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.

This is the Simple Universe version of the Messerschmitt Me P.1102/5. Set to be Messerschmitt's response to the Soviet and Chinese Communists' strategy of using strong ground attack support to penetrate air defenses and attack before Allied fighters can respond. It received positive response, and the Chinese Nationalists' navy (ROCN) also purchased some of them.

The Me P.1102/5Z features 3 engines in a unique configuration, a pair of highly-swept swing wings (from 15 degrees to 50 degrees), and a unique landing gear configuration. Since the documents from the Second Simple Universe War didn't specify the weapons, the engineers decided to let the 1102/5Z to carry a pair of 55mm MK112 autocannons to fit their ground attack role in China.

Performance:
Speed: 2340 km/h at sea level (wings retracted)
Agility: approx. 11.4 seconds to turn 360 degrees at sea level @ 2000 km/h (wings extended)

Armaments:
2x 55mm MK112 Autocannons (4000 damage, 5 rounds per second, 594m/s muzzle velocity)
14x pivoted hardpoints that would automatically adjust according to wing position, including:
8x hardpoints for large munitions (in secondary camouflage color)
6x hardpoints for small munitions (in black)
Armored sections: main fuel section from behind the cockpit until the tail cone.

Activation groups:
AG1: swing wing (default is retracted)
AG2: wing landing gear angle adjustment
AG3-6: free for other assignments
AG7: arresting hook

A few introduction on how to actually fly this:
1. extend your wing and adjust wing gears to extended positions before taking off. activate AG2 and then AG1 to do this.
2. ALWAYS fly with AG2 activated before retracting the landing gear and until landed with wings in extended state.
3. Due to Simple Planes physics, the plane actually flies faster with wings extended, so in reality there actually isn't a point to make the swing wing at all, just pretend that you need to retract them above mach 1 to prevent breaking or something.
4. on minus G, the pivoted pylons would collide with the rotators, supposedly it won't break just for that but avoid such maneuver.
5. carrier landing on extremely high speeds (>600 km/h) could cause the front engines to hit the flight deck.
6. To get the ROCN paint job, simply go to the paint job menu, and change the top left color to: 9th notch from the right for the color, 4th from the left for hue (deep navy blue); then set the color on the dead center (3rd color in the 2nd line) to: 12th from the right (color), 9th from the left (hue). you can also try your own color scheme by changing these two colors as they consists of all the main parts of the plane whose color can be freely changed.

Q&A:
Q1: Why such a weird landing gear configuration? It's not historical.
A1: because the historical landing gear configuration would expose the main landing gears directly behind the blast zone of the front engines. It's not gonna cause any problem in SP though. This configuration is also used in Wargaming's depiction of the Me. P.1102B in World of Warplanes.

Q2: Why using the pivoted pylons? they are shaking!
A2: Because according to the story, this is supposed to be an attack aircraft/strike fighter. For this reason I tried to make it carry more than 13 hardpoints (I mistook the number for the HGIIIZ as 13, it actually has 11). But things not always go as planned...
"Last time we want a super fast heavy fighter and instead got an excellent dogfighter, now we want an attacker and instead got an even faster heavy fighter," said a Messerschmitt engineer who wishes to stay anonymous.
For the shaking issue it seems to be normal when holding heavy loads like Cleaver missiles. They won't break, but don't ask them to stay dead still, we're asking them to do 100+Gs after all.

Q3: I'm confused, just what is the "correct" takeoff procedure?
A3: On the ground and when stopped: Activate AG2-> Activate AG1-> Takeoff -> Gear up -> Deactivate AG1
When about to land: Activate AG1 -> gear down -> land -> taxi to spot -> deactivate AG1 -> deactivate AG2.
The aircraft is dumb-proof so don't worry if you're not flying it "correctly". It would at most cause the wing landing gear to be exposed out of the wing during flight.

Q4: Why different paint scheme from other SU1946 Chinese Nationalist planes?
A4: The ROCAF paint scheme was inspired by the XA-3 Tzu-Chung attacker prototype currently on display in Chenkungling, while the ROCN paint scheme was inspired by modern ROCN SAR helicopters.

Mods Used: 20mm Hispano Suiza autocannon, overload, fine tuner.
