The Horten Ho XVIII actually were 3 different projects made by Horten brothers in 1944 in order of RLM requirement for an aircraft with a range of 11000 km (6835 miles) and a bomb load of 4000 kg (8818 lbs). None of aircraft ever archived like that. Five of Germany's top aircraft companies had submitted designs, but none of them met the range requirements for this Amerika Bomber. Horten are one of these company The Hortens were not invited to submit a proposal because it was thought that they were only interested in fighter aircraft.
The Horten brothers realised the failures and redesign the aircraft modified with 6 jumo 004 turbojet and 2 mg turret to protect the aircraft. When the meeting with Messerschmitt and Junkers engineers were helded. These engineers feel unsatsifactory with the first design-the Ho XVIIIa. After that Reimar-one of the Horten brothers feel unhappy and redeisgn it again with 2x He S011 jet engines in each of two fixed main landing gear assemblie. The prototype was proposed to test in the end of 1945 but the Allies advance was too fast and in May 1945, German surrender ended the project

Diagram of the P II
Arsenal VB-10
The Arsenal VB-10 was a French Tandem engines fighter prototypes developed during and shortly after World War II. It was a monoplane with largely orthodox configuration and retractable tailwheel the VB 10 added a second engine behind the cockpit which drove a second propeller, coaxial with and counter-rotating to the propeller driven by the engine in the nose. Although the aircraft was first designed (and indeed ordered) in 1940, but because of French occupation, the aircrafts could not flown until Europe was freed .But then, the Amee de air changed their favor on the jet technology and age of piston engine was over so the project was cancelled in 1948 and all 6 prototypes were scrapped.

Dewoitine /Sud Est SE 580
In 1944, when France been freed , the Aeronautic Manufacturing National Societies or SNCA try to built a new type of fighter based on the project of the SNCA du Midi M 580-an early design of SE 580 in 1940, the SE 580 wing planform-with its near mid-chord single spar and its empennage surfaces planforms-was similar to the D520, albeit the horizontal planes had slightly greater aspect ratio. Initially designed to be powered by the 24-cylinder Hispano Suiza 24Z (H type) of 2,000hp, its postwar redesign accommodated the 24-cylinder arsenal 24 H of 3,400hp. This latter engine used the cylinder blocks of the German Junkers IV12 213 engine.
Two 12.1-foot-diameter coaxial, counter-rotating propellers were to be utilized for propulsion.
One thing was sure is 2 prototypes were ordered but they were not complete because the project was cancelled when the Amee de Air( French airforce) focus more on jet fighters along with it competitor-the Arsenal VB-10 shortly thereafter.

- Powerplants:Hispano Suiza 24Z(2x Hispano Suiza 12Z)

Supermarine type 327 Spito
The Supermarine type 327 is a proposed twin engineed version of the successful Spitfire which was entered production later. A mock up were built for testing but later it was destroyed in fire when it was in factory.In fact it was to a design spec requested by the Air Ministry to actually replace the Spitfire which was entering service.
The 327 was an improvement version of type 324 with 6 cannons in wing root for replace 12 MG in type 324 wings.
