Unit Types

Light air frames (naval, fighter, CAS) may be navalized, which allows them to be used on aircraft carriers. The naval versions have reduced range and speed, with an increased production cost.

All air units start with 80.0% reliability unless otherwise noted.

Statistics

Each type of plane has a number of values referred to as stats. These are described below. Most of these stats can be improved by building a variant. However, be aware that increasing one stat will adversely affect a different stat. Reference Variant and Variant Upgrading and Variant Air. Researching Air doctrine can also increase stats.

Base stats

• Maximum Speed. Maximum speed indicates how quickly a plane can fly under optimal conditions. An advantage or disadvantage in speed (or agility) can modify the damage to a plane during combat. Reference Air warfare Detection, Disruption, Damage.
• Range. Range is the maximum distance that a plane can effectively reach, perform its mission, and return to base. Lacking range to completely cover a strategic air region will result in reduced air mission efficiency. If an air wing's range does not cover the entire strategic region, then the range penalty will be proportional to the provinces that are not covered. Reference Air warfare Mission efficiency.
• Supply use. How much supply the unit consumes per day. Please read Supply on the significance of this.

Combat stats

• Air Defense. Air Defense represents how many hits a plane can take before being shot down. Reference Air warfare Detection, Disruption, Damage. Bomber defense can be increased by researching the appropriate air doctrine. Reference Air doctrine.
• Air Attack. Air Attack represents how much damage a plane can do against an enemy plane. High Air Attack also helps to counter enemy air superiority effects. Reference Air warfare Detection, Disruption, Damage.
• Agility. Agility is a plane's maneuverability. Agility affects both the ability to hit an enemy plane and to avoid being shot by an enemy plane. When two planes meet in combat, the more agile plane will be able to use a greater percentage of its air attack value. If your plane is hit by an opponent that has lower agility, then the damage to your plane can be reduced by -45%. Reference Air warfare Detection, Disruption, Damage.
• Naval Attack. Naval Attack represents how much damage a plane inflicts upon a ship. Reference Air warfare Naval Strike mission.
• Naval Targeting. Naval Targeting represents the likelihood that a plane will successfully hit a ship. The higher the naval targeting number, the more likely a surface or carrier naval bomber is to hit an enemy ship.
• Ground Attack. Ground Attack represents how much damage a plane can do to enemy divisions on the ground when helping out in combat. Reference Air warfare Close Air Support mission.
• Strategic Bombing. Strategic Bombing represents how good a plane is at dropping bombs on strategic targets such as enemy buildings, infrastructure, air bases, etc. Only Tactical Bombers, Strategic Bombers, Jet Tactical Bombers, and Jet Strategic Bombers have values for Strategic Bombing. Reference Air warfare Strategic Bombing mission.

Misc. stats

• Reliability. Reliability is a value that represents a plane's resistance to being accident prone. The lower the value, the more likely the plane will experience an accident causing loss of the plane (it is assumed that the accident was caused by inferior equipment breakdown, pilot error from poor instrumentation, weather induced equipment failure, etc.). Reference Attrition and accidents.

• Fuel Usage. Fuel usage is how much fuel a unit uses while it is operating. Air units will consume fuel while on active missions or during training. Reference Fuel.
