Sky Warriors/Aircraft

There are several aircraft in Sky Warriors to choose from. Currently there are four tiers of aircraft.

There is also the aircraft's cost in either diamonds or coins. Players can spend coins to unlock the next aircraft in the list, or they can skip ahead and unlock a new aircraft using diamonds without unlocking the previous aircraft.

When promoting to next Tier the shop offers to buy one Jet with mid-level upgrades and a painting. Prices might vary depending on System and Region.
 * Tier2 - Sepecat Jaguar (9,99€)
 * Tier3 - F14 (29,99€)
 * Tier4 - Mig29 with all Parts on Level 10 and Painting (99,99€)
 * Tier5 - F/A-18 with all Parts on Level 3 and Painting (99,99€)

Statistics
Aircraft are rated in four categories:
 * Durability, or how much damage the aircraft can take.
 * Firepower, or how much damage the aircraft does with attacks.
 * Manoeuvrability, or the aircraft's ability to turn.
 * Speed, or how the aircraft flies in straight lines.

The full statistics list of all aircraft is as follows:

Upgrades
Each of the four categories - durability, speed, manoeuvrability, and firepower - can be upgraded by upgrading the airframe and its avionics.

Upgrades can only be performed via coins, though once the upgrade process begins, its upgrade timer can be skipped by spending diamonds.

Each category can be upgraded up to the Max. upgrade level of the plane. Each level giving fewer and fewer returns and taking longer. Aircraft can be used in-game during the upgrade process. At higher levels, some upgrades will begin to reduce the aircraft's performance in other areas.

The aircraft can be upgraded in five areas:


 * Cockpit upgrades improve durability and speed.
 * Fuselage upgrades improve durability.
 * Engine upgrades improve speed.
 * Weapon upgrades improve firepower.
 * Wing upgrades increase manoeuvrability.

Improvement and Cost of upgades On the example of a Tier 5 plane:
 * Up to Level 7 increase the stats 5 times stronger than from level 8 on.
 * In total Level 1-7 increase the stats more than lvl 8-33 together.
 * The increase in upgrade costs fluctuates strongly at the beginning, but in the long term levels off at around 20% per level.
 * Total costs of 876.900 coins for all 5 categories to level 7
 * Total costs of 5.653.880 coins for all 5 categories to level 12
 * Total costs of 38.023.906 coins for all 5 categories to level 20
 * Total costs of approx. 460.000.000 coins for all 5 categories to level 33

Customization
Diamonds can be spent on decals and paint jobs that provide improvements to the aircraft's statistics.

Tier 1 paints are solid colours (midnight black, cobalt blue, lush green, metallic orange, arctic white, etc.). Tier 2 paints are camoflage patterns. Tier 3 paints are aircraft specific. Paintings improve stats of Firepower and Durability.
 * Tier 1: +5%
 * Tier 2: +7%
 * Tier 3: +10%

Decals also come in two tiers, and there is one decal improving each stat:

Decals only last a certain amount of time, requiring them to be re-purchased for the bonus again.
