SU1946 stands for Simple Universe 1946, it is a series of late-WWII (or prototypes) planes plus some fiction. Planes in this series would have significantly better performance than their historical counterpart, and would receive a "Z" in their names to distinguish them from other, more accurate replicas.

History:
This is the Simple Universe version of the Arado Ar TEW 16/43-19 Nachtjäger variant (night fighter). In real life, this was an Arado prototype parallel to the Ar 234 and Me 262 proposed in 1943. The mass production of Ar 234 and Me 262 caused this plane to not be pursued.

In the Simple Universe, the long advantage from Messerschmitt aircrafts finally caused the Soviet Union to bring the case to the United Nations. They accused the Allies of "collaborating with fascists" and others, caused the Allies had to be more low-profile when handling businesses with Messerschmitt.

Meanwhile, since the Chinese Civil War is in full swing, both sides of the Cold War sensed that they don't need to further escalate the situation, and thus agreed on an arms reduction on both sides of the Iron Curtain in Europe. As a result, the newly-reborn Luftwaffe had to follow strict restrictions when acquiring their aircrafts.

With Messerschmitt became a no-go and Junkers defected, the Luftwaffe had to turn to Arado, who have a small number of prototypes to satisfy the need. Unfortunately, even after using a brand-new American engine, the Ar TEW 16/43-19Z is still somewhat inferior to both the Me P. 1107/IIZ and the Me P. 1090Z. Although it won't out-run the former and can't out-turn the latter, the TEW 16/43-19Z boasts superior radar facility, superior endurance, overwhelming all-round firepower, and indisputable defense.

Features:
- 3 detailed interior stations including pilot, rear gunner and navigator/radar operator
- Extreme firepower including 5 MK213s and 2 MK108s (both 30mm autocannons) firing forward, two upward-firing MK108s, and two rear-firing MK213s.
- No exposed fuel tanks at all, providing very good survivability.
- Custom wings
- Custom, two-staged landing gears
- Better range than other SU1946 planes

Interior: (these are old pictures, some parts' colors have changed since)
Pilot's seat

Rear Gunner/Co-pilot's seat

Navigator/radar operator's seat

Performance:
Speed: about 1900 km/h at sea level
Agility: around 5-6 seconds to turn 360 deg depending on flap position.

Activation groups:
AG1: Turn main landing gear (dumb-proof, if you didn't turn, the main gear will not retract)
AG2: Close nosewheel door (not dumb-proof, DON'T FIRE front guns with doors open!)
AG3: Radar switch (mostly cosmetic, only one switch that moves)
AG4: Nav lights
AG5: Not used
AG6: Rear gun master switch
AG7: Upward gun master switch
AG8: Front gun master switch
VTOL: Radar frequency selector on the radar panel
Trim: Downwards for flap, upwards for spoiler.
Cam 1: rear gunner seat
Cam 2: Navigator/Radar operator seat
Cam 3: Upward firing gun sight
Cam 4: Rear gun periscope

Takeoff procedure:
Flap down-> 15% power-> pull up at 100mph/160kph give or take -> AG1 on -> gear up -> AG2 on
Landing:
AG2 off -> gear down -> AG1 off -> flap down -> touchdown at about 300 km/h -> brakes (spoilers are optional but suggested for very short landings like on carriers or in Ice Base)
