Soo... Finally the M.A Red Arrow has recieved an update, after such a long time.
About the aircraft's history:
First introduced in the mid 1950's as a civilian sports aircraft, it was quite underpowered, but was stylish and had massive wing area, so stall landings were a common practice with it. Later on, M.A recieved a contract for a ground attack jet that was capable of 2000kg of bombs, none of the current aircrafts at the time were capable of such feat, so the engineers took a civilian Red Arrow and modified it to carry such bombs, they were quite impressed at how much payload it could carry, but the aircraft was still underpowered.
next, it was tested into Mikoyanster's dead canyon, proving itself in reliability, after succesfully tanking dozens of bullets and somehow still fly.
In the following years, it recieved numerous updates, including a more rounded nose, better engines and newer air intakes.
In the 1960's, the A5 model was modified for export variant, being it the A5E, it was later sent on trials for the Vanadian airforce, but didn't win the contract.
The A series ended with the A5F, manufactured until 1972, it was equipped with the powerful P&W J52 turbojets and a better radar, aslo had the wings setted 20cm higher. it last participated in battle in the Atlantic ocean in 2019. The last examples were seen carrying AIM 54X and are now stored in a museum, for being the only 5 planes on the production to carry those missiles.(basically, an entire squad got equipped with them before the licence contract was abruptly terminated).
Meanwhile the last series of the A5F was being produced, a new prototype was being concieved, the B series, but it wasn't until 1970 when the fundings for the project were approved, and so the first B model was produced. At first glance, it was just an A model with sleek wings, but it lacked the speed that was expected, so an entire new plane was designed, taking inspiration from the successful G.91 and it's succesor, the G.91YS. the wings and tail were kept somewhat intact fromt the B1 model, but the lower part was completely redesigned, for a sleeker design. The B3 is the final model, with narrower wings than the B2, thus preventing parasite drag and accidental flips on takeoff.

Now, let's talk about the B3 model itself:
I redesigned this thing so it could share some parts with other aircrafts to reduce costs.
Introduced in the 70's and with it's latest armament from the 90's-2000's, comes equipped with a pair of GE J85-21 afterburning turbojets, producing around 16Kn dry and 21Kn in afterburner (tho this one was tweaked a bit, peaking in around 23Kn)
Main armament is a pair of old MK103 30mm autocannons, I mounted those because I already had them as subassembly and was too lazy to search stats for a modern 30mm cannon to make a new one, still, it works fine.
Landing gear was loosely based on the F-16, maybe if it was real, they would share the same rear undercarriage.
The wings are thin so they are capable of high speeds, even supersonic at high altitude, the rather low angle of the wings is compensated by a very steep entry on the wing roots, so it can go high speeds but still be capable of good maneuverability.
Since I went for a FACH thematic, the ordance was chosen according to what the Chilean airforce currently has, hence why you don't see any "Hellfire" missiles or similar stuff.

Main Parameters:
Crew: 1
Dimensions: (See table)
Empty weight: 5.490Kg
Gross Weight: 7.700Kg
Max Take-off weight: 11.000Kg (Max overload)
Fuel Capacity: 1960L / 744L Internal
2x 1.000L Drop fuel tanks Inboards and 2x 500L Drop fuel tanks outwards
Powerplant: 2x GE J85-21 (16 Kn) military thrust, (22 Kn) afterburning thrust

Performance:
Maximum Speed (at Sea Level): 963Km/h TAS
Maximum speed: 1.840Km/h TAS at 10.000m, 957Km/h IAS
Never exceed speed: 1.350Km/h IAS
Cruise speed: 872Km/h TAS, 720Km/h IAS
Service ceiling: 13.500m

Ferry range: around 3.400Km

Armament:
Canons: 2x Rheinmetall MK103 30mm
Hardpoints: 6 underwing pylons, with a total capacity of 3.300kg
Current Loadout: maximum overload ground.
Inner Pylons: 1x GPU Paveway III in each pylon
Mid Pylons: 2x AGM65 Maverick + 1x AIM120 C AMRAAM in each pylon

Controls:
normal wasdqe for flying
VTOL down: flaps
AG1: Afterburner
AG3: airbrakes
AG4: tailhook
AG7: Parachute.

Notes:
1)Ferry range will vary from IRL to SP, because SP engines consume way too much fuel.
2) The cannons should be more blended with the fuselage, but had to put them outwards because of bullet collision, as they are both air-to-air and air-to-ground.
3) This aircraft complies with M.A rigurous endurance tests, which include flying with missing tailerons/parts of wing or missing an engine.
4) I'm very sorry for surpassing the parts limit, but such level of detail requires some sacrifices, especially since the armament adds quite a lot of parts.
