First off, please check out the videos of this fighter during its test phase:

The A-13 TwinFang is the evolution of the A-10 Warthog, aka. tank buster. Utilizing similar survivability construction, the A-13 has twin engines, mounted high and highly protected towards the middle of the aircraft. The engines have aerodynamic armor plating to protect them from many types of fire. The main body of the aircraft is protected by the cannon-wings.

Cockpit:

The A-13 pilot sits in the standard crew pod/ejection unit, which has two articulated 7in Active Matrix LCD Screens. Flight control and throttle are located on the right and left arm rests respectively. In addition to this basic setup, the A-13 cockpit features no glass, but instead, a fully enclosed multi-panel OLED screen system to display the outside world to the pilot. This system allows for immediate target ID, intelligent zooming, into a target area, and of course different view modes allowing the pilot to make the most of the available conditions, for example night-vision with color correction. The helmet features targeting information, along with selectable optional information, similar to the TA4F tactical helmet featured in other projects.

Weapons:

The A-13 is first and foremost, armed with devastating Twin GAU-7/X Harbringer 30mm cannons, a higher ROF successor to the famed GAU-8/A Avenger on the A-10. Featuring a slightly different construction, and a 6000 Rds/min firing rate, the Harbringer is capable of ripping just about anything to shreds with only one volley. In addition to the Harbringer cannons, the A-13 has universal weapons harness capability, and can utilize most air-to-air or air-to-ground weaponry. Standard armament consists of 18 HMM31 High Maneuverability short range missiles, located in two missile pods on the back of the aircraft, and 8 HMM41 medium range missiles mounted on the underside of the intermediate wings. It can carry 4 HMM70s or mix and match with HMM41's and 70's.

The HMM31-A A is for ""Air"". The HMM31-A is a variant on the HMM31-G featured on the M977B Adirondack. An anti-missile missile, the HMM31-A has a slightly smaller payload than a standard ground unit HMM31, instead of packing a huge punch, the HMM31-A uses a radial explosive configuration. When the HMM31-A's target is in range it auto-detonates just before impact, causing the target to do the same from the shockwave and fragmentation. One or two HMM31-A's will be launched per threat, based on the threat's tracking system. AWACS and other battle intel. will relay threat information to the flight control computer to determine the threat's technology. The first HMM31 will be on an intercept course. If the threat is a High Maneuverability type, it can and will dodge the first interceptor, however, the second interceptor will intervene here, placing it self in the most logical escape trajectory of the threat, both missiles detonate, with fragmentation, causing damage or explosion to the threat. HMM31-A's are short range, with a max range of 3km. Threat detection however occurs well beyond the missiles effective range, well beyond visual range.

The HMM41 is designated as an Air-Air missile, however, can be used as an Air-to-Ground missile. Depending on the target. It has a max range of 24km. The HMM70, the 41's long-range cousin, has a range of over 60km.

The A-13 can carry payloads up to 17,000lb. While its overall payload is less than the A-10, the A-13 can still carry a considerable amount of weapons. The lower-payload rating takes into consideration 3000 rounds of ammunition loaded.

Engines: Twin General Electric TF35-GE-112-A

Unlike the TF34-GE-100(in use in the A-10), the 112-A(for short) features afterburning capability. It is the afterburner; in combination with the vectored thrust nozzle and rotating engine cluster, which gives the A-13 STOL capability. The 112-A also features higher performance and lighter weight than the 100. Each 112-A produces 13,095lbs of thrust. The aircraft itself weights in at 17,000lbs. It's combat weight is less than 1:1 when fully loaded, however, achieving a combat weight of 1:1 or better is possible based on armaments.

STOL take off. The A-13 can utilize both CTOL, and STOL techniques. STOL requires the usage of the vectored thrust nozzle, and pivoting engine cluster in unison to get the plane off the ground.

The A-13 is highly maneuverable due to the vectored thrust nozzles, as well as the bird-flap system on the wings. Basic maneuvers shown are: high-speed bank, half loop, flying inverted, with a barrel roll.

Targeting:

Utilizing AWACS, Satellite, and the onboard AGX-90 an AESA system (Active Electronically Scanned Array) radar, high resolution imagery, as well as Target Acquisition is made possible in milliseconds by the computer, and displayed in either of the two MFD's, or can be shown on the cockpit screen itself. A sub component of the AGX-90, the IAS-B6 uses FLAMS (Forward Looking Active Multi Spectral) radar to generate imagery relayed to the pilot, from IR to natural to false color imagery, IAS stands for Image Actualization System. Similar to the LANTIRN system, IAS-B features hands-off terrain tracking, as low as 150-200ft AGL, and contains IR, Laser, and optical designators.

In addition to the HMM31 anti-missile system, there are two stacked chaff dispensers, containing 2 chaffs each. Linked to an automatic chaff dispenser system, provide additional defense.

Flight Control:

The GHK-Astron Mk. III is a sophisticated flight control computer featuring a triple redundant fly-by wire system. When in harmony with the IAS-B, terrain following at up to 800mph is possible.
