True. The Douglas DC-3 had about the same leading edge sweep as the Messerschmitt Me-262, and for the same reason. To keep teh center of lift close to the center of gravity.

It was the first model airplane I built, some time in the late 1960s, and ever since I’ve thought it the best looking fighter ever made, rivaled only by the P-51 and F-16. The proportions and visual balance of the F-86 are just right.

Several other airplanes had swept wings prior to the F-86, such as the Dunne biplanes. But, as you reply, the sweep was used to rectify CG and stability and control issues, not for high-speed flight.

Perhaps your statement would be more correct to say “The XP-86 was unlike any airplane before it. It was the first airplane to incorporate a swept wing specifically for high-speed flight.”

Good question, but that’s the info that I found. Later models had teh “6-3” wing, which replaced the slats with an extended leading edge.

The leading edges of the Me 262 wings were swept aft 18.5°, this was done to keep the wing aerodynamic center in correct relation to the airplane’s center of gravity, as was the wing of the Douglas DC-3. The XP-86 wings were swept 35° specifically to increase the wings’ critical Mach number. This was proposed in 1945 by a NACA aerodynamicist, Robert T. Jones. Tthe German test results were not known in the U.S. at the time.

Seems questionable statement. Surely that label belongs to the Me262 which 1st flew in 1941?
