The AT-99 “Scorpion” Gunship -Avatar 1:48

It was built for use on Earth as terrorists and insurgents began gaining access to EMP weaponry to counter drones and other combat machines, whose combat hulls and external electronics were hardened against EMP weaponry, but the "soft" CPU remained vulnerable, short-circuiting and leaving the drone both harmless and helpless. The RDA realized it needed a manned attack craft to negate the obvious disadvantages that would come with the short-circuiting of a drone's CPU, in that a human would remain unaffected by EMP weaponry, while the Scorpion's hardened hull would remain steadfast and flying.

Navigation and imaging

FLIR, radar, IFF, no active flux shielding.

Propulsion

Dual co-axial ducted-fan rotor systems with a total of four 3-bladed prop-rotors. Twin Magnussen KE-76 turbine generators driving counter-rotating annular ceramic motors. This gives the scorpion an effective combat range of 800 kilometers at 100 mp/h cruise or 140 VNE (in pandoran atmosphere).

Weaponry

The gunships lack the basic cargo-carrying capacity and side-door guns of the Samson, but more than compensate for this with superior frontal firepower, while not lacking in the Samson's impressive speed and maneuverability.

It is armed with four gimbal-mounted .50 caliber guns with 700 rounds per minute cyclic rate of fire as close range primary weapons. The Scorpion has two pair of stub-wing pylons to carry its armament. Scorpion carries 190 TK-411 WAFAR (Wrap-Around Fin Aerial Rocket) in ten 19-tube rocket launchers. The use of the rocket varies according to the warhead that can range from tactical applications to impact-based sensor systems. Eight Hawkeye HELLFIRE (Helicopter Launched Fire-and-forget) are used to engage air-to-air targets in conjunction with the nose-mounted sensor suite.

Weapons fire is constrained by an IFF (Identification Friend/Foe) Lockout system, which prevents friendly fire incidents in complex engagements with multiple aircraft and targets. Essentially the gun refuses to fire if the projected probability cone of a friendly vehicle’s flight path will put it in the trajectory of the bullet downrange. All air vehicles in Pandoran service can track each other in a battle theater in real time, using IFF beacons, and this data is integrated into the weapons systems via IFF Lockout.

Trivia

• The Scorpion fills the role of heavily-armored VTOL weapons platform, similar to the Mil-24 Hind and AH-64 Apache.
• The Scorpion has a similar design to the UNSC Hornet VTOL gunship in Halo 3.
