Phoenix

"The Phoenix, for instance, is a lightning-fast aerial harass ship which, while small, packs a serious punch against any opposing unit lacking armor. Its Ion Cannons disintegrate flesh via short wavelength energy beams, and although they can only fire upon the air, they won’t hesitate to simply use their Graviton Beam to center a ground unit right in front of their crosshairs."

The Phoenix is a protoss air to air unit in StarCraft II.

Overview
"We are the wings of justice!"

- A Phoenix pilot

A deadly spacecraft designed for aerial harassment, the Phoenix is highly maneuverable, possesses great speed, and is able to outmaneuver almost any foe. In use by 2502, the Phoenix is rapidly replacing the older Scouts and Corsairs in the role of air superiority fighters for the protoss. Phoenix patrols are a common sight on the outer rim of protoss territory, where they sweep deep space for alien threats.

The Tal'darim had incorporated the Phoenix into their arsenal by 2504.

Propulsion
The Phoenix is propelled by a compact inertial drive, which surrounds the craft in a warp field, allowing swift displacement in deep space or planetary atmospheres. Twin high-power plasma thrusters supplement the drive, making the Phoenix a formidable interceptor craft. Additionally, an energy weave covers the Phoenix's wings, giving it an appearance akin to a circuit board. In reality, it is made out of light-reactive fibers that absorb, channel, and redirect all types of energy, including the pilot’s psionic input. The weave’s primary function is to maintain the coherence of the warp field that sheathes the Phoenix’s fuselage, and enhance the ship’s stability and maneuverability when banking, rolling, or sliding at high speeds.

Armament
The twin ion blaster armament of a Phoenix is highly suited for air-to-air combat, and pack a punch against foes lacking armor. Its main armament, the blasters disintegrate their targets through short wavelength energy beams composed of negatively-charged ions though can only be used against aerial targets. These cannons are designed to allow the Phoenix to fire while on the move, but their short wavelength limits the travel distance of each shot, as well as the damage caused to heavily armored targets. The cannons' effective combat range presented a problem until the protoss began to replace the old focusing lenses with the more advanced anion pulse-crystals.

When confronted by more dangerous enemies, a Phoenix pilot can unleash a short-lived gravity beam by overloading the ship’s warp field through its inertial drive. The result is a beam composed of anti-gravity, which turns its target into a near-weightless object, immobilizing it for a few precious seconds. However, this is at the cost of the Phoenix's mobility. The beam was originally concieved as a weapon of last resort, but has since been embraced by the Great Fleet as an effective control weapon.

In 2506, the phase-smith Karax used solarite to improve the power management systems of the phoenix. This allowed the phoenix to target multiple targets with its Graviton Beam, and to use the beam without diverting power from the phoenix's weapon or propulsion systems.

Other Information
Sophisticated and lethal as the Phoenix may be, all too often a patrol squadron will find itself heavily outnumbered by zerg or terran enemies. To overcome this weakness, phoenix pilots have developed a dangerous counter-ploy. A phoenix pilot can unleash a short-lived storm of destruction by overloading its warp field through the ship's ion blasters. The area-effect discharge is devastating and can destroy a large number of enemies at once, but it comes at a price: in the aftermath the phoenix is left temporarily powerless and crippled. Wary foes have learned to flee a phoenix overload and return moments later to destroy the helpless craft. In turn phoenix pilots have begun to use staggered discharges to catch their enemies in a web of destruction. These desperate tactics are frowned upon by protoss commanders, but have become tacitly accepted as a necessity.

Game Unit
In-game, the phoenix lacks a ground attack, but makes up for this with its graviton beam. It is important to note that targets affected by the Graviton Beam can be hit by anti-air weapons, including other phoenixes. The Phoenix can move and attack simultaneously which, combined with its high speed, makes it great for harassing fleeing forces. This also make the phoenix effective as an economy raider, using the graviton beam on worker units. The phoenix is very good at destroying light air units, such as mutalisks (especially with the range upgrade). The upgraded range of a Phoenix is double that of a mutalisk, allowing for players to easily fly around mutalisks, scoring free hits without the mutalisks being able to retaliate due to their slower speed.

The Phoenix is also an effective counter unit for vikings, banshees, and void rays. However, it is weak against strongly-armored units such as the battlecruiser, carrier, and corruptor. The phoenix is ineffective against the units it counters when outnumbered. However, it can makes up for this with its fast speed.

The phoenix banks when it turns.

Legacy of the Void
In the single-player campaign of Legacy of the Void, the phoenix no longer requires energy to use Graviton Beam, which instead has a thirty second cooldown. The phoenix is also able to move and attack after using Graviton Beam, and Graviton Beam can be set to auto-cast. The Aiur variant of the phoenix has the passive ability "Double Graviton Beam," which levitates an additional nearby enemy ground unit when the phoenix uses its Graviton Beam.

These enhancements overall make the phoenix a much more offensive and aggressive unit than before, with a small number of them able to incapacitate a substantial number of enemies and attack them while they are helpless. Compared to the other starfights in the compaign, the corsair and mirage, the corsair's disruption web is more useful for attacking enemy bases and controlling terrain, and the mirage is a more defensive unit.

Co-op Missions
Artanis is able to build phoenix in Co-op Missions. They are Artanis' only air unit until he reaches Level 11 and unlocks the tempest. Artanis unlocks upgrades for his phoenix at Level 12.

Strategies
The Phoenix can lift anti-air units like the queen with the Graviton Beam ability rendering them vulnerable and helpless against void rays or other Phoenix.

When grouped with void rays, the two ships complement each others' weaknesses and become a formidable fleet, with void rays firing at heavily-armored targets and ground targets while Phoenixes fire at poorly-armored targets.
