Block III Upgraded feature:
Advanced Off-axis 0.30 Minigun Gatlings(AOMG) with an effective angle of 135 degrees from off plane nose on the sides, and 90 degrees below the plane. This gives the plane similar off-axis gunnary capabilities like laser weapns could do.

In reality, it has a good potential of attacking approaching rockets by its fast speed of shooting, too, compared with laser weapns.

Although its ammunition damage is only 1/30 of conventional 20mm Gatling per ammunition, it could attack the opponents much earlier with the help of automatic-aiming off-axis Gatlings, so the opponent would get hundreds of bullets before approaching your aircraft.
With the help of auto fire control system, its effective range could be up to 3.5km, much longer than conventional fixed aerial ones. That could have similar effect with laser weapns, but much cheaper and ligjter than laser equipment. Moreover, its autoaiming capability does well at a long range, enabling it to hit target on more than 1.5 km away.
This gives it great superiority over conventional fixed weapns, and it have similar effects with laser weapn systems.
For stealth concern, the AOMG system is also retractable by activating group 8.
AOMG could achive similar targets with laser weapns.

Advantages of AOMG compared with laser weapn:
1.Much lighter, 10000 0.30 Gatling ammunitions are only about 200kgs, which is much lighter than high-power laser systems with more than 500kgs.
For example, a piece of 50kW laser saw equipment is 936kg.
2. Much smaller volume compared with Norrhop Grumman's plan to get a huge laser block on F35Bs.
3. Much more reliable technologies, with much smaller danger of failure, this plan is somehow a Phalanx close-in weapn system smaller-sized and reinstalled on planes, and its effective range wouldn't shorten ed so much because the air
4. Much less electronic power requirement compared with laser.
5. Cannot be blocked by smoke.

Disadvantages of AOMG compared with laser weapns:
Maximum range would be shorter than 5kms, while laser weapns have longer range in clear days, but:
Expected Ways of reducing the damage of laser weapns:
Add emergencial surface smoke generator on planes and rockets while realizing being targeted by laser.

Block II Advanced features:
1. Greatly improved avoinics with computer-controlled autopilot gunnery helper in activation group 6, which could help pilots to aim automatically. Flight control system is connected with fire control system.
Autopilot Tips: (1.You need to slightly adjust the pitch to increase accuracy when aiming at the target for aerial gunnery.
(2. Please never use autopilot when entering a spin or after control surface damage.
(3. Please never use autopilot in activation group 6 and system autopilot at one time. It's recommended to use autopilot in group 6, because autopilot in group 6 is more stable than system autopilot and autopilot in activation group 6 supports manually control when autopilot is on.
2. Greatly improved pilot sight, with EOTAS system for 360 degrees sight, which could even lock on the airplanes just after the fighter! EOTAS sight could be viewed on screens and helmet screens by pilots in reality.

Basic Advanced features: 1.Greatly improved aerodynamic performance and decreased drag. Flutter decreased. Upgraded engines with British O593 engine.
2.Upgraded avoinics system, radar and aiming data is now shown on the HUD. Flight data are shown on the screen.
3.A Hellfire is added in the bay. Air-2 problems fixed, the new air-2 plus is a conventional head heavy guided rocket, with a heavy head estimated at 250kg. Using late Aim7R infared and semi-radar homing rocket, with a range of 15km. Using Python4 rocket with much better turning performance which could launch at 60 degrees.
A greatly improved stealth supersonic flying wing NGAD aerodynamic concept from F106 old structure.
Nicknamed 'Angel' features:Reshaped tails both suit supersonic aerodynamic stability, supersonic trimming and turning performance, plus stealth requirements.This solve the problem of last version, which is calculated to have a bad supersonic stability.
F-106 stealth-modified and Maneuverability strengthened version with upgraded digital flight control and more realistic aerodynamics, intended for a cheap version of stealth aircraft, and it's a fairly old design. It's featured on supersonic performance compared with F35.
F106 primer plus Stealth strengthed version concept, developed from earlier F-106 stealth project. Canard and vertical stablizers are all cancelled.Stealth performance greatly improved. Thrust Vectoring is increased to 35 degrees.It uses large strake wings like F18 early versions.
Tips: 1.Activate group 3 to open drag parachutes, activate group 4 to throw the tanks, and activate group 5 to open the missile bay, deactivate group 8 to retract the 20mm Gatling.
2.If you want to improve the best turning performance maneuverability at low speed, please turn down the VTOL control block.
3. Hellfire's head is somehow light and it cannot threat large ground targets, it could deal with
clumsy planes or cars on the ground, its correct usage is using python4 rocket to lock the plane or car first, and then activate group 7 to launch the Hellfire. It's tested to destroy the Jackhammer truck.

Maximum IAS recommended to be less than 1300kmph IAS. If IAS is more than 1400kmph, the flutter would destroy the plane.
It could easily reach M2 above 8000m altitude.
Maximum tested speed M2.42 at an altitude of 20000m.
When you fight, the plane would accelerate very easily, when you turn, the plane could even
still accelerate. Please notice the IAS to avoid the plane to breakdown at a high speed.
Turning performance: Pitch rate 30 degrees per second at 600kmph at sea level, roll rate 300 degrees per second at 600kmph at sea level.If maneuver Gravity is more than 15gs, the aircraft might breakdown.
Maneuverability strengthened a lot.
