AC-220 Vulture

Vulture "The Vulture is one of the UNSC's most powerful units. Basically a highly armed flying assault tank packed to the brim with weapons. The UNSC Vulture is the largest aircraft fielded by the UNSC. It is designed to deliver massive damage to enemy ground troops after air superiority has been achieved. It is slow moving but carries an impressive armament of two twin-autocannons and rocket silos that can be used to deliver a devastating barrage to enemies in a wide area. Crewed by highly trained UNSC pilot and gunners, the Vulture is an expensive unit and is usually reserved for difficult or lengthy battles. Being slow, it is vulnerable to anti-aircraft fire and enemy aircraft, but it is surprisingly resilient."

The AC-220 Gunship, more commonly known as the Vulture, is a heavy gunship used by the United Nations Space Command during the early years of the Human-Covenant War. It is a successor of the older AC-47, AC-119, AC-130, and AC-163 gunships.

Description
It is suspended by a series of ducted fans visible near the rear of the aircraft, or jet engines like the D77-TC Pelican. It is slower than other UNSC aircraft, such as the AV-14 Hornet and the AV-22 Sparrowhawk, but is armed with a number of missile artillery pods for engaging enemy ground and air units, able to fire large barrages of missiles, as well as a pair of hull-mounted autocannons.

The Vulture requires highly trained UNSC pilots and gunners, which makes them expensive to use. It lacks radiation shielding, preventing it from travelling in space. These factors, coupled with the amount of time it takes to build one, means that the Vulture is usually only reserved for difficult and lengthy battle situations.

Combat
A slow unit which can take massive amounts of damage before destruction, the Vulture is the largest ground-based aircraft fielded by the UNSC. It is able to fight against both air and ground units due to its weapon configuration,: Argent V Missile pods are used against enemy aircraft, while GUA-23 autocannons are designed for engaging ground targets. It can use its A-74 missile launcher to deliver massive damage to slow and/or static units. The Vulture's main drawbacks are its cost and the large amount of time it takes to build one; it is also vulnerable to fast counter-attacks and takes a great deal of time to repair. The Vulture should be reserved for buildings and ground units for the greatest effect. Although Vultures possess adequate anti-aircraft ordnance, they should be escorted by Wolverines to lessen the threat of aerial attacks.

In-game, the Vulture is considered an "über unit", and is constructed at the airpad, and requires six population, 900 resources, and a tech level of four. It can be upgraded with the Mega Barrage upgrade, potentially doubling its barrages' power; this upgrade is purchased at the air pad and costs 800 resource points and requires a minimum tech level of 4.

Trivia

 * For balance, the Vulture is one of only two vehicle units in Halo Wars that cannot be commandeered by SPARTANs, the other being the Covenant Scarab.
 * It is the only UNSC unit in Halo Wars that does not come out of the firebase upon deployment. Instead, it seems to descend from the, decelerating just before touching the ground.
 * The Vulture is the only air unit that isn't immobilized by a single Vampires' stasis drain, though it is still damaged and can be immobilized by multiple, synchronous drains.
