets for enemies. While the ammunition for it is uncommon, the most expensive resource in this process is the enriched oil, as every shot consumes nearly a full can of enriched oil. (i.e. 100 shots require a Liquid Container's worth of enriched oil)

The primary way to adjust the weapon's range and azimuth is to move the entire vehicle. Due to the Tempest Cannon being only movable by railway tracks, special preparation and construction must be made in order to align the vehicle towards its target.

When preparing to fire it, make sure the area is well defended, as well as be on high alert for enemies attempting to stop your bombardment. Make sure you are prepared to quickly retreat if counter-artillery comes in and becomes extremely intense.

Tips

• Like all vehicles, it can refueled from any nearby fuel container/vehicle
• Like all vehicles that use large shells, they can be quickly submitted into them without accessing their inventory
  • While this can be done for all vehicles, it should only be done if they can carry/use large items

1. Equip the shell and walk up to the vehicle
2. Submit the shell into the vehicle - press V

Trivia

• The Tempest Cannon RA-2 was introduced in Update 1.50 ('Inferno'), making it the second artillery weapon in the game that uses 300mm ammunition
• Due to the powerful nature of 300mm weaponry, certain balance changes were implemented into the game to counter it:
  • The range of the Howitzer Garrison was increased from 450 meters to 600 meters in order to be able to retaliate against them. Despite this change, they do not retaliate when the shells are coming from another hex.
  • Initially, the Tempest Cannon RA-2 was able to fire within the Rapid Decay Zone, however this tactic made counter-artillery across hexes nearly impossible, as Storm Cannons cannot fire into the Rapid Decay Zone. This was changed, which made counter-artillery from other Storm Cannon weapons possible.
