Several companies responded, and in May 1946 Convair (then still Consolidated Vultee) won with their proposal for a [Vous devez être inscrit et connecté pour voir ce lien]-powered aircraft with a 45-degree [Vous devez être inscrit et connecté pour voir ce lien] under USAAF [Vous devez être inscrit et connecté pour voir ce lien] Secret Project MX-813.
However, [Vous devez être inscrit et connecté pour voir ce lien] testing demonstrated a number of problems with this design.

Re: Convair XF-92
Looking for solutions, Convair came across the work of Dr. [Vous devez être inscrit et connecté pour voir ce lien], who had come to the United States as
part of [Vous devez être inscrit et connecté pour voir ce lien].
Before and during the war, Lippisch had worked on a variety of delta-wing aircraft, first as low-speed gliders, and later as high-speed interceptors.

Lippisch had concluded that the delta-wing was a natural design for supersonic flight, as the highly swept leading edge remained free of the[Vous devez être inscrit et connecté pour voir ce lien] off the front of the aircraft. He had plans to develop this as the [Vous devez être inscrit et connecté pour voir ce lien], but progressed only to a unpowered glider example, the [Vous devez être inscrit et connecté pour voir ce lien].

Re: Convair XF-92
The P.13 design consisted of two large triangles joined together.
One formed the main structure and wing, the other was the vertical stabilizer and cockpit.
The only deviation from the triangular layout was an oval air intake at the nose, and round nozzle at the rear.
The engine was powered by [Vous devez être inscrit et connecté pour voir ce lien] dust stored in a large rotating disk, the odd power source being a solution to the twin problems of lack of petroleum and manufacturing capability in Germany at the time the design was being proposed.

Re: Convair XF-92
Convair took up Lippisch's work, redesigning it for jet power using the 1,560 lbf [Vous devez être inscrit et connecté pour voir ce lien] assisted by a battery of six 2,000 lbf liquid-fueled rockets.
The engine layout was rather portly and would not fit cleanly into the wing of the original P.13 layout, forcing a redesign.
The new layout placed the engine in a seemingly oversized cylindrical fuselage, moving the pilot out of the triangular
rudder into a separate cockpit centered in the middle of the fuselage, serving double duty as a [Vous devez être inscrit et connecté pour voir ce lien] for the engine intake.

The basic layout of the fuselage was very similar to the [Vous devez être inscrit et connecté pour voir ce lien] design, although the M.52 did not use a delta wing.
The rudder, no longer serving as the cockpit as well, was reduced in size.
The new design was presented to the [Vous devez être inscrit et connecté pour voir ce lien] in 1946, and was accepted for development as the XP-92.

Re: Convair XF-92
In order to gain in-flight experience with the delta wing layout, Convair suggested building a smaller prototype, the Model 7002, which the USAAF accepted in November 1946.
The design was similar in general layout as the original, but by placing the pilot in a conventional cockpit at the front, instead of centered in the fuselage, the resulting aircraft looked considerably less odd.

In order to save development time and money, many components were taken from other aircraft; the main gear was taken from an [Vous devez être inscrit et connecté pour voir ce lien], the nosewheel from a [Vous devez être inscrit et connecté pour voir ce lien], the engine and hydraulics were taken from a Lockheed [Vous devez être inscrit et connecté pour voir ce lien], the ejector seat and cockpit canopy were taken from the cancelled [Vous devez être inscrit et connecté pour voir ce lien], and the rudder pedals were taken from a BT-13 trainer.

Construction was well underway at Vultee Field in [Vous devez être inscrit et connecté pour voir ce lien] when [Vous devez être inscrit et connecté pour voir ce lien] took over the Vultee
plants in summer 1947.
The airframe was moved to Convair's plant in [Vous devez être inscrit et connecté pour voir ce lien], and completed in the autumn.
In December it was shipped without an engine to [Vous devez être inscrit et connecté pour voir ce lien]'s [Vous devez être inscrit et connecté pour voir ce lien] for wind tunnel testing.
After testing was completed, the airframe was returned to San Diego, where it was fitted with a 4,250 lbf. Allison J33-A-21 engine.

Operational history
In April 1948 the XF-92A was shipped to [Vous devez être inscrit et connecté pour voir ce lien], later to become [Vous devez être inscrit et connecté pour voir ce lien].
Early tests were limited to taxiing, although a short hop was made on 9 June 1948.
The XF-92A's first flight was on 18 September 1948 with Convair test pilot Ellis D. "Sam" Shannon at the controls.
After company testing, the aircraft was turned over to the USAAF on 26 August 1949, with the testing being assigned to [Vous devez être inscrit et connecté pour voir ce lien] and [Vous devez être inscrit et connecté pour voir ce lien].
